The configuration files are located in C:\Program Files\National Instruments\NI-IMAQ for IEEE-1394\Data. The attributes you configure in MAX show up in the camera file. You can programmatically change the attributes in LabVIEW. Check out the shipping example Grab and Attributes Setup. You can find the example by going to Help>>Find Examples. Then browse by Directory Structure. Then open the IMAQ folder and then the IMAQ1394 examples.llb. There you'll see the Grab and Attributes Setup.vi.
