This Driver ID module is required for the IMSA Michelin Pilot Challenge and Prototype Challenge Series. The module reads the driver helmet resistor value using a voltage divider circuit. The voltage value is then correlated to a Driver ID number. It then transmits this value via CAN to the X2 transponder for the IMSA timing and scoring system. Basic CAN diagnostics allow the module to report if there is no CAN bus traffic detected for proper operation.
