INTRODUCTION

Congratulations on your purchase of the DVI•2500HD. Your complete satisfaction
is very important to us.

Gefen

Gefen delivers innovative, progressive computer and electronics add-on solutions
that harness integration, extension, distribution and conversion technologies.
Gefen’s reliable, plug-and-play products supplement cross-platform computer
systems, professional audio/video environments and HDTV systems of all sizes
with hard-working solutions that are easy to implement and simple to operate.

The Gefen DVI•2500HD

The DVI•2500HD uses 4 fi bers to extend Dual Link DVI display up to 6,600 feet
away from your source. Dual link DVI describes the use of all 24 pins of the DVI
(digital visual interface) connector to achieve super high resolutions.

How It Works

The DVI•2500HD Sender unit sits next to your computer. A short video
cable supplied with the DVI•2500HD system connects the DVI source to the
DVI•2500HD Sender unit. The DVI•2500HD Receiver unit sits next to your DVI
display and plugs into the DVI display’s Dual-Link DVI port. One CAT-5 cable and
a LC fi ber optic cable (4-strand) connects the Sender and the Receiver units to
each other.

Note:

The CAT5 cable is for the transmission of DDC/EDID (video timing, resolution)
information, the Hot-plug signal and DC power. The fi ber cable carries the video
picture information.

DVI Extension can be:

• up to 500m (1640 feet) over Multi-mode fi ber using Virtual DDC.

• up to 2 km (6,600 feet) over Single-mode fi ber using Virtual DDC.

• up to 100m (330ft) with direct DDC using CAT5.
