ABOUT YOUR INTERFACE

2

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.
