Product Description

Port-powered bidirectional RS-232 to RS-422 converter


TLC422 series are pocket RS-232 to RS-422 interface converters with high cost-effectiveness, which can implement bidirectional data conversion between serial port RS-232 and RS-422 and need no external power supply. This series have two types of products and provide a RS-232 and a RS-422 serial port that support optional DB9 and DB25 connection, which can meet the requirement of different scenes.


The RS-232 port of TLC422 series could connect to PC directly and obtain power from PC serial port via TXD, RTS and DTR signal line. RS-422 serial port DB9M is equipped with pluggable terminal blocks which is easy and convenient to use and can be widely used in point-to-point communication, industrial distributed system, POS cash register, bank, insurance, security, canteen food selling system, transportation toll system, industrial distributed control, various PLC, data watt-hour meter, gas meter, etc.
