input #1 and the DVI port of DVI source #1 connects using a male to male DVI

cable. The DVI port of DVI source #2 connects to DVI input #2. The DVI port of

DVIsource#3connects toDVI input#3.The DVIport ofDVI source#4 connects

to DVI input #4. There are four (4) DVI outputs connecting to four (4) different

displays.

Note: The switching is done by using either the RMT-16-IR remote control or

through the RS232 port. The 4x4 DVI Matrix is rack mountable.

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.

USING THE 4X4 DVI MATRIX

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.
