Abstract

PURPOSE:To make a circuit small, by using an element which drops the voltage without changing a circuit impedance in a DC loop of two-line transmission line, in a communication system superimposing pulse signals on a power supply current from a master to slave devices. CONSTITUTION:The power supply voltage of a power supply device 1 of the master device is sufficiently higher than the breakdown voltage of Zener diodes 111-212 of pulse transmission circuits 11, 21 and pulse reception circuits 12, 22, the Zener diodes are ON even if photocouplers 113-214 are all OFF, and the power supply current is fed to the power supply regulator 2 at the terminal. In the signal transmission from the master to the slave device, the voltage drop at the tri-state of both photocouplers 113, 114 ON, one OFF and one ON, and both ON is different from each other, and the bipolar signal corresponding the intermediate voltage as ''0'' and other voltage in two-state as ''1'' is transmitted. In the slave device, the voltage across the terminal resistor 221 of the reception circuit 22 is detected for reception. The transmission from the slave device is made the same method as reception in time division.
