INTRODUCTION
Congratulations on your purchase of the Gefen 4x1 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 4x1 DVI Switcher
The rack-mountable Gefen 4x1 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 4x1 DVI Switcher shares one DVI
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 SWITCHER
How to Connect the 4x1 DVI Switcher to your devices:
1. Connect the 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 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 4x1 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 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.
How to Operate the 4x1 DVI Switcher:
4. Use the RMT-4IR 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
