INTRODUCTION
Thank you for purchasing the 4x4 HDTV Matrix.
The 4x4 HDTV Matrix switches four HDTV sources to any four DVI displays.
The 4x4 HDTV Matrix switcher has four DVI inputs and four DVI outputs. Matrix input #1
and the DVI port of source #1 connects using a male to male DVI cable. The DVI port of
source #2 connects to DVI input #2. The DVI port of source #3 connects to DVI input #3.
The DVI port of 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 the RMT-16-IR remote control or through
the RS232 port. The 4x4 HDTV Matrix is rack mountable. Any HDTV with HDMI inputs can
be connected to the DVI outputs of the matrix by using a DVI to HDMI adapter or cable.

USING THE 4X4 HDTV MATRIX
1
Connect all the sources to the HDMI inputs on the 4x4 HDTV Matrix, using the
supplied cables.
2
Connect the HDMI/DVI displays to the outputs on the 4x4 HDTV Matrix.
3
Connect the 24VDC powersupply to the 4x4 HDTV Matrix

Controlling the 4x4 HDTV 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 HDTV Matrix - When your computer
boots up, it looks for an EDID (extended display identifi cation 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 capable 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 fl 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 RMT16-IR ships with two batteries. One battery is required for operation, the
second battery is complimentary.

DIP SWITCH GUIDELINES
DIP SWITCH
EDID GUIDE
Extended display identifi cation data (EDID) is a data structure provided by a display to
describe its capabilities to any source that asks for it. The EDID includes manufacturer
name, product type, timings supported by the display, display size, luminance data, (for
digital displays only) pixel mapping data, supported audio channels and formats. This
information is used by the source to cater its output to resolutions and audio formats
that are supported by the display.
Additional EDID modes are available and confi gured using a combination of dip
switches 1, 2, and 5. Please refer below for the different EDID modes.
To access the Dip Switches, remove all screws from the bottom and sides of the
Gefen unit. Remove the hex screw heads from each side of the RS-232 and DVI ports.
Carefully slide the unit apart. The 8 Bank of Dip Switches are located on the main PCB.
Once adjustments are complete, slide the unit back together and replace all removed
screws.
EDID Mode 0 (Switch 1=OFF Switch2=OFF Switch5=ON)
-EDID is copied from the fi rst HDMI port
EDID Mode 1 (Switch 1=ON Switch2=OFF Switch5=ON)
-Same as Mode 0 and adds basic audio support
EDID Mode 2 (Switch 1=OFF Switch2=ON Switch5=ON)
-Same as Mode 0 and adds full audio support
EDID Mode 3 (Switch 1=ON Switch2=ON Switch5=OFF)
-EDID is generated based on the common video and audio features of all of the
connected devices
EDID Mode 4 (Switch 1=OFF Switch2=ON Switch5=OFF)
-Same as Mode 3 and adds basic audio support
EDID Mode 5 (Switch 1=ON Switch2=OFF Switch5=OFF)
-Same as Mode 3 and adds full audio support
EDID Mode 6 (Switch 1=OFF Switch2=OFF Switch5=OFF) DEFAULT
-EDID is generated based on the common video features of all of the connected
devices and the combined audio features of all of the connected devices

IR CODES
In the event of IR confl icts, 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 HDTV Matrix respectively. Switch the switches inside the 4x4 HDTV Matrix to
match the same Remote Channel as the RMT16-IR. The 4x4 Matrix is now set to a new
IR Code.

Switches must be in the OFF position.

TERMINOLOGY
DDC
Short form for Display Data Channel. It is a VESA standard for communication between
a monitor and a video adapter. Using DDC, a monitor can inform the video card about its
properties, such as maximum resolution and color depth. The video card can then use
this information to ensure that the user is presented with valid options for confi guring the
display.
DDWG
Digital Display Working Group DDWG are the creators of the DVI specifi cation.
DVI
Digital Visual Interface. Connection standard developed by Intel for connecting computers
to digital monitors such as fl at panels and DLP projectors. A consumer electronics version,
not necessarily compatible with the PC version, is used as a connection standard for HDTV
tuners and displays. Transmits an uncompressed digital signal to the display. The latter
version uses HDCP copy protection to prevent unauthorized copying.
HDCP
High-Bandwidth Digital Content Protection. Created by Intel, HDCP is used with HDTV
signals over DVI and HDMI connections and on D-Theater D-VHS recordings to prevent
unauthorized duplication of copy written material.
HDMI
The High-Defi nition Multi-media Interface (HDMI) is an industry-supported, uncompressed,
all-digital audio/video interface. HDMI provides an interface between any compatible digital
audio/video source, such as a set-top box, DVD player, and A/V receiver and a compatible
digital audio and/or video monitor, such as a digital television (DTV).
HDTV
High-Defi nition T elevision. The high-resolution subset of our DTV system. The A TSC defi nes
HDTV as a 16:9 image with twice the horizontal and vertical resolution of our existing system,
accompanied by 5.1 channels of Dolby Digital audio. The CEA defi nes HDTV as an image
with 720 progressive or 1080 interlaced active (top to bottom) scan lines. 1280:720p and
1920:1080i are typically accepted as high-defi nition scan rates.
RS-232
Recommended Standard 232. This is the de facto standard for communication through PC
serial ports. It can refer to cables and ports that support the RS232 standard.
VESA
Video Electronic Standards Association, a consortium of manufacturers formed to establish
and maintain industry wide standards for video cards and monitors. VESA was instrumental
in the introduction of the Super VGA and Extended VGA video graphics standards with
a refresh rate of 70 Hz, minimizing fl icker and helping to reduce user eyestrain and
fatigue.
