ABSTRACT:
A communications channel interconnects first and second controllers positioned in the tractor and trailer, respectively, and includes inductive coupling coils carried by an electrical connector so that the connector is preferably compatible with the industry standard J560 connector. The communications channel also preferably includes first and second sections of twisted pair cable extending between respective controllers and coils. The connector includes disengageable first and second connector portions to facilitate disconnecting the tractor and the trailer. A pair of controllers communicates over the communications channel via respective modems. In addition, each of the controllers includes digital and analog interfaces for receiving and outputting signals to monitor and control operation of various subsystems of the tractor/trailer combination.
