How to change the gain of IMAQ PCI 1407

Hi All
I am using LabView 6.1 and IMAQ 2.5.1 to run a system that capture images of aggregates while moving in x and Y direction. A video enhancement controller is used. I am attempting to bypass this video controller and not to use it. I know that I can do that if an additional gain is available on the video frame graber card (IMAQ PCI 1407). The problem that I have no idea how this can be done? is it possible to do that through adjusting the volts of white and black for the camera properties taht can be accessed through measurements and auto mation\Devices and interfaces? or Do I need to develope a new vi ? or is there a vi available at NI website as an example that can be used directly? Hope if there will be a detailed procedure if
a vi need to be developed.
