Bộ chuyển đổi Port-powered RS-232 sang RS-485 3Onedata TLC485/9


Support bidirectional data conversion between 1 RS-232 serial port and 1 RS-485 serial port 

Unique port-power technology, no need for external power supply 

Low power consumption, equal to that of normal light-emitting diodes in static operation, can be truly called passive

Automatic serial port signal rate detection, support 0~115200bps serial port baud rate

Adopt automatic data flow control technology, which can detect and control the direction of data transmission

Compact size and easy installation


TLC485 series are pocket RS-232 to RS-485 interface converters with high cost-effectiveness, which can implement bidirectional data conversion between serial port RS-232 and RS-485 and need no external power supply. This series have two types of products and provide a RS-232 and a RS-485 serial port that support optional DB9 and DB25 connection, which can meet the requirement of different scenes.

The RS-232 port of TLC485 series could connect to PC directly and obtain power from PC serial port via TXD, RTS and DTR signal line. RS-485 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.
