MULTIPLEX TRANSMISSION EQUIPMENT

摘要

PURPOSE:To reduce the number of connector connection electrodes between an instrument panel harness and the other wire harness at lower cost and to improve the workability for automobile assembling. CONSTITUTION:With respect to a cowl node 40 and an air conditioning amplifier node 50 connected to the wire harness other than the instrument panel harness and an automobile air conditioning switch node 20 connected to the instrument panel harness for signal multiplex communication, only the air conditioning switch node is connected to the instrument panel harness, and signals for air conditioning load control are multiplexed and communicated through a transmission line between this node and the air conditioning amplifier node, and plural signals for meter load control are received from the cowl node or the like through the signal line to drive and control the loads for meter like warning lamps/indicator lamps 61 connected to an output circuit 25 through plural electric wirings like electric wires 14.
