CONNECTING AND OPERATING THE 2x1 DVI SL SWITCHER

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

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.

You should now be able to switch using the IR Extender.
