You can carry out the bidirectional between the serial port and the Ethernet port.

Communication procedures are as follows:

1) Open the testing software” USR TCP232 Test.exe ””，connected hardware

2) The default mode of operation is TCP Server, f irst port serial port monitor 20001 port So choose TCP client mode at the network setup end of the software ,IP:192.168.0.7,target port 20001,then click the connect. The serial baud

rate is 115200, The serial port parameter is set to None/8/1,chick open.

3) Send data for test, the data flow form serial port to Net is: PC serial port -->668 serial port -->668 Ethernet port -->PC

network; the data flow form Net to serial port is: PC network -->668 Ethernet port -->668 serial port -->PC serial p ort.

The specific demo is shown below.
