INFORMATION
This RS232 interface is exclusively designed for firmware updates, monitoring or adjustments of
CAN parameters.
The RS232 interface enables a direct serial connection between the device and a PC. For test
benches or prototype vehicles in particular, this connection is highly recommended to be able to
execute a firmware update if required!
Should you have any questions regarding this subject, please refer to the BRUSA support at the
