ABOUT YOUR INTERFACE 2
There are a great variety of computers and computer
video cards on the market today. There are also
numerous 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 these display
devices. The DA1910SX computer video interface
that you have just purchased from ALTINEX is
designed to resolve this incompatibility.
Interface Capabilities
The DA1910SX is a high resolution computer video
interface designed to allow the connections of VGA,
SVGA, XGA, UXGA, MAC, SUN, SGI, and other
analog computer video sources to scan rate
compatible monitors, projectors, and LCD displays.
The DA1910SX amplifies video signals and converts
sync to various formats. It does not change the
scan-rate or the resolution of the video signal. The
computer and projector must be scan rate
compatible with each other.
The DA1910SX input is VGA compatible. The
DA1910SX provides two fully buffered outputs: a
main output on 5 BNC connectors which provides
RGBHV, RGBS, or RGsB, and a pass-through 15
pin HD monitor output. The monitor output is
typically used to transmit signals to a local monitor. If
the input signal format is RGBS or RGBHV, the main
output may be RGBHV, RGBS, or RGsB. If the input
signal is RGSB, the output must be RGsB. The
DA1910SX is not designed to separate sync from
green.
