PURPOSE:To decrease the number of the connection circuits by combining several kinds of frequency signals and then transmitting the control signal transmitted between the master and slave units in the form of the time-division multiplication information. CONSTITUTION:First, various kinds of information to be given to slave unit 10 are produced by supplying the output of detection signal generation part 6 to the CPU at the side of master unit 9. Based on this control signal, control signal generation part 5 is controlled to produce several kinds of control signals arranged in the time- division way. These control signals are then transmitted to the side of slave unit 10 via transmission circuit 3, connection circuit 2 and signal line 1. While at unit 10, these signals are supplied to the CPU via circuit 2 and reception circuit 4 to judge the information and then control proper load 7 via load driving circuit 8. At the same time, part 6 of unit 10 detects the state of load 7 for input to the CPU. Based on the input signal, the CPU produces the control signal for monitor to transmit it to the side of master unit 9. Then load 7 is operated by the CPU of the side of unit 9 and via circuit 8. |
