As the development of PC, USB port starts to replace most of the low speed external ports from old PC. In industrial field, most of the devices or equipments are still using RS-232 interface. In this situation, we need to use USB to RS-232 converter to complete the data transmission between PC and RS-232 equipment.

UT-2003B is a universal USB to RS-232 converter without external power. It complies with USB, RS-232 standards; it converts single side USB signal to RS-232 of UART; RS-232 adopts DB9 male connector. This converter is with built-in zero delay auto receiving and transmitting conversion, and unique I/O circuit auto control data flow direction, plug & play. It is compatible with current communication software and hardware.

UT-2003B provides connection for point to point communication. The baud rate can be 300-921.6Kbps. The power and data flow indicators indicate the working status.
