15 Chapter 1 Installing ATCLink This chapter describes the process of installing ATCLink on a Windows PC. The following topics are discussed in detail in this chapter: An overview of the installation process, on page 6. How to prepare the software environment for the ATCLink install, on page 7. A detailed procedure to install ATCLink, on page 12. The basics of how to connect ATCLink to a traffic controller, on page 14. Configuring an Ethernet Connection to the Controller, on page 15. Configuring a Serial Connection to a Controller, on page 22. ATCLink Operating Manual 5

16 Chapter 1 Installing ATCLink OVERVIEW In order to install and utilize ATCLink, you will need a PC composed of Windows compatible hardware that is running either the Windows 2000 or Windows XP operating system. ATCLink is not yet approved for operation under Windows Vista. Table 5 ATCLink system hardware requirements Minimum Ideal Processor Intel P4 or equivalent, or better Intel P4 or equivalent, or better Processor Clock speed 1.2 GHz 2.0 GHz+ RAM 512 MB 1 GB+ Free Disk Space 150 MB 2 GB+ Optional items Either a Ethernet or serial port A USB port The operation of the software also requires a communications path to one or more of Peek Traffic s ATC family of traffic controllers, via either direct serial or Ethernet connections. The Peek Traffic ATC family of traffic controllers includes the ATC-1000 Advanced Traffic Controller, the ATC-2000 Advanced Transportation Controller, and phases 1 and 2 of the ATC Controller (NY CBD version) known as ASTC controllers, or CBD controllers. The operator can opt to work in an offline mode, meaning that no live connection is currently active with a controller. But this is only really possible if he or she is planning to work on a controller database that has been stored in memory which will later be synced to the controller via a live connection, or if the user is planning to define and export controller programming to a USB thumb-drive. Most other operations within the software require a live connection to a traffic controller. Because of this, the software will assume, by default, that a connection to a controller is desired, so it will attempt to make such a connection unless you tell it, during each session within the software, that you do not wish to connect to a controller. (The steps to work offline are described in the Working in Offline Mode section, starting on page 33.) Before live communications with an ATC controller can be achieved, the PC will also need to be configured with Microsoft s SNMP service add-on for Windows. The steps to install this service are described later in this chapter. 6 ATCLink Operating Manual

17 Preparing for the Installation PREPARING FOR THE INSTALLATION To prepare your PC or laptop for the ATCLink installation, you should check the following features of your system. Operating System The software requires a Windows compatible computer running Windows 2000, Windows XP (Professional versions), or Windows 7 Professional. ATCLink is not approved for operation under Windows Vista, nor is it approved for use with 64 bit versions of these operating systems. Configuring the SNMP Manager If this is the first time the PC will host ATCLink, you will probably need to install the SNMP manager on your system. To accomplish these steps, you will need to have Administrative access to the computer, and either the Windows installation CDs or the.cab files of the Windows installation. Important You do not need to install the Windows SNMP Manager on the PC if you will only be connecting to intersections via Ethernet. The SNMP manager is only required by ATCLink if you will be making Serial connections to your intersection controllers. 1. Check to see whether the PC already has the SNMP service configured. The easiest way is to right click on My Computer and choose Manage Figure 1 The My Computer management dialog box 2. Double-click on Services and Applications ATCLink Operating Manual 7

18 Chapter 1 Installing ATCLink Figure 2 Services and Applications window 3. Double-click on Services Figure 3 Windows Services list 4. Check to see if the SNMP Service is shown in the list. If it is, proceed to step 13. Otherwise, install it using the following procedure: 5. Open the Control Panel and choose Add or Remove Programs 8 ATCLink Operating Manual

At this point, the PC will request the Windows installation disk required for the SNMP files. Insert the disk, or point the installer at the local copies of your Windows installation.cab files. 10. Complete the installation following the onscreen instructions. 11. Go to the Start Menu and open the Settings list. Then choose the Control Panel. 12. Under Administrative Tools, choose Services 13. Scroll down and right mouse click on SNMP Service. 14. Select Properties. 15. Select the Security tab. 10 ATCLink Operating Manual

21 Preparing for the Installation 16. Make sure public is in the Community field with READ CREATE in the corresponding rights field. If not, then edit the existing field or add a new one. The Community name is case sensitive, be sure to use public and not PUBLIC or Public. This completes the installation and configuration of the SNMP service. ATCLink Operating Manual 11

22 Chapter 1 Installing ATCLink INSTALLING THE SOFTWARE This procedure describes the steps to actually install the ATCLink software onto the PC. The installation is simple and automated. Important Do not run the software install until the IP Address has been set and the SNMP manager has been configured on the PC. Important If you are installing to a PC that already has an earlier version of ATCLink installed and you wish to preserve the intersection, user account and password information from the previous installation, it is a good idea to back up the ATCLink main database (astc.mdb in the Program Files\Astc\Database folder) and the user database ( UserDatabase.mdb in the same location) prior to starting the following procedure. The following procedure describes the ATCLink installation: 1. Insert the ATCLink Installation CD into the CD-ROM drive of the computer. 2. If autorun is working on this drive, the Install CD interface should appear automatically. If autoplay is not configured for this CD-ROM drive on this computer, open a Windows Explorer window and navigate to the drive. Locate the start.exe file and double-click it. This will open the installation CD interface. 3. From the main menu, click on the large Install ATCLink button. 4. If you have a previous version of ATCLink installed on your system, the installer will detect this and present you with a screen to modify, repair, or remove the previous version. It will not permit you to proceed with the install until you have un-installed the previous version of ATCLink. When you uninstall ATCLink using the Installation CD interface, the database will be preserved. When you then run the installer again to install the new version of ATCLink, it will detect the old database and export its intersections to individual.mdb database files. You will need to import these intersection files back into ATCLink after you have completed the install. 5. If this is a new install, follow the on-screen directions. 6. When the installation is complete, click the Finish button. 7. You can use the Install CD interface to view the ATCLink release notes, or some documentation concerning related products. 8. Close the Install CD menus. 9. Go into the Windows Start menu and choose Programs > ATCLink 12 ATCLink Operating Manual

23 Installing the Software 10. When the application opens, you will be asked for a user name and password. If you are working with the Administrator version of ATCLink, the default value is USTC_ADMINISTRATOR for both fields. (The fields are case sensitive, and the default password must be in all capitals.) If you are working with the Manager version of ATCLink, the default login value is USTC_MANAGER for both fields. 11. When you get into the application, as a security precaution, you should create a new Administrator level user account and password, and remove the default user account. (A Manager level user account if you have the Manager version of ATCLink.) These actions can be performed using the commands on the Login menu. ATCLink Operating Manual 13

24 Chapter 1 Installing ATCLink CONNECTING TO A CONTROLLER The other side of the communications connection for ATCLink is the way in which communications are configured on your traffic controllers. A PC running ATCLink can connect to a controller via a serial connection, a local Ethernet connection, or an Ethernet connection on a network. The following section discusses the requirements to establish successful communication between the controller and ATCLink. To operate properly, an ATC family controller needs several items to be configured correctly. Without these elements, no communications (and the resulting configuration) can be achieved with the controller. More importantly, without these elements, the controller will not function in a cabinet, even when properly wired and cabled. That being said, it is important to acknowledge that all controllers do not handle communications in the same manner. Please refer to the controller s operating manual for information on communications configuration for the specific controller being configured. Note It is important to keep in mind that Individual controllers within the ATC family handle some aspects of communications differently from one another, particularly when it comes to the cabinet address. Please refer to the manual for information on communications configuration for the specific controller being configured. These are the data objects: A unique MAC address (needed for Ethernet communications) The proper cabinet address (only if it is required for your application) ATCLink installed on a PC An IP address (needed for Ethernet communications) The SNMP Manager service installed on the ATCLink PC (needed for Serial communications) A default database installed within the controller Finally, the proper modifications to the controller s database to make it work with the intersection hardware and logically service the intersection s phases The following sections briefly explain some of the required data objects listed above. It also describes how to configure the PC Ethernet adapter, and the process of establishing a connection to the controller using ATCLink. 14 ATCLink Operating Manual

25 Configuring an Ethernet Connection to the Controller CONFIGURING AN ETHERNET CONNECTION TO THE CONTROLLER ATCLink can connect to a controller a local Ethernet connection or a system Ethernet connection on a network. You must have the IP address information of the controller for which you are configuring an Ethernet connection before you begin. Consult the Controller Operating Manual for directions on how to verify the controller IP address for the specific controller you are working with. The following sections lead the user through the process of setting up serial and Ethernet connections to the controller using ATCLink. Checking for a MAC Address The MAC address is a globally unique identifier assigned to each controller s Ethernet network adapter card. The MAC address was most-likely installed in the factory. For instructions on how to check the controller's Ethernet interface MAC address, consult your controller s operating manual. Verify the Cabinet Address Different types of controllers in the Peek family of ATC controllers, work with the cabinet address in different ways. The cabinet address is necessary for ATCLink to communicate with a controller. The cabinet address is used by ATCLink to verify the identity of the controller to which it is connecting. The ATC controllers for New York City, known as ASTC controllers, or CBD controllers, expect the cabinet address to be provided to the controller by the cabinet hardware. The NEMA variants of the ATC controller line such as the ATC-1000 TS2 controllers, however, expect the user to program this information through the controller s front panel. The CBD controller has a very specific requirement for the cabinet address. At power on, or controller reset, the CBD controller automatically reads the cabinet address. If the controller s internal cabinet address does not match the address provided by the address circuit in the cabinet itself, the controller and the Malfunction Management Unit (MMU) will place the intersection into Flash. This check of the cabinet address is not a NEMA function, so it is not done as part of the ATC-1000 controller s startup. However, the ATCLink software needs this cabinet address to identify each controller to which it is communicating. The current value of the cabinet address stored in an ATC-1000 controller is displayed as the last four characters of the second row of the standard Controller Status screen. Consult the controller s operating manual for specific instructions on how to determine whether or not the cabinet address has been set. ATCLink Operating Manual 15

26 Chapter 1 Installing ATCLink Verify Controller IP Address (for Ethernet communications) The Ethernet uses 32 bit IP addressing for communication between devices where each device is assigned a unique IP Address. Data is passed between devices using a scheme in which the source and destination address are included with the data transfer. Before the controller is able to connect to ATCLink, first make sure that the Ethernet settings in the controller match the settings in the computer that is running ATCLink. Consult your controller manual for instructions to verify the IP address. 16 ATCLink Operating Manual

36 Chapter 2 Introduction to ATCLink OVERVIEW ATCLink is a Windows utility application that allows a single operator to connect to a single Peek Traffic ATC-family traffic controller at a time. Once a connection has been established, the following functions are possible using the software: Add, edit and delete user accounts within ATCLink Send new firmware to an ATC family controller Retrieve a controller database into the ATCLink database Modify the settings for a controller s database in memory Send a controller s modified database back to the controller Write controller database files to a USB thumb-drive that can then be plugged into a controller, and from there, loaded into the controller s memory Print out a controller s configuration setup Configure and run automatic alarm polling for an attached controller Sync clocks between the controller and the PC, using either as the source Latest Updates to ATCLink Version 3.10 The version 3.10 update to ATCLink added many new features to the utility: The ability to work with and edit databases for Peek Phase 2 NYC ATC-CBD traffic controllers. All objects in the phase 2 controller can now be edited in ATCLink. The ability to work with and edit the databases of Peek ATC-1000 traffic controllers A Pretimed preemption object module, allowing the user to retrieve, edit and save changes to a pretimed controller s preemption programming, supporting all of the NTCIP 1202 preemption objects, including delays, min duration, max presence, track intervals, clearance, dwell and exit intervals, and preemption interval skipping. A Transit Signal Priority module, allowing a user to retrieve, edit, and save changes to the TSP object in an ATC family traffic controller. Transit Signal Priority allows specially outfitted buses and other mass transit vehicles to take priority over the normal operation of a signal in order to get out ahead of the vehicle peleton at an intersection. ATCLink and the Peek ATC controllers have a very sophisticated, complete set of programming options for TSP operations. The Utils menu has been modified to segregate the Phase 1 controller utilities from the Phase 2 utilities. Software version has been modified to show both the version number and the build number. Previously, these fields only showed the build number. 26 ATCLink Operating Manual

37 Overview Now allow BBS communications to a PowerBack UPS unit that is attached to an ATC controller IP address can now be set on the firmware download dialog box The intersection selection dialog box now includes entry fields for the full IP address rather than just the last two octets. Added the View/Print Database utility. (The printer icon in the secondary toolbar, only available when no database module window is open.) A new firmware loader was added. Version The version update to ATCLink added these features: A parameter has been added to the USTC Misc tab of the Additional OIDs module, for controller alarm status 1. This bit encoded alarm status extends the NTCIP 1202 Unit Alarm Status, to support TSP, CIC, UPS, CMU, and USB. Nonassigned bits are reserved by U.S. Traffic Corp. The latest version of ATCLink provides the user with options regarding trap removal. Based on the Trap Data Removal parameter entered on the Control Tab of the Trap Interface, the controller will remove selected data. Once the requested the data is successfully removed the controller unit will clear its bit. All requested data will be cleared once all the bits are off (0) and this object is zero (0). Functionality has been added to define the USTC Proprietary Coordination Correction Modes for the ATCLink. Selecting Toronto mode causes the coordinator to establish a new offset using the Toronto offset correction strategy. The other option causes the coordinator to establish a new offset based on the value of the Coordination Correction Mode entered by the user. A mechanism has been added to ATCLink to allow the user to start, stop, and assign serial ports to certain NON critical processes. It also allows the user to decide if a process may restart if a fatal error occurs and determines the device a process will use during execution. The speed trap data tables have been expanded. An Entry Exit Threshold parameter has been added. Travel time differences (in percent) between the T1- T2 event and the T3-T4 event are compared to the threshold value entered. If the difference is less than or equal to the threshold, the average of the two values is stored in the 'speedtrapblockdata' object. If the difference is greater than the threshold, the shorter of the two travel times is stored in the 'speedtrapblockdata' object. Ten additional preemption parameters have been added to the Preempt Object Module. ATCLink Operating Manual 27

38 Chapter 2 Introduction to ATCLink Increased support for Daylight Savings Time changes has been added to ATCLink. DST parameters were added to the Schedule Management Object Module to allow the user determine how DST will be managed. An absolute DST transition point can be defined, relative to midnight January 1, The specific beginning and end can be programmed using the Month, Day, Date, and Time parameters. The user also has the ability to indicate that adjustments will be made by some other means, or the DST function can be disabled entirely. Added functionality gives the user the option to flash a desired output on the Input/Output map level. A flash rate may be selected for load switch green output drivers, using the top 4 bits (0xF000) of the 16 bit value. The newest version of ATCLink adds several parameters to increase flexibility in setting up Ethernet ports on the controller. Improvements have been made to the Overlap Object Module to allow more effective management of pedestrian overlaps. After selecting the phases to be included in the pedestrian overlap, the user can add a modifier that determines which phases cause a pedestrian overlap to transfer from don't walk to walk, and set the walk, and clearance times. The ability to create firmware directories for phase I and phase II. A utility has been added to enable the user to set up dedicated directories to perform firmware updates using a USB device. ATCLink s latest version supports all of the additional messages that have been added to the controller log. An alarm status parameter has been added to the ATCLink Unit Module, to monitor Offset Transitioning. The alarm status is updated whenever the Controller Unit performs an offset transition (correction in process). The newest version of ATCLinks adds an increased level of management of special functions. Special Functions parameters in the Unit Object control the special function output and status with On/OFF selections. Added ring status parameters allow users to monitor controller ring status changes resulting in more effective management. ATCLink s real-time monitoring of each controller ring provides continuous status updates of user defined parameters. A number of improvements have been made to the ATCLink user-interface to make it more user-friendly. Enlarged icons make the display easier to use. Edits to menus and parameter selections, improve appearance and functionality. 28 ATCLink Operating Manual

39 How it Works HOW IT WORKS A computer that is running the Microsoft Windows -based ATCLink software package can be connected to either the serial port (for RS-232 communications) or Ethernet port (for Ethernet communications) of an ATC family traffic controller. Consult your controller manual for information regarding which ports support NTCIP protocol. Serial port RS- 232 communications requires the use of a null modem cable, while Ethernet ports require either a crossover cable for direct connection to the controller or a standard Ethernet cable when using an Ethernet hub or switch as an intermediary device. When the controller is accessed using a laptop computer through one of these controller ports, the controller will automatically report the unique cabinet address to the software. ATCLink will then automatically access the correct Intersection parameters from the ATCLink database, as long as the controller intersection has been previously defined within ATCLink. ATCLink is used to send and receive databases from the controller. It can also be used to edit fields in the current database. This combination of editing a database and sending it to the controller means that ATCLink functions as a programming tool for the Peek ATC family of controllers. ATCLink allows a controller unit s operation to be configured using the Windows interface rather than the front panel interface of the controller hardware. These are the parameters that ATCLink can modify when connected to a compatible controller: Set the controller s time from the PC s clock Set the PCs time from the controller s clock Download firmware to the controller Save firmware to a USB key so it can be loaded on the controller using the front panel USB ports Retrieve a database from the controller Send a database to the controller Modify the controller s database in the PCs memory and send this to the controller Edit and maintain a list of controllers with their associated comms settings and databases View the operation of the intersection of an attached controller Poll one or more controllers for alarms Duplicate an intersection s database within another controller The databases mentioned here are the collections of parameters that each controller needs to control an intersection. Each intersection s controller will have a database associated with it. ATCLink was designed to manage these databases. The Intersection List display is designed for the first steps of this process. Once the structure of the database is configured, the process of setting up and editing the database parameters is completed through other displays, discussed in Chapter 3 Using the Interface, starting on page 35. ATCLink Operating Manual 29

40 Chapter 2 Introduction to ATCLink Database File Formats ATCLink was written in Microsoft Visual C++ and utilizes numerous Microsoft Windows system functions. Some of these system functions use database functions that are similar to Microsoft Access, a database program. ATCLink itself is not built on top of Microsoft Access but only uses similar function calls. When the user exports an intersection database from ATCLink, the file will have the filename extension of.mdb which is identical to the filename extension of any file saved from Microsoft Access. Do not try to open the intersection database from Microsoft Access since that database program will not have the knowledge of NTCIP, the ASTC MIB, or understanding of traffic control. These files contain all read/write variables as well as read only variables that were created for or received from the ASTC controller. Please note that Microsoft Access does not need to be present on the computer where ATCLink is to be installed. Intersections may be saved to storage using two different file formats. The first is with the filename extension of.mdb as already described. The second is with a filename extension of.blk. This file format is created using NTCIP data blocks. This is the same as the data stream that is sent or received by ATCLink from the ASTC controller. This file format is used whenever the user wishes to send or receive data from the controller using a USB memory device. These two file formats are not interchangeable such that an exported intersection database that has the filename extension of.mdb cannot be used on the USB memory device for downloading to the controller through the controller s USB port. In a similar manner a file that was saved using the.blk extension cannot be imported into ATCLink from the same Windows screen as a file with the.mdb file extension. The.blk files can be retrieved or saved only from the USB Window screen of ATCLink found elsewhere in this manual. With thousands of intersections being managed in some cities, it is strongly suggested that some sort of database management be instituted. With such a large number of signaled intersections, it would be prudent to implement some sort of organization by grouping interrelated intersections into folders for easy and logical access of specific intersection databases. For example, all the intersections of one major arterial corridor could be placed together into one folder named something descriptive, such as Fifth Avenue in Manhattan. Two ATCLink User Versions There are two different versions of ATCLink. There is an Administrator version which has complete access rights and privileges for database creation and modification. And then there is a Manager version which cannot change or create new databases. The Administrator version of ATCLink software is intended for use only by the NYCDOT personnel and a City-authorized party. An Administrator user not only has full read/write privilege to access any ASTC/ATC-CBD databases, but can also add or modify an Administrator or Manager user profile. All features of ATCLink described in this manual are available to any Administrator. The Manager version of ATCLink software is intended for use only by the City s maintenance contractors. This software version provides the capability of adding/modifying a Manager user profile in order for the maintenance contractor to manage their user profiles independently without the City s assistance. Under no circumstances will a manager user be allowed to log in to the Manager version of 30 ATCLink Operating Manual

41 How it Works ATCLink software as an Administrator or to add an Administrator user. The Manager version of ATCLink software gives a Manager user read-only privileges. A Manager user will be able to view, upload, download, import, export, and delete an intersection database from the intersection list, set controller time, upgrade firmware, upload logs from the controller, and read and save an intersection database on a USB memory stick. However, a Manager user cannot modify any database parameters or save an intersection database as another intersection. In the following chapters any reference to saving values to specific objects in the database of ATCLink or of the controller do not apply to the Manager version. ATCLink Operating Manual 31

42 Chapter 2 Introduction to ATCLink GETTING STARTED Access to ATCLink is controlled and secured. It requires each user to enter a user-id and password to log into the software. There are two levels of authorities, one to modify the parameters and timing plans, and one to access the upload/download and control functions. When the application is started, the ATCLink Login dialog box is displayed. Figure 17 PC Software Login Display To log in, type in the proper user name and password. These fields are case sensitive. The default value for both fields when the application is first started is USTC_ADMINISTRATOR for the Administrator version of ATCLink, and USTC_MANAGER for the Manager version. You are encouraged to modify these default settings as soon as possible after installing the software. Be sure to record your new user name and passwords in a secure location. It s also a good idea to create a backup user account. User administration is described on page 182. The Basic Process There are six basic steps to perform when using ATCLink: 1. Login 2. Choose an existing, or create a new, connection to an intersection controller, or choose to work offline. See Working in Offline Mode, on page Select a portion of the controller database to view. 4. Retrieve the data for that portion of the database either from the controller or the ATCLink database. 5. Make changes to the settings on-screen. 6. Either save the changes to the database, the controller, or export them to be stored on a USB memory device. (Or you can save to all three places.) 32 ATCLink Operating Manual

43 Getting Started Working in Offline Mode Normally, when you launch ATCLink, it will immediately and persistently display the dialog box shown in Figure 18, requesting a connection to a controller. Figure 18 ATCLink attempting to establish a connection to a controller Depending on which communications channel is defined as the default in the Communications menu, the dialog box will advise that ATCLink is trying to establish either a Serial or an Ethernet connection with the controller. If the communications connection to the controller fails, you may see a communications error message. This, too, will repeat at regular intervals. If you wish to work on an intersection database offline, that is, working on a controller database in the PCs memory without actually connecting to the real controller, you will need to deactivate these attempts to connect. That is done by clicking on the Stop/Start Automatic Polling button on the ATCLink toolbar. It looks like this: You can now work on the controller s database without being interrupted by connection warnings. ATCLink Operating Manual 33

45 Chapter 3 Using the Interface This chapter introduces the interface of the ATCLink software package. The following topics are discussed in detail in this chapter: A description of the Main Window, on page 36. An overview of the Menus, on page 37. A description of the toolbar functions, on page 40. The description view, on page 44. The status bar, on page 46. Using the Intersection List window, on page 47. Managing Module windows, on page 50. ATCLink Operating Manual 35

46 Chapter 3 Using the Interface OVERVIEW This chapter describes how to use ATCLink s general interfaces, including its main window, its menus, toolbars, and module windows. MAIN WINDOW When a valid username and password have been entered, the main window of ATCLink is displayed: Figure 19 ATCLink Main Window When you are not connected to any controller nor have any intersection database loaded in memory, this is how the interface appears. Windows appear within the main window to allow you to perform the main functions of ATCLink: Editing the intersection communications database and viewing and editing controller database object windows. By default, when ATCLink first launches, it immediately polls all pre-configured Peek ATC family controllers to see if any of them are asking for a complete database download. These ATC controllers can be set to request a complete database download. Consult your controller manual for instructions for this process. If none of them are making such a request, the main window simply waits for you to select which intersection you would like to interact with. This is done by using any of the three methods to open the Intersection List window: The Load Intersection button in the main window s toolbar Go to the File menu and choose Load Intersection Go to the Intersection menu and choose Database Edit 36 ATCLink Operating Manual

47 Main Window All of these options open the same Intersection List module, which is described starting on page 47. Menus The menus in ATCLink are modal, meaning they change depending on the situation. The additional menu commands that are added when one connects to a controller, or edits a controller database offline, are described in Table 7 on page 38. Table 6 Main ATCLink menus Menu Command Function File Keyboard shortcut alt-f View Keyboard shortcut alt-v Load Intersection Print Setup Exit NEMA Toolbar Toolbar Description View Opens the Intersection List window, used to edit controller comms setup Opens the standard Windows printer dialog box. Dumps the contents of memory and closes down ATCLink. If there are unsaved changes in memory, you will be prompted to save them. Toggles the ATCLink controller s toolbar on and off Toggles the main windows toolbar on and off This is the status bar at the bottom of the window that shows the Description tab and the Communications Status tab (showing a running log of comm. events).

Close All This closes all open object windows within the ATCLink main window. # [Window List] This is a numbered list of the currently open object windows. These can be selected to change the focus of the program. Keyboard shortcuts of alt-w, alt-<#> are also available to change between windows, based on the window s number in this list. ATCLink Operating Manual 39

50 Chapter 3 Using the Interface Toolbars Although many of the modules within ATCLink also have their own toolbars, the Main Window of the application has its own Main Window toolbar (described below). But it also gains a new toolbar when a user connects to a controller (or edits a controller database offline.) The exact controller toolbar that shows up depends on whether one is connecting to a controller that has been configured to operate as a NEMA controller, or as a pre-timed controller. Main Window Toolbar The main menu has its own toolbar, used for general data movement. The gray buttons are used for spacing, and are not used to launch any functions. Send DB from PC DB to controller Retrieve DB from controller to PC disk Start/stop auto-polling Edit Intersection List Select all fields Open Intersection List Download firmware Figure 20 Main window toolbar Store to PC database Controller Toolbars in ATCLink NTCIP Database Transaction Management Retrieve from PC database Send object to controller Export object to an external database Retrieve object from the controller When ATCLink is connected to a controller, a second toolbar appears in the window, above the main window toolbar. This provides special tools for working with an IQ ATCfamily controller. The toolbar that appears will be slightly different depending on whether you are connected to a Pre-timed or a NEMA controller. Toolbar for Pre-Timed Controllers When connected to a pre-timed controller, this is the toolbar that appears: Import object from an external database View/Print database Configuration Object Intersection Status Additional Objects Channel Object (Ethernet, MAC Unit Object addresses, etc.) updownload Blocks Schedule Management Object Pre-timed Object UPS Interface Input/Output Mapping Transit Signal Priority Trap Management CMU Interface Figure 21 Controller toolbar for pre-timed controllers 40 ATCLink Operating Manual

51 Main Window Each button opens a separate module window that allows you to retrieve, view, modify, transmit, and store the NTCIP data objects that are stored in the described data object. Toolbar for NEMA Controllers When a NEMA controller is connected to ATCLink, the toolbar buttons shown in Figure 21 appear, but an additional eight buttons also appear that provide access to the many more data objects that are typically encountered in NEMA (or any of the ATC family of) controllers. Preempt Object Report View Phase Object Detector Object Coordination Object Ring Object Overlap Object Security Object Figure 22 Additional buttons on toolbar for NEMA controllers ATCLink Operating Manual 41

52 Chapter 3 Using the Interface Quick Introduction to the Toolbar Modules The following table gives a quick description of each of ATCLink s object modules, as well as the page number of the section that provides more details about each one. Table 8 Quick overview of ATCLink modules Button Module Title Description Page Phase Object module Detector Object module Unit Object module Coordination Object module Preempt Object module Ring Object module Channel Object module Overlap Object module Security Object module Report View module Pretimed Object module Schedule Management Object module Additional OIDs module Configuration Object module Allows a user to view and edit the phase timing parameters, phase status group parameters, and perphase controls like omit, hold, and force off. Allows a user to view and edit all of the vehicle and pedestrian detector parameters, including detector alarm status, volume and occupancy settings, and SNMP detector traps. This data object contains parameters that are considered global unit parameters, such as startup flash, alarm status, auto ped clearance, special function outputs, etc. This object allows a user to view and edit coordination mode, status and control parameters, as well as the coordination pattern and split tables. This object allows a user to view and edit the parameters for up to six preemption setups. This is where ring sequence tables and ring control tables can be viewed and edited. This is where the control sources, types, and flash settings for up to 16 internal comms channels can be defined for the controller, as well as status group parameters for these channels. Allows a user to view and edit the parameter values for up to four overlaps, and their status group. This is where SNMP security values can be viewed and edited, including community names and access masks. This is where parameters can be set for event logs and event classes. If the controller will run in the more basic pre-timed mode, this is where the timings, cycle length, split times, and preemption settings are viewed and edited. This is where the controller s time, DST setting, timebased actions, day plans, and time-of-day scheduled operations can be defined and edited. This is where additional parameters that do not fit into any of the other NTCIP data objects are stored. This includes things like the device s MAC address, Ethernet settings, and New York-specific parameters. This is where the current make model and version information is stored on the controller hardware, software, OS, database, as well as other modular pieces of code ATCLink Operating Manual

53 Main Window Button Module Title Description Page UpDownload Blocks module Intersection Status module Input/Output Mapping module UPS Interface module CMU Interface module Trap Management module Transit Signal Priority Object This module allows a user to define which controller database data blocks are transferred when a user decides to save the files out to a secondary memory device, such as a USB memory device, from which they can later be loaded onto a controller. This module is only available when you have a live connection with a controller. It can be used to monitor the live operation of a controller. To see status updates in this window, you must Start automatic polling. This module is used to view and edit the values stored in the BIU input/output mapping parameters, when working in a TS2 Type 1 cabinet. These parameters can be used to view status and send commands to a cabinet UPS Battery backup system, if one is installed. This module can be used to retrieve, save, or print out the conflict monitor logs of the cabinet s conflict monitor unit. It can also be used to see the program card settings, and poll for status information from the CMU. This module allows the user to set up and monitor SNMP traps (i.e. device self-monitoring and phone home functions.) This module can be used to maximize the opportunity for transit vehicles to pass through an intersection with fewer stops ATCLink Operating Manual 43

54 Chapter 3 Using the Interface Description View The bottom of ATCLink s main window provides an optional Description View area. This area displays additional information about individual data objects and fields within a controller s database as the mouse moves over it onscreen. Additionally, a second tab in the Description View area allows you to monitor communications activity between the application and the controller. Mouse hovered over description viewer edge to resize the window Description viewer Figure 23 Description Viewer in the ATCLink Main window Notice that when the mouse is moved over the top edge of the Description Viewer, the mouse cursor changes to vertical arrows. The user can hold down the left mouse key and drag the upper edge of the Description viewer window to resize it. There are two tabs of information in the Description Viewer: a Description tab (default) and the Communications Status area. To view activity, you must select the desired tab before you begin the action. The illustration below (Figure 24) shows a typical Description display when the user floats the cursor over one of the data object fields in the ATCLink main window above. 44 ATCLink Operating Manual

55 Main Window Figure 24 Example object description in the Description tab The Communications Status area of the Description viewer (shown in Figure 25, below) displays SNMP messages that occur whenever the software attempts to connect with a controller, and also whenever the application requests data be sent to or retrieved from a live controller. Figure 25 Example Communications Status messages in the Description Viewer The Communications Status area displays the SNMP status messages that pass back and forth between ATCLink and the controller. It adds new messages to the top of the list, so you can go back through the history of messages by scrolling down through this ATCLink Operating Manual 45

57 WORKING WITH THE INTERSECTION LIST WINDOW Working with the Intersection List Window New intersection databases are created from the Database Edit selection under the Intersection menu or by clicking on the Create/Remove/Save as icon ( ) on the line below the menus. This will present the Intersection List window, as shown in Figure 27. Figure 27 Intersection List Display From the Intersection List, the user can: Edit the name, address, description of a controller, and define whether it is a Pretimed or NEMA controller. Duplicate (save as) an existing database to create a new intersection Create a database for a new intersection Delete an existing database Import or export a database. From the Menu menu, the user can: Edit the name, address, description of a controller, and define whether it is a Pretimed or NEMA controller. Duplicate (save as) an existing database to create a new intersection Create a database for a new intersection Delete an existing database Import or export a database The list of intersections in this display can be sorted by the Intersection Name, its Cabinet Address, or the type of Controller Database it uses. Just click on the column header to sort by that column. This feature makes it easy to find and select from among the configured intersections. The intersections in this list are the current ones that the operator is interested in. Note that from this list one edits only the communications settings for the intersection, not the controller s operating parameters themselves. You use this window to set up how communications are established with the controller. Once you select to interact with an intersection using this comms setup, you can then edit its parameters. ATCLink Operating Manual 47

58 Chapter 3 Using the Interface The import and export facilities allow for an unlimited number of intersections to be accessed, since configured controller intersection databases can be stored out to disk as a single file, or imported back into ATCLink for editing and sending to a controller. (Practically limited by the size of the hard drive and networked drives to which the computer has access) The following tools are available in the Intersection List window. Edit the selected intersection Save an intersection as another instance (Not used) Delete the selected intersection Create a new intersection instance Figure 28 Buttons on the Intersection List toolbar Editing the General Parameters of an Intersection The Edit icon ( ) is used to edit the description, address and whether the intersection is under pre-timed or NEMA-actuated control. Duplicating a Database The Save as icon ( ) is used to save a duplicate of the database currently resident in memory. The duplication process will not allow you to duplicate an address or description, as this data must be unique for each intersection. Create a New Intersection Database The New Intersection icon ( ) is used to create a database for a new intersection. This database has no values. All values need to be entered. An easier method would be to duplicate an existing intersection or import a previously defined intersection. Delete an Intersection s Database Export an intersection to a file Import an intersection from a file The Remove icon ( ) is used to delete an intersection from the PC database. 48 ATCLink Operating Manual

59 Working with the Intersection List Window Importing an Intersection s Database Created on a Different Computer The Import icon ( ) is used to transfer into the PC a previously created database from another computer or USB memory device. The following procedure should be followed: 1. Select the Import icon ( ). 2. Use standard Window s navigation to select first the predetermined drive and directory where the exports are saved. This method is the same used by other applications which need to read/write files under Windows. 3. If the intersection was created and exported from an older PC software version and then imported in a newer version you will be prompted with a question Synchronize the selected intersection? This is just to inform you of this situation. Answering No will cancel the import while a Yes will proceed with the import. Any new database values will then be set to default values. As of this writing there are no default values set during this operation this is for future enhancements. 4. The imported intersection will now appear in the Intersection List display. Exporting an Existing Intersection The Export Icon ( ) is used to transfer a database from the PC to another computer or to a USB memory device. The following procedure should be followed: 1. First select the intersection you wish to export from the intersection list. 2. Select the Export icon ( ). The icon will be grayed-out if an intersection has not been selected in the prior step. 3. Select Yes when prompted with the question Are you sure you want to export the selected intersection? 4. You will then be presented with a standard Window s control to navigate to the location where you want to save the exported data. This can be on any drive and in any folder of your choosing. This control will also let you create folders to help organize the files. This method is the same used by other applications which need to read/write files under Windows. 5. The file name can be any name you like so save the exports with a good description. ATCLink Operating Manual 49

60 Chapter 3 Using the Interface WORKING WITH MODULE WINDOWS The various functions for operating within ATCLink, editing controller databases, generating reports, and the other functions of the application, are handled within application modules, which open inside the Main Window. This section describes how to use these modules, in a general manner. Launching Modules To open a module, log into the application using a user account with sufficient privileges to access that module. Locate the toolbar icon, or Menu menu item that opens the desired module, and click on it. The module will open as a new window within the ATCLink Main window. There are two mechanisms that permit the user to open multiple module windows. To launch a second module after the first module has been opened, select Window > IQLink. Open a module by making a selection from the Menu menu or clicking on a module on the Controller toolbar. Repeat these steps for all successive modules you wish to open. See the Organizing Module Windows section that follows, for instructions on how move, resize, and tile the open module windows. Organizing Module Windows Module windows function as document windows within the ATCLink main window. They can be moved around and resized using the module window border and control objects. To resize a window, just click and drag on any of the window s borders. To close a module, click on the X button in its top right corner. Note Whenever you resize the Main window, ATCLink will automatically maximize the selected module so that it takes up the entire window area, but the module window remains resizable in this mode. The Windows menu provides tools for arranging and organizing your open module windows. To arrange all of the open windows into a set of horizontal windows, select Window > Tile. You can close all open module windows by opening the Windows menu and choosing Close All. You can switch between any of the open modules by either clicking anywhere within the module window you wish to use. Closing Modules To close a module window, either click on the x button in the top right corner of the window (see Figure 29), or, if you want to close all open module windows, go to the Windows menu and choose Close All. 50 ATCLink Operating Manual

61 Working with Module Windows Figure 29 Close button in a module window Context-Menus in Module Windows Most of the modules also provide drop-down menus whenever you right-click anywhere in the body of the module (but not in the title bar or border area.) Figure 30, below, shows a typical pull-down menu in a database editing module (here, it s the Coordination Object module.)

Start polling This tells ATCLink to begin asking the attached controller to update the data in the module window. Hold Description When the user moves the cursor over a cell or data field in an ATCLink database editing module, the Description section of the main window shows a description of what the field contains. If you want to lock this text so that it doesn t disappear when you move the cursor off of this field within the window, choose Hold Description. It will stay locked until you again right-click to open the context menu, and select Release Description. Select Read Only Items on the Page Makes a selection of all fields in the window that hold read-only data. Select Read/Write Items on the Page Makes a selection of the fields in the window that contain read and writeable data. Some modules have different kinds of context menus, such as the View/Print Database, which provides a context menu that provides the standard text editing tools (Cut, Copy, Paste, etc.) Some modules, like the Up/Download blocks module, do not provide any context-menu options. 52 ATCLink Operating Manual

63 Chapter 4 Manipulating Controller Databases This chapter describes the overarching techniques to work with controller databases within ATCLink. The following topics are discussed in detail: An overview of manipulating databases in ATCLink, on page 54. The importance of data cell color coding, on page 58. Retrieving data from a controller or the central database, on page 59. Sending data to the controller or central database, on page 60. Loading a default database into a controller, on page 61. Downloading a Database to the Controller from a USB Device, on Page 64. Using ATCLink to Update Controller Firmware, on Page 66. ATCLink Operating Manual 53

64 Chapter 4 Manipulating Controller Databases WORKING WITH A CONTROLLER S DATABASE Up to this point, we have been dealing with ATCLink as a general traffic controller interaction program. However, once a connection is established with an actual piece of controller hardware, the program becomes a tool to send and receive parameters to the hardware. Data is handled within NTCIP as data objects. ATCLink also calls these data sets objects, as can be seen under the Menu menu. These are treated in the program as pages of related parameters. Each page of data may be further divided into subsets, located on separate tabs of the page. The appearance of the ATCLink interface is slightly different, depending on whether you are connected to a pre-timed controller (such as the CBD) or a NEMA phase-based controller (such as the ATC-1000 TS2 controller.) Understanding Data Handling in ATCLink Controller databases are designed around the NTCIP standard. The parameters contained in these databases are basically NTCIP-defined variables. In the language of NTCIP, each variable is tracked and handled using an OID, or Object Identifier. These OIDs are collected together into NTCIP-defined groups, or pages of data. The pages are also further subdivided into related groups of data on tabs within each module. Pages of data cannot be displayed until an intersection is loaded. The operator determines which intersection they want to view and then opens it. (This can be done either via a live connection, or by working offline, (see page 33, for details.) Once an intersection is loaded, the operator can retrieve the controller s values, save the values to the database on the computer, export the database to compressed format, and/or save the database to a controller (if one is connected). The user must keep in mind that there are several distinct memory areas where different types of data is viewed, edited and stored. The areas and types of data stored there are: the Intersection database on the computer a collection of data objects for a specific intersection which can be edited in ATCLink the working storage location in memory on the computer stored images of controller databases which can be imported to ATCLink for editing the Intersection database on the controller a specific intersection database which can be edited in ATCLink and saved to the ATCLink database on the computer, and downloaded to the controller external database files database objects, database blocks, or controller databases stored externally on a USB memory device or a remote computer 54 ATCLink Operating Manual

65 Working With a Controller s Database You will need to understand the relationship between these different memory areas to successfully operate this system. ATCLink has a variety of tools and mechanisms for handling data, based on its location. The operator must keep in mind where the desired information is stored: If the data is stored on the computer (i.e. in ATCLink s own database), the operator will need to use the get from DB tool ( ). If the data is stored on the controller, the operator must select the get from controller icon ( ). If the data is stored in an external database, the operator will need to use the upload from an External Database tool ( ). The next important item to decide is which data value to view or edit. The operator can select an individual item on a page, or use the select all icon ( ) to select all the data fields on a single module page. When an item is selected, the square around that item (the cell) will change color to blue (the cell is highlighted). This indicates which items will be impacted by the next user action. Note To perform any data manipulation action in ATCLink, you must first select at least one item and then tell the software which location you want to get it from or save it to. After selecting desired items, the operator can: Send data to the central database ( ) Get data from the central database ( ) Send data to the controller ( ) Get data from the controller ( ) Download data to an external database ( ) Upload data from an external database ( ) Important The Send data to controller and Get data from controller buttons have an additional function when the Up/Download Blocks module is open. If the Write to USB file box is checked in that module, the and buttons will result in a fast export (or fast import ) to a compressed file. You can elect to save this file on a USB thumb drive for later installation on a controller, or anywhere else on your computer s hard drive or connected network drives. ATCLink Operating Manual 55

If the operator has chosen to read data from the controller, ATCLink will automatically compare these values with the values stored in the ATCLink database. It will highlight in red those that do not match. If the values are read-only not changeable by the operator they will be shown in dark pink. The table at left summarizes these colors. (The colors can be changed by selecting Data Control Colors under the View menu item.) Figure 32 Color codes for data cells 58 ATCLink Operating Manual

69 Retrieving Data from a Controller RETRIEVING DATA FROM A CONTROLLER There are two primary modes in which most users will operate ATCLink with a controller. The main one is to connect the PC to the controller, retrieve the current settings from the device, make some changes, and store the settings back to the controller. (The secondary mode, described in the next topic, is to copy the database from one controller, modify it, and then save it to another.) This procedure describes how to do the first of these: 1. Open ATCLink. 2. Plug a cable in between the PC and the controller. This can be either a null modem serial cable, an Ethernet cross-over cable, or an Ethernet cable connected via a switch or router to the controller. 3. Go to the Intersection List (File menu > Load Intersection), choose the controller to which you wish to communicate, choose the connection type (Ethernet or serial) and connect to the device. 4. Go to the Menu menu and choose the data object you wish to retrieve from the controller. (Or you can select the object s icon from the controller toolbar.) Suppose we want the primary phase timings. In that case, we will open the Phase Object window. 5. When the object window appears, choose the Select All button from the main toolbar. (All of the cells in the window will be tinted blue to indicate that they are selected.) 6. Choose the Read Selected Data from the ASTC button. (Or you can go to the File menu and choose Read Selected Data from the ASTC.) 7. Wait a few moments while ATCLink reads the data from the controller. The time this process takes will depend on which object is selected (some objects have many parameters, some have only a few) and how fast the connection speed is. ATCLink Operating Manual 59

70 Chapter 4 Manipulating Controller Databases EDITING AND STORING DATA TO A CONTROLLER Once a controller is connected and the database has been loaded into memory, or you have opted to work offline and the database has been loaded into memory out of the central database, you can edit and manipulate the database fields, using the following steps: 1. Open the ATCLink module window used to edit the NTCIP data object you wish to modify or view. These are available either in the controller toolbar (pretimed or NEMA) and also in the Menu menu. 2. The data will appear in the object window, and the cells will be color coded green, indicating that the current value in memory is the same value stored in the controller. Read-only fields will have text set to the read-only color, as defined in the Data Cell Color Coding window (refer to page 58.) 3. To make a change to a parameter, click on the cell. If it is a simple numeric value, you can just type in a new value. But many cells present a special data editing window. Select the cell and make the selection. When a parameter is modified, the cell will change to purple, indicating that the value in memory may be different than the one stored in the controller. 4. Once you ve made all the changes within this object, choose Select All again. You must now determine what you would like to do with the data. The three options are: send the data to a controller, store the selected data to the ATCLink database, or export it to an external database. See the instructions below for each option: If you wish to save the selected data to the ATCLink database, press the Send Selected Data to PC Database button. You can also select the Send selected data to PC Database option from the File menu. If you wish to send it to the controller, make sure you are connected to the controller, and then press the Send Selected Data to ASTC button. You can also select the Send Selected Data to ASTC option. If you wish to save it to an external database, press the Download Selected Information to an External Database button, to open a dialog box. Select YES to save the selected data to an existing imported intersection in the ATCLink intersection list. Select an intersection from the dropdown box, and click the OK button. Select No to save the selected date to an existing Exported Intersection situated in a directory path. An Open File dialog box appears, allowing the user to select the file path of the external database where the data is being stored. 60 ATCLink Operating Manual

71 Loading a Default Database Into a Controller Editing and Storing Data to a Controller These steps can be used to load a default controller database onto the unit. (This is only required if the unit has no database installed, which should only occur if it has been erased, or it was shipped from the factory without a default database, which is unlikely.) These steps use the IP address, the SNMP manager and the ATCLink software. They also require a default database file supplied by Peek Traffic. One is included on your ATCLink installation CD. 1. Power the controller down and back up to load the IP address. 2. Launch the ATCLink software. 3. Choose the icon of the Floppy Disk (Create/Remove/Save As) (It is the third icon from the left on the top toolbar row.) 4. On your PC, locate the 0101.mdb file on the ATCLink installation CD (or provided by your Peek Traffic representative.) Copy the file to your Windows desktop. 5. Choose the Import icon (2 green arrows). This opens a window to allow you to choose the database to be imported. Navigate to your Windows desktop and select the 0101.mdb you just copied, and choose Open. Figure 33 Pulling in the default database 6. After the database loads, rename the intersection and change the intersection address to the one for the controller you wish to edit. 7. Close the Intersection list window. This will return you to the main ATCLink window. 8. Choose the Load Intersection icon. This opens the Select Intersection window. ATCLink Operating Manual 61

72 Chapter 4 Manipulating Controller Databases Figure 34 Selection Intersection window 9. Connect an Ethernet cross-over cable between the network card on your PC and Port 5 on the controller. Note You also have the option of creating a serial connection with the controller for ATCLink communications. At the time the intersection instance is defined in the ATCLink Intersection database, you will need to specify which COM port on the computer will be used for the serial connection. Also, you will need to make sure that the baud rate used by ATCLink matches the baud rate set for the same port on the controller. Consult the Controller Operating Manual for directions. 10. Highlight the intersection with the correct cabinet address. Be sure the Connect to Controller and the Ethernet (or Serial) check boxes are selected, depending on the type of connection you are making, and choose OK. Figure 35 Connecting to the controller over Ethernet 11. After it connects to the controller, the connection window will show the controller cabinet number and the Firmware Build Version. This window will close automatically and launch the main ATCLink window. 62 ATCLink Operating Manual

For a TS2 controller, after it restarts, the controller will default to run an 8-phase dual ring sequence. The default NEMA load provides the following data: Default Timings: Phase 1-8 Min Green = 04 Seconds Phase 1-8 Passage Time = 2.0 Seconds Phase 1-8 Yellow = 3.0 Seconds Phase 1-8 Red Clear = 2.0 Seconds Phase 1-8 Max 1 Green = 30 Seconds Phase 1-8 Max 2 Green = 45 Seconds Phase 2/4/6/8 Walk = 04 Seconds Phase 2/4/6/8 Don t Walk = 08 Seconds Phase 1 8 Minimum Recall Detector Assignments: Veh Detectors 1 through 8 are assigned to Phases 1 through 8 Ped Detectors 2/4/6/8 are assigned to Peds 2/4/6/8. Downloading a Database to the Controller from a USB Device ATCLink software is specifically designed to import and export complete database files, data objects, and firmware updates to and from the controller unit. The controller is typically connected via a live serial cable or Ethernet connection to a PC that is running 64 ATCLink Operating Manual

75 Editing and Storing Data to a Controller ATCLink. The database files can be also saved from ATCLink to a USB device and downloaded loaded to the controller via its USB port. ATCLink provides data handling options that allow the user to upload data to a USB drive functioning as a data source for the controller. One option is the Up/Download Blocks Module, discussed on page 152, which saves a compressed database file to a USB device. Data can also be uploaded to a USB device using the Export function discussed in the Exporting an Existing Intersection topic, on page 49. The following section discusses the special requirements for using a USB memory device to move database files between ATCLink and the controller. It further instructs the user in the steps needed to prepare the device for use as controller data source. Formatting a USB Device for use as a Data Source A USB memory device can function as a database or firmware source for the Peek family of ATC controllers, including ATC controllers for New York City, known as ASTC controllers, or CBD controllers. To enable a USB device to function properly: the database files must be stored in the correct compressed file format (i.e. a.blk file) the device must be formatted with the correct signature file and directory structure. Otherwise the controller will not recognize the database stored on the USB device. The Utils menu contains options which will configure a USB device with the required files. With this framework in place, the user is able to transfer controller programming and firmware files between ATCLink and the controller, via the USB memory device. Follow the steps below to prepare a USB memory device for use as a data source for a Peek ATC controller: Insert the USB device in the USB port on your computer Click on the Utils menu on the ATCLink Main Window toolbar Click on Phase 2, and then click on Write USB files and Folders to open the Save As dialog box. Select the USB Port from the "Save in" drop-down menu of the dialog box Click Save to close the dialog box. The ASTC box appears, advising: USB signature files and Folders created successfully! Note If you are working with a Phase 1 New York City ASTC or CBD controller, select Phase 1 from the Utils menu, then select either Write USB files and Folders to prepare the device to save database files, or select Write IFS files and Folders to prepare the USB device to store firmware files. ATCLink Operating Manual 65

76 Chapter 4 Manipulating Controller Databases USING ATCLINK TO UPDATE CONTROLLER FIRMWARE The basic functions of the controller and all data necessary for operation are contained internally using firmware and database parameters which are loaded to the controller. From time to time, however, as changes and improvements are made to the code, a firmware update will be required to make use of the new or improved code. Controller firmware can be downloaded to the controller via an Ethernet connection to the computer running ATCLink, or downloaded to the controller from a USB device which has been configured to function as a data source for an ATC controller. Upgrades can be delivered to you via , downloaded over the internet, or on a CD. Depending on which code you are updating you may receive one or more of the four different file types and sizes listed below:.bin files traffic application updates.wfi files a complete flash image of the controller engine board with a file size of 16 MB (16,777,216 bytes).krn files controller Linux Kernel files which are less than 4 MB.btt files controller boot files that are less than 512k.txt files informational text files Caution Firmware update is a critical process. The controller must be in diagnostic or utilities mode of operation, and the cabinet should be in flash before sending a firmware update to the controller. Before updating the controller firmware, it is imperative that you consult the controller manual. 66 ATCLink Operating Manual

77 Using ATCLink to Update Controller Firmware Updating Controller Firmware Using the ATC Firmware Loader The ATCLink Firmware Loader is a mechanism which makes it possible to download firmware upgrades to Peek family ATC controllers, including ATC controllers for New York City, known as ASTC controllers, or CBD controllers, over an Ethernet connection. Firmware upgrades cannot be downloaded from a computer connected to the controller via a serial connection. The Firmware Loader allows the user to view and edit the controller s IP address, select the firmware file to be loaded, and complete the firmware download. Firmware upgrades via ATCLink require coordination with the controller. If you are updating more than one file type, the updates will be done individually and successively. The following section explains the process of upgrading firmware for the Peek family of ATC controllers, including the CBD controller. Consult the controller manual for a detailed explanation of firmware and firmware upgrades, before you begin. It is advisable to have an auxiliary power source for the controller and the computer, to guard against a power loss during the firmware update process. Interrupting a firmware update can cause a catastrophic failure of your controller. Do not turn off the controller, do not unplug the Ethernet cable, and do not stop the host computer operation when the update is in progress. Caution Do Not interrupt a firmware download that is in progress. An incomplete download can render your controller inoperable until it is returned to Peek Traffic, Inc. for reprogramming. Follow the steps below to download a firmware upgrade to a controller over an Ethernet connection: After logging into ATCLink, access the ATC Firmware Loader dialog box, shown in Figure 40, in one of following three ways: By selecting Controller firmware update from the File menu. Select Phase 2 from the Utils menu, and click on CU Firmware Update to open the Firmware Loader dialog box. Click the Firmware Download button on the Main Window Toolbar ( ) ATCLink Operating Manual 67

79 Using ATCLink to Update Controller Firmware On the Controller 1. Verify the Controller IP address is correct. 2. Start the controller s firmware loading application on the Diagnostic Menu From the ATC Firmware Download Dialog Box on the ATCLink interface 3. Enter the controller IP address in the Controller IP field. 4. Select the firmware version to send to the controller by clicking the Select Firmware File button. The Firmware File window will automatically open the directory that contains files of the correct type. 5. Select the firmware update file from the Select Firmware File window, and click OPEN. Selecting an invalid file type will cause the update button to become inactive and the label will change to Invalid Firmware File Selected. Notice that the attributes of the selected file will be reflected in the File Size, File Selected, MD5SUM field, and the Update Button label on the Firmware Download Dialog Box. 6. Some applications may require verification of the MD5SUM code displayed in the Download Dialog Box, against the code supplied with the update. If the code displayed does not match the code supplied with your Firmware update, contact your Peek Distributor or the Peek Traffic Technical Support Department. 7. Click the Update Button to begin the update procedure. You should see a status bar that shows the progress of the update. If the controller is not ready, you will receive the message shown below in Figure 45, advising that ATCLink could not connect to the controller. Repeat steps 1, 2, and 3 above and verify that the IP address and Port information are correct. Consult your controller manual if the problem persists. Figure 41 Could not connect message displayed if the controller is not ready 8. When the update is completed successfully, the message box, shown in Figure 45, will appear to advise that the Operation Completed Successfully. Click OK. Figure 42 Update is complete ATCLink Operating Manual 69

80 Chapter 4 Manipulating Controller Databases At the Controller 9. When the update is complete, follow your controller s on-screen instructions to complete the update, or continue the process of updating additional firmware files. Note It is strongly recommended that if you are updating more than one type of firmware file, that you reboot the controller between updates. Should you encounter a problem updating your controller firmware, please contact the Peek Traffic Technical Support Department for assistance. 70 ATCLink Operating Manual

81 Using ATCLink to Update Controller Firmware Updating Controller Firmware Using a USB Memory Device The Phase 2 selection of the Utils menu contains the Write USB Files/Folders option which initializes a USB memory device with a signature file and directory structure. With this framework in place, the user is able to download the latest firmware version to the previously configured file on the USB device for uploading to the controller. To save the firmware update to a USB drive: 1. Select Phase 2 from the Utils menu, and then select the Write USB Files/Folders to open the Save As dialog box. 2. Use the Windows dialog box to browse and locate the USB drive, and then click Save. 3. An ASTC message window appears to advise USB Signature File and Folders created successfully! 4. Save the Firmware update file from the source to the USTC_firmware folder on the USB memory device. 5. The controller firmware update is now ready to be uploaded to the controller by inserting the USB memory device into the USB port on the controller. Consult the Operation Manual for your controller for instructions on uploading firmware upgrades. Note If you are working with a phase 1 ATC Controller (NY CBD version) known as an ASTC controller, or CBD controller, the steps to creating a signature file and file structure on your USB drive is slightly different. Select Phase 1 from the Utils menu, then select Write IFS files and Folders to prepare the USB device to store firmware files. Follow the procedure outlined above for downloading the firmware upgrade to the controller. Caution Make sure that you have the correct version of firmware. Only firmware that is a later version than what is currently in the CU may be used on the USB. ATCLink Operating Manual 71

82 Chapter 4 Manipulating Controller Databases PRINTING A DATABASE The View / Print Database button provides a mechanism to view, print, or save an ATCLink database to a text file. This database is view only, and cannot be edited. The View/Print Database button can display only the intersection database that is currently loaded in ATCLink. To open the View/Print Database function, select the View/Print Database button ( ) on the Main Window Toolbar (shown at right).

86 Chapter 5 Editing a Controller Database OVERVIEW In this chapter, we describe each of the 21 modules used to program and report on controller databases in ATCLink. These modules are discussed in the order they are placed in the ATCLink toolbar, from left to right. Of these modules, all but two function in the same way, as single or multi-pane database tables showing parameter values along the left edge, data group names in the column headers, and individual table cells that can be programmed based on the type of data to be stored in each. The two exceptions are the View/Print Database Module and the Up/Download Blocks Module, which are used, respectively, to generate a report based on a controller s database values, and to configure what data gets sent back and forth to a controller directly and via a USB thumb drive. Each section in this chapter describes the basic interface of the module, any special controls it uses, a description of the overall purpose, a discussion of how data is grouped in the environment, and a field-by-field listing of what the data represents. In many cases, the field-level data descriptions are taken directly from the NTCIP MIB data object standard. Note: In Phase 1, the ASTC controller was configured as a Pre-Timed controller within ATCLink, with the NEMA setup reserved for other members of the ATC controller family. However, in phase 2, the ATC-CBD controller uses all of the NEMA sections of the database as well as the Pre-timed modules, so a phase 2 CBD controler should be configured as a NEMA controller when first set up in ATCLink. This will give access to all 21 modules, rather than just the 11 available to a purely PreTimed controller. 76 ATCLink Operating Manual

87 Phase Object Module PHASE OBJECT MODULE This module allows a user to view and edit the phase timing parameters, phase status group parameters, and per-phase controls of the controller s database, including such data as green, yellow, red, and walk timings, as well as phase adjusting parameters such as omit, hold, and force off. This module can be opened in a couple of ways: By going to the Menu menu and choosing Phase Object Or by selecting the Phase Object button ( ) on the controller toolbar Figure 45 Phase Object module window This module separates the data into three tabs: Phase Table, Phase Status and Phase Control Table. Phase Table Parameters The following parameters can be defined for up to 16 phases. Phase Walk Phase Walk Parameter in seconds. This shall control the amount of time the Walk indication shall be displayed. REFERENCE: NEMA TS 2 Clause and a ATCLink Operating Manual 77

Detector Occupancy Status Detector Occupancy data collected over the Volume / Occupancy Period or Detector Unit Diagnostic Information. The value of the object shall indicate occupancy or detector diagnostic information as follows: Table 16 Detector Occupancy Status options Range Meaning Detector Occupancy in 0.5% Increments Reserved 210 Max Presence Fault 211 No Activity Fault 212 Open loop Fault 213 Shorted loop Fault 214 Excessive Change Fault 215 Reserved 216 Watchdog Fault 92 ATCLink Operating Manual

103 Detector Object Module 217 Erratic Output Fault Reserved Faults shall be indicated for all collection periods during which a fault is detected if either occupancy data or volume data is being collected. The highest numbered fault shall be presented if more than one fault is active (i.e. indicate OpenLoop rather than NoActivity). Volume Occupancy Sequence This object defines a Sequence Number for Volume / Occupancy data collection. This object is used to detect duplicate or missing reports. The value cycles within the limits of 0 to 255. This object is incremented by one at the expiration of the volumeoccupancyperiod time. Speed Trap Parameters The Traps tab in the Detector Module refers to the configuration of speed traps, and does not refer to SNMP traps, which are configured using the parameters in the Traps Management module. (See page 167.) Speed Trap Table No This object selects which speed trap to manipulate. There are 5 speed traps total. Each speed trap is a pair of adjacent detectors in one traffic lane. This design follows the operation of the Manhattan RCU but does not require the use of the RCU, nor does it require the controller ASTC Protocol object to be set to Manhattan operation. Entry Exit Threshold This object is used to specify the entry/exit threshold for the speed trap in seconds (0-255 sec.). Travel times differences (in percent) between the T1-T2 event and the T3-T4 event are compared to this value. If the difference is less than or equal to this value, then the average of the two values is stored in the 'speedtrapblockdata' object. If the difference is greater than this object's value, the shorter of the two travel times will be stored in the 'speedtrapblockdata' object. Sequence No The setting of this object begins data collection of speed trap data. (The leading and lagging detector objects should be initialized first before setting of this object.) Data collection will occur with each vehicle actuation of the detectors and will continue filling the data block buffer until a new sequence number is set. If this object is set again with the same sequence number then the same buffered data will be available as before. A new value for the sequence number will start a new collection of data and pass the buffered data to the Block Data. Leading Detector The Leading Detector object is set with the index number of the detector to be used as the first loop detector in the speed trap. Lagging Detector The Lagging Detector object is set with the index number of the detector to be used as the last loop detector in the speed trap. Block Data This is the buffered data collected by the speed traps once the sequence number has been set. There are five separate buffers, one for each of the speed traps, with 255 entries in each buffer. This data has three values, the first one for the index into the buffer, the second one for the Travel Time and the last one for the Exit Presence Time. On the 255th event of the associated trap pair the, speedtrapblockdatasequence is incremented and all 255 events are copied into this ATCLink Operating Manual 93

104 Chapter 5 Editing a Controller Database object. If speedtrapblockdatasequence is incremented by a remote device the current event records will be copied into this object immediately for a read by the remote device. Travel Time / Exit Presence Time The first value is the Travel Time (an integer of the number of 1/60 clock ticks from the leading edge of the first detector of the pair to the leading edge of the second detector of the pair.) The second value is the Exit Presence Time (an integer that is also in 1/60 clock ticks of the occupancy of the second detector). 94 ATCLink Operating Manual

110 Chapter 5 Editing a Controller Database COORDINATION OBJECT MODULE This module allows a user to view and edit controller parameters having to do with coordinated operation, including coordination mode, status and control parameters, as well as the coordination pattern and split tables. This module can be opened in a couple of ways: By going to the Menu menu and choosing Coordination Object Or by selecting the Coordination Object button ( ) on the controller toolbar 0. Toronto Figure 48 Coordination Object Module window The parameters stored in the Coordination Object have been split across three tabs in this module: Mode/Status/Control, Pattern Table, and Split Tables. Mode / Status / Control Parameters Coord Operational Mode This object defines the operational mode for coordination. The possible modes are: Table 19 Coord Operational Mode values Value Description 0 Automatic - this mode provides for coord operation, free, and flash to be determined automatically by the possible sources (i.e. Interconnect, Time Base, or System Commands) Manual Pattern - these modes provides for Coord operation running this pattern. This selection of pattern overrides all other pattern commands. 254 Manual Free - this mode provides for Free operation without coordination or Automatic Flash from any source. 255 Manual Flash - this mode provides for Automatic Flash without coordination or Free from any source. REFERENCE: NEMA TS 2 Clause ATCLink Operating Manual

111 Coordination Object Module ASC Coord Correction Mode This object defines the Coord Correction Mode. The possible modes are: Table 20 Coord Correction modes Mode other dwell shortway (Smooth) addonly Description the coordinator establishes a new offset by a mechanism not defined in this standard. when changing offset, the coordinator shall establish a new offset by dwelling in the coord phase(s) until the desired offset is reached. when changing offset, the coordinator shall establish a new offset by adding or subtracting to/from the timings in a manner that limits the cycle change. This operation is performed in a device specific manner. when changing offset, the coordinator shall establish a new offset by adding to the timings in a manner that limits the cycle change.

112 Chapter 5 Editing a Controller Database Coord Pattern Status This object defines the running coordination pattern / mode in the device. The possible values are: Table 23 Coord Pattern Status values Value Description 0 Not used Pattern, indicates the currently running pattern 254 Free, indicates Free operation without coordination. 255 Flash, indicates Automatic Flash without coordination. Local Free Status The Free modes: Table 24 Local Free status modes Mode notfree commandfree transitionfree inputfree coordfree badplan badcycletimefree splitoverrun invalidoffset failedfree other Description The unit is not running in free mode. the current pattern command is the Free mode pattern. the CU has a pattern command but is cycling to a point to begin coordination. one of the CU inputs cause it to not respond to coordination. the CU programming for the called pattern is to run Free. Free - the called pattern is invalid. the specified cycle time is not adequate to service the all phase minimum service requirements. free - the sum of the critical path splittime's exceed the programmed patterncycletime value. free - the programmed patternoffsettime value exceeds the programmed patterncycletime value. cycling diagnostics have called for Free. Some other condition has caused the device to run in free mode. Coord Cycle Status The Coord Cycle Status represents the current position in the local coord cycle of the running pattern (0 to 510 sec). This value normally counts down from patterncycletime to Zero. This value may exceed the patterncycletime during a coord cycle with offset correction (patterncycletime + correction). Coord Sync Status The Coord Sync Status represents the time since the system reference point for the running pattern (0 to 510 sec). This value normally counts up from Zero to the next system reference point (patterncycletime). This value may exceed the patterncycletime during a coord cycle in which the system reference point has changed. 102 ATCLink Operating Manual

113 Coordination Object Module System Pattern Control This object is used to establish the Called System Pattern / Mode for the device. The possible values are: Table 25 System Pattern Control options Value Description 0 Standby - the system relinquishes control of the device Pattern - these values indicate the system commanded pattern 254 Free - this value indicates a call for Free 255 Flash - this value indicates a call for Automatic Flash If an unsupported / invalid pattern is called, Free shall be the operational mode. The value of this object is ignored in BACKUP mode. A write to this object shall reset the BACKUP timer to ZERO. USTC Coord Correction Mode This object is used to define the USTC Proprietary Coordination Correction Mode for this device. The possible modes are: Toronto (0): coordinator establishes a new offset using the Toronto offset Correction strategy. Other (1): the coordinator establishes a new offset based on the value of coordcorrectionmode. Pattern Table Parameters Max Patterns The maximum number of Patterns this Actuated Controller Unit supports. This object indicates how many rows are in the patterntable object (254 and 255 are defined as non-pattern status for Free and Flash). Pattern Table Type This object provides information about any special organizational structure required for the pattern table. The defined structures are as follows: Table 26 Pattern Table Types Structure other patterns offset3 offset5 Description The pattern table setup is not described in this standard, refer to device manual. Each row of the pattern table represents a unique pattern and has no dependencies on other rows. The pattern table is organized into plans which have three offsets. Each plan uses three consecutive rows. Only the offsettime value may vary between each of the three rows. Plan 1 is contained in rows 1, 2 and 3, Plan 2 is contained in rows 4, 5 and 6, Plan 3 is in rows 7, 8 and 9, etc. The pattern table is organized into plans which have five offsets. Each plan occupies five consecutive rows. Only the offsettime value may vary between each of the rows. Plan 1 is contained in rows 1, 2, 3, 4 and 5, Plan 2 is contained in rows, 6,7, 8, 9 and 10, Plan 3 is contained in rows 11, 12, 13, 14 and 15, etc.." ATCLink Operating Manual 103

114 Chapter 5 Editing a Controller Database REFERENCE: NEMA TS 2 Clause and Pattern Cycle Time The patterncycletime object specifies the length of the pattern cycle in seconds (NEMA TS 2 range: ). A pattern cycle time less than adequate to service the minimum requirements of all phases shall result in Free mode. The minimum requirements of a phase with a not-actuated ped include Minimum Green, Walk, Pedestrian Clear, Yellow Clearance, and Red Clearance; the minimum requirements of a phase with an actuated pedestrian include Minimum Green, Yellow Clearance, and Red Clearance. If the pattern cycle time is zero and the associated split table (if any) contains values greater than zero, then the CU shall utilize the split time values as maximum values for each phase. REFERENCE: NEMA TS 2 Clause Pattern Offset Time The patternoffsettime defines by how many seconds (NEMA TS 2 range: 0-254) the local time zero shall lag the system time zero (synchronization pulse) for this pattern. An offset value equal to or greater than the cycle time shall result in Free being the operational mode. While this condition exists, the Local Free bit of unitalarmstatus and the LocalOverride bit of shortalarmstatus shall be set to one (1). REFERENCE: NEMA TS 2 Clause Pattern Split Number This object is used to locate information in the splittable to use for this pattern. This value shall not exceed the maxsplits object value. Pattern Sequence Number This object is used to locate information in the sequence Table to use with this pattern. This value shall not exceed the maxsequences object value. USTC Coord Offset Correction Threshold This object is applicable only if ustccoordcorrectionmode is set to Toronto and coordcorrectionmode is set to other. It defines a percentage of the current cycle length that determines if time should be added or subtracted to splits when establishing a new offset based on how late or early the coordinated phase begins. Valid input is an integer (1-99). Split Tables Parameters Split Table The maximum number of Split Plans this Actuated Controller Unit supports. This object indicates how many Split plans are in the splittable object (1-16). Split Time The time in seconds the splitphase is allowed to receive (i.e. before a Force Off is applied) when constant demands exist on all phases. In floating coordforcemode, this is always the maximum time a non-coordinated phase is allowed to receive. In fixed coordforcemode, the actual allowed time may be longer if a previous phase gapped out. The splittime includes all phase clearance times for the associated phase. The split time shall be longer than the sum of the phase minimum service requirements for the phase. When the time is NOT adequate to service the minimum service requirements of the phase, Free Mode shall be the result. The minimum requirements of a phase with a notactuated ped include Minimum Green, Walk, Pedestrian Clear, Yellow Clearance, and Red Clearance; the minimum requirements of a phase with an actuated pedestrian include Minimum Green, Yellow Clearance, and Red Clearance. If the cycletime entry of the associated patterntable entry is zero (i.e. the device is in Free Mode), then the value of this object shall be applied, if non-zero, as a maximum time for the associated phase. 104 ATCLink Operating Manual

115 Preempt Object Module If the critical path through the phase diagram is less than the cycletime entry of the associated patterntable entry, all extra time is allotted to the coordination phase in each ring. If the critical path through the phase diagram is greater than the cycletime entry of the associated patterntable entry (and the cycletime is not zero) the device shall operate in the Free Mode. While the Free Mode condition exists, the Local Override bit of shortalarm shall be set to one (1). REFERENCE: NEMA TS 2 Clause Split Mode This object defines operational characteristics of the phase. The following options are available: Table 27 Split Mode options Mode other none minimumvehiclerecall maximumvehiclerecall pedestrianrecall maximumvehicleandpedestrian Recall phaseomitted Description the operation is not specified in this standard no split mode control. this phase operates with a minimum vehicle recall. this phase operates with a maximum vehicle recall. this phase operates with a pedestrian recall. this phase operates with a maximum vehicle & pedestrian recall. this phase is omitted. Split Coord Phase To select the associated phase as a coordinated phase this object shall be set to TRUE (non zero). Offset Correction Max Extend (0-255) The maximum amount of time that a split may extend when ustccoordcorrectionmode is set to Toronto and the offset is being restored. Offset Correction Max Reduce (0-255) The maximum amount of time that a split may reduce when ustccoordcorrectionmode is set to Toronto and the offset is being restored. tsp Max Reduction (0-255) This object represents the maximum number of seconds that the split of a phase can be reduced by during a priority strategy. This effective value may be reduced by the CO based on the operating phase minimum service requirements. NOTE - The definition of a phases minimum service is dependent on whether it is actuated or non-actuated, whether the ped clear terminates before the yellow or not, whether variable initial is active or not, whether it is a coord phase or not, and whether it is in a single or multi-ring configuration. tsp Max Extension (0-255) This object represents the maximum number of seconds that the split of a phase can be extended during a priority strategy. The effective value may be modified by the CO based on time gained from one cycle of reductions to the respective non-priority phases.

All active phases not listed in the preemptdwellphase shall flash Red. If any conflicting phase numbers are listed in the preemptdwellphase then all active phases shall flash Red. This control is optional. 2 Preempt Override preemptnumber provide a means to define whether this preempt shall NOT override the next higher numbered Preempt. When set (1) this preempt shall not override the next higher numbered preempt. This parameter shall be ignored when preemptnumber equals maxpreempts. 1 Preempt Override Flash - provide a means to define whether this preempt shall NOT override Automatic Flash. When set (1) this preempt shall not override Automatic Flash. 0 Non-Locking Memory - provide a means to enable an operation which does not require detector memory. When set (1) a preempt sequence shall not occur if the preempt input terminates prior to expiration of the preemptdelay time.

Any value that is not a higher priority preempt or a valid preempt shall be ignored. The value shall not exceed the maxpreempts object value." Delay Preempt Delay Time in seconds ( sec). This value determines the time the preempt input shall be active prior to initiating any preempt sequence. A non-locking preempt input which is removed prior to the completion of this time shall not cause a preempt sequence to occur. Minimum Duration Preempt Minimum Duration Time in seconds ( ). This value determines the minimum time during which the preempt is active. Duration begins timing at the end of Preempt Delay (if non zero) and will prevent an exit from the Dwell state until this time has elapsed. Minimum Green Preempt Minimum Green Time in seconds (0-255 sec). A preempt initiated transition shall not cause the termination of an existing Green prior to its display for lesser of the phase's Minimum Green time or this period. Minimum Walk Preempt Minimum Walk Time in seconds (0-255 sec). A preempt initiated transition shall not cause the termination of an existing Walk prior to its display for the lesser of the phase's Minimum Walk time or this period. Enter Ped Clear Enter Ped ClearTime in seconds (0-255 sec). This parameter controls the ped clear timing for a normal Walk signal terminated by a preempt initiated transition. A preempt initiated transition shall not cause the termination of a Pedestrian Clearance prior to its display for the lesser of the phase's Pedestrian Clearance time or this period.

118 Chapter 5 Editing a Controller Database Track Green Track Clear Green Time in seconds (0-255 sec). This parameter controls the green timing for the track clearance movement. The phase(s) active during the Track Green interval are enabled in preempttrackphase object. Dwell Green Minimum Dwell Time in seconds (1-255 sec). This parameter controls the minimum timing for the dwell movement. The phase(s) active during the Dwell interval are enabled in preemptdwellphase object. The Dwell interval shall not terminate prior to the completion of Preempt Duration Time, Preempt Dwell Time, & the call is no longer present. Maximum Presence Preempt Maximum Presence time in seconds ( sec). This value determines the maximum time which a preempt call may remain active and be considered valid. When the preempt call has been active for this time period, the CU shall return to normal operation. This preempt call shall be considered invalid until such time as a change in state occurs (no longer active). When set to zero the preempt maximum presence time is disabled.

131 Overlap Object Module Bit 0 = Overlap number = (overlapstatusgroupnumber * 8) 7 Pedestrian Table Parameters The following parameters can be set for each of the eight pedestrian overlaps. Included Phases Each octet is a phase number that is an included phase for the ped overlap. The phase number value can not exceed the maxphases object value. The ped overlap transfers from don't walk to walk if a modifier phase included phase is green. The ped overlap transfers from walk to ped clearance when the programmed walk time expires. The ped overlap transfers from ped clearance to don't walk when the programmed ped clearance time expires. If a ped overlap is active, an included phase may terminate only if the next phase(s) for service is an included phase. Modifier Phases Each octet is a phase number that is a modifier phase for the ped overlap. The phase number value may not exceed the maxphases object value. The modifier phase determines which phases cause a ped overlap to transfer from don't walk to walk. The modifier phase must also be an included phase. A modifier phase that is not an included phase is ignored. Walk Time The walk time in seconds (1-255 sec.) for the pedestrian overlap.

133 Security Object Module SECURITY OBJECT MODULE This module is where SNMP security values can be viewed and edited, including community names and access masks. There are two methods available to open this module: By going to the Menu menu and choosing Security Object Or by selecting the Security Object button ( ) on the controller toolbar Figure 53 Security Object Module window The Security object parameters are all configured in a single window within this module, allowing for the programming of up to 15 community user names and their access masks. Community Name Admin This object is the community name that must be used to specifically gain access to information under the security node. A message with this value in the community name field of an SNMP message has user read-write access to the security node objects and all other objects implemented in the device. The syntax is defined as an OCTET STRING and therefore any character can have a value of communitynameuser This object defines a community name value that a security administrator can assign user read-write access to information (other than security) in a device. A message with this value in the community name field of an SNMP message has user access rights as defined in the communitynameaccessmask. The syntax is defined as an OCTET STRING and therefore any character can have a value of communitynameaccessmask This object defines a 32 bit mask that can be used to associate 'write access' with a community name. A value of 0x grants the community name user read-only access and overrides any individual object's read-write access clause. A value of OxFFFFFFFF grants the community name user read-write access and an individual object's read-write access clause applies. Values other than 0x and 0xFFFFFFFF are implementation specific and may limit viewing and/or accessing the information in a device. REPORT VIEW MODULE Somewhat of a misnomer, the Report View Module is actually where the user can view and edit the parameters for event logging and event classes within the controller. ATCLink Operating Manual 123

134 Chapter 5 Editing a Controller Database The Report View Module can be opened by clicking on the Report View button on the NEMA toolbar. Figure 54 Global Event Log Report Window (Report View Module) The settings used by the controller to determine what events generate entries in its event log are set on three tabs in this module: the Event Log Config Table, the Event Log Table, and the Event Class Table. Event Log Config Table Parameters Max Event Log Configs The number of rows that exist in the static eventlogconfig table for this device. Event Config Class This object contains the class value to assign to the event associated with this row in the event configuration table. This value is used in the event log table to organize various events defined in this table into logical groupings. 124 ATCLink Operating Manual

135 Report View Module Event Config Mode This object specifies the mode of operation for this event. All checks and entries to the table must occur within one second of the condition becoming true. The modes are defined as follows: Table 34 Event Config modes Mode other onchange greaterthanvalue smallerthanvalue hysteresisbound periodic andwithvalue Description create a log entry through an alternate mechanism. create a log entry when value referenced by the eventtypeoid changes. create a log entry when the object value becomes greater than the value referenced to by the eventcomparevalue object, if this value is exceeded for the amount of time specified in the eventconfigcomparevalue2 object (in tenth of seconds) and this value is greater than zero (0). A value of zero (0) for eventconfigcomparevalue2 indicates immediate logging. create a log entry when the object value becomes less than the value referenced to by the eventcomparevalue object, if this value is exceeded for the amount of time specified in the eventconfigcomparevalue2 object (in tenth of seconds) and this value is greater than zero (0). A value of zero (0) for eventconfigcomparevalue2 indicates immediate logging. creates a log entry when the object value becomes either less than the lower bound value or greater than the upper bound value. The lowerbound value is the lower value of the eventconfigcomparevalue- and the eventconfigcomparevalue2- objects, the upper bound is the other value. create a log entry every x seconds, where x is defined by the value stored in eventconfigcomparevalue. The values stored in eventconfigcomparevalue2 and eventconfigcompareoid are ignored in this mode." Is the operator for combining eventconfigcomparevalue and eventconfigcomparevalue 2. Event Config Compare Value This object contains the comparison value to use with eventconfigmode values (greaterthanvalue, smallerthanvalue, hysteresisbound ). No value within this object is necessary when the eventconfigmode-object has the value onchange (2). Event Config Compare Value 2 If the eventconfigmode is set to hysteresisbound, this object specifies the second comparison value for the hysteresis. If the eventconfigmode is set to greaterthanvalue or smallerthanvalue, this object specifies the time (in tenths of seconds) for which the comparison must be true prior to the event condition becoming true. If the eventconfigmode is set to onchange or periodic, the value of this object shall be ignored. Event Config Compare OID This object contains the object identifier which references the value against which the comparison is made. If the eventconfigmode is set to periodic, the value of this object shall be ignored. ATCLink Operating Manual 125

136 Chapter 5 Editing a Controller Database Event Config Log OID This object contains the object identifier which indicates what value to log when a condition or event occurs (e.g., log the phase display when the watchdog alarm status changes). Event Config Action This value of this object indicates the action that will take place when the event described in this row of the event configuration table occurs. Table 35 Event Config Action options Value other disabled log Description an alternate form of logging will occur, which does not use this mechanism. no entry will be recorded due to this event. an entry will be recorded in the event log table when this event occurs. Event Log Table Parameters Max Event Log Size The maximum, fixed number of rows that can be utilized within the Event Log Table. The following three parameters can be defined for each of up to 255 Event IDs in each of seven (7) event log classes. Event Log ID This object contains the event configuration ID (from the eventlogconfigtable) that caused this table entry. It indicates the row in the eventlogconfig table responsible for this event entry. If this object is set to zero (0) then the associated row (in the eventlogtable) is cleared and the following rows shall be renumbered to maintain a sequential eventnumber sequence. Event Log Time The time that the event occurred in seconds since the epoch of 00:00:00 (midnight) January 1, 1970 per the device's globaltime object. If the device does not have valid date and time information, then this shall be the time in seconds since the device powered up. Event Log Value The value of this object is set to the value referenced by the eventconfiglogoid of the associated eventlogid when the event was logged. Its length is variable. Event Class Table Parameters Max Event Classes This object defines the maximum, fixed number of rows in the eventclasstable that this device supports. This places an upper limit on the number of classes that may be defined for events in this device. The following four parameters can be defined for each of the seven available Event Classes: Event Class Limit This object specifies the maximum number of events of the associated class to store in the log. Once the limit is reached, the oldest entry of the matching class will be overwritten by any new entry of the same class. If the value of this object is set to a number smaller than the current number of rows within this class in the eventlogtable, then the oldest entries shall be lost/deleted. 126 ATCLink Operating Manual

137 Report View Module Event Class Clear Time This object is used to clear multiple event log entries from the event log table.

138 Chapter 5 Editing a Controller Database PRETIMED OBJECT MODULE If the controller will run in the more basic pre-timed mode, this module is where the timings, cycle length, split times, and preemption settings are viewed and edited. The Pretimed Object module can be launched in a couple of ways: By going to the Menu menu and choosing Pretimed Object Or by selecting the Pretimed Object button ( ) on the controller toolbar Figure 55 Pretimed Object Module window The parameters in the PreTimed Object module are distributed across four tabs: Pretimed timing plan, Pretimed signal plan, Preempt, and Preempt & Interval Skipping. Pretimed Timing Plan Parameters Timing Plan The timing plan number. Cycle Length pretimedtimingcyclelength. This value is automatically calculated whenever the times below on the table are changed and the enter key is pressed, but only for times set to type tenth or sec. Offset The meaning of the value of this object is determined by the pretimedtimingoffsettype object: Table 36 Offset meaning by offset type Type other seconds percent Meaning the meaning is not specified seconds in 1.0 second increments 0-99 percent of cycle length in 1% increments 128 ATCLink Operating Manual

139 Pretimed Object Module Intervals Used The number of intervals used in this timing plan. The value of this object shall not exceed the maxpretimedintervals object value. This object determines the maximum used value of the pretimedtimingsplitnumber object in the pretimedtimingsplittable. For each of the up-to 24 splits that can be programmed, the following two values can be defined: type The value of this object determines the meaning of the pretimedtimingsplittime object. time The meaning of the value of this object is determined by the pretimedtimingsplittype object: Table 37 Meaning of time parameter Split Type other tenths seconds percent Meaning the meaning is not specified seconds in 0.1 second increments seconds in 1.0 second increments 0-99 percent of cycle length in 1% increments TSP Max Reduction Time This object represents the maximum number of seconds that the split of a phase can be reduced by during a priority strategy. This effective value may be reduced by the CO based on the operating phase minimum service requirements. Note The definition of a phases minimum service is dependent on whether it is actuated or non-actuated, whether the ped clear terminates before the yellow or not, whether variable initial is active or not, whether it is a coord phase or not, and whether it is in a single or multi-ring configuration. Tsp Max Extension Time This object represents the maximum number of seconds that the split of a phase can be extended during a priority strategy. The effective value may be modified by the CO based on time gained from one cycle of reductions to the respective non-priority phases. Pretimed Signal Plan Parameters Signal Plan Signal plan number Timing plan transfer interval The interval end at which a timing plan transfer out of this plan may occur. Signal plan transfer interval Object Name : pretimedtimingsplittype_1_13, Object OID : Attributes : READ/WRITE Flash entry interval The Automatic Flash Entry point shall be the end of this interval. The value of this object will not exceed the value of the maxpretimedintervals object. ATCLink Operating Manual 129

140 Chapter 5 Editing a Controller Database Flash exit interval The Automatic Flash Exit point shall be the beginning of this interval. The value of this object will not exceed the value of the maxpretimedintervals object. Config Jumper Can be set to either Top or Bottom values, based on the position of the config jumper on the controller. The default setting is Top. (This only applies to the ASTC-6 cabinet with respect to the CMU monitoring the yellows of load switches 5 and 6.) View the configuration jumpers in the cabinet and make sure that this setting matches the cabinet setting. Top refers to both jumper settings placed at 13 and 14. Bottom refers to both jumper settings placed at 15 and 16. View Program Card This control, when pressed, generates a display of the CMU s program card and presents it to the user in the default web browser. Compare to CMU This control can only be used when a live connection is available to a controller, and the controller must have an attached CMU configured. For each of the up to 24 intervals that can be defined, these values may be set: Minimum The minimum time for this interval in this signal plan, 0 to 25.5 seconds in 0.1 second increments. police button stop here TRUE (1) if interval is variable for offset correction, force off, and MCE operation. FALSE (0) if interval is fixed. actuated TRUE (1) if this interval is actuated, FALSE (0) if not. recall TRUE (1) to apply a demand for service for this interval if it is actuated and not active, FALSE (0) if not. do not lock here TRUE (1) if vehicle detector calls to this interval are locking, FALSE (0) if not. Locking means the demand for service remains until the interval is serviced, even if the actual detector call is removed. Pedestrian calls are always locking. detectors Each octet is a Detector (number). Activity on any of these detectors shall cause this interval to be serviced. The detector number value shall not exceed the maxvehicledetectors object value. ped detectors Each octet is a Pedestrian Detector (number). Activity on any of these pedestrian detectors shall cause this interval to be serviced. The pedestrian detector number value shall not exceed the maxpedestriandetectors object value.

If this control is false, the CU shall display the intervals once and wait in the last interval until dwell ends. 1 pretimedpreempt Override Flash - provide a means to define whether this pretimedpreempt shall NOT override Automatic Flash. When set (1) this pretimedpreempt shall not override Automatic Flash. 0 Non-Locking Memory - provide a means to enable an operation which does not require detector memory. When set (1) a pretimedpreempt sequence shall not occur if the pretimedpreempt input terminates prior to expiration of the pretimedpreemptdelay time. Delay Preempt Delay Time in seconds ( sec). This value determines the time the preempt input shall be active prior to initiating any preempt sequence. A non-locking preempt input which is removed prior to the completion of this time shall not cause a preempt sequence to occur. Minimum Duration Preempt Minimum Duration Time in seconds ( ). This value determines the minimum time during which the preempt is active. Duration begins timing at the end of Preempt Delay (if non zero) and will prevent an exit from the Dwell state until this time has elapsed. Maximum Presence Preempt Maximum Presence time in seconds ( sec). This value determines the maximum time which a preempt call may remain active and be considered valid. When the preempt call has been active for this time period, the CU shall return to normal operation. This preempt call shall be considered invalid until such time as a change in state occurs (no longer active). When set to zero the preempt maximum presence time is disabled. For the 18 available preemption intervals (6 track clear, 6 dwell, and 6 exit), the following values may be set: Time The length of time available in each interval. Channel 1 to Channel 6Amber The signal output for each channel within each interval. This can be set to one of the following values for each channel: None, Green, Yellow, Red, Walk, FDW, or Don t Walk. Preempt & Interval Skipping Parameters For the eight available output channels ( Channel1 to Channel 6 Amber ), the following additional preemption parameters may be set: Ped Clearance Preempt and Interval Skipping Pedestrian Clearance Parameter in seconds.

A value of zero (0) means to disable TSP during this TOD scheduled period of time. The value of this object must be less than or equal to tspmaxactionplans. DST (Daylight Savings Times) Parameters DST is where the controller s Daylight Savings Time beginning and ending setting can be defined and edited. Begin Month The month during which Daylight Saving Time begins. An entry of 'absolute' means that dstbeginsecondstotransition defines an absolute time to begin DST relative to midnight January 1, In this case, the value of dstendmonth object is irrelevant and the dstendsecondstotransition object defines an absolute time to end DST relative to midnight January 1, An entry of 'other' shall mean that DST adjustments are by a means other than this object. If this object is SET to 'other', the agent shall return a generr. If the value of this object is disabled (14) or other (15), then the values in the remaining objects in the current row of the dsttable are irrelevant and therefore ignored by the device. An entry of 'disabled' shall mean that DST is controlled by this object and is disabled. Devices which support both this object and the older globaldaylightsaving object shall follow the following rules. a.) If globaldaylightsaving is SET to 'other', the device will return a generr. b.) If globaldaylightsaving is SET to any other value, the device will automatically transition the value of dstbeginmonth to 'other'. c.) If dstbeginmonth is SET to 'other', the device will return a generr. d.) If dstbeginmonth is SET to any other value, the device will automatically transition the value of globaldaylightsaving to 'other'. Devices which support this object and another mechanism to control daylight savings that is not defined by this standard; follow the following rules: a.) If dstbeginmonth is SET to 'other', the device will return a generr. b.) If globaldaylightsaving or dstbeginmonth is SET to any value except 'other' the device will prevent the other mechanism from affecting DST adjustments. c.) If the other mechanism is enabled in any way, the device will transition the values of globaldaylightsaving and dstbeginmonth to 'other'. ATCLink Operating Manual 137

159 Configuration Object Module CONFIGURATION OBJECT MODULE This module is where the current make, model, and version information can be viewed for the controller hardware, software, OS, and database, as well as other modular pieces of code within the unit. The Configuration Object module can be launched in a couple of ways: By going to the Menu menu and choosing Configuration Object Or by selecting the Configuration Object button ( ) on the controller toolbar Figure 58 Configuration Object Module window All of the data in this object is visible in a single window in this module. ID Parameter Specifies a relatively unique ID for all user-changeable parameters of the particular device-type currently implemented in the device. Often this ID is calculated using a CRC algorithm. Each component whose configuration is being tracked in the database includes the following five pieces of information: Device Node This object contains the device node number of the device-type. Make This object specifies the manufacturer of the associated module. A null-string shall be transmitted if this object has no entry. Model This object specifies the model number (hardware) or firmware reference (software) of the associated module. A null-string shall be transmitted if this object has no entry. Version This object specifies the version of the associated module. A null-string shall be transmitted if this object has no entry. Type This object specifies if the associated module is a hardware or software module. ATCLink Operating Manual 149

160 Chapter 5 Editing a Controller Database MESSAGE LOG MODULE Unlike many of the other modules presented here, the Message Log Module is not an editable database. This module provides a tool that allows the user to view, print, and save Controller Unit message and error message logs as.txt files. The report shown below in Figure 59 is representative of a typical log that would be generated by this message log function. This function supports all of the controller messages and is only available when you have a live connection to a controller. The Message Log Module can be opened by going to the Menu menu and choosing Message Log. Figure 59 Message Log Module Window The module has its own toolbar, with the following functions: Figure 60 Message LogModule toolbar The message log window, Figure 60 above, shows the message log received from the controller. The function to receive data is triggered by using the Read Data from the ASTC button in the Message Log window toolbar (shown at right). 150 ATCLink Operating Manual

161 Message Log Module Figure 61 Saving a Message Log to a file Saving a Message Log File To write a message log to a file (on your file system, or a USB memory device, or an external hard drive, or whatever), follow these steps: 1. Open the Message Log module 2. Select the Read Data from the ASTC button in the Message Log window toolbar to generate the report. 3. Check the Save button in the Message Log window toolbar. 4. This opens the Save As box as shown in Figure 61. Select the storage location for the log. 5. Select a destination in the Save In box. 6. Enter the File Name the log will be save as. 7. Click the Save button to complete the save. ATCLink Operating Manual 151

162 Chapter 5 Editing a Controller Database UP/DOWNLOAD BLOCKS MODULE The Up/Download Blocks module is not like many of the other modules described here. It is not used to view and edit database parameters, but rather this module allows a user to define how a simple database transfer function works. The normal transfer of data to and from a controller uses the full SNMP communications protocol. This module, on the other hand, works with the simple upload and download capability that was originally implemented solely for USB memory device transfers to and from controllers, so it is labeled with the USB icon, but the module does more than that in the current release of ATCLink. The Up/Download Blocks module can be launched in a couple of ways: By going to the Menu menu and choosing Updownload blocks Or by selecting the UpDownload Blocks button ( ) on the controller toolbar Figure 62 Up/Download Block module The single pane in this module provides a set of check boxes that determine which data is included in an upload or download request from this module. These are shown in the blue area of the table. These are grouped into pretimed DB Download and NEMA DB Download data objects. The exact function of this module depends on a couple factors. If a controller is connected live to ATCLink, it can be used to do lite uploads and downloads directly to the controller. Otherwise, it can be used to save a compressed database file out to your file system (including onto a USB memory device, if you choose.) Note The ATC family of controllers has been designed to automatically load this file into memory when the USB device is plugged into their front panels. But this function will only operate correctly if the file has been stored in the correct compressed file format (i.e. a.blk file) AND the USB device has been properly formatted with the correct signature file and directory structure. Otherwise the controller will not recognize the database stored on the USB device. The functions to send or receive data are triggered by using the Send Selected Data to ASTC and Read Selected Data from the ASTC buttons in the Send Read 152 ATCLink Operating Manual

163 Up/Download Blocks Module ATCLink Main window toolbar. These buttons only work in this way while this module is open. Write to USB File If the Write to USB file checkbox is checked, the module will save the database by compressing it into a.blk file and prompting the user to save it to your PC s file system (See Figure 63). If the Write to USB file box is not checked, pressing the ( ) buttons instead writes and reads directly to or from the controller. See the Create USB Signature File and Directory Structure topic below for information about creating a signature file. Pretimed DB Download If this box is checked, it selects only the blocks in the NEMA and Pretimed area above on this window that are required for Pretimed controller operation. Toggles with the NEMA DB Download button. NEMA DB Download If this box is checked, it selects all of the blocks in both the NEMA and the Pretimed list in the window above. Toggles with the Pretimed DB Download button. The module also functions as a debugging tool when problems are encountered sending a database to a controller, but only when a controller is connected directly. You can start the process by modifying a local database. Since this module works with lite downloads, de-select Write to USB file, send the file to the controller, and then monitor the communications Status window at the bottom to see exactly which data object is faulty. (Otherwise, if the database is loaded onto the controller via the USB thumb drive, the controller will not be able to tell you what portion of the database is causing an error.) Create USB Signature File and Directory Structure To enable a USB memory device to function as a database or firmware source for an IQ ATC controller, it must first be configured with a signature file and the appropriate directory structure. See the Formatting a USB Device for use as a Data Source section, on page 65 for instructions for creating a signature file. Saving a Database File The USB memory device must first be configured with a signature file and the appropriate directory structure before it can function as a database or firmware source for an IQ ATC controller. See the To write a compressed version of the controller s database to a file (on your file system, or a USB thumb drive, or an external hard drive, or whatever), follow these steps: 1. Open the Up/Download Blocks module 2. Select the Blocks (or groups of blocks) you wish to update on the controller. 3. Check the Write to USB file checkbox. 4. Click on the Send selected data to the ASTC button on the Main Window s toolbar. (These buttons have this unique function only when the Up/Download module is open and the Write to USB file checkbox has been checked.) Send ATCLink Operating Manual 153

164 Chapter 5 Editing a Controller Database 5. This opens the USB Export dialog box shown in Figure 63. Select the storage location for the database file by clicking on the Select Directory button and choosing the directory. 6. Back in the USB Export dialog box, select which database you wish to send to the memory location, then press OK to proceed. Figure 63 Saving the database to a compressed USB file This will save the information to the selected memory location. Note that you can select multiple controller databases, in which case they will each be saved to a separate compressed.blk file in the selected memory location. 154 ATCLink Operating Manual

165 Intersection Status Module INTERSECTION STATUS MODULE The Intersection Status module can be used to poll and display the live operation of a controller within ATCLink. It is only available when you have a live connection with a controller. The Intersection Status module can be launched in a couple of ways: By going to the Menu menu and choosing Intersection Status Display Or by selecting the Intersection Status button ( ) on the controller toolbar Figure 64 Intersection Status Module This module provides a fairly comprehensive view of the operational parameters of your ATC family traffic controller, including the current states of all of the vehicle and ped phase signals, the coordination or pattern status, preemption status, detector input values, cabinet states, channel status, the state of overlap phases, and any phase modifiers such as vehicle and pedestrian calls, omits, holds, and force offs that are active. Note To see actual status updates within this window, you must Start automatic polling. This can be done using the Start/Stop Automatic Polling button in the Main Window toolbar, as shown at the right. When polling is active, the polling status indicator in the ATCLink status bar turns green. And remember, to close this module, you must first turn off polling by again clicking on the Start/Stop Automatic Polling button in the Main Window toolbar. ATCLink Operating Manual 155

166 Chapter 5 Editing a Controller Database INPUT/OUTPUT MAPPING MODULE In a TS-2/Type 1 cabinet, the controller interacts with the cabinet through BIU (Bus Interface Unit) modules. The Input/Output Mapping (or I/O Mapping) module of ATCLink is used to view and edit the mapping values used by the controller to send logical inputs and outputs to the BIU s physical input and output pins. The I/O Mapping module can be opened in a couple of ways: By going to the Menu menu and choosing I/O Map Or by selecting the Input/Output mapping button ( ) on the controller toolbar Figure 65 Input/Output Mapping Module window The parameters in the Input/Output Mapping module are stored on three tabs: the TS2Port1 tab, which includes BIU comms parameters, the TF BIUs tab, which provides the mapping table for the cabinet s terminals and facilities, and the DET BIU s tab, which provides the mapping table for the cabinet s detectors. TS2Port1 Parameters ASTC Cab Type Select which type of controller cabinet this database is intended for. This can be (1) an ASTC Type 6, (2) an ASTC Type 12, (3) an ASTC Type 6 Extended, (4) an ASTC Type 12 extended cabinet, or (0) other. The following parameters can be set for each of the four TF BIUs, and each of the four Detector BIUs. Port1 Device Present Indicates whether the specified device is present on Port 1. Port 1 Status Indicates the status of the selected BIU. Port 1 Fault Frame Indicates the frame number that caused the most recent fault ATCLink Operating Manual

167 TF BIU Parameters Input/Output Mapping Module When you first open this tab for the controller, you will be asked if you would like to load the default BIU mapping values for your type of cabinet. Map Command You can configure two mappings in this environment, a (0) default I/O mapping, or a (1) alternative I/O mapping. Function Name In each output box for each of the BIUs, you can select what the internal channel function is. Flash Rate Output Mask A flash rate may be selected for load switch green output drivers. This is achieved by using the top 4 bits (0xF000) of the 16 bit value. There are 3 flash rates: 0x1000 = Flash at a 250ms on/off rate. 0x2000 = Flash at a 500ms on/off rate. 0x4000 = Flash at a 1000ms on/of rate. The lower 12 bits represent the function value as described above. To set the Flash Rate Output Mask value: Click on the cell in the F column to the left of the TF BIU Output to open the Flash Rate window. Check the box to the left of the desired flash rate. Click OK to close the Flash Rate window Figure 66 Flash Rate Output Mask DET BIU Parameters The columns on this page are available only when one or more of the DET BIU N item on the TS2Port1 tab are marked as Present. Each cell shows what function is assigned to each of the BIUs pins. ATCLink Operating Manual 157

168 Chapter 5 Editing a Controller Database UPS INTERFACE MODULE This module allows the user to view and edit the parameters that a controller uses to interact with a cabinet UPS Battery backup system, if one is installed. The UPS Interface module can be opened in a couple of ways: By going to the Menu menu and choosing UPS Or by selecting the UPS interface button ( ) on the controller toolbar Figure 67 UPS Interface Module window The UPS interface parameters are divided across two tabs: Control/Status and Event Log.

Otherwise the serial port number on device. Retries The maximum number of times an agent will attempt to retransmit a trap before transitioning to the error state. Note: a value of one will indicate that the agent will attempt a maximum of two transmissions. Repeat Int The minimum number of seconds to wait before retransmitting a trap that has not been acknowledged by a reset. The value of zero(0) shall allow immediate trap retransmission. Delta A number of seconds to be added to the total timeout for the next trap retransmission. QDepth The maximum number of traps that can be queued for the management station. Setting value of zero will flash and disable the queue, and prevent the manager from receiving any traps. Link State This object contains the current link state of the manager registered in this row. The states are defined as follows: ready (2) - any trap can be sent to the manager (initial condition after power-on); if a NORMAL trap appears in the queue the agent sends the trap message to the manager, starts timer and internal retry counter, and sets the state to pending pending (3) - waiting for the manager to acknowledge the last NORMAL trap (by changing the state to ready); most of the free traps (depends of the mode) can be transmitted to the manager; if after all retries and timeouts the management station did not acknowledge a normal trap message the agent sets the state to error; set by the agent only error (4) - the agent assumes that the link is down (for any reason) and only 'forced' traps can be sent to the manager; set by the agent only Anti SRate The maximum number of traps that can be generated on a specific trap channel in one minute. The agent shall reset the anti streaming counter at the start of each minute. If the anti-streaming rate is reached the agent shall set the 'Trap channel anti-streaming mode activated' bit in the trapmgmterrstat, send the current trap and cease sending any additional traps on this trap channel until the start of the next minute.

Trap Table Parameters Manager Name This object provides the index into the ustctrapmgmttable. Enable Setting this object to 1 will enable a manager to receive the trap of eventconfigid event if the eventconfigid points to the valid entry in eventlogconfigtable and usttrapmgmtmanagername points to the valid entry in ustctrapmgmttable (the management station is registered as a 'trapable' one). Zero will disable eventconfigid trap for the ustctrapmgmtmanagername station. Mode It defines trap operational mode: 0 - trap disabled, 1 - forced: free, sent regardless of the link state 2 - normal_noq: normal, sent if link ready, otherwise dropped 3 normal: normal, sent if link ready, otherwise queued 4 - free_noq: free, sent if link ready or pending, otherwise dropped 5 - free: free, sent if link ready or pending, otherwise queued 6 - normal_aggr : normal, added to the normaltrapchain; when its aggregation time is 0 or the aggregation time expired the trap message containing trapchain data is immediately sent to the management station if the link is READY; the chain cannot be transmitted to the manager while the link is in PENDING state but it will grow accepting new traps and if the chain size exceeds 170 ATCLink Operating Manual

181 Trap Management Module ustctrapmaxaggregationsize and the link is still in PENDING (or in ERROR) the whole chain is dropped 7 - free_aggr: free, added to the freetrapchain; when its aggregation time is 0 or the aggregation time expired the trap message containing trapchain data is immediately sent to the management station if the link is NOT in ERROR, otherwise it will grow accepting new traps and if the chain size exceeds ustctrapmaxaggregationsize and the link is still in ERROR the whole chain is dropped 8 - free_car: free, added to the traptrain 9 - free_eng: free, added to the traptrain and the trap message containing traptrain data is immediately sent to the management station if the link is NOT in ERROR, otherwise it is dropped Aggregation Time It defines the maximum time in tenth of second the trap can wait for a transfer to the manager. The value of zero forces immediate trapchain transmission. Count The number of traps sent by the agent to the management station since last reboot. Watch Object Table Parameters Status The value of this object indicates the current status of this row in the table. Block This object contains the block number to assign to the watch object associated with this row in the watch object definition table. This value shall not exceed the value indicated by the maxwatchblocks object. O.I.D This object contains the object identifier of the object to watch. The following objects shall NOT be assigned to any watchoid: All objects under the security node (Annex B) {NEMA transportation devices global security} All objects under the dynobjmgmt node (Annex A) {NEMA transportation protocols dynobjmgmt} ATCLink Operating Manual 171

182 Chapter 5 Editing a Controller Database All objects under the chap node (Annex B of NTCIP 2301) {NEMA transportation protocols layers chap} Any objects so identified by various device standards Any objects whose SYNTAX does NOT resolve to a ranged or un-ranged INTEGER. Any other report object or watch object Any objects that the agent/device does not support. An agent should return a bad Value error if it receives a SET command for any of the above. Watch Block Table Parameters Watch Blocks are OER encoded configurable read only blocks intended to be utilized for device status monitoring in the eventconfigcompareoid, in the eventconfigtable. The intent is to be able to configure events to monitor a collection of NTCIP objects at the same time, and trigger the logging and/or transmission of a trap message. Note Note that when a watch block is used for the eventconfigcompoid, the eventconfigmode object is restricted to onchange (2). Any entry with an attempt to use any other mode shall be ignored at run time. Because there is no restriction on the order in which the entries are created, specifying a watch block that has not been configured will not generate an error. Likewise care must be taken to ensure that the configuration of the event table and the watch blocks (as well as the report blocks) are consistent and correct. Status The value of this object indicates the current status of this row in the table. Description This object may be used to define a description of this watch block. Block Value An OER (Octet Encoding Rules) encoded string of all object values defined in watchobjectdefinitiontable, pointed at by watchoid (in watchid order) where the watchblock IS watchblocknumber AND the watchstatus IS available. Report Object Table Parameters Status The value of this object indicates the current status of this row in the table. Block This object contains the block number to assign to the log object associated with this row in the reportobjectdefinitiontable. This value shall not exceed the value indicated by the maxreportblocks object. O.I.D This object contains the object identifier of the object to log.

184 Chapter 5 Editing a Controller Database TRANSIT SIGNAL PRIORITY MODULE Transit Signal Priority (TSP) functionality allows a user to maximize the opportunity for transit vehicles to pass through an intersection with fewer stops and delays, while minimizing impacts to normal traffic operations. In this module, TSP functionality can be configured to manage detection definition, processing, and transitioning, in two modes of operation. In the actuated mode, check-in / check-out detection parameters manage actuated control in a coordinated environment. The normal green reduction and green extension modes employ user-defined control strategies to adjust the green phase. Split Balancing is supported, to allow for recouping time during the next cycle. In Pretimed mode, operations can also be configured and implemented via action plans based on time of day and day of week scheduling. A Queue Jumping feature can also be applied, that does more than simply modify timing. Activating Queue Jump output for a programmed interval allows the transit vehicle in a by-pass lane, to move ahead of waiting queues of traffic in response to an early green signal. This module can be opened by clicking on the Transit Signal Priority button ( controller toolbar. ) in the Figure 74 Transit Signal Priority Window The TSP data objects parameters are split between five screens in this module: the Configuration, Input, Input Configs, Action Plan, and Q Jumps tables. Configuration Table Parameters The Configuration Table allows the user to enable or disable the TSP operation, and provides an index to system and default action plans for actuated and pretimed system command patterns. TSP Enable A value of tspdisable (0) disables all tsp functionality whereas a value of (1) enables NYC tsp functionality as programmed within the device. All other values are reserved by U.S. Traffic Corp. 174 ATCLink Operating Manual

185 Transit Signal Priority Module System action Plan for Actuated The index of the TSP Action Plan Table (tspactionplantable) entry to be used when running an actuated system commanded pattern (i.e. systempatterncontrol = 1..48,254). A value of zero (0) means to disable TSP during system commanded operation. The value of this object must be less than or equal to tspmaxactionplans. System action Plan for Pretimed The index of the TSP Action Plan Table (tspactionplantable) entry to be used when running a pre-timed system commanded pattern (i.e. systempatterncontrol = ). A value of zero (0) means to disable TSP during system commanded operation. The value of this object must be less than or equal to tspmaxactionplans. Default action Plan for Actuated The index of the TSP Action Plan Table (tspactionplantable) entry to be used when running free operation (pattern = 254). A value of zero (0) means to disable TSP during free operation. The value of this object must be less than or equal to tspmaxactionplans. Default action Plan for Pretimed The index of the TSP Action Plan Table (tspactionplantable) entry to be used when running pre-timed free operation (pattern = 101). A value of zero (0) means to disable TSP during free operation. The value of this object must be less than or equal to tspmaxactionplans. Input Table Parameters The input table contains an entry to define TSP parameters that are not plan (or TOD) dependent. The mode values control the action to be taken when detection occurs, providing priority to transit vehicles without interrupting plans or skipping phases. The status returns the current condition of the TSP input. Mode A value of (0) uses only the 'check-in' input and demand is placed whenever the input is active. A value of (1) uses check-in and check-out inputs to determine the duration of demand for the tsp input. A value of (2) uses check-in-plus-time to determine the duration of demand for the tsp input. Status: Indicates the current status of the TSP input. The status options are as follows: Table 57 Status Values Values Description 0 tspnone 1 tsprequest 2 tspreservice 3 tspsuccess 4 tspremoved 5 tspclearfail 6 tspdetectfail 7 tspdetectclear 8 tspabortvtcs 9 tspdelaytiming 10 tspextendtiming 11 tsppreemptoverride ATCLink Operating Manual 175

186 Chapter 5 Editing a Controller Database Input Configs Table Parameters The following parameters can be defined on a per interval/phase basis, and associated with an action plan via the configuration index. Config Index The Config number for this row in the table. This value can not exceed the value indicated by the tspmaxinputconfigs object (1-8). Delay A parameter that delays the check-out of the TSP input denoted by tspinputnumber. Value is in seconds (0-255 sec.). Extend A parameter that delays the check-out of the TSP input denoted by tspinputnumber. Value is in seconds (0-255 sec.). Fail Time A parameters that causes the TSP input to be aborted and ignored until the input transitions to the inactive state. Value is in seconds (0-255 sec.). Reservice Time A parameter that limits the time between service of the TSP input denoted by tspinputnumber. Upon completion of TSP service, the reservice timer is loaded and a subsequent service of the TSP input cannot occur until the reservice timer is timed out. Value is in seconds (0-65,535). VTT A parameter that is used to adjust the projected arrival time of the transit vehicle based on the distance between the point of detection of the transit vehicle and the stop bar for the corresponding phases. Value is in seconds (0-255 sec.). BST A parameter that is used to adjust the projected arrival time of the transit vehicle based on the typical time it takes a transit vehicle to unload passengers. Value is in seconds (0-255 sec.). Strategy This object determines the strategy used for the input plan. The following options are available: Table 58 Strategy options Value tspnormal (0) tspoffsetcorrection (1) tspsplitbalance (2) Description Reduces non-tsp green phases/intervals to reach the tsp phase/interval quickly and then extends tsp phase/interval to help the vehicle pass through the intersection. Same as tspnormal except at local-zero following tsp service, the coordinator corrects the offset error according to coordcorrectionmode and ustccoordcorrectionmode. Similar to tspnormal except whatever time is borrowed from a phase/interval is returned during the next cycle. Similarly, whatever time has been loaned to the tsp phase/interval as an extension is given back during the next cycle. Calls A parameter that determines the phases or intervals that the corresponding input calls. It is a bit packed integer where each bit represents a phase or interval. Representation is as follows: bit 0 = Phase/Interval 1 bit 1 = Phase/Interval ATCLink Operating Manual

187 Transit Signal Priority Module bit 31 = Interval 32 QJumps This object determines the intervals/phases that will activate the programmed Q jump from the Q jump table. These intervals/phases must be a subset of the object spinputconfigcalls. Action Plans Parameters This table allows the user to enable action plans for a maximum of six approaches per intersection, assigns the configuration table, and sets the re-service time applied to all tsp inputs of this plan at the end of tsp service. Plan Number The Action Plan number for this row in the table. This value shall not exceed the value indicated by the tspmaxactionplans object. Input Enables This object determines which tsp inputs are enabled for this TSP plan. Bits are only valid for TSP inputs supported by the CU. The possible inputs are: bit 0 = tsp input #1 bit 1 = tsp input #2 bit 2 = tsp input #3 bit 3 = tsp input #4 bit 4 = tsp input #5 bit 5 = tsp input #6 bit 6 = tsp input #7 bit 7 = tsp input #8 Config Index The index of the input configuration table (tspinputconfigtable) entry to be used for this plan (1-8). Master Reservice Time This object is a global (unit-wide) re-service time applied to all tsp inputs of this plan at the end of tsp service. Q Jump Table Parameters This node contains a table of the phases and intervals that require a Queue jump, and allows the user to indicate the time that a QJump output will be on. Call Phases A parameter that determines the phases that require the QJump output before the interval is brought on. It is a bit packed integer where each bit represents an interval (1-16). Call phase values are: Table 59 Call Jump Phase Values Value Description 1 Phase 1 2 Phase 2 ATCLink Operating Manual 177

191 Chapter 6 Maintenance & Troubleshooting This chapter describes how to perform the housekeeping duties within ATCLink, such as managing user accounts, database maintenance, and also provides some troubleshooting tips. The following topics are discussed in detail in this chapter: How to add and delete user accounts, on page 182. A table for troubleshooting problems encountered with ATCLink, on page 185. Technical Support, on page 185. ATCLink Operating Manual 181

192 Chapter 6 Maintenance & Troubleshooting MANAGING USER ACCOUNTS User accounts are used in ATCLink to determine who can access the software and what level of access each user is granted. By default, ATCLink is delivered with a single account already installed. The name and password for this standard account depends on whether you have the Administrator or the Manager version of ATCLink installed. Table 61 Pre-configured user accounts ATCLink Version User Name Password Administrator USTC_ADMINISTRATOR USTC_ADMINISTRATOR Manager USTC_MANAGER USTC_MANAGER Although it is fine to use these accounts when first configuring ATCLink, it is highly recommended that you create new accounts for your location, and remove the preconfigured account as a security precaution. Note If you have the Administrator version of ATCLink, be sure to create at least one Administrator level account before you delete the USTC_ADMINISTRATOR account. You will not be able to create a new administrator level account if you are logged in under a Manager level account. Viewing the List of Active User Accounts To see all of the accounts that are currently configured within your copy of ATCLink, go to the Login menu`, and choose View/Delete Users. This will present a window of all of the user accounts that have been created. This list does not display accounts that have been previously deleted. Adding New User Accounts To add new user accounts to your system, log in with the level of user that you will be adding. (i.e. If you plan to create another Administrator level account, you will need to be logged in as an Administrator-level user.) 1. Go to the Login menu, and choose Add User. The following dialog box will appear. 182 ATCLink Operating Manual

193 Managing User Accounts Figure 75 Add User dialog box 2. Enter the name you wish to assign to the new user account. Important An account name is NOT case-sensitive; however the password is case sensitive. The name and the password can each be any text string, including spaces, punctuation, capitalization, and special characters (e.g. & $! #, etc.) up to a total length of 18 characters. 3. Enter a password to assign to this account. You will not be able to see the password as you type it, so be careful when typing, and be sure to record the password somewhere in case you forget it. 4. Set the Security Level. The above window shows that the security level is set to Administrator. You can toggle this value back and forth between Administrator and Manager by using the Left-Right arrow button (shown at right). 5. To accept the new user account, select the OK button. (To close the window without creating the new account, choose the Cancel button.) This completes the creation of a new user account. To create more accounts, just go back to the Login menu and start the Add User module again. Deleting User Accounts Just as with the addition of new accounts, deleting accounts can only be performed by users logged in with the same level or higher access. This means that a Manager-level user cannot delete an Administrator account, but an Administrator-level user can delete a Manager-level account. Follow these steps to delete an account: 1. Go to the Login menu and choose View/Delete users. This will display the User List dialog box, shown in Figure 76. ATCLink Operating Manual 183

194 Chapter 6 Maintenance & Troubleshooting Figure 76 View/Delete User list 2. Select the Account name you wish to remove from the system. When you do this, the Remove User button will be activated, unless you are currently logged in as a Manager, and you ve selected an Administrator account. Note Manager-level users cannot remove Administrator level accounts, but they can delete other Manager-level user accounts. 3. If you are sure you have selected the correct account, press the Remove User button to delete the account. You will not be asked to verify this, and when deleted, the account cannot be recovered. If you delete an account accidentally, it will need to be created anew, with a new password. 4. When you are finished deleting user accounts, choose the Close button to exit from the View/Delete User list. 184 ATCLink Operating Manual
