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

CONNECTING & OPERATING THE 4X1 DVI KVM SWITCHER
How to Connect the 4x1 DVI KVM Switcher to your devices:
1. Connect your computers’ DVI, USB, and Audio sources to the 4x1 DVI KVM
Switcher inputs using the supplied cables.
2. Connect your USB and audio devices to the USB and audio outputs using the
supplied cables.
3. Connect your DVI-compliant display to the DVI output of the 4x1 DVI KVM
Switcher using a user-supplied DVI cable.
4. Connect the included 5V DC power supply to the Switcher by connecting its
5V DC power supply tip into the receptacle in the rear of the unit, then plug it
into the wall.
5. Turn on the DVI display or projector first, then the DVI video sources/
computers.
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.
How to Operate the 4x1 DVI KVM Switcher:
1. Use the RMT-4IR remote control to remotely switch between DVI video
sources.
2. Alternatively, use the front panel selector buttons.

OPERATION NOTES & TROUBLESHOOTING
USB
If your USB stops functioning correctly, you can manually re-intialize the
USB hub in the switch by pushing twice on the channel select button that
corresponds with the channel that the switcher is pointed at, on the front of
the unit. This will cause the channel selected LED to blink once letting you
know that the internal USB hub has been re-initialized. To have the USB
re-initialize automatically every time you switch, look under the 4x1 DVI
Switcher and locate the blank sticker. Peel it off to reveal a bank of four dip
switches. Find the dip switch labeled “4” and flip it to the ON position. Now
every time you switch the hub will re-initialize itself.
Video
When turning on or rebooting your computers, the 4x1 DVI KVM Switcher
must be selected to the computer that is booting until the computer
completes the boot cycle. This step can be eliminated using the Gefen DVI
Detective. If you lose your picture when you switch between sources you will
need a DVI Detective.
