MWE485-TDM can convert a RS232 serial port signal to three wires high speed semi duplex RS485 or a four wires full duplex RS422 signal, with 2500V optical isolation between the signal and the power. 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.
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.
