Sometimes, camera firmware is the problem. Sometimes, the camera XML file is the problem. Sometimes, the way that IMAQdx tries to force settings onto the camera is the problem.
Things to try:
1. Check with the manufacturer, and ask if new firmware is available for the camera. If the firmware cannot be updated by the end user, you will need to get a Returm Merchandise Authorization number, and send the camera in for the upgrade.
2. Edit the XML file that was downloaded from the camera, and remove all references to CameraAttributes::AutoFunction::AutoTargetGrayValue. Do not alter, or remove the zip file that resides in the same location as the XML. If you do, IMAQdx will request a fresh copy from the camera, and overwritew your changes. You can find the XML file in C:\Users\Public\Documents\National Instruments\NI-IMAQdx\Data\XML
3. Edit the camera .icd file in C:\Users\Public\Documents\National Instruments\NI-IMAQdx\Data, and remove the reference to CameraAttributes::AutoFunction::AutoTargetGrayValue.
