CONNECTING AND OPERATING THE 4x1 DVI SWITCHER
How to Connect the 4x1 DVI Switcher to your devices

cause the unit to switch to inputs 1-4. Pins 5-8 are feedback letting you know what has
been selected.

1. Remove battery cover from the back of the RMT4-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 RMT4-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 RMT4-IR ships with two batteries. One battery is required for operation, the
second battery is complimentary.
How to Operate the IR Extender Eye (optional)
Plug in the IR extender eye to the extender port on the back of the switcher. As soon as
the IR extender eye is plugged in you can extend your IR signal. The IR extender eye
