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.

Work mode

TCP Server

Serial server devices ST-TCP668I 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 ST-TCP668I.

TCP client mode

Serial device servers ST-TCP668I 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 ST-TCP668I sent the data to designated IP /Port. If the connection fails, ST-TCP668I will keep trying to reconnect until it succeeds. Meanwhile, ST-TCP668I listen the port and forward all data received to serial device.
