ABOUT YOUR INTERFACE

There are varieties of computers and computer video cards on the market today. There are also several data monitors and large screen data projectors. When displaying a computer image on a large screen data projector or on a large screen monitor, it often becomes clear that some computers are not always compatible with certain display devices. The VA6835FC is a computer video interface designed to resolve this incompatibility.

The VA6835FC is a dual output computer Video Interface. It is designed to interface a single VGA/ SVGA/ XGA/ UXGA/ MAC/ SUN or SGI computer video source to two scan-rate compatible presentation monitors or data projectors.

It is important to understand the general capabilities of this interface. The VA6835FC does not change the scan-rate or the resolutions of the video signal so the source (computer) and display (projector or monitor) must be scan-rate compatible. The VA6835FC simply converts a computer video signal to a pre-selected analog format or separates the sync signal from the green signal on output 1 if the input signal is RGsB.

The VA6835FC is a state-of-the art piece of equipment with an exceptional combination of compact size, advanced features, and very competitive pricing.
