CONNECTING AND OPERATING THE 2x1 DVI DL SWITCHER
How to Connect the DL 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 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.
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 DL Switcher.
How to Operate the DL Switcher
1- Use the front panel push button to switch between sources.
2- Use the RMT2-IR remote control port to remotely toggle between sources.
3- Use the optional RMT-2 wired remote control to remotely toggle between sources.
Equalization control for the DVI DL Switcher
The external equalization knobs can be used to balance out signal noise
resulting from long cables for better picture quality. By turning the equalization knobs
counter-clockwise you will eliminate any noise and/or degradation in the signal. You
should be able to find a "sweet spot" somewhere in the middle.

Operation Notes
When turning on or rebooting your computers, the 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, 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.
*For the Dell 30" Display the internal and external equalization knobs will both need to
be adjusted to get a clean video signal. The internal EQ can be reached by removing 9
screws situated on the sides of the casing and the 6 hex nuts on the DVI connectors.
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 di-
rectly. Start your computer up and try switching. If your USB devices do come up nor-
mally 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 rapidly. 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 operation, the
second battery is complimentary.
Optional RMT-2 wired remote control
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 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 2 and 3 in-
side the 2X1 DVI DL Switcher respectively. Switch the switches inside 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.
