    EDR, but in most cases, they want to both send and receive data. Using WITS is a proven and reliable way to accomplish these goals.

  • Page 7: Understanding Pason Wits

    The Pason system uses WITS Level 0 for serial communications. In Send and Receive mode, the EDR transmits a number of WITS Level 0 packets (1 packet in Half WITS mode, approximately 8 packets in Full WITS mode) each time it receives a valid WITS Level 0 packet.
  • Page 8 The EDR uses this header to distinguish between sent data and received data. If a WITS device requires the removal of the 1984PASON/EDR header, ensure that the device is connected to the EDR via a COMM022, and that its EDR comm port is set to Send Only.

  • Page 9: Connecting Hardware For Wits Communication

    Specifically, note that the RS-232 ports on trailer access points (TAPs) do not support WITS connections. WITS connections to TAPs haven’t been fully tested and their reliability is unknown. Connecting a WITS device to a DHC or SideKick can in some cases adversely affect wireless communications between the DHC and the network.

  • Page 10: Connecting A Wits Device Via The Toolpush Connection Box Or Network Panel Using A Comm022

    Note: Pason COMM022 communication (comm) boxes ship with full duplex communication enabled. COMM022 comm boxes have a jumper that enables you to choose half or full duplex, but Pason recommends using the default full duplex setting.

    EDR via a Pason DHC, SideKick, or UJB: 1. Ensure that the DHC, SideKick, or UJB is powered on. 2. Secure the WITS to RS232, 6 ft. cable (CBLASS390) to the WITS Device port on the Hazardous Area WITS Interface Assembly (COMM087). Secure the female DB-9 end to the WITS device.

  • Page 13: Testing Wits Connections

    If connecting to a SideKick, ensure that the port you’re using is set to Auto (Port Info > Port Setup from the SideKick’s main screen). If connecting to a UJB, ensure the port is set to WITS (Setup Ports > Change to WITS from the UJB local interface). This requires UJB firware version 11 or higher.

  • Page 14: Setting Up Wits In The Edr

    Set up on UJB If connecting to a UJB, ensure the port is set to WITS. This requires UJB firmware version 11 or higher. Select Setup Ports > Change to WITS from the UJB local interface. Then select either WITS 9600 or WITS 19200.

  • Page 15: Setting Up The Edr Comm Port

    EDR Comm Port list. In these cases, you do not need to set up a comm port. To determine if WITS is working in these setups, check the WITS monitor, check the EDR for WITS traces sent by the third-party device, or check the third-party device for WITS values sent by the EDR.

  • Page 16: Determining The Assigned Comm Port For Wits Connections Via Toolpush Connection Box Or Network Panel

    The EDR uses several comm ports for communicating, so you need to determine which port the EDR uses for WITS. Follow the steps below to find the assigned port if you connected the WITS device to the TPC via a COMM022: 1.

  • Page 17: Setting The Send/Receive Mode

    Send/Receive Options for WITS Connections via Toolpush Connection Box or Network Panel If you connected the WITS device to one of these panels with a COMM022, you can set the EDR to send WITS data, to receive WITS data, or to send and receive WITS data.

  • Page 18: Figure 9: Comm Port Setup Screen

    The Comm Port Setup screen opens. Figure 9: Comm Port Setup screen 2. Select the assigned WITS comm port as described in Determining the Assigned Comm Port on page 16. 3. Click either Toggle Next or Toggle Prev to turn off the Auto setting and toggle through the additional protocols.

    WITS codes in Default Pason WITS Codes on page 32). If you need the EDR to receive a code not listed in the table, you need to set up a custom WITS code as described in Configuring Custom WITS in the EDR on page 24.
  • Page 20 Element Function WITS In All On the RMPC, use this tab to set up incoming WITS codes for all Pason computers connected to WITS devices. WITS Out RMPC On the RMPC, use this tab to set up WITS codes being sent to devices connected to the RMPC.
  • Page 21 Clears all your selections and returns the settings to the defaults. Table 1: WITS setup screen elements In addition to choosing individual WITS codes, the EDR provides the option of using preconfigured Full WITS or Half WITS settings to determine which WITS codes it sends.
  • Page 22 7. If desired, you can click in a code’s row, and enter a new WITS code for that row. Any standard WITS code that you have changed displays a Reset button. If you enter a WITS code that is already in use, click the Reset button to change back to the default Pason WITS code.

  • Page 23: Selecting Pason Traces For The Edr To Send

    Selecting Pason Traces for the EDR to Send Starting in EDR version 14.12, the WITS setup screen includes a feature that enables you to send Pason trace data using WITS. Use this feature to send Pason traces that aren't included with the standard WITS codes.

  • Page 24: Configuring Custom Wits In The Edr

    If you need to send or receive data not listed in the table of Default Pason WITS Codes on page 32, you must set up a custom WITS code. Once a custom WITS code is set up, the EDR can receive it from any connected WITS device, but you need to follow the...

    WITS code. Ensure that this code is different from the existing WITS codes. If the code you enter conflicts with a current EDR WITS code, the EDR highlights your entry in red and does not allow you to save your settings.
  • Page 26 Shelf life is an important selection for time sensitive data. The EDR displays the last received WITS value until the sender transmits a new value, or until it reaches the end of the shelf life period. WITS data with a long shelf life can be misleading if users don’t know the data’s age.

  • Page 27: Selecting Custom Wits Codes To Send

    2. Enter the custom four digit WITS code you want to use to send the value. Use a code that’s different from the existing WITS codes. If the code you enter conflicts with a current EDR WITS code, the EDR highlights your entry in red and does not allow you to save your settings.

    If a Pason technician needs to troubleshoot WITS communications using CommEngine log files, they can use the Port and Port Name details to identify the CommEngine to work on. Each WITS device is represented by its own CommEngine process. WITS CommEngine troubleshooting information is available to Pason personnel in KBase 1125 Debugging WITS Data Using CommEngine Log Files.
