Change or configure the interface (port) settings from within FlexLogger in the Interface Settings dialog.

This feature is available only as part of a complete FlexLogger license. Refer to FlexLogger Editions for more information.

CAN interfaces are software representations of physical ports. Complete the following steps to adjust the port settings.
  1. Enable Termination, if necessary.
    Improperly configured Termination schemes might result in bus error frames or missed data. Refer to High-Speed CAN Cable Termination or Low-Speed CAN Cable Termination for more information on proper termination.
  2. Enable the Listen only option, if necessary.
    Note If you have multiple nodes connected to an ECU, the Listen only option can prevent acknowledgment activity on lines that do not require monitoring to interfere with the activity of lines being monitored. Also, if you are receiving data but the transmitting node is not receiving the acknowledgment, the Listen only option can help prevent a bus load condition that could result in a fault. If you only have two nodes on the bus, Listen only mode should be turned off to allow acknowledgments and prevent bus errors.
  3. Use the Baud rate pull-down menu to select an applicable baud rate to all clusters, if necessary.
    Notice The port will use the baud rate that is defined by the selected database. A Baud rate set to an unsupported value might result in bus error frames or missed data.
  4. (Optional) After the Baud rate is selected, the option to Enable raw frame logging is enabled. Selecting this option will allow FlexLogger to log data without associating the port to a database.
  5. (FD baud rate) Select the applicable I/O Mode to enable the FD baud rate pull-down menu, if necessary. The following table explains the available I/O Modes.
    Table 30. I/O Mode Options for CAN Baud Rate
    Option Description
    CAN The default CAN 2.0 standard I/O mode as defined in ISO 11898-1:2003. A fixed baud rate is used for transfer. The payload length is limited to 8 bytes.
    CAN FD (FD baud rate enabled) The CAN FD mode as specified in the CAN with Flexible Data-Rate specification, version 1.0. Payload lengths up to 64 are allowed, but are transmitted at a single fixed baud rate.
    CAN FD + BRS (FD baud rate enabled) The CAN FD as specified in the CAN with Flexible Data-Rate specification, version 1.0, with the optional Baud Rate Switching enabled. The same payload lengths as CAN FD mode are allowed; additionally, the data portion of the CAN frame is transferred at a different (higher) baud rate.
  6. Select the FD baud rate from the pull-down menu to select an applicable fast data baud rate for all clusters.
