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

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.
