Abstract

PURPOSE:To transmit plural kinds of transmission signals to the transmission side through one transmission circuit by providing the receiving side of a hot water supplying equipment or the like with a demultiplexer converting a serial signal into a parallel signal and inputting the output of said demultiplexer to respective channels. CONSTITUTION:In the originating side, transmission signals are outputted from respective transmission signal generating means 1 on occasion and inputted to a multiplexer 2 in parallel. In the receiving side, the input signal is converted into an electric signal by a signal converter 5, and the electric signal is inputted to a demodulator 6 through a tri-state buffer 4 in input non-active/output active status. The demodulator 6 demodulates the frequency signal to a binary signal and outputs the binary signal to a demultiplexer 7. Since the binary signal is constituted by arraying respective transmission signal serially with time shearing, the demultiplexer 7 distributes these signals to corresponding channels under control by a time division control circuit 9.
