C lick Listening, Open COM port .
The module will connect to the server and show the module IP and port.
5 . Now you can transfer data from PC RS232 to Ethernet.
You can use other TCP UDP test software and COM port test software as you like.

4 . Setup as the follow pictures, you need to notice COM port, bond rate and work mode of PC, then click
Activate

Activate .
5 . After Activate click, a Virtual COM port COM2 , will be created, COM2 will receive data from TCP IP socket,
and send data to COM2 will convert to TCPIP socket data to remote Equipment .
If create failed, please notice to see error notice and log, when use Virtual COM Port, you should close other
software who use the same TCPIP port.
The success picture as follow:

At this point, you can use your equipment as an ordinary serial port, and operate of local virtual serial port will
converted to operation of the remote module RS 232. The figure is show send data between the two serial port .
