Product Name:8-port RS232/422/485 Serial Device Servers
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.
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.
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.
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. Meanwhile, USR-N668 listen the port and forward
all data received to serial device.
Support serial data transmitted to designed server in httpsD way
