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.


  • 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
