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

• 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

1. Open your browser and inter the default IP address of the Serial Device Servers.
2. Open the login page of Serial Server, Enter the user name and password (default admin).
3. 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
