feet away from the work area. The ex•tend•it line offers solutions for noise, space and
security concerns, data center control, information distribution, conference room presen-
tation, and school and corporate training environments.

move from one monitor to another to access different computers.And, it saves money

CONNECTING AND OPERATING THE 2X1 DVI SL SWITCHER
How to Connect the SL Switcher to your devices
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 SL 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 SL 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 5VDC power supply into the SL Switcher.
How to Operate the SL Switcher
1- Use the front panel push button to switch between sources.
2- Use the RMT-2IR wireless remote control to remotely switch between sources.
3- Use the optional RMT-2 wired remote control to remotely toggle between sources.
Operation Notes
When turning on or rebooting your computers, the SL 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 loose your picture when switch from source 1 to source 2 or vice-versa you
will require a DVI Detective.
The equalization knobs can be used to balance out signal noise resulting from
long cables for better picture quality.
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. Connect
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.

3. Insert the battery, hold the battery so that you can see the positive side facing up. The
side that is not marked must be facing down.

multiple buttons simultaneously and do NOT press buttons rapidly. These actions will
