NOTE: To output DVI, connect directly from the DVI connector of the C2N-
DVP4DI to the display device using a standard DVI-D cable.
NOTE: Maximum length of a DVI cable is 15.4 feet (3 meters).
G. INPUT DVI/RGB (4 female) – allows RGB or DVI video input. Input resolution
from 640 x 480 to 1600 x 1200 (RGB) or 640 x 480 to 1280 x 1024 (DVI) 31.5 to 64
Hz. RGB to DVI adapters (4) for RGB input are supplied.
H. VIDEO INPUT 1-4 (BNC) – allows composite, component or S-video input. You
may have 12 composite video inputs, four S-video inputs, four component video
inputs, or some combination of the three. Each S-video input requires two BNC
connectors, for example, if you are using two S-video inputs, then there are eight
composite video inputs remaining.

S-video inputs must use the same pair of B (Y) and C (C) BNC connectors.
Each component video connection requires a set of three BNC connectors, Y, P
and P , and must use the same group of A, B, and C connectors. Component video
R
can only be 480i. Component video 480p, 720p, and 1080i must be converted to
RGBHV.
NOTE: Composite video is a type of video signal in which all information – the red,
green, and blue (horizontal and vertical sync) signals are mixed together.
NOTE: S-video contains two separate components, luma and chroma (also known
as Y and C signals respectively). The luma signal contains brightness, intensity, and
signal timing information. This signal contains all picture information except for
color. The chroma signal contains only the color information. You can see the
complete black and white image, without the chroma, by only feeding the luma
signal into a monitor.
NOTE: Component video is a method of transferring video information using
multiple, individual signals: luminance (Y), luminance minus blue (PB), and
luminance minus red (PR). Video information is transmitted in individual parts to
prevent errors due to combining and then separating the various parts of the color
video signal. The C2N-DVP4DI supports video standard 480i (480 lines, interlaced).
Component video uses three coaxial video cables with BNC connectors to transfer
the three signal components (refer to the "Appendix" on page 93 for additional
information about component video).
NOTE: RGBS consists of red, green, blue, and a composite sync. RGBHV consists
of red, green, blue, horizontal sync and vertical sync.
NOTE: HDTV and progressive scan component video must be converted to
interlaced RGBHV by a third party device and then applied to the DVI/RGB
connector.
