industrial 8 serial port ethernet converter USR-N668:Serial port switching among RS232/RS485/RS422

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.

industrial 8 serial port ethernet converter USR-N668: TCP Server

Work mode

TCP Server

Serial server device USR-N668 listens on the setting port and waits for a TCP client connection.
The data which the serial ports sent out transparently transmit to all connected client via serial device USR-N668.

industrial 8 serial port ethernet converter USR-N668: TCP client mode

TCP client mode

The serial converter N668 initiates 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.

industrial 8 serial port ethernet converter USR-N668: UDP mode

UDP mode

Serial server device USR-N668 sent the data to designated IP /Port. If the connection fails,
USR-N668 will keep trying to reconnect until it succeeds. Meanwhile, USR-N668 listens the port and forwards
all data received to serial device.
