Product Description

MWE485-C can convert a 3 wires (RX,TX,GND) RS-232 serial port signal to a 2 wires semi duplex RS-485 signal or to a 4 wires full duplex RS-422 signal without external power supply. The main function is to realize the bidirectional mutual conversion between RS-232 signal and RS-422/485 signal. The series products are powered by serial port stealing or external power supply, which has small size, long distance, stable performance and other characteristics. At the same time, the series of products are easy to install and meet the needs of industrial field serial port data conversion, and are widely used in intelligent power management, intelligent traffic bayonet, water conservancy monitoring, industrial automation and other systems.

Features and Benefits

-RS-485 two-wire half-duplex communication, RS-422 four-wire full duplex;

-Equipped with integrated industrial wiring terminal, standard DB9-hole serial port;

-Unique serial port protection circuit, which can be hot-swappable when power is on;

-Built-in intelligent module, automatic identification of RS-485 signal flow direction, without CTS flow control;

-Signal line 600W/ms anti-lightning protection and 15KV anti-static protection;

-Transparent transmission, self-adapting baud rate, no need to change user protocol;

-Industrial-grade design, optimized imported components, all surface mount technology.
