CAN

Updated on Mar 4, 2026

The CAN menu is where you can export dbc files, set the CAN baud rate, set the output rate, set the CAN termination and configure and enable full bus logging for the CAN FD ports.

VBOX4ADAS v1.1_Setup_CAN_BusLoading

In the top right-hand corner of the CAN menu, you will see this Bus loading graphic.

It will display the current load on the CAN bus, so you can see the load applied to the bus as you add channels. We recommend a maximum load of 70%. If the CAN bus loading exceeds the recommended 70%, the CAN bus may become unstable and samples may be lost. You can reduce the bus load by increasing the baud rate or reducing the number of output IDs.

The available baud rate options are:

  • 1 Mbit/s
  • 500 kbit/s
  • 250 kbit/s
  • 125 kbit/s
