INTRODUCTION
Congratulations on your purchase of the ex•tend•it Mini DVI Switcher. Your complete
satisfaction is very important to us.
Gefen’s line of DVI switches, extenders, and splitters are designed to make your A/V
equipment use more comfortable, more productive and less expensive.
The Mini DVI Switcher enables effortless DVI video source switching using a single
DVI display. A simple, reliable and economical solution, the Mini DVI Switcher links
any two DVI sources to one DVI display. It completely eliminates the need to
disconnect then reconnect multiple DVI sources, saving time by providing a fundamental tool that brings it all together behind the scenes. When all three devices (the
display plus the two sources) are connected to the Mini DVI Switcher and powered
on, you simply select which source you want to view on the display using the Switcher, the IR remote that comes with it, or any universal remote you program to work
with the Switcher.
Our Commitment
Gefen will always offer the f nest quality product at the best possible price. Included in
that price is a lifetime of support from a team of outstanding engineers.
How It Works
Simply connect your DVI display to the Switcher's display output. Then connect both
DVI sources to the Switcher's inputs using the DVI cables that come with the
Switcher. Once the sources, the Switcher and the display are all powered on and connected, you simply select which source you want to view.

CONNECTING AND OPERATING THE MINI DVI SWITCHER
How to Connect the Mini DVI Switcher to your devices
1 Connect the supplied DVI cables from the DVI sources into the DVI Switcher Input.
2 Connect the cable from your display (monitor or projector) into the DVI Out of the
Mini DVI Switcher.
How to Operate the Mini DVI Switcher
1 Use the front panel push button to switch between sources.
2 Alternatively, use the RMT2-IR remote control port to remotely toggle between sources.
Operation Notes
The output signal may need to be equalized depending on the length and quality of the
DVI cables that are being used. If, after connecting all equipment and powering on the
system, there is either no picture or video noise on the output display device, the signal
may have to be equalized. For equalization, there are two EQ knobs on the front panel.
Each EQ knob represents each input. According to the length of the cable, the EQ knob
should be adjusted.

RMT2-IR INSTALLATION
1. Remove battery cover from the back of the RMT2-IR remote.
2. Verify that DIP switches 1 and 2 are in the down (OFF) position.
3. Hold the battery so that you can see the positive side facing up. The side that is not
marked must be facing down.
5. Insert the battery into the open battery slot in the remote control.
6. Test the RMT2-IR remote by pressing ONLY one button at a time. The indicator light
on the remote will f 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 1-7 will have to be repeated.
Note: The RMT2-IR ships with two batteries. One battery is required for operation, the
second battery is complimentary.
The optional IR extender
RMT-EXTIR allows you to relocate
your Mini DVI Switcher and still have
IR control of the Mini DVI Switcher
Note: The 3.5 mm mini-stereo jack located on the front of the unit is used to connect the optional IR extender (shown above). It can also be used for connecting a
cabled contact closure remote control (such as Gefen's EXT-RMT-2).

IR CODE CONFIGURATION
Why would I need to change the remote channel?
In some instances, the Mini DVI Switcher may use IR codes that conf ict with other
IR remote control devices. The unit may switch inputs when another brand IR remote
control is used or the RMT-2IR may cause other brand IR controlled devices to behave
unexpectedly.
I am experiencing the issues listed above. What do I do?
In these cases it is recommended to change the IR channel that the RMT-2IR remote
control and the Mini DVI Switcher use. The IR channel is conf gured independently on the
RMT-2IR remote control and the Mini DVI Switcher but the channel selection must match
on both units for proper operation.
How Do I change the Remote Channel?
There are service DIP switches on the RMT-2IR remote control and also inside the Mini
DVI Switcher. Use the diagrams below to locate and change the IR channel to one that
is not the default. Remember that the channel must match on both the unit and remote

Remove the battery cover on the rear side of the RMT-2IR remote control to
expose the DIP switches.
