ABSTRACT:
A transmitting receiving circuit having two different blocks, one for transmitting, and one for receiving, the transmitting block relying on an inverter and a differential transmitter, while the receiving block has a differential receiver, four optocouplers, two inverters, a voltage regulator and two resistors, the galvanic discoupling being carried out between the parts corresponding to the transmission and reception by telefeeding the differential receiver from the board where the signal is transmitted, the optocouplers separating the receiving block parts fed from the board where the transmitting-receiving circuit is installed, from the parts fed from the module transmitting the signal, the output thereof being optically disconnected from the distant end.
