Simple Transparent transmission
The transparent transmission means that whatever is transferred, our device plays the role of a channel and sends data to the target without modification. On-site monitoring equipment sends data to Serial Device Servers transparent data transmission terminal by itself port, the terminal CUP receives data by serial port and package data.
Various parameter setting method
Software Settings
Download settings software, search related Serial Device Servers in the LAN through the serial port server IP, name, MAC address, or the version number. Then set the parameters you need, otherwise, keep the default.
Web-page Settings
- Open your browser and enter the default IP address of the Serial Device Servers.
- Open the login page of Serial Server, Enter the username and password (default admin).
- After setting parameter, Click Save and Restart, then setting will take effect.
Serial AT commands Settings
User can set parameter by module itself without going through another computer to configure. This setting method is used in the following situation: user have to configure IP address and destination IP address on site. AT command can meet the demand. After MCU connects serial server module by TTL (UART), MCU can configure setting by AT command.

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]
