摘要:
A master station has a master-station transmission circuit that extracts a serial monitor signal so as to convert a control data signal into monitor data by changing a duty ratio of negative and positive voltage-level periods, converting the control signal into a serial pulsing voltage signal, transmitting a monitor data signal that is superimposed on the serial pulsing voltage signal, and detecting the presence or absence of a signal of a current that flows during the negative and positive voltage-level periods. A plurality of slave stations respectively have a slave-station transmission circuit that identifies a duty ratio of the positive and negative voltage-level periods relative to each serial pulsing voltage signal, that extracts a control data signal so as to output the data to a controllable unit of the slave station.
