INTRODUCTION
Congratulations on your purchase of the 4x1 DVI DL Switcher. Your complete satisfaction is very important to us.
Gefen’s line of KVM (Keyboard Video & Mouse), DVI, ADC, 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. The ex•tend•it line offers 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 fi nest 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 four dual link DVI
& USB 2.0 equipped computers (PC or Mac) - using only one keyboard, display and
mouse. The 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.

RMT4-IR INSTALLATION
1. Remove battery cover from the back of the RMT4-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 RMT4-IR remote by pressing ONLY one button at a time. The indicator light
on the remote will fl ash once each time you press a button. WARNING: Do not press
multiple buttons simultaneously and do NOT press buttons rapidly. These actions will
cause the remote to reset and steps 1-4 will have to be repeated.
Note: The RMT4-IR ships with two batteries. One battery is required for operation, the
second battery is complimentary.
How to Operate the IR Extender Eye (optional)
Plug in the IR extender eye to the extender port on the back of the switcher. As soon as
the IR extender eye is plugged in you can extend your IR signal. The IR extender eye
does not come included in the package.
Optional RMT-4 wired remote control
and IR extender eye.

DIP SWITCH GUIDE
if you are experiencing Infrared interference, you can change the IR code on the
Remote and the 4x1 DVI DL Switcher itself.
To change the IR code on the RMT4-IR, simply remove the battery cover and fi nd the 2
dip switches just above the batteries. These switches correspond to a set of switches
on the 4x1 DVI DL Switcher.
To change the IR code on the 4x1 DVI DL Switcher, look under the unit and fi nd a blank
silver sticker. Beneath this sticker is a bank of 4 dip switches. The fi rst 2 switches
(labelled 1 and 2) correspond to the 2 switches found on the RMT4-IR remote control.
The following are the 4 Infrared channels possible for both the RMT4-IR and the
4x1 DVI DL Switcher. The dip switches on both the remote and the switcher itself must
match in order to be operational.

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 the 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 fl ip 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 DL 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 you switch between sources you will need a DVI
Detective.
To switch between Dual Link and Single Link sources, a Single Link cable (sold
separately) must be used for each Single Link source connected to the switcher.
