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.

2x1 DVI DL OPERATION NOTES

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.

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 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 RMT2-IR ships with two batteries. One battery is required for operation, the second battery is complimentary.

IR CODE CONFLICTS

In the event of IR confl icts, 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.

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.
