Abstract
In an in-vehicle network, a master device and a plurality of slave devices communicate with each other. A plurality of semiconductor relays for supplying power to the corresponding slave devices is provided for each of the plurality of slave devices in the master device. IDs corresponding to the plurality of semiconductor relays are stored in a flash ROM of the master device. The master device transmits the corresponding ID each time the semiconductor relays are turned on by sequentially turning on the semiconductor relays. The plurality of slave devices set the ID received after power supply as its own ID.
