CAN connection. Use the CANJST4 (Code 101-0198) cable for connecting CAN devices. This new 4 pin port and cable provides not
only the CAN connection, but also a protected 12V power supply and ground for powering the CAN devices. The power supply is protected
by a self-resetting fuse rated at 3A continuous.
