Data Transmission Test of serial to Ethernet converter USR-N540

This article is about the data transmission test of serial to Ethernet converter USR-N540. Data transmission test 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.


2. The right side is Network Settings: TCP Client, IP address:, port number: 23, 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-N540’ COM->USR-N540 Ethernet port->PC Network;

Data from network to serial is: PC Network->N540’ Ethernet port->N540 COM-> PC’s COM.


The below picture is about the data transmission test of serial to Ethernet converter USR-N540  for your reference:
