The CAN menu is where you can export dbc files, set the CAN baud rate, set the output rate and CAN termination and see an overview of the unit's CAN ports.
In the top right corner of the CAN menu, you will see a Bus loading graphic.
This graphic will display the current load on the CAN bus, so that you can see the load you apply 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
Vehicle CAN bus (VCI) baud rate
The baud rate sets the bit rate of the CAN messages (not the frequency at which the messages are sent). VBOX 3i units have four baud rate options – 1 Mbit/s, 500 kbit/s, 250 kbit/s and 125 kbit/s. The default setting is 500 Kbit/s as most light vehicles use that baud rate.

Custom Baud Rate
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
This setting controls the CAN output update rate for the purpose of resolving bandwidth limitation issues. The available update rates are:
- 100 Hz
- 50 Hz
- 20 Hz
- 10 Hz
- 5 Hz
- 1 Hz
Termination
Ticking the Termination CAN Port box will add 120-ohm resistance to the CAN bus connection.
Note: If you add or remove termination on the CAN port, you must power-cycle the VBOX after writing the settings to the unit.

Xtd
Tick the respective Xtd boxes for the identifiers you wish to extend from the standard 11-bit format to the extended 29-bit format.
If it is unticked, the CAN identifier type will be standard 11 bit. The standard identifier type allows 2048 different CAN message identifiers or message “names”. The extended identifier type allows 436207616 different CAN message identifiers. The identifier type should be set to match the CAN data logging equipment.

You can output channel data from the Racelogic CAN bus (i.e. Racelogic modules such as TC8) on the isolated customer VCI bus. You can configure output data (in VBOX Setup) by using channels from the available channels dropdown list, and configure the identifier as required.
The VBOX unit can output up to 8 user-configured CAN messages, and 16 CAN channels over the customer VCI bus.
