Function Structure

Work mode

TCP Server

Serial to Ethernet servers 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 TCP clients via USR-N520.

TCP client mode

Serial to Ethernet servers USR-N520 initiates a TCP connection to the set IP address.
If the connection fails, USR-N520 will keep trying to reconnect until it succeeds.
Once the connection is successful, the data will be transparently
transmitted between PC and serial device in bi-directional.

UDP mode

Serial to Ethernet servers USR-N520 will transmit serial data from serial device to
target network device by UDP connection.
USR-N520 will listen to port and transmit all received data to serial device.

httpsD Client

Supports https Client mode which can transmit serial data to the https server in https 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

Virtual Com Software

Features

Socket B function

Serial to Ethernet servers USR-N520 supports the secondary network link, which can send data to two servers.
Used for data backup, remote diagnosis, and other requirements.

Serial & Network Heartbeat Packet

Network Heartbeat Packet: Serial server maintains the normal connection with the server by sending heartbeat
packet regularly. Serial Heartbeat Packet: Serial server informs serial device is active, can be applied in
actively catching sensor data.

Support modbus gateway

More function

Customize webpage, Synchronized baud rate,
net printing, registration package, cloud

Application

[ Unattended Weighing System]

Connect serial to Ethernet servers USR-N520 to barrier gate and it can realize remote
control of barrier gate by Ethernet in control center.
