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.

1, and Audio In 1 connection in the back of the DVI 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 DVI Switcher.

3. Connect the monitor to the DVI Out connection.

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

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.

Remote Channel 1:

Remote Channel 2:

Remote Channel 3:

Remote Channel 4:

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).
