CAN

This page contains an overview of the features and settings in the CAN Menu in VBOX Setup connected to VBOX 4 ADAS.

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.

Bus Loading

VBOX4ADAS_CAN_BusLoading_150px.png

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.

Baud Rate
VBOX4ADAS_CAN_Settings_CAN_BaudRateOptions.png

The baud rate sets the bit rate of the CAN messages (not the frequency at which the messages are sent). 

The default setting is 500 Kbit/s as most light vehicles use that baud rate. 

The available baud rate options are:

  • 1 Mbit/s
  • 500 kbit/s
  • 250 kbit/s
  • 125 kbit/s 
  • Custom
Custom Baud Rate

VBOX4ADAS_CAN_Settings_CAN_CustomBaudRate.png

If you wish to use another baud rate than the specific baud rate settings, you can select the Custom option and click the Edit button. This will open a window where you can set your own custom baud rate.   

Output Rate
VBOX4ADAS_CAN_Settings_CAN_OutdateRateOptions.png

This setting controls the CAN output update rate for the purpose of resolving bandwidth limitation issues.

The available output rates are:

  • 100 Hz
  • 50 Hz
  • 20 Hz
  • 10 Hz
  • 5 Hz
  • 1 Hz
Termination
