CONNECTING AND OPERATING THE 4x1 DVI SWITCHER

How to Connect the 4x1 DVI Switcher to your devices

1 Connect the supplied DVI cables from the DVI sources into the DVI Switcher Input.

2Connect the cable from your display (monitor or projector) into the DVI Out of the

4x1 DVI Switcher.

How to Operate the 4x1 DVI Switcher

Use the RMT4-IR remote control port to remotely toggle between sources.

Operation Notes

The 4x1 DVI Switcher may also be powered from the input. The DVI source supplies 5v to

the switcher via pin-14 on the DVI cable.

The contact closure port is wired using a shielded CAT5 cable. Pins 1-4 to the shield

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

been selected.

RMT4-IR INSTALLATION

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

does not come included in the package.
