A multiplex information handling system comprises a series of electronic processing units each comprising a receiver and a transmitter and each having an electronic address in binary form. The units are joined by a coaxial cable which in operation carries power along the cable sheath and information signals in binary form along the central core. Each unit controls the operational state of various items of equipment, for example of a vehicle, and receives and transmits signals controlling and representing those states. All units receive all transmitted signals, the correct signal being directed to the correct item of equipment by producing the correct unit address at the head of each information signal. The transmitters transmit repeatedly and sequentially, all transmitters being inhibited from transmitting except the transmitter transmitting at the time. The information concerning the operational states of the various items of equipment is therefor continually updated. |
