RS-232 to RS-485 converter UT-201 is compatible with the recommended standards of RS-232C, RS-485

RS-232 to RS-485 converter UT-201 isompatible with the recommended standards of RS-232C, RS-485. No external power but adopts a particular RS-232 charge pump to drive the system. The unique I/O circuit of the internal zero delay auto transceiver contained in the converter controls the data stream direction automatically without any handshaking signal (for example RTS, DTR etc). interface converter can convert the single-ended RS-232 signal into balance differenced RS-485 signal. Through a DB9 female connector RS-232 interface is connected to other interfaces compatible with RS-232C standard, and for RS-485 interfaces a DB9 male connector is to be used for connection.
