Introduction :
EOT-N520 is a dual serial device server, which can provide transparent transmission between TCP/UDP data package and
RS232/RS485/RS422 interface. The device has unique functions such as
network printing,Modbus multi-host polling and watchdog mechanism.
EOT-N520 is based on ARM processor and it is internally integrated with
TCP/IP protocol. User can easily realize embedded device networking. Use the outside DIP Switches to easily configure between 232 ,485 and 422 Protocols.
Features
- Cortex-M4 kernel,industrial working temperature range and TCPIP protocol stack.

- Two channel serial communication indicator: TX/RX
- Support DC adapter and 5.08-2 terminal power supply
- Support UDP broadcast function
Simple Transparent transmission
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 inter the default IP address of the Serial Device Servers.
- Open the login page of Serial Server, Enter the user name 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.
Example Applications :
- Industrial data transmission, industrial automation
- security and protection monitoring, public security
- Smart home, power control, environmental monitoring, intelligent agriculture
- Door check on work attendance system, POS system, rice selling system
- Building automation system, power monitoring, self-service banking system, telecom machine room monitoring
