Abstract
An intermediate station transmits a supervisory signal sent form a given controlled device to a controlled device associate with the given device as a control signal. An intermediate-station input unit extracts a supervisory signal, which is a current signal superimposed on a signal transmitted through a data signal line, in every clock cycle. An intermediate-station output unit obtains the supervisory signal in every clock cycle, and outputs a control signal, which is a pulse-width-modulated voltage signal, onto the data signal line in the same clock cycle in which the supervisory signal has been extracted.
