  • 2 Ports Serial RS232/RS485/RS422 to Ethernet Converter USR-N520

    USR-N520 is a double serial device server, which can realise transparent transmission between TCP/UDP data package and RS232/RS485/RS422 interface. The device has unique functions such as network printing, UserModbus multi-host polling and watchdog mechanism. USR-N520 is based on ARM processor and it is internally integrated with TCP/IP protocThe user can easily realise embedded device networking.

    Note: This kit includes the AU power adapter, DB9 cable, and connectors.

    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

    1. Open your browser and enter the default IP address of the Serial Device Servers.
    2. Open the login page of Serial Server, Enter the username 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.
