Abstract
A slave control device receives a communication signal from a master control device, and controls loads according to the received communication signal. A modulator superimposes the communication signal from the master control device on power source lines, and a demodulator demodulates the communication signal superimposed on the power source lines and supplies the demodulated communication signal to the slave control device. The modulator is provided on power source lines on a battery side, and the demodulator is provided on the power source lines on a load side. The modulator superimposes the communication signal on the power source lines which are on a side closer to the loads with respect to the modulator among the power source lines.
