The current camera file that shows up next to the Channel under Measurement & Automation Explorer (MAX) is actually set by lines in the interface file (.iid
) for your specific interface. If your interface name is img0, then this file will be named img0.iid
and will be located at <Users>\Public\Documents\National Instruments\NI-IMAQdx\Data
(for Windows XP and older, the directory is <Documents and Settings>\All Users\Documents\National Instruments\NI-IMAQ\data
In this file, there is a line for each channel followed by the name of the camera file (.icd
) used by that channel. These camera files are contained in the same directory as the interface file (see path above).
Note: If the camera file (.icd
) is not located at the same path as the .iid
file, you will need to either move it to the same path or use the full .icd
path for the CameraFile
You can parse the camera file as a text file and replace the portion of text in the quotation marks following the respective channel with the name and file extension of the new file to use. See Change Camera File Programmatically
for an example of how to programmatically change your camera file.
