Product Description

The MWE485-TDM is a enhanced 3-end isolation RS232 to RS485/422 interface converter. It can achieve bidirectional data conversion between serial ports, and the converter can automatically detect the baud rate of the serial port and be convenient to use, the data flow will not loss even if the baud rate of the device changes. It uses I/O circuit to automatically control the direction of data flow, no need the handshake signal settings, ensuring compliance with existing communication software and interface hardware. It supports hot plug and can operate stably even in temperature environments ranging from -40 ℃ to +85 ℃. It can be widely used in indoor and outdoor serial field-bus 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;

-2500V photoelectric isolation, external power supply DC+5V or DC9～30V;

-Industrial-grade design.
