![]() It is compatible with current communication software and hardware, no need to set the previous working mode which based on RS-232. This converter is with built-in zero delay auto receiving and transmitting conversion and unique I/O circuit auto control data flow direction without any handshake signal (RTS, DTR) there is no need jumper wire setting for full duplex (RS-422) and half duplex (RS-485) mode, plug & play. It adopts unique “RS-232” charge pump technology to drive the system, and gains power without initializing RS-232 serial port. The transmission distance of RS-232 communication can be extended to 1.2km. It converts RS-232 signals into balanced differential RS-485 or RS-422(UT-203A) RS-422(UT-202D) signals. For communication between PC with different standard serial port and external equipment’s or intelligent instruments, standard serial conversion is necessary. ![]()
