INTRODUCTION
Congratulations on your purchase of the 8x1 DVI 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 8x1 DVI DL/SL Switcher
The rack-mountable Gefen 8x1 DVI dual-link/single-link 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 DL/
SL Switcher shares one dual-link 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.

CONNECTING AND OPERATING THE 8X1 DVI DL/SL
How to Connect the 8x1 DVI DL/SL 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 DL/SL Switcher and turn on the display.
3. Turn on the DVI display or projector.
4. Connect the included 5V DC power supply to the Switcher by screwing its
locking power tip into the receptacle in the rear of the unit. Plug the power
cord into a free wall socket.
5. Turn on the computers.
Note: For the first-time power-up sequence, please make sure that the display
device is turned on and connected to the 8x1 DVI DL/SL Switcher before
applying power to the Switcher. The reason for this procedure is that EDID
information will only be copied from the display device to DVI sources upon
power-up. If power is applied to the Switcher before the display device is
connected and powered up, the Switcher’s last recorded EDID from previous
activity will be used.
How to Operate the 8x1 DVI DL/SL Switcher:
6. Use the RMT-8IR remote control to remotely switch between DVI video
sources.
7. 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
