4 Controlling the 4x4 DVI Matrix using the RMT16-IR:
Pressing Buttons... Switches...
1-4 Display 1 to view Source 1, 2, 3, or 4
5-8 Display 2 to view Source 1, 2, 3, or 4
9-12 Display 3 to view Source 1, 2, 3, or 4
13-16 Display 4 to view Source 1, 2, 3, or 4
*Note for computers connected to the DVI Matrix - When your computer
boots up, it looks for an EDID (extended display identification data) from the
display to tell it what monitor is connected and what resolution to output. Dur-
ing boot up of the computer you should have ONLY one output selected to
one input at a time so that the computer gets the EDID of the display that is
selected. If you have multiple outputs selected to one computer, the computer
will read the EDID of the last output selected to it. If all your displays are the
same, or all displays are capable of running at the same resolution then this
step does not matter.
You can also use a DVI Detective to eliminate the need to have that matrix
selected to the computer during bootup.

RMT16-IR Installation
1. Remove battery cover from the back of the RMT16-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 fac-
ing up. The side that is not marked must be facing down.
4. Test the RMT16-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 RMT16-IR ships with two batteries. One battery is required for
operation, the second battery is complimentary.

IR CODES
In the event of IR conflicts, please do the following:
1. Remove the battery cover from the back of the RMT16-IR remote.
2. Locate the Dip Switches above the batteries
3. Switch the Dip Switches on the RMT16-IR to any of the combinations pic-
tured below.
4. Dip Switches 1 and 2 in the RMT16-IR correspond with Dip Switches 1 and
2 inside the 4x4 DVI Matrix respectively. Switch the switches inside the 4x4
DVI Matrix to match the same Remote Channel as the RMT16-IR. The 4x4
DVI Matrix is now set to a new IR Code.
