This page contains information about the settings available in the Digital IO Setup menu in the LabSat 4 Web Server connected to LabSat 4 Record & Replay variants.

Model Limitations

The Digital IO Setup menu will not be available for LabSat 4 Lite models. 

In the Digital IO Setup menu, you can configure the 4 external data channels to LabSat 4. These channels can be set up to record/replay CAN, RS232, and/or digital signals. You can also configure arbitrated CAN and RS232 recording/replay.

Sample Rate

This section is where you can adjust the sample rate for the digital signals you want to capture in your scenario. By reducing the sample rate, the recorded data will take less space in the available recording rate.

The sample rate options will depend on the maximum bandwidth set on the frequency setup menu. 

The Time accuracy and Max baud rate will update as you adjust the sample rate.

Note: Configured digital channels will be added in addition to the LabSat channels and will contribute to the Record rate usage. You can go to the Frequency Setup menu to check that it is within the required limitations. The digital channels will be the grey block in the Record rate usage bar.

In the table below the diagram, you can set the signal source picking from the available channels:

  • CAN 1

After selecting a signal source, the Web Server will provide pin information for the record input and the replay output and the pin diagram for the Expansion Connector port and the Expansion Connector will update to illustrate the connections.
