This product can translate RS-232 signal to RS-485 signal, and extend the communicate range to 1.2 kilometer, no need for external power source. This Transverter use a unique ‘RS-232’ charge pump, no need to initialize the RS-232 serial port and it can start work. It ha a unique zero time delay and auto transmitting-receiving, it can control data flow direction. It can provide a point to point and point to multi-point net work.
