CAN Output – VBOX 3iS Single Antenna (v2)

​

The following details the default CAN output from a VBOX 3iS Single Antenna (v2).

This is the Racelogic standard VBOX output, ie. Starting at 0x301. It has a fixed latency of 15 ms.

Data format: Motorola

Channel definitions are available here.

CAN database (.dbc) files can be downloaded here.
