How Do I Monitor UART Data Over the RS232 Bus with a USB Protocol Analyzer?

Question from the Customer:
Our project is to monitor UART data for several hours. We want to integrate that feature in a software product. For that we need an API (C/C++). We have the Beagle USB 480 Protocol Analyzer – and would like to use it to monitor the RS232 bus and capture the UART data. Is there any way we can do that?

Response from Technical Support:
Thanks for your question! Using the Beagle Software API you can use your Beagle USB 480 analyzer directly with RS232 but you will need one more small device - an inexpensive RS232 converter, serial to USB.

As shown below, place the RS232 converter between the target device and the Target Device power of the Beagle analyzer.

For your setup, use the Beagle API Software to create the script that you need. Using API software, in addition to monitoring the RS232 data, you can store all the data you need on a hard drive. Our API software is compatible with many languages including C and C++. We also provide API software examples that you can use as is or modify as needed.

For information about the API software, please refer to API Documentation in the Beagle Protocol Analyzer User Manual. There is also a section for USB specific API software.
