BNC Connectors
Many home theater projec-
tors do not have an HD-15
connector, in which case
you can use an adapter
cable to convert from VGA
to the BNC connectors
used on the projector.
These adapter cables are readily available
through most home theater retailers and
have a VGA connector on one end and
BNC connectors on the other. The BNC
end of the cable will usually have 5
connectors (labeled R, G, B, Hsync, and
Vsync), although not all will necessarily
be needed for every display. Please refer
to your display’s specifications to deter-
mine which input signals it requires.
If your display device accepts Y-Pb-Pr
Component video, then you will not need
the H and V lines since these sync signals
are actually part of the information in
the ‘Y’ signal.
If your display device requires YUV/S or
RGB/S, then this is Composite Sync, which
is sent on the H (white/gray) line.
Displays that require RGBHV or YUVHV
will require all 5 BNC connectors. Hsync is
sent on the white/gray wire, and Vsync is
sent on the yellow/black wire.

DVI Digital Video Input
The DVI digital
video connector
is used on many
of the newer digital TVs and is similar in
functionality to the analog VGA connec-
tor except that the video signal is trans-
mitted digitally from the iScan Ultra to
the display device. This provides the
highest possible quality video image from
the iScan Ultra to the display. For more
