INTRODUCTION
Congratulations on your purchase of the 4x1 DVI DL 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 DL Switcher
The rack-mountable Gefen 4x1 DVI DL 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 4x1 DVI DL Switcher shares one
dual-link display with up to four 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 four 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-4IR remote control, RS-232 control, or the input selector push button on the
front panel of the switcher.

CONNECTING AND OPERATING THE 4X1 DVI DL SWITCHER
How to Connect the 4x1 DVI DL Switcher to your devices:
1. Connect user supplied DVI cables from the DVI sources into the 4x1 DVI
Switcher’s Inputs.
2. Connect the cable from your display (monitor or projector) into the DVI Out
of the 4x1 DVI DL Switcher.
3. Connect the 5V power supply, then plug it into the wall. Turn on the DVI
display or projector first, then the video sources (computers). Turn on
the 4x1 DVI DL Switcher by screwing its 5V DC power supply tip into the
receptacle in the rear of the chassis.
Note: The Switcher retrieves device resolution and video timing capability
information called EDID from the display and feeds it to all connected input
sources. This mode of operation is called LOCAL EDID mode. It allows
a much faster setup time and improved operational stability since input
sources do not need to individually collect and store EDID on their own.
If some sources do not display correctly, you can individually configure each
input source and/or program custom EDIDs (such as standard compatible
resolutions) into the Switcher, or alternately set each input source to directly
read EDID from the display device (with the Local EDID Mode turned OFF).
These procedures are covered in detail on pages 10-11 along with EDID
concepts in general.
