Congratulations on your purchase of the Gefen 2x1 DVI DL Switcher. Your complete
satisfaction is very important to us.
Gefen’s line of KVM (Keyboard Video & Mouse), DVI, USB, switches, extenders,
converters and hubs is designed to make computer use more comfortable, more
productive and less expensive. KVM switches allow access to multiple computers
from a single keyboard, while the extenders give the user control over a computer
up to 330 feet away from the work area.
Gefen products offer solutions for noise, space and security concerns, data center
control, information distribution, conference room presentation, and school and
corporate training environments.
Our Commitment
Gefen will always offer the finest quality product at the best possible price. Included
in that price is a lifetime of free support from a team of outstanding engineers.
Now you can switch easily and reliably between any combination of two dual link
DVI & USB 2.0 equipped computers (PC or Mac) - using only one keyboard, display
and mouse. The 2X1 DL cross platform switcher saves space - there’s no need to
work on a desk crowded with double displays, keyboards and mouse devices. It
saves time - there’s no need to move from one monitor to another to access different
computers. And, it saves money - there’s no need to purchase additional displays,
mouse devices, keyboards etc.

2x1 DVI DL OPERATION NOTES

Operation Notes
When turning on or rebooting your computers, the DVI DL Switcher must be select-
ed to the computer that is booting until the computer completes the boot cycle. This
step can be eliminated using the Gefen DVI Detective, which stores the displays
EDID.
If you loose your picture when switch from source 1 to source 2 or vice-versa you
will need 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. 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.
RMT2-IR INSTALLATION
6
1. Remove battery cover from the back of the RMT2-IR remote.
2. Verify that dip switches 1 & 2 are in the down (OFF) position.
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.
4. Test the RMT2-IR remote by pressing ONLY one button at a time. The indicator
light on the remote will flash once each time you press a button. WARNING:
Do not press multiple buttons simultaneously and do NOT press buttons rap-
idly. These actions will cause the remote to reset and steps 1-4 will have to be
repeated.
Note: The RMT2-IR ships with two batteries. One battery is required for opera-
tion, the second battery is complimentary.

IR CODE CONFLICTS
In the event of IR conflicts, please do the following:
1. Remove the battery cover from the back of the RMT 2-IR remote.
2. Locate the Dip Switches just above the batteries
3. Switch the Dip Switches on the RMT 2-IR to any of the combinations pictured
below.
4. Dip Switches 1 and 2 in the RMT 2-IR correspond with Dip Switches 1 and 2 on
the bottom (underneath a piece of metallic tape) of the 2X1 DVI DL Switcher
respectively. Flip the switches on the outside of the 2x1 DVI DL Switcher to
match the same Remote Channel as the RMT 2-IR. The 2x1 DVI DL Switcher
is now set to a new IR Code.

IR EXTENDER INSTALLATION
How to Connect the IR Extender
(Gefen part #EXT-RMT-EXTIR)
1. Locate the dip switches underneath the switcher, they will be hidden under-
neath a blank silver sticker, and flip dip switch number 4 to the "ON" position.
2. Plug the IR extender into the Remote port on the front of the Switcher Unit (where
the RMT-2 optional wired remote connects on page 3).
You should now be able to switch using the IR Extender (shown on the bottom of page 6
immediately opposite this sentence).
