2x1 DVI SL OPERATION NOTES

Operation Notes
When turning on or rebooting your computers, the DVI SL 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
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 1 and 2 on the
outside of the 2x1 DVI SL Switcher respectively. Flip the switches on the outside of the
2x1 DVI SL Switcher to match the same Remote Channel as the RMT 2-IR. The 2x1
DVI SL Switcher is now set to a new IR Code.
