USR-N520 is 2 serial Port Secure Serial Device Server which can connect RS-232/485 serial devices to the TCP/IP network. It supports bi-directional communication.
The USR-N520 dual serial server is used to realize the bidirectional transparent transmission of data from the serial port to the Ethernet port. Users don't need to worry about the specific details, and the protocol conversion is done inside the server. One side of the serial port realizes the transparent transmission of serial port data, and the other side of the Ethernet port is TCP/IP packets, and the working details can be specified through simple settings, and the two serial ports are independent of each other. You can set it up on a web page inside the server or through the setting software, and you can save it forever at a time.
