A purpose 

 RS-422 repeater optical isolation for the signals to extend the transmission distance of RS-422 can also be used to increase the RS-422 signal drive capability (with a load capacity). Boston Electronics zero time delay relay apparatus intelligent conversion transceiver, without control signal. YG422C, YG422TC Photoelectric isolated RS-422 (full duplex) optical repeater can also be used as isolated RS-485 (half-duplex) / RS-422 (full duplex) converter, is only able to support full-duplex on multi-machine communication RS-422 repeater. 

 Second, installation and performance 

 RS-422 communication line in series with a RS-422 repeater may be extended 1.2Km (9600bps pm). Incorporates a RS-422 repeater can make RS-422's with a load capacity increased to 128. Optical repeaters separated generally support the highest communication rate 9600bps, 9600bps, please specifically stated more than you can.
