Serial to Ethernet Converter, 2 ports
USR-N520 is a 2 Ports Serial to Ethernet Converter, which can realize transparent transmission between TCP/UDP data package and RS232/RS485/RS422 interface.
- 2 serial ports, RS232 RS485 RS422 three-in-one
- Voltage range of 5~36v DC
- Modbus RTU to Modbus TCP, CTS/RTS, XON/XOFF
- 2 serial port can works simultaneously
Work mode
TCP Server
Serial server device USR-N520 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-N520 initiates a TCP lint to the set IP address.
If the connection fails, USR-N520 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 device server will transmit serial data from serial device to target network device by UDP connection. Serial device server will listen to port and transmit all received data to serial device.
HTTPD Client
Supports HTTP Client mode which can transmit serial data to the HTTP server in HTTP format(GET/POST).
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
