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.  
2 Connect the cable from your display (monitor or projector) into the DVI Out of the  
4x1 DVI Switcher.

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 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 RMT4-IR ships with two batteries. One battery is required for operation, the  
second battery is complimentary.
