25 Chapter 4 4 TRANSMIT VIEW A Transmit View allows you to configure settings for the transmission of messages over the network. Messages may be transmitted once (singleshot), or repetitively (broadcast). The time stamp associated with a message helps set the schedule for sending. More than one Transmit View may be opened and used at a time, to create various message transmission combinations. 4.1 Setting up the Transmit View This section provides instructions for configuring a Transmit View for the desired protocol and presents other View options. 1. Select Protocol Transmit View, or click on the Transmit icon on the tool bar. This opens a Transmit View (Figure 6) for selecting, viewing, and editing messages for transmission: Figure 6: Transmit View 15

26 After Transmit View is selected, a Transmit drop-down menu is enabled on the menu bar. The commands included in this menu are Transmit, Clear, Add Message, Delete Message, Edit Message, Load Transmit Buffer, and Save Transmit Buffer. An Edit drop-down menu is also enabled on the menu bar. The available commands include Copy and Paste, which allow the user to copy and paste messages from one view to another. 2. Click on Setup. This opens a Select Transmit Protocol Channel dialog box (Figure 7): Figure 7: Select Transmit Protocol Channel Select a Channel from the list. Select a Protocol from the list. 3. Click on OK to return to the Transmit Window. The Add Message command is enabled. The Setup button is now an Options button. Note: Available channels and protocols are determined by the hardware selected. Other operations are enabled, including the Options command, which opens a Transmit Filter/Protocol Options dialog box (Figure 8). The Broadcast variables are used only for Broadcast transmission. 16

27 Figure 8: Transmit Filter/Protocol Options Click on the Enable Echo check box to enable/disable the echo of transmitted messages in Receive Views. (Note: this check box appears only with DPA hardware.) In the Broadcast Count box, specify the number of times a message is to be sent over the network. Inputting a -1 will create a continuous broadcast. Move the cursor to Broadcast Interval to specify the interval, in msecs, between message broadcasts. Click on OK to return to the Transmit View. 4.2 Adding Messages There are several methods that may be used to add messages for transmission. Messages may be individually added or cut and pasted from other views. To add messages for transmission, you may use one of the following methods. Click on Add Message, or select Transmit Add Message, or select Edit Paste (message copied from a different view), or 17

28 select Transmit Load Transmit Buffer (reference section 4.4). The above steps cause a message (or messages) to be displayed in the Messages to transmit section of the Transmit View. With the Add Message or Transmit Add Message method, the messages will typically have to be edited for content. 4.3 Editing Messages This section describes how to manipulate messages once they are in the Transmit View. The Delete Message command will erase all highlighted messages. The Clear command will erase all messages from the view. To edit a message: 1. Double click on the message to edit it in the Messages to transmit section of the Transmit View, or single click the message to highlight it for editing. 2. Click on Edit Message, or select Transmit Edit Message. For each protocol type, a different message editor will appear. 3. Once you have entered the correct information, click OK. The message is now ready for transmitting. 4.4 Transmitting Messages There are two ways to transmit messages: single-shot or broadcast. Singleshot transmission allows one or many messages to be selected and sent once over the network. Broadcast transmission allows for a single message to be sent repeatedly over the network. Note: Different networks will have different configuration parameters. See the appropriate chapter for details: CAN & J1939, Ch. 8; J1708 & J1587, Ch. 9; J1850, Ch. 10; UBP, Ch. 11; Ford-ISO9141, Ch Single-shot Transmitting 1. To select messages, either: Click on Select All, or 18

29 Hold the Control key while clicking the left mouse button, to select individual messages, or Select the first message; then hold down the left mouse button while scrolling down the message list. All selected messages will be highlighted. Not all the messages in the Transmit View need to be selected, nor do they need to be sequential. However, they will be transmitted in the order of their time stamps. 2. Click on Transmit, or select Transmit Transmit. Hint: A Broadcast message can be used to trigger the sending of multiple messages in a Transmit View Broadcasting The setup parameters for broadcasting, Broadcast Count and Broadcast Interval, are specified in the Transmit Filter/Protocol Options dialog box (Figure 8), and you may configure them by clicking on the Options button in the Transmit View. To start broadcasting a message, highlight or click the message; then: 1. Click on Broadcast. This invokes message broadcasting. Only one message can be highlighted and used with this option. 2. Click on Stop Broadcast to stop broadcasting the message, or simply wait until the message has been sent the number of times you specified. 4.5 Loading and Saving the Transmit Buffer A transmit buffer may be saved and loaded, or reloaded, in various views. The message files are saved in binary format, with an.msg extension. NAS provides a conversion utility for translating a file into ASCII format (reference section 13.2). To load a saved buffer file, select Transmit Load Transmit Buffer. This opens a standard Windows Open dialog box. Click on the appropriate drive, folder, and filename. 19

30 To save a buffer file, select Transmit Save Transmit Buffer. This opens a standard Windows Save As dialog box. Click on the appropriate drive, folder, and filename. 20

31 Chapter 5 5 RECEIVE VIEW A Receive View is used to display messages transmitted by NAS or other nodes on the network, and to log messages to a file. The Receive View will show message decoding based on any data dictionary associated with the selected protocol. Filtering is used to remove unwanted messages from views or log files. You may open multiple Receive Views to create various receiving/logging scenarios. 5.1 Setting up the Receive View 1. Select Protocol Receive View, or click on the Receive icon on the tool bar. This opens a Receive View dialog box (Figure 9): Figure 9: Receive View 21

32 After the Receive View is selected, a Receive drop-down menu is enabled on the menu bar. The commands included in this menu are Start, Stop, Clear, Edit Filter, and Edit Options. The Edit drop-down menu is also enabled on the menu bar. Copy is the only command on this menu and is available when the receive process is stopped and a message (or messages) is highlighted. This allows the user to copy messages from the current view into another view. 2. Click on Setup. This opens a Select Receive Protocol Channel dialog box (Figure 10): Select a Channel from the list. Select a Protocol from the list. Figure 10: Select Receive Protocol Channel Note: Available channels and protocols are determined by the hardware selected. 3. Click on OK to return to the Receive View. The Options, Start, and Edit Filter commands are now enabled. 4. Click on Start, or select Receive Start. This initiates the receiving process. The counter will display the number of messages received. 5. Click on Stop, Note: Any messages previously in the Receive View will be lost (unless saved to a file) when Start is selected. 22

33 or select Receive Stop. This stops the receiving of messages. 6. Click on Clear, or select Receive Clear. This clears the received message(s) from the Received Messages section of the Receive View. 5.2 Editing a Receive View This section describes how to set up a Receive View for filters and global options. 1. Click on Options, or select Receive Edit Options. This opens a Receive Filter/Protocol Options dialog box (Figure 11). Note: With VSI hardware, Data and Time Stamp are always enabled. Figure 11: Receive Filter/Protocol Options To enable Data and/or Time Stamp display in the Receive View, click on the individual Data and/or Time Stamp check boxes in the Enable section. 23

34 In the Enable section, click on the Absolute Time check box for timestamping to be shown at a specific time interval. If the Absolute Time box is not checked, the default setting a timestamp relative to the previous message is selected. To save received messages, click on Log to File in the Log section. You may select either Binary or ASCII format. Binary files (.msg) may be reloaded into different views, while ASCII files (.log) may be easily exported to other programs. A Binary-to-ASCII conversion utility (reference section 13.2) may used offline for this task. You must click on to browse for a File Name. 2. Click on OK to return to the Receive View. 5.3 Editing Receive View Filters Receive View filters are used to limit the messages entering the view or logging file. To set up the filters: 1. Click on Edit Filter, or Select Receive Select/Edit Filter. This opens a Filter Manager dialog box (Figure 12) for specifying multiple messages filters. Up to six filters may be used in each Receive View. The global parameters available are Combination and Filter Type. Combination determines whether the filters are logically ORed or ANDed together. To have the filter condition met if a message satisfies only one of the enabled filters, click on OR the Filters. To have the filter condition met if a message satisfies all of the filters enabled, click on AND the Filters. Reference Appendix C for examples of filters. Filter Type determines whether the messages that meet the filter condition, or messages that do not meet the filter condition, are allowed to enter the Receive View. To allow those messages that match the filter condition to enter, click on Pass Filter. To allow those that do not satisfy the filter condition to enter, click on Stop Filter. 24

35 Note: Deleted filters can not be retrieved. It is best to disable temporarily unwanted filters. Note: Different networks will have different configuration parameters. See the appropriate chapter for details: CAN & J1939, Ch. 8; J1708 & J1587, Ch. 9; J1850, Ch. 10; UBP, Ch. 11; Ford-ISO9141, Ch. 12. Figure 12: Filter Manager 2. Click on Add Filter. A new filter will appear in the line-up. 3. To edit a filter, click and highlight it. This will enable Delete Filter, Edit Filter, and a check box for Filter Enabled. Clicking Delete Filter will remove any highlighted filters. 4. Click on Edit Filter. For each protocol, a different Filter Editor dialog box will appear. Click on OK to return to the Receive View. 5.4 Save As The Save As command is used to save messages to a binary file in the Receive View. It is selected under File Save As. This menu opens a standard Windows Save As dialog box. Click on the appropriate drive and folder, and enter the desired filename and format in which to save the file. Messages saved in binary format may be viewed within, and/or retransmitted from, other views. 25

37 Chapter 6 6 TRIGGER VIEW The Trigger View includes a unique combination of functions from the Transmit and Receive views that allows configuration of transmit and receive interactions. These functions allow actions to occur when certain messages are received. (An action can be an audible beep, transmission of a message buffer, or the logging of messages to a file.) While the Transmit and Receive views support transmitting and logging of messages to files, the Trigger View supports those actions only after a specific message condition occurs. The Trigger View is used to configure trigger conditions, and to create and record specific network events. 6.1 Setting up the Trigger View This section describes how to configure the Trigger View. 1. Select Protocol Trigger View, or click on the Trigger icon on the tool bar. This opens a Trigger View (Figure 13). Figure 13: Trigger View 27

38 After Trigger View is selected, a Trigger drop-down menu is enabled on the menu bar. The commands in this menu include Edit Trigger, Trigger Action, Load Transmit Buffer, and Save Transmit Buffer. 2. Click on Select Trigger Protocol. This opens a Select Receive Protocol Channel dialog box (Figure 13). Make the appropriate selection, and click on OK. 3. Click on Select Transmit Protocol. This opens a Select Transmit Protocol Channel dialog box (Figure 7). Make the appropriate selection, and click on OK. Once the protocols have been selected, the Actions, Add Message, Edit Receive Filter, and Trigger On commands are enabled. 6.2 Setting Up Actions and Log Options There are several actions and log options that may be configured in the Trigger View. To configure these options, do the following: 1. Click on Actions, or select Trigger Trigger Action. This opens a Trigger Action dialog box (Figure 14). Figure 14: Trigger Action 2. Click on the desired Action check boxes. 28

39 Selecting Transmit Message in the Buffer releases the message(s) from the Transmit Message Buffer when the trigger conditions are satisfied. Note: For details about the binary-to-ascii conversion utility, see section If the Log to File box is checked, move the cursor to the Log File section, and click on to browse for (or enter) a file name. Choose Binary or ASCII as the saved-file format. If the Log to File box is checked, select the option to log messages before, after, or both before and after the trigger. If both boxes are checked, 300 messages will be saved before the trigger and the Specified Duration time or Specified Message Count will determine the number of messages saved after the trigger. The trigger may also be disabled after one occurrence of the trigger condition. This will ensure that only one log file is created, and not overwritten. Selecting Beep creates an audio event every time the trigger conditions are met. Selecting Disable Trigger after first occurrence limits the trigger action to one occurrence. 3. Click on OK to return to the Trigger View. 6.3 Creating Triggers There are up to six triggers allowed in one Trigger View. To create and edit triggers, perform the following steps. 1. Click on the Edit Trigger icon, or select Trigger Edit Trigger. This opens a Trigger Manager dialog box (Figure 15) with Add Trigger, Delete Trigger, Edit Trigger, Trigger Sequence Options, and Pass Count options. Trigger Sequence offers Strict Order, Any Order, or Any Trigger options. Strict Order means the global trigger is set only if all the event triggers occur in the exact order in which they are listed. Any Order sets the global trigger after all the event triggers have 29

40 occurred once, in any order. Any Trigger means that only one event trigger occurrence can set the global trigger. Pass Count allows the global trigger condition to be met a specified number of times before actions are evoked. Figure 15: Trigger Manager 2. Click on Add Trigger. A new trigger will be added to the Triggers list, and the Delete Trigger and Edit Trigger commands will be enabled. Clicking and highlighting the trigger will create a Trigger Enabled option. 3. Highlight a trigger, and click on Edit Trigger to configure it. For each of the network types, the Trigger Editor dialog box will appear exactly as the Filter Editor box did for that protocol type. 4. Click on OK to return to the Trigger View. The active trigger message will be displayed. 6.4 Editing the Receive Filter Receive filters in the Trigger View are used to determine which messages get logged to a file. Using a tri-state method, these filters can eliminate messages that normally pass through a single optimized filter. To use the Receive filter, click on Edit Receive Filter. For each of the network types, a different Filter Editor dialog box will appear. After you have made your edits, click on OK to return to the Trigger View. Note: Different networks will have different configuration parameters. See the appropriate chapter for details: CAN & J1939, Ch. 8; J1708 & J1587, Ch. 9; J1850, Ch. 10; UBP, Ch. 11; Ford-ISO9141, Ch. 12. Note: The Trigger View functions properly only if the active filter allows the specified trigger-event-causing messages to enter the view. 30

41 6.5 Creating the Transmit Message Buffer The Transmit Message Buffer is used to send messages on the network after the trigger conditions have been satisfied and the Transmit messages in the buffer box in the Trigger Action dialog box is checked on. The configuration of the buffer is the same as that of the Transmit View-; messages can likewise be added or edited Adding Messages To add a message to the Transmit Message Buffer, do one of the following. Click on Add Message, or Select Edit Paste (message copied from a different view), or Select Transmit Load Transmit Buffer (reference section 4.5). This displays a message in the Transmit Message Buffer section of the Trigger View Editing Messages To edit a message in the Transmit Message Buffer, perform the following steps. Note: Different networks will have different configuration parameters. See the appropriate chapter for details: CAN & J1939, Ch. 8; J1708 & J1587, Ch. 9; J1850, Ch. 10; UBP, Ch. 11; Ford-ISO9141, Ch Double click on the message you wish to edit, or click on the message you wish to edit; then click on Edit Message. 2. Edit message specifics by moving the cursor to the appropriate boxes and entering information, or by clicking on the down arrow to display a list of options for selection. For each protocol, the parameters will be different. 31

44 After Gauge View is selected, a Gauge drop-down menu is enabled on the menu bar. The User Range command appears on this menu. 2. Click on Setup. This opens a Select Receive Protocol Channel dialog box in which to select the appropriate channel and protocol. 3. Click on OK to return to the Gauge View. 4. Click on Edit Gauge to open a Gauge Info dialog box (Figure 17) for setting up the gauge display. There are three parameter types: Scaled, Bit-mapped and Floating Point. Floating Point and Scaled parameters use the same [Gauge Info] dialog box. Figure 17: Gauge Info - Scaled and Bit-mapped To specify identifier (or header) and data bits for the gauge to filter, click on Edit Filter (to open a Filter Editor dialog box). For each protocol type, the dialog box will look different. Select the encoding format type. The available formats are Intel, Motorola A and Motorola B. See the following tables for encoding examples. In the Bit section, enter values for Start Byte, Start Bit and Length. These parameters locate the data to be translated. Examples of encoding parameters for the different format types are shown below: Note: Different networks will have different configuration parameters. See the appropriate chapter for details: CAN & J1939, Ch. 8; J1708 & J1587, Ch. 9; J1850, Ch. 10; UBP, Ch. 11; Ford-ISO9141, Ch

45 Example: For Start Byte = 2, Start Bit = 2, Length = 17 Start Byte Bit Intel Encoding Format Start Byte Bit Motorola A Encoding Format Start Byte Bit Motorola B Encoding Format Type in the Parameter Name. Select the Parameter Type: Scaled, Bit-mapped or Floating Point. Scaled parameters allow the user to input scaled values. Bitmapped parameters create a gauge that displays individual bits. Floating Point parameters decode values, using the IEEE/ANSI standard. 35

46 For Scaled parameters, the Scale elements must be input as decimal values. The Resolution value is multiplied by the data value, and Offset shifts the value by a constant. A translation example follows. Length = 8 bits (1 byte): Resolution = 0.25, Offset = 50 If byte = 80H = 128 Decimal (128 * 0.25) + 50 = 82 The gauge will display 82 units. For Scaled and Floating Point parameters, the Display Range elements must be input as decimal values. High is the upper limit of the converted data to be displayed; Low is the lower limit. For Scaled and Floating Point parameters, the User Range elements must be input as decimal values. High is upper limit of the converted data to be displayed; Low is the lower limit. These values may be smaller than the Display Range resolution values. For Scaled and Floating Point parameters, the Negative Number parameter may be clicked on or off. For Scaled and Floating Point parameters, the Unit may be displayed on the gauge, for reference. For Bit-mapped parameters, a Bit Interpretation box is provided. The information typed here will be displayed on the gauge, for reference. 5. After the information is entered, click on OK. The Gauge (Figure 18) will be displayed: 36

47 Figure 18: Gauge View - Scaled and Bit-mapped 7.2 Starting the Gauge View Once the gauges have been set up, you may turn them on by clicking the Start button. When a message is transmitted, Value, Units and Description are displayed in the Scaled Gauge View. In the Bitmapped Gauge View, specific bits are shown as logic one (highlighted) or logic zero (nonhighlighted). Click the Stop button to turn the gauge off. This enables the Setup button, for making necessary changes in the Gauge Info box. 37

49 Chapter 8 8 CAN and J1939 Specifics NAS supports Standard CAN (11-bit identifier), Extended CAN (29-bit identifier), and a J1939 Data Dictionary. There are specific screens for each of these protocols / dictionaries, to use when configuring the network, editing messages, or using filters and triggers in various views. 8.1 Configuring the Channel Configuration of the network baud rate is the same for all CAN and J1939 Data Dictionary options. To access the CAN Configuration dialog box: 1. Select Setup Configure Channels, or click on the Configure Channels icon on the tool bar. A Select Channels dialog box (Figure 19) will appear. Figure 19: Select Channels 2. A channel s configuration can only be changed when the channel is disconnected. If the channel is connected, click on Disconnect (or press the ESC key), then Configure, to open a CAN Configuration dialog box (Figure 20) for customization of the channel. 39

50 There are two ways to configure the baud rate in the current dialog box: enter the BTR0 and BTR1 parameters, or enter the individual (SJW, BRP, TSEG1, TSEG2) parameters and Sampling Mode. (A third way to configure the baud rate is to click the Select Baud Rate button and use the CAN Baud Rate Calculator to search valid values for you.) Figure 20: CAN Configuration (Datalink Name and Protocol reference the hardware selected and are not configurable.) BTR0 BTR1 SJW Bus Timing Register 0: defined as the values of BRP and the SJW. Bus Timing Register 1: defined as the values TSEG1, TSEG2, and sampling mode. Synchronization Jump Width: jump width needed to resynchronize the CAN node to the network. Note: For further information regarding these parameters, see Related Documents, Section 1.3. BRP Baud Rate Prescaler: programmable, determines the individual bit timing in relation to the period of the system clock. 40

51 TSEG1 TSEG2 Time Segment 1: determines the sampling point within a bit period, which is at the end of TSEG1. Time Segment 2: provides additional time needed to generate the next bit, using the value just sampled. Sampling Mode: The number of bit samples (one or three). When the Select Baud Rate button is used to configure the baud rate, the CAN Baud Rate Calculator appears as the CAN Baud Rate dialog box (Figure 21). To use the calculator, perform these steps. 1. Enter the baud rate into the Enter Baud Rate box, and a tolerance percentage into the Tolerance box. Check the Display BTR in Hex check box to display results in HEX, or leave it un-checked to display results in decimal (DEC) form. 2. Click the Search button to generate the list of possible parameter settings for the specified baud rate. 3. Select a configuration by highlighting the desired row of values, and click the OK button. The CAN Configuration dialog box will then reflect these changes. Figure 21: CAN Baud Rate Click on OK to return to the initial screen. 41

52 8.2 Editing a Message Message editing is done the same way in Standard CAN as it is in Extended CAN. The J1939 Data Dictionary uses a different editor that is specific to its protocol CAN Message Editor The only difference between the message editors in Standard and Extended CAN is the length of the identifier field: 11-bit (in Standard CAN) or 29-bit (in Extended CAN). To access the CAN Message Editor (Figure 22), perform these steps. 1. Add a message to the Messages to transmit section in the Transmit View or the Transmit message buffer section in the Trigger View. 2. Double click on the message, or single click on the message, and select Edit Message. The CAN Message Editor will appear. You must enter the following parameters to construct your message: Message Header, Data Count, Message Data, and Time Stamp. For the Transmit view, the Time Stamp value is absolute, relative to the start of transmission. You may select Hex (hexadecimal) or Dec (decimal) format for viewing the message parameters. Click OK to return to the Transmit or Trigger View. Note: Time stamps entered will be honored as accurately as possible. Figure 22: CAN Message Editor 42

53 8.2.2 J1939 Message Editor In the J1939 Data Dictionary, a PGN Editor (Figure 23) is used to construct or edit messages for transmitting. To access the editor: 1.
