Incorrect Hardware Options in MAX (VISION)

[jmaslek]

Hi.  I am currently using LV 2013 with the August 2015 Vision.  My camera is https://www.flir.com/products/chameleon3-usb3/ which works perfectly fine when using the grab function.

My issue is that when I want to set it to an external trigger (I have it to GPIO3 = Line 3), the property node gives an error saying the 'Trigger Source' is out of range (setting it to 3). 

When I look at the Camera Attributes in MAX, it shows I only have Software and Line 0.  I am curious as to what would cause this difference.  I am using IMAQdx 15.0.0.

I've struggled with a Flir camera (a Grasshopper model), which works fine with the vendor's Driver (which is not compatible with IMAQdx), but when I try to implement some of the functions (like triggering with GPIO3) listed in the Manual using even very low-level IMAQdx functions, it doesn't always work.  It isn't clear to me whether the problem is that the Camera doesn't (quite) follow the GenICam standard or whether there's something flakey about it's implementation.  I will say that before I gave up, I was actually "down in the weeds" and trying to work at the Register level of the camera, and still no joy.

I even tried Visual Studio and C++, but after LabVIEW, I didn't have the patience to go back to such a complex text-based programming environment ...

I ended up finding in the Advanced Camera Settings in MAX something that allowed me to declare the desired pin as an input instead of an output and that has currently worked for me.
