Issue Details

My camera is getting hot. I tested with the below program, and I found when IMAQdx Configure Grab.vi is executed, the camera LED shows it starts working, but I do not perform the IMAQdx Grab in my program, why did my camera start?

Solution

IMAQdx Configure Grab.vi function including start camera action, if you want to configure the camera without starting the camera, try IMAQdx Start Acquisition VI or IMAQdx Read Attributes VI. When you want to start the grab function, have the start API before it and the camera should start after the start API is executed.
For example:

You can replace the IMAQdx Read Attributes.vi with IMAQdx Configuration Acquisition.vi.
