IMAQdx Error 0xBFF69002, "Invalid Parameter"

[DKFF]

Hello,

I'm using USB3 Basler acA3088-57 uc camera with NI-Vision Development 2016. I see the camera from the MAX but when I try to access the camera, I get "Invalid Parameter" error. I completely uninstall and reinstall whole NI software (LabVIEW, Vision Acq SW, Vision Dev Module, etc) but I still see the same error. I can access and grab image from "Integrated Camera". Is there any recommendation how to fix this? Is this camera not supported by NI? This works fine if I use Pylon (Basler's camera application).

Appreciate the help.

Thanks.

Hello,

Sorry to hear you are running into an issue.

This camera definitely should be supported, and I am surprised you are seeing such an error. Unfortunately, this type of situation is very difficult to troubleshoot just by asking you to try things.

Please contact support about this and it should be escalated up to the Vision Acquisition Software team. We will have to work with you to install some debugging tools on your system and do a remote session to get a better idea of what's going on and see if we can find a work around for you until the issue is resolved.

Thanks,

Katie (SW Engineer, Vision Acquisition Software)

Im my experience, that error occurs when you a camera with "hidden" (vendor) parameters and access them with vendor-specific tools. (This is often necessary thanks to NIs stupid "let's hide the IP settings philosophy, but that's another topic).

The trick is to modify / delete the camera description files that are transferred from the camera upon "first contact". There are 3 relevant files: The iid (linking "cam4" with the settings) and icd file (stores the settings) in C:\Users\Public\Documents\National Instruments\NI-IMAQdx\Data\ ... and more importantly, the related xml files in C:\Users\Public\Documents\National Instruments\NI-IMAQdx\Data\XML
As a first step, I would delete those 3 files and try again. As a second step, I would search for that parameter adress in the error message, and check what it is and change that in Pylon. ..

I deleted those description files, reinstalled but still the same issue. I completed uninstall LV2016, removed all NI files and installed LV2017 - fresh install and now it's working. I must had some files left in somewhere when I did LV2016 uninstall.

Thanks for the help.
