08 - VBOX II CAN / RS232 / USB


VBOX II units are equipped with a CAN bus interface, an RS232 serial socket and an USB socket. Either of the SERIAL or USB sockets can be used for all communication between the VBOX and a PC, including configuration of the VBOX and to transmit live data from the VBOX to the PC for viewing and performing real-time tests.

Note, however, that only the USB socket can be used for upgrading the VBOX’s firmware.


The CAN Bus port is available in either the socket labelled CAN or the socket labelled Serial. This CAN port has three functions, CAN Input in VCI mode, CAN Input in Racelogic Modules Mode (Internal Mode) and CAN output in Racelogic Modules Mode (External Mode).

VCI Mode:

This mode should be selected if you wish to log incoming CAN data from external modules from other manufacturers, or a Racelogic Micro Input Module. Note in VCI mode no CAN output or connection to any other Racelogic modules is possible.

Racelogic Modules mode

This mode should be selected when Racelogic modules are connected to the VBOX or VBOX CAN output is required. Depending upon configuration, VBOX Tools software should be set as follows:

  • Internal Mode:  This mode should be selected when Racelogic input modules are connected to the VBOX. In this mode the CAN id’s and Baud rate are non configurable.
  • External Mode: This CAN mode should be used when a VBOX CAN data output is to be used by an external CAN device such as a Data acquisition system. In this mode the attributes of the CAN output stream are configurable by the user in VBOX Tools

The Socket labelled CAN also contains a secondary RS232 port for direct connections to the GPS engine. These can be used to provide the GPS engine with Local DGPS correction messages, or occasionally for fault-finding under the instruction of a Racelogic employee.
