The Camera Settings area of the Settings dialog box enables user to retrieve settings
from the camera so that they can be stored with the configuration and applied each

The Live tab on the RV2 interface provides an AutoOnce button that tells the camera

no direct control of gain and white balance on the RV2 interface, so if you want to
manipulate those values you will have to adjust them in the Settings dialog and
upload the configuration to the RV2 to apply those camera settings. See "Saving
Configurations" on page 8-31, for more information on uploading the configuration.
