CAN FD Trigger (Controller Area Network, CAN with Flexible Data-Rate)

CAN / CAN FD trigger supports frame types, error checks, and Clause Trigger ID / Data patterns. The physical layer is differential (CAN_H / CAN_L).

Wrong Data Rate or channel mode prevents triggers. TravelBus offers a dedicated CAN port. See Settings and Clause Trigger.
