Read commands sent with a different VI.


I have a software from a company to modify the temperature of a heater through USB. I have no access to the Block Diagram of it, neither to the commands.


Is there any possibility (VISA function for instance) to know the commands that the software sends to change/read the temperature?


Thank you very much!

Please Check for SCPI Commands (Used to Control the heater temperature),should be available with the Manufacturer (Programming Manual).

You can also use NI I/O Trace Capture to monitor what commands have been sent and received, and do some reverse engineering.
