Generate software triggers for a Basler USB camera from within a LabView VI

Dear all,

 

I'm writing acquisition software for a Basler USB camera (model #: Basler acA1920-155um). [Link to a programmer's manual below, though maybe not the most recent one]: http://mlab.no/blog/wp-content/uploads/2009/06/basler_pylon_prog_guide_and_api_ref.pdf


So far I've been successful acquiring images and setting camera attributes with IMAQdx in LabView. (To do this, I've been looking through the above manual and the NI-MAX XML file for the camera to get the attribute names and values, then using IMAQdx property nodes to set the attribute name and value.) When testing the camera in NI-MAX I'm able to generate software triggers for the camera with the 'Execute' button below (see screenshot below). The software triggers also work in the native Basler Pylon viewer program as well.

I'm not exactly sure what the 'Execute' button does (I guess it's a call to something in the Basler API), though perhaps there are some suggestions in the above manual.

Can you describe how to run the 'Execute software trigger' from within a LabView VI as well?

 

Thanks for your help!
