8 Serial Port RS232 RS485 RS422 to Etherent Converter

USR-N668 is a RS232 / RS485 /RS422 to Ethernet server for remote access serial devices.  It can realize data bi-directional transparent transmission between Ethernet and RS232/RS485/RS422 ports.

Variety of serial ports is convenient for customers to use. It also supports AC 220V power supply. Using ARM preofessor makes it low power consumption, fast and more stabliity.

Supports SSL Client.

Working Modes of Serial to Ethernet Converter

1) TCP Client Mode: Client connects Server automatically. User should configure the TCP Server’s IP address and Port.

2) TCP Server Mode: The Max Client number is 8.

3) UDP Client Mode: serial data will be sent to a fix IP address/port which you appointed.

4) UDP Server Mode: serial data will be sent to last source IP/Port

5) SSL Client:  Special Firmware
