INTRODUCTION
Thank you for purchasing the 4x4 HDMI Matrix.
The 4x4 HDMI Matrix switches four HDTV sources to any four HDMI displays.
The 4x4 HDMI Matrix switcher has four HDMI inputs and four HDMI outputs. Matrix input
#1 and the HDMI port of HDTV source #1 connects using a male to male HDMI cable. The
HDMI port of HDTV source #2 connects to HDMI input #2. The HDMI port of HDTV source
#3 connects to HDMI input #3. The HDMI port of HDTV source #4 connects to HDMI input
#4. There are four (4) HDMI 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 HDMI Matrix is rack mountable. Any HDTV with DVI inputs can be
connected to the HDMI outputs of the matrix by using a DVI to HDMI adapter if the cable
used is DVI.

Controlling the 4x4 HDMI 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 HDMI Matrix - When your computer
boots up, it looks for an EDID (extended display identification data) from the dis-
play to tell it what monitor is connected and what resolution to output. During 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 ca-
pable of running at the same resolution then this step does not matter.

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 facing 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 pictured below.
4. Dip Switches 1 and 2 in the RMT16-IR correspond with Dip Switches 3 and 4 inside
the 4x4 HDMI Matrix respectively. Switch the switches inside the 4x4 HDMI Matrix to
match the same Remote Channel as the RMT16-IR. The 4x4 Matrix is now set to a new
IR Code.
