3 Starting the BACdrop Setup Wizard You can run the BACdrop Setup Wizard at any time. The PC does not need to be connected to a BACdrop gateway when you start the program. To start the BACdrop Setup Wizard 1. On the Start menu, point to Programs, BACdrop Setup Wizard, and then choose the BACdrop Setup Wizard program. 2. Type the password in the box. The password is BACdrop! (case sensitive). 3. Click OK or press Enter. The Main screen appears. BACdrop Setup Wizard, Main Screen Working With the BACdrop Gateway This section describes the BACdrop Setup Wizard tools that allow you to interact with the BACdrop gateway by means of a serial cable connection. With these tools you can gather information about the MicroTech network configuration, set up or change the BACdrop configuration file, and download program files to the BACdrop gateway. You can also back up and restore BACdrop configuration files. All of these tools can be found under the BACdrop Panel menu: System Information Configure: Modify Controller List Configure: Change Network Numbers Download Displays a list of the MicroTech controllers connected to the BACdrop gateway. This command also displays the BACnet network number and the MicroTech network number. Displays a list of the MicroTech controllers and the address of each. It also displays the Device instance number and the location of the controller. You can edit the controller list with this tool. Allows you to change the network number of either the BACnet network or the MicroTech network. Allows you to download software into the BACdrop gateway.

4 Advanced Options: Write Configuration to a File Advanced Options: Read Configuration from a File Advanced Options: Change Timing Parameters Saves a BACdrop configuration file to the PC s hard disk or a floppy disk. Reads and restores a BACdrop configuration file that was previously saved to disk. Allows you to change the amount of time the BACdrop gateway waits for responses to MicroTech network requests before timing out. These parameters should only be changed by advanced users because improper values can cause network problems. To use a tool on the BACdrop Panel menu On the BACdrop Panel menu, choose one of the above tools. The tool s wizard starts and leads you through the setup. You will be asked to verify cable connections and the COM port to be used. See below for more information on each tool. PC Hardware and Cabling Configurations This set of tools requires a standard serial cable (not a null-modem serial cable), which is connected between the PC serial port and the BACdrop gateway s PC port. The connector on the BACdrop gateway is a female DB9. You should know the COM port that is assigned to the PC s serial port. The wizard will prompt for this information. The first screen of each tool s wizard is a cabling diagram that helps you set up or verify cable connections. An example is shown below. Typical Cabling Configuration Screen for BACdrop Panel Tools MicroTech BACdrop Setup Wizard Online User s Guide Page 4

5 System Information Tool The System Information tool displays basic information about the BACdrop gateway and its network configuration. Some of the information may be useful to you, and some of it may be useful to the BAS system integration technicians. You can view the information, but you cannot change it with this tool. System Information Tool, BACdrop Screen Following are brief descriptions of each information field: BACdrop MAC (Ethernet) Address BACdrop MicroTech Address Configured MicroTech Controller Count Network Numbers (decimal) Version Information System Error Information The address of the BACdrop gateway on the Ethernet network. It is assigned by the manufacturer of the Ethernet interface adapter and cannot be changed. The address of the BACdrop gateway on the MicroTech network. This address can be changed with the BACdrop Setup Wizard s Configure Controller List tool. Typically, a BACdrop gateway s MicroTech address will be The total number of MicroTech controllers that have been defined in the BACdrop configuration file. Usually this number will match the number of MicroTech controllers on the network, but there can be exceptions; for example, a series-100 centrifugal chiller s display processor will exist on the MicroTech network but will not be configured in the gateway. BACnet numbers assigned to the MicroTech network and the BACnet network that the BACdrop gateway is part of. The BAS system integrator may supply these numbers. They can be changed with the BACdrop Setup Wizard s Configure Network Numbers tool. The version numbers of the BACdrop gateway s program and operating system. If necessary, the BACdrop program can be upgraded by using the BACdrop Setup Wizard s Download tool. Displays any software loading errors that have occurred. For example, if the PMF fails to load or the Ethernet adapter driver fails to load, an error message will appear. Click the More button to view a list of the MicroTech controllers configured in the BACdrop gateway, or click the Main Screen button to return to the Main screen. If you click the More button, the BACdrop configuration file is read out of the gateway s memory and displayed. See figure below. Each MicroTech controller that has been entered into the configuration file is shown with its MicroTech address, controller name or type, and Device instance number. You can view the information, but you cannot change it with this tool. Click the Main Screen button to close the System Information tool and return to the Main screen. MicroTech BACdrop Setup Wizard Online User s Guide Page 5

6 System Information Tool, BACdrop Configuration File Screen Configure Controller List Tool With the Configure Controller List tool, you define the MicroTech controllers that the BACdrop gateway will translate data for. This definition includes the MicroTech network address, the standard MicroTech controller type, and the BACnet Device object instance number. You can add, delete, or modify any of this data. As an option, you can specify a MicroTech controller s location, which becomes the value of the BACnet Device object s Location property. The main screen for the Configure Controller List tool is shown in the figure below. Before this screen appears, the BACdrop Setup Wizard reads the configuration file out of the BACdrop gateway and makes a copy in the PC s memory. Any changes made to the configuration exist only in the PC s volatile memory until they are saved by clicking the Finish button. When changes are saved, they are written directly to the BACdrop gateway s nonvolatile memory. (It is not possible to save a configuration file to the PC hard disk with this tool.) Configure Controller List Tool, Main Screen MicroTech BACdrop Setup Wizard Online User s Guide Page 6

7 Adding a Controller to the Configuration File Click the Add button to add a new controller to the configuration. When you do this, the Configure Controller List edit screen appears. See figure below. Following are descriptions of the data-entry fields: MicroTech Address Device Type Device Instance Location The MicroTech network address for the controller. Each MicroTech network address must be unique on the MicroTech network. The wizard will warn you if you inadvertently enter a duplicate address. For more on MicroTech addresses, see About the Network Address in the Network Commissioning section of IM 689. The type of the MicroTech controller, which from the perspective of the BAS is a BACnet Device. Select the Device type from the drop-down list box. The Device type entries come directly from the BACdrop PMF. The first part of each entry is the prefix of the MicroTech software IDENT. The IDENT code is listed to help you quickly identify the proper controller type. The instance number for the BACnet Device. This number becomes part of the Device object s Object_Identifier property. The BAS system integrator may provide Device instance numbers. If you know the Device instance number, enter it over the default value. Otherwise, just use the default value which the Setup Wizard automatically increments. (The BACdrop Setup Wizard arbitrarily starts the numbering at 10,000.) If necessary, Device instance numbers can be changed later. Each BACnet Device instance number must be unique on the entire BACnet internetwork. The physical location of the MicroTech controller or BACnet Device. The Location information is optional. It is not needed or used by the BACdrop gateway, but if entered, it will be visible on the BACnet network as the Location property of the Device object. After you have entered the new data on the Configure Controller List edit screen, click Done to accept the changes or click Cancel to cancel the changes. When you accept the changes here, the new configuration is held in PC memory; it is not permanently saved yet. After leaving the edit screen, you will be returned to the Configure Controller List main screen. At this point you can continue to add, delete, or modify controllers, or you can save the completed configuration to the BACdrop gateway s non-volatile memory by clicking the Finish button. If you click the Cancel button on the main screen, all changes made to the configuration file in PC memory will be lost, and the original configuration file in the BACdrop gateway will remain unchanged. Configure Controller List Tool, Edit Screen MicroTech BACdrop Setup Wizard Online User s Guide Page 7

8 Deleting a Controller from the Configuration File To delete a controller from the configuration, simply select it on the Configure Controller List main screen and then click the Delete button. The new configuration is held in PC memory; it is not permanently saved yet. At this point you can continue to add, delete, or modify controllers, or you can save the completed configuration to the BACdrop gateway s non-volatile memory by clicking the Finish button. If you click the Cancel button on the main screen, all changes made to the configuration file in PC memory will be lost, and the original configuration file in the BACdrop gateway will remain unchanged. Modifying a Controller in the Configuration File To modify a controller in the configuration, simply select it on the Configure Controller List main screen and then click the Modify button. When you do this, the Configure Controller List edit screen appears. See figure above. For descriptions of the data-entry fields, see Adding a Controller to the Configuration File above. After you have entered the new data on the Configure Controller List edit screen, click Done to accept the changes or click Cancel to cancel the changes. When you accept the changes here, the new configuration is held in PC memory; it is not permanently saved yet. After leaving the edit screen, you will be returned to the Configure Controller List main screen. At this point you can continue to add, delete, or modify controllers, or you can save the completed configuration to the BACdrop gateway s non-volatile memory by clicking the Finish button. If you click the Cancel button on the main screen, all changes made to the configuration file in PC memory will be lost, and the original configuration file in the BACdrop gateway will remain unchanged. Configure Network Numbers Tool With the Configure Network Numbers tool, you define the numbers of the MicroTech network and the BACnet network that the BACdrop gateway is part of. These BACnet numbers are used for routing messages back and forth across the gateway. Like the controller list data, the network number data is part of the BACdrop gateway s configuration file. The BAS system integrator may provide the network numbers for you to enter. See figure below. After changing one or both network numbers, you can save the completed configuration to the BACdrop gateway s non-volatile memory by clicking the Finish button. If you click the Cancel button, any changes to the network numbers will be lost, and the original configuration file in the BACdrop gateway will remain unchanged. Configure Network Numbers Tool Download Tool The Download tool allows you to download updated BACdrop program files and PMF files into the BACdrop gateway s non-volatile memory. These files are available on McQuay International s McQuay OnLine bulletin board system. See the BACdrop Software section of IM 689 for more information. The Download tool is very easy to use. After the cabling configuration and COM port selection screens, a standard File Open dialog box appears, prompting you to select or browse for the file to be downloaded. You can select either a BACdrop program file (e.g., BDRPv157.exe) or a PMF (e.g., PMFv107.tab). Select the drive, MicroTech BACdrop Setup Wizard Online User s Guide Page 8

9 folder, and file you want to download and then click the Open button. The download confirmation screen appears. See figure below. Download Tool, Confirmation Screen When you click the Next button, the file begins to download and the Downloading File dialog box appears showing the progress of the download. If desired, you can cancel the download in progress. Write Configuration to File (Backup) Tool With the Write Configuration to File tool, you can save a backup copy of the BACdrop configuration file to your PC s hard disk or a floppy disk. If you ever need to replace the SBC or its flash memory chip, the saved configuration file can then be quickly restored with the Read Configuration From File tool (see below). You may also want to use this tool if you are setting up two or more very similar BACdrop networks. A completed configuration file can be copied to disk, restored to another BACdrop gateway, and then edited. The wizard includes a standard File Save dialog box, which will prompt you to enter a name and location for the configuration file to be saved. Long file names are okay, and you do not need to enter the.cfg file extension. When you click the Save button in the File Save dialog box, the BACdrop Setup Wizard will read the configuration data out of the gateway and write it to a file in the specified location. Read Configuration From File (Restore) Tool If you have a previously saved BACdrop configuration file on disk, you can restore it to any BACdrop gateway with the Read Configuration From File tool. See Write Configuration to File (Backup) Tool above for more on saving BACdrop configuration files. After restoring a configuration file, you may want to edit it with the Configure tools. The wizard includes a standard File Open dialog box, which will prompt you to select or browse for the configuration file to be restored. Previously saved configuration files have a.cfg file extension. When you click the Open button in the File Open dialog box, the BACdrop Setup Wizard will read the configuration file from the specified disk and write it to the BACdrop gateway. Change Timing Parameters Tool (Advanced Users Only) The Change Timing Parameters tool allows advanced users to adjust two timing limits for read and write operations. Default values are preprogrammed and, in most applications, should not require adjustment in the field. The timing parameters are part of the BACdrop configuration file. Discussion of the timing parameter functions is beyond the scope of this document. Only qualified and trained technicians should attempt to adjust them after consulting with personnel in the McQuay Controls group. MicroTech BACdrop Setup Wizard Online User s Guide Page 9

10 Working With the MicroTech Network Through the BACdrop Gateway This section describes the BACdrop Setup Wizard tools that allow you to interact with the MicroTech network from the BACnet side of the gateway. You can verify communications to each MicroTech controller, and you can read from and write to each controller by using its BACnet objects. A data packet logging tool allows advanced users to monitor network messages sent between the BAS and the BACdrop gateway. All of these tools can be found under the BACnet Network menu: Network Diagnostic Network Read/Write Log BACnet Packets Scans the MicroTech network for each controller defined in the BACdrop configuration file. If a controller is found, its software IDENT is read and displayed. If a controller is not found, an error message is displayed. This tool is used to verify network communications during network commissioning. Allows you to read from or write to memory locations within MicroTech controllers by using their mapped BACnet objects. Allows you to log BACnet data packets or all LAN packets to a file. This tool is useful only to advanced users. To use a tool on the BACnet Network menu On the BACnet Network menu, choose one of the above tools. The tool s wizard starts and leads you through the setup. You will be asked to verify cable connections and the Ethernet adapter to be used. The Network Diagnostic tool will also ask about the COM port to be used. See below for more information on each tool. PC Hardware and Cabling Configurations To use this set of tools, your PC must be equipped with an Ethernet adapter that has a 10BaseT connection. Every tool in this set uses an Ethernet connection, but the cabling configurations vary with the tool used. For the Network Diagnostic tool, a direct Ethernet connection and a serial cable connection is required. A direct Ethernet connection can be made with a 10BaseT crossover (or null) cable or with two standard 10BaseT cables and a hub. See figure below. BACnet Network Diagnostic Tool, Cabling Configuration Screen For the Network Read/Write tool, the Ethernet connection can be direct (as shown in the wizard) or over a BACnet BAS or LAN. A direct Ethernet connection can be made with a 10BaseT crossover (or null) cable or with two standard 10BaseT cables and a hub. A serial connection is not required. See figure below. MicroTech BACdrop Setup Wizard Online User s Guide Page 10

11 Network Read/Write Tool, Cabling Configuration Screen For the Log BACnet Packets tool, the Ethernet connection must be over the BACnet BAS or LAN. This is because the BACdrop gateway is a passive device and without a supervisory BAS to initiate requests, no communications will occur. See figure below. Log BACnet Packets Tool, Cabling Configuration Screen Each tool s wizard will present a screen that asks you to select the PC Ethernet adapter to be used. The screen will look similar to the one shown below. Note: You should verify that the PC Ethernet adapter is installed and working properly before using the BACdrop Setup Wizard. The installation and setup of a PC Ethernet adapter is beyond the scope of this document. Select Ethernet Adapter Screen MicroTech BACdrop Setup Wizard Online User s Guide Page 11

12 BACnet Network Diagnostic Tool The BACnet Network Diagnostic tool makes a single pass through the MicroTech network, attempting to communicate with every controller defined in the BACdrop configuration file. It generates a report for each controller that shows the controller s status and, if it is communicating, its software IDENT. See figure below. You can start another network diagnostic test by clicking the Refresh Screen button. To stop a test in progress, click the Stop Diagnostic button. It is worth noting that the IDENT is read from each controller s memory; it does not come from the BACdrop configuration file. These actual controller IDENTs can be used to verify software compatibility between the MicroTech controllers and the BACdrop PMF. The importance of software compatibility is discussed in the BDIP documents and in the BACdrop Software section of IM 689. The BACnet Network Diagnostic tool is very valuable during network commissioning because it can prove good communications throughout the entire system supplied by McQuay International, from the Ethernet port on the BACdrop gateway to the last MicroTech controller at the end of the daisy chain. If a BAS cannot communicate with one or more MicroTech controllers but the BACnet Network Diagnostic tool can, the problem is almost certainly on the BAS side of the gateway. BACnet Network Diagnostic Tool Network Read/Write Tool The Network Read/Write tool allows you to read from or write to a MicroTech controller in the same manner that a BACnet BAS would; that is, by using BACnet objects. When you read or write using BACnet objects, the BACdrop gateway translates the requests and sends them to the specified MicroTech controllers. This tool can thus be used to test the BACdrop gateway s point mapping functions. It can also be used to verify communications to a particular controller. See figure below. When you use the Network Read/Write tool, you need at least two documents: (1) a prepared address schedule that lists each MicroTech controller next to its MicroTech network address and (2) the BDIP for each controller type to be read from or written to. The BDIP documents list all BACnet objects in each MicroTech controller type, including engineering units and the meanings of enumerated object codes (e.g., 1 means Auto ). For example, suppose that you want to read the mixed air temperature in the self-contained air conditioning unit on the 5th floor. The address schedule might tell you this unit is at address 05.00, and BDIP document BD 08-6 would tell you that the mixed air temperature is Analog Input object 7. You must also know the MicroTech network number to use the Network Read/Write tool. You can find the MicroTech network number by using the System Information tool. MicroTech BACdrop Setup Wizard Online User s Guide Page 12

13 Network Read/Write Tool Reading from Objects When you select the Read function at the top of the screen, you can read either the Present_Value property or the Object_Name property from any BACnet object mapped to any configured MicroTech controller. After entering all required information, click the Send button and the Setup Wizard will attempt to gather the data. If successful, a message box that shows the requested information will appear. If not, the resultant message box will show unknown object. Writing to Objects When you select the Write function at the top of the screen, you can write the Present_Value property to any BACnet Analog Output or Binary Output object mapped to any configured MicroTech controller. After entering all required information, click the Send button and the Setup Wizard will attempt to write the data. If successful, a message box that says The write was successful will appear. If not, the resultant message box will show unknown object. The write function is somewhat forgiving in that it will automatically round values that have unsupported resolution and limit values that are outside the object s valid range. For example, if an Analog Output object has a resolution of 1 F and a valid range of 40 to 80 F, an entered value of 61.1 F will be written as 61 F and an entered value of 81 F will be written as 80 F.! CAUTION Application knowledge required. Can cause equipment damage. Extreme care should be taken when writing values to MicroTech controllers because unit operation can be adversely affected. Though unlikely, equipment damage is possible if an unreasonable value or combination of values is written to a controller. In most cases, MicroTech software has the capability to reject out-of-range values, but even valid values can cause problems in certain situations. You must thoroughly understand the MicroTech control application before writing any value to a MicroTech controller. Working With MicroTech Controllers This section describes the BACdrop Setup Wizard s MicroTech Controller Configure tool, which allows you to work with individual MicroTech controllers by means of a direct connection. With this tool you can gather information about a MicroTech controller s port speeds, port configurations, checksums, and software IDENT. If necessary, you can also use it to change port speeds and port configurations. To use the MicroTech Controller Configure tool On the MicroTech Controller menu, choose the Configure tool. The tool s wizard starts and leads you through the setup. You will be asked to verify cable connections and the COM port to be used. See below for more information. MicroTech BACdrop Setup Wizard Online User s Guide Page 13

14 PC Hardware and Cabling Configurations This tool requires a MicroTech PC communications cable, which is connected between the PC serial port and the MicroTech controller s A port (see note below). This special cable is available in a kit from McQuay International. The part number for the DB9-style cable kit is The kit includes adapters for the various MicroTech controller port styles. You should know the COM port that is assigned to the PC s serial port. The wizard will prompt for this information. The first screen of the tool s wizard is a cabling diagram that helps you set up or verify the cable connection. See figure below. MicroTech Controller Configure Tool, Cabling Configuration Screen Note: If you cannot communicate with a MicroTech controller through its A port, try the B port after first changing the hex switch setting to FF and cycling power. The special FF hex switch setting temporarily forces the port configuration of port B to TTY at 9600 baud. (It also forces the port configuration of port A to TTY, but at only 1200 baud.) MicroTech Controller Configure Tool The basic information collected by the MicroTech Controller Configure tool can be used to troubleshoot communications problems that may occur with specific MicroTech controllers. For example, if all but one unit ventilator is communicating on the network, you could use this tool to check the non-communicating controller s port configuration (e.g., it might be set up as level 3 instead of level 2). See figure below. MicroTech Controller Configure Tool, Information Screen MicroTech BACdrop Setup Wizard Online User s Guide Page 14

15 Following are brief descriptions of each information field: MicroTech Address Controller Series Program IDENT Communication Port Speeds Communication Port Configuration Checksums The actual MicroTech network address that the controller is using. For a level-2 controller, the first part of the address should match the hex switch setting. For a level-3 controller, the last part of the address should match the hex switch setting. If this is not the case, check the controller level and/or try cycling power to the controller. The style of the MicroTech controller. Different style controllers have different memory maps. The program identification code for the actual MicroTech program that is loaded in the controller. The configured data transmission speeds for the two communications ports. These configured speeds can be changed with this tool. The port configurations of the two communications ports. The controller level is part of the port configuration. The port configuration can be changed with this tool. The most common level-2 configuration is shown in the above figure. The checksums for the controller. The checksums must match; otherwise, the controller s program will not run. When you change port speeds or configurations, the Setup Wizard will automatically adjust the Actual checksum to match the EOS Calculated checksum. Click the Configure button to change the MicroTech controller s port configuration or port speeds, or click the Main Screen button to return to the Main screen. Clicking the Refresh Screen button will cause the information to update. If you click the Configure button, the Setup Wizard will warn you that the tool cannot be used on certain types of MicroTech controllers. Those controllers have special programming and changes to their port configurations can be made only from their keypad/displays. If the controller you are connected to is not one of those listed, proceed to the edit screen. See figure below. If the checksums do not match, the tool will not allow you to proceed to the edit screen. In this instance, MicroTech Monitor software should be used instead. The edit screen allows you to select new settings for the port speeds and port configuration. After making any changes, click the Next button to write them to the MicroTech controller. The setup Wizard will automatically calculate and adjust the Actual checksum to match the EOS Calculated checksum.

16 Working With the MicroTech Network Through an RS-232 to RS-485 Converter This section describes the BACdrop Setup Wizard s MicroTech Network Diagnostic tool, which allows you to verify communications on the MicroTech network from the MicroTech side of the gateway. In this network diagnostic test, the BACdrop gateway is bypassed. The level-1 controller (e.g., BACdrop or CSC) is temporarily disconnected, and the PC and an RS-232 to RS-485 converter take its place. To use the MicroTech Network Diagnostic tool 1. Disconnect the level-1 controller from the MicroTech network. If the BACdrop gateway is the level-1 controller and it is in the middle of the daisy chain, make sure the trunk remains continuous after disconnecting it. If the level-1 controller is a MicroTech supervisory controller (CSC, RMS, RMC, LLLB), disconnect it by unplugging its B port AMP connector. 2. On the MicroTech Network menu, choose the Network Diagnostic tool. The tool s wizard starts and leads you through the setup. You will be asked to verify cable connections and the COM port to be used. The Network Diagnostic tool will also ask about the number of level-2 controllers on the network. See below for more information. PC Hardware and Cabling Configurations This tool requires an RS-232 to RS-485 converter and power supply (e.g., B&B Electronics models 485PTBR and 485PS2). The RS-485 end taps into the MicroTech network at any location on the level-2 trunk, and the RS-232 end connects to your PC s serial port with a standard serial cable. See figure below. MicroTech Network Diagnostic Tool, Cabling Configuration Screen MicroTech Network Diagnostic Tool The MicroTech Network Diagnostic tool makes a single pass through the MicroTech network, attempting to communicate with each level-2 controller on the network, up to the number entered on the wizard screen. Any level-3 controllers associated with a level-2 controller are also scanned. If a controller is found, its software IDENT is read and displayed. If a controller is not found, an error message is displayed. The tool generates a report for each controller that shows the controller s status and, if it is communicating, its software IDENT. See figure below. You can start another network diagnostic test by clicking the Refresh Screen button. To stop a test in progress, click the Stop Diagnostic button. You can also save the test results to a text file by clicking the Write to File button. It is worth noting that the IDENT is read from each controller s memory. These actual controller IDENTs can be used to verify software compatibility between the MicroTech controllers and the BACdrop PMF. The importance of software compatibility is discussed in the BDIP documents and in the BACdrop Software section of IM 689. MicroTech BACdrop Setup Wizard Online User s Guide Page 16

17 The MicroTech Network Diagnostic tool is not capable of communicating with a level-1 MicroTech controller, and it is not capable of communicating with a BACdrop gateway regardless of its level. MicroTech Network Diagnostic Tool MicroTech BACdrop Setup Wizard Online User s Guide Page 17
