USR Industrial Ethernet to 4 Port Serial

USR-N540 is an Industrial Serial to Ethernet Converter to realize bi-directional transparent transmission between RS232/RS485/RS422 and network with function of modbus gateway. It has 4 serial ports, each one can select RS232/ RS485/RS422 Hardware Watchdog, keep to work stable Modbus RTU -TCP, Customized webpage, and websocket serial ports which can work simultaneously.



The USR-N54010 has five different working modes.

TCP Server

Serial server device USR-N540 listens on the setting port and waits for a TCP client connection. The data which the serial ports sent out transparently transmit to all connected client via serial device USR-N540.

TCP Client Mode

The serial converter USR-N540 initiates a TCP lint to the set IP address. If the connection fails, USR-N540 will keep trying to reconnect until it succeeds. Once the link is successful, the data will be transparently transmitted between PC and serial device in bi-directional.

UDP Mode

Serial server device USR-N540 sent the data to designated IP /Port. If the connection fails, USR-N540 will keep trying to reconnect until it succeeds. Meanwhile, USR-N540 listens the port and forwards all data received to serial device.

HTTPD Client

Support serial data transmitted to designed server in HTTPD way

WebSocket

Supports WebSocket Sever，Built Websocket link with devices by Websocket of webpage, HTML5 Data transmission between built-in webpage and serial port in bi-directional, Custom webpage and websocket are acceptable, Achieves the functions of displaying data in real-time
