CAN Communications
The CK-M12 transmits 1 CAN message that provides the status of each button and digital
input, and receives 1 message to configure the indicating ring color for each button and the
overall keypad brightness. The default baud rate is 1,000 kbps, however, other baud rates and
IDs can be achieved through custom configuration by Bosch Motorsport.
Notice!
The brightness value MUST be sent to see any indicator feedback. Colors 9 to 15 will not
be visible when using brightness value 1.
