INTRODUCTION

Congratulations on your purchase of the 8 x1 DVI-DL KVM 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 8x1 DVI KVM DL/SL Switcher

The rack-mountable Gefen 8x1 dual link/single link DVI KVM 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 8x1 DVI KVM DL/SL Switcher shares one

DVI display with up to eight 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 8x1 DVI KVM DL/SL Switcher’s output. Up

to eight DVI video sources connect to the switcher’s DVI inputs using included

high quality DVI 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-

8IR remote control, RS-232 control, or the input selector push button on the front

panel of the switcher.

OPERATION NOTES

READ THESE NOTES BEFORE INSTALLING OR

OPERATING THE GEFEN 8X1 DVI KVM DL/SL SWITCHER

• The 8x1 DVI KVM DL/SL Switcher will take any of up to eight (8) DVI dual-

link or single-link resolution inputs and switch them, one at a time, to a DVI

output device such as a display/monitor or projector. Resolutions can be up

to 3840x2400.

• The 8x1 DVI KVM DL/SL Switcher is housed in a metal box for better RF

shielding.

• Computers must be turned on one at a time and the switcher must

be selected to the computer that is booting up. This is so that monitor

information (EDID) can be transmitted from the display to each computer.

After one computer completes the startup process, you can boot up the

second computer and repeat the process with the remaining computers.

This can be avoided with the use of the LOCAL EDID mode (page 11)

that will constantly supply each computer with an EDID. In this scenario, a

stored EDID, or user uploaded EDID, is supplied to each input for use by

the connected source device. Then, each computer can boot up in any order

and at anytime, regardless of which computer the switch is selected to.
