Data transmission test for RS485 serial to Ethernet converter is based on the default parameters, please refer to the following steps:

1.Open test software “USR-TCP232-Test.exe”, and do hardware connection according to Chapter 1.1 Hardware Testing Environment

Click https://www.usriot.com/support/downloads/usr-tcp-test-testing-software.html to download "USR-TCP232-Test.exe".

2.The right side is Network Settings: TCP Server, IP address: 192.168.0.201, port number: 8324, click “Connect” to build TCP connection

The left side is Serial Settings: Baud Rate: 115200, Parity/Data bit/Stop bit: None/8/1,

Click “Open” to enable the COM.

Then we can test data transmission between COM and network.

Data from serial to network is: PC’ COM->USR-DR302’ COM->USR-DR302 Ethernet port->PC Network;

Data from network to serial is: PC Network->DR302’ Ethernet port->DR302 COM-> PC’s COM.
