CAN / RS232 Ports / USB
The VB20SL is equipped with a CAN Bus interface, a RS232 serial port and an USB port. The RS232 port or USB is used for all communication between the
VBOX and laptop PC. The USB or RS232 ports are able to transmit live data from the VBOX to the PC for viewing and performing real-time tests.
Note only the USB port is used for firmware upgrading
The CAN Bus port is available in either the socket labelled CAN or the socket labelled Serial. This CAN port has two functions known as Internal and External
mode.
Internal Mode:
This mode should be selected when Racelogic input modules are connected to t
he 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.
See the section ‘Setup’ in the VBOX software manual.
The Socket labelled CAN also contains a secondary RS232 port for direct connections to the GPS engine for Local DGPS correction connection.
