SAE J1939 datalink is a high-speed network for machines that operate at a 250K baud rate. J1939 is capable of supporting control, information sharing, diagnostics, multiplexing and proprietary communications. The J1939 (physical layer) datalink uses a differential line driver circuit and allows a maximum bus length of 40 meters. The network can have a maximum of 30 node connections at any given time.

We design and build the following J1939 bus interfaces:
