INTRODUCTION

Congratulations on your purchase of the 8x8 DVI KVM Dual Link Matrix. Your
complete satisfaction is very important to us.

GefenPRO

In the realm of video distribution, certain features are invaluable in a commercial
or broadcast environment. Accommodations such as a built-in power supply
and fl at black rack-mount enclosures set GefenPRO apart from our traditional
products. Complex distribution units allow for professional DVI, 3G-SDI, and
HDMI signals to be routed and converted easily and seamlessly, while being
backed up by a renowned and dependable technical support team. Gefen invites
you to explore the GefenPRO product line and hopes that you fi nd the solution
that fi ts your needs.

The GefenPRO 8x8 DVI KVM Dual Link Matrix

Easily switch eight cross-platform DVI Dual Link computers to eight DVI Dual
Link displays with our 8x8 DVI KVM Dual Link Matrix. This product provides a
simple, reliable and highly effective method of creating multiple computer work­stations, with each workstation capable of accessing any one of the computers
or sources at any time by remote control. Eight stations can be set up locally or
extended with a Gefen extender. When used with computers, USB and Audio
matrix control signals follow the DVI Dual Link input for organized signal routing.

How It Works

The 8x8 DVI KVM Dual Link Matrix has eight Dual Link DVI inputs and eight Dual
Link DVI outputs. Simply connect eight computers’ DVI Dual Link video ports
to the Matrix’s inputs, then connect eight DVI Dual Link displays to the Matrix’s
outputs. USB keyboard and mouse signals and analog audio, once connected,
follow the selected DVI Dual Link input for each computer.
