Abstract (en)
A road vehicle electrical system includes a digitally controlled multiplex system whereby load devices destributed around the vehicle are controlled by signals from a transmitter connected to a plurality of receivers each controlling a group of load control devices. The transmitter produces a pulse train divider into digital words each word including one set of bits identifying an address of a receiver and another set identifying an instruction code for the loads controlled by that receiver and determined by switches operable by the driver. Each receiver includes an address identification circuit and a storage device for the instruction code. A receiver acts on an instruction code only if the same instruction code is received in two successive cycles of the transmitter.
