Toggle Between Two Cameras in Vision Processing

[adciv]

I'm basing this on memory, so I may be a little off. The way the VIs select the camera mode is they enumerate all modes and then search for the first one which meets the resolution asked for. I suspect the 30fps modes come first. In order to select a 15fps mode, it may have to be done by explicitly selecting which mode you want to use and sending that to the appropriate IMAQ VI for setting up the camera.
