Issue Details

  • I'm trying to change the attributes of my camera from NI MAX, but when I save the changes, close MAX, and reopen it again, the attributes are the same as the beginning.
  • I'm trying to use multiple of same cameras, and when I try to change the attribute of specific camera, the change applies to other cameras. 

Solution

To work with camera devices, NI MAX takes information from two files:

  • The .icd file that has all the attributes of the camera.
  • The .iid file that saves the name of the .icd file and additional information from the device, like the serial number.

You have to check that the name of the .icd file appears correctly in the .iid file. If the .iid file stores a different name, NI MAX will not be able to find the correct .icd file, and it will not change or update the attributes.

Also, check if there is .icd and .iid file for all cameras used. If the files for specific device are missing, create by making a copy of other existing files and updating information such as serial number. 

Additional Information

For example, with the .icd file names as  'AVT Pike F145C (#000A4701100A3031).icd', a correct .iid files will show the next information: 


A wrong .iid will show the next information:
