INTRODUCTION
Congratulations on your purchase of the 8x1 DVI 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 Switcher
The rack-mountable Gefen 8x1 single-link DVI Switcher offers an economical
solution by eliminating the need to purchase many displays for each DVI source
in a studio or lab situation. A plug-and-play solution, the 8x1 DVI Switcher shares
one DVI display with up to eight computers or other DVI video sources, saving
space on your desktop. The source computer is selected using the included IR
remote control or through RS-232 control.
How It Works
The DVI monitor is connected to the switcher’s output. Up to eight DVI 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 computer’s video signal
appears on the shared monitor. Video sources 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 SWITCHER
• The 8x1 DVI Switcher will take any of up to eight (8) DVI 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 1920x1200.
• The 8x1 DVI Switcher is housed in a metal box for better RF shielding.
• Computers must be turned on one at a time and during this process the 8x1
DVI Switcher must be selected to the computer that is currently booting up.
This is so that monitor information (EDID) can be transmitted properly from
the display to each computer. Please see page 6 for further information.

CONNECTING AND OPERATING THE 8X1 DVI SWITCHER
How to Connect the 8x1 DVI Switcher to your devices:
1. Connect the supplied DVI cables from the DVI sources into the 8x1 DVI
Switcher’s Inputs.
2. Connect the cable from your display (monitor or projector) into the DVI Out
of the 8x1 DVI Switcher.
3. Connect the included 5V power supply, then plug it into the wall. Turn on the
DVI display or projector first, then the video sources. Turn on the 8x1 DVI
Switcher by screwing its 5V DC power supply tip into the receptacle in the
rear of the chassis.
Note: Computers must be turned on one at a time and the switcher must
be selected to the computer that is currently booting up. This is so that
monitor information (EDID) is correctly 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.
How to Operate the 8x1 DVI Switcher:
4. Use the RMT-8IR remote control to remotely switch between DVI video
sources.
5. Alternatively, use a RS-232 control system such as a PC with
communications software (for example, Microsoft’s Hyperterminaltm) or an
automated control system such as Crestron.tm
