INTRODUCTION

Congratulations on your purchase of the 4x1 DVI-DL KVM DL/SL Switcher. 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 4x1 DVI KVM DL/SL Switcher

The rack-mountable Gefen 4x1 dual link/single link DVI KVM DL/SL Switcher
offers an economical solution by eliminating the need to purchase many displays
for each computer in a studio or lab situation. A plug-and-play solution that
supports both Macintosh and IBM-PC computers, the 4x1 DVI KVM DL/SL
Switcher shares one DVI display with up to four computers or other DVI video
sources. A single USB 2.0 port, keyboard & mouse ports, and an analog audio
jack are also switched. The switcher saves space on your desktop by eliminating
a crowded workspace full of DVI monitors, keyboards & mice, and USB and
audio cables. Switching of DVI sources is easy and reliable.

How It Works

The DVI monitor is connected to the 4x1 DVI KVM DL/SL Switcher’s output.
Up to four DVI video/USB/Audio sources connect to the switcher’s inputs using
included high quality DVI, USB and Audio cables. The included power supply is
connected to the switcher via the locking power plug and then to a power outlet.
The currently selected DVI video signal appears on the shared monitor. DVI
Video sources (and optionally keyboards & mice, USB and audio cables) are
selected/switched using the RMT-4IR remote control, RS-232 control, or the input
selector push button on the front panel of the switcher.
