Serial to Ethernet Converter USR-N668 Introduction of 8-port RS232/422/485 Serial Device Servers
Serial to Ethernet Converter USR-N668 is a 8-port RS232/422/485 serial device servers.
Features of USR-N668
8-port RS-232/422/485 serial device servers.
Power supply accepts wide voltage input range AC 85-265V.
Support TCP server/client, UDP server/client, https client, Virtual COM.
Support Modbus RTU to Modbus TCP.
Support flow control CTS/RTS, XON/XOFF.
Support 8 software selectable RS-232, RS-485/422 RJ45 serial port to 1 10/100Base-T(X) self-adaptive Ethernet interface, rack-mount.
Configuration via Web Server page, AT commands, and Windows Utility.
Work mode
TCP Server
Serial server devices USR-N668 listen on the setting port and wait for a TCP client connection.
The data which the serial ports sent out transparently transmit to all connected client via serial device USR-N668.
TCP Client
Serial device servers USR-N668 initiate a TCP lint to the set IP address.
If the connection fails, N668 will keep trying to reconnect until it succeeds.
Once the link is successful, the data will be transparently transmitted between PC and serial device in bi-directional.
UDP Mode
Serial server devices USR-N668 sent the data to designated IP /Port. If the connection fails, USR-N668 will keep trying to reconnect until it succeeds.
USR-N668 listen the port and forward all data received to serial device.
https D Client
Support serial data transmitted to designed server in https D way.
