8 ports device serverUSR-N668

8-port RS232/422/485 serial device servers 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
Serial port switching among RS232/RS485/RS422

New and industrial design which saves the port space of device, prevent from ash and collision and promote the safety while operating.
Works at RS232 port by default. Please adjust the dial code to corresponding position when you use RS485/422 serial port.
Every serial port can choose mode freely, don’t worry about unified mode for all serial ports.
