These control modules allow vehicle manufacturers to make the most of a mechanical platform or extend the life of a system. Rugged CAN Control Modules make it easy to convert analog machine data into digital data and to broadcast that data on the J1939 CAN data bus for availability by any system.

How do CAN bus modules communicate?

How do CAN bus modules communicate? CAN bus uses two dedicated wires for communication. The wires are called CAN high and CAN low. … When data bits are being transmitted, the CAN high line goes to 3.75V and the CAN low drops to 1.25V, thereby generating a 2.5V differential between the lines.

CAN wiring system?

The CAN bus system enables each ECU to communicate with all other ECUs – without complex dedicated wiring. Specifically, an ECU can prepare and broadcast information (e.g. sensor data) via the CAN bus (consisting of two wires, CAN low and CAN high).
