DB9 RS232 to RS422 RS485 Serial COM Converter Adapter, Integrated Connector, FullDuplex 232485/422 Transceiver for Industrial LongDistance Serial Communication Data Transmission

This compact DB9 integrated serial converter adapter achieves bidirectional signal conversion between RS232 COM port and differential RS422 / RS485 interfaces. It supports fullduplex RS232 to RS422 communication as well as halfduplex RS485 mode to satisfy diverse industrial serial connection requirements.

Features allinone DB9 connector form factor for direct plugin installation without additional enclosure. Pure hardware signal conversion, no driver or software configuration required. Internal filter and surgeproof circuits restrain electromagnetic disturbance and voltage surge, maintaining stable data transmission under harsh industrial conditions.

It greatly extends serial transmission distance comparing with original RS232 signal. Compatible with most industrial hardware equipped with standard serial port, such as PLCs, inverters, controllers, measuring instruments and serial sensors. Widely used for equipment debugging, onsite data collection, factory automation and longrange serial communication applications. Universally works with devices featuring standard DB9 RS232 COM port, not limited to specific brands.
