CAN

Updated on Mar 13, 2026

In the CAN menu in VBOX Setup, connected to a VBOX 3iS Dual Antenna RTK, you can configure the CAN input and output settings and select transmitted identifiers.

Configure the CAN input/output baud rates and termination and export the channel information as a .dbc file.
 

CAN Settings-default

Input - The software has four baud rate input values: 1000 kbit/s, 500 kbit/s, 250 kbit/s or 125 kbit/s.

This is used to input wheel speed signals. When you are using this, you must make sure that the settings must match the vehicle's CAN bus.
