Congratulations on your purchase of the Gefen 2x1 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 2x1 DVI KVM Switcher
The Gefen 2x1 DVI KVM Switcher easily and reliably switches between any
combination of two DVI and USB 2.0 equipped computers (PC or Mac) - using only
one keyboard, monitor, and a mouse. It saves space - there is no need to work on
a desk crowded with double monitors, keyboards, and mouse devices. It saves
time - there is no need to move from one monitor to another to access different
computers. It also saves money - there is no need to purchase additional monitors,
mouse devices, and keyboards. The 2x1 DVI KVM Switcher allows you to choose
between a PC or Mac keyboard/video/mouse combination.
How It Works
Connect a single-link DVI display and USB 2.0 keyboard/mouse to the 2x1 DVI
KVM Switcher's outputs. Connect both computers' DVI, USB, and audio ports to
the Switcher's inputs using the supplied cables. Select the computer to control
using the select button on the front panel. A contact closure remote control may
also be used. The Switcher is compatible with both Macintosh and PC keyboards,
mice, and monitors.

CONNECTING AND OPERATING THE 2x1 DVI KVM SWITCHER
How to Connect the 2x1 DVI KVM Switcher to your devices
(Please refer to the Panel Descriptions diagram on the next page as needed)
1- Connect the supplied cables from your first computer into the DVI In 1, USB In
1, and Audio In 1 connection in the back of the 2x1 DVI KVM Switcher.
2- Connect the supplied cables from your second computer into the DVI In 2,
USB In 2, and Audio In 2 connection in the back of the 2x1 DVI KVM Switcher.
3- Connect the monitor to the DVI Out connection.
4- Connect your USB devices (e.g. keyboard, mouse) into the USB Out.
5- Connect your speakers to the Audio Out.
6- Plug the 5V DC power supply into the 2x1 DVI KVM Switcher.
How to Operate the 2x1 DVI KVM Switcher
1- Use the front panel push button to switch between sources, or use the optional
RMT-2 wired remote control to remotely toggle between sources.
Operation Notes
When turning on or rebooting your computers, the 2x1 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 switching from source 1 to source 2 or vice-versa
you will require a DVI Detective.
If you are experiencing USB dropouts try using the switcher just as a USB hub
by only connecting the USB cables from your computers to the switcher. Con-
nect your devices to the USB out portion of the switcher and connect your display
to your computer directly. Start your computer up and try switching. If your USB
devices do come up normally then you will need a DVI Detective to negotiate the
video/USB signals for faster switching. If they do not come up normally, then you
will need to call tech support.
