Congratulations on your purchase of the 8x8 DVI Matrix. Your complete
satisfaction is very important to us.
Gefen
Gefen delivers innovative, progressive computer and electronics add-on solutions
that harness integration, extension, distribution and conversion technologies.
Gefen’s reliable, plug-and-play products supplement cross-platform computer
systems, professional audio/video environments and HDTV systems of all sizes
with hard-working solutions that are easy to implement and simple to operate.
The Gefen 8x8 DVI Matrix
Now you can easily combine eight cross-platform computers and eight digital
displays without networking. Our 8x8 DVI Matrix provides a simple, reliable and
highly effective method of creating multiple computer workstations, with each
workstation capable of accessing any one of the computers or sources at any
time by remote control. You also have the option of setting up the eight stations
locally or extending them with a Gefen extender.
How It Works
The 8x8 Matrix has eight DVI inputs and eight DVI outputs. You simply connect
your eight computer DVI ports to the 8x8 Matrix inputs, then connect your eight
DVI displays to the 8x8 Matrix outputs.

READ THESE NOTES BEFORE INSTALLING OR
OPERATING THE 8X8 DVI MATRIX
• The 8x8 DVI Matrix is HDCP compliant when used in EDID pass-through
mode (when a single DVI input is mapped to a single DVI output). Additional
Matrix outputs which attempt to route video signals to a source device that
has already made an HDCP connection with an HDCP-compliant display will
not be able to display an image.
• By default, EDID routing is based on the first connected source and display.
For example, if monitor A is the first display to connect to source 1 its EDID
will be used. All other displays that connect to source 1 thereafter will
have its EDID ignored. If display 1 switches to another source a hot-plug
signal will be sent and the EDID from the next display that is connected, in
numerical order, will be used.
• The Status Output display will only list the current display/source routing.
• There is no internal scaling in the 8x8 DVI Matrix. All of the attached
monitors must be able to display the resolutions output by the source
devices. For maximum compatibility it is recommended that only one
compatible/common resolution be used by all of the source devices.

How to Connect the 8x8 DVI Matrix
1. Connect up to 8 DVI sources to the DVI Input ports on the 8x8 DVI Matrix
using the supplied DVI cables.
2. Connect up to 8 DVI displays to the DVI Output ports on the 8x8 DVI Matrix
using user supplied DVI cables.
3. Optionally connect up to 8 remote switching units (Part# EXT-RMT-MATRIX-
848) to the RJ-45 Input ports on the rear panel on the 8x8 DVI Matrix using
user supplied CAT-5, CAT-5e or CAT-6.
NOTE: Maximum extension of the EXT-RMT-MATRIX-848 units are 330 Feet
(100 Meters).
Operating the 8x8 DVI Matrix
There are 2 main ways to control the 8x8 DVI Matrix. Local and remote control.
Local control is done using the included RMT-848IR remote control. Remote
control is done using the optional EXT-RMT-MATRIX-848 switching units.
Local Control
To control the unit locally, please use the included RMT-848IR remote control.
Please see page 12 for usage information.
Remote control
To control the unit remotely, please use the EXT-RMT-MATRIX-848 remote
switcher. Each remote switcher has 8 direct select push-buttons that correspond
to DVI inputs 1 through 8. Press the push-button corresponding to the desired
source for viewing. There is also the option to use RS-232 switching via the RS-
232 port located on the rear panel of the EXT-RMT-MATRIX-848.
CONNECTING AND OPERATING THE 8X8 DVI MATRIX

8X8 DVI MATRIX REMOTE DESCRIPTION & OPERATION
Input Sources and Displays connect to the Matrix on the rear panel. Sources use
input connectors 1 thru 8 while Displays use connectorsA thru H. Please see page 6
for the Matrix Back Panel Layout diagram for details.
Routing a Source to a Display is done with the RMT-848IR Remote Control unit,
shown immediately below.
Number Keys (Sources)
Letter Keys (Displays)
How to Route Sources to Displays
Routing is done in two simple steps. There is one button-press for each step. For
example, here is how to route Source 4 to Display C:
1. Press the “C” letter key on the Remote once to select Output/Display “C”.
2. Press the “4” number key once to select Input Source 4.
Source 4 will now be routed to Display C and a crisp, vibrant picture of the Source 4
will now appear on Display C. The LCD Display will show the route created (circled
below):
Repeat these steps to route any video source to any display.

RMT-848IR REMOTE CONTROL 8x8 DVI Matrix
The RMT-848IR remote control has 4 discrete channels for use if the default IR
code set conflicts with other remote control commands in your setup. There are 2
DIP Switches underneath the battery on the RMT-848IR remote control. These DIP
Switches must match the IR channel in use on the 8x8 DVI Matrix. The underside
of the 8x8 DVI has multiple banks of DIP Switches. Please see the diagram of the
8x8 DVI Matrix below for the correct bank and DIP Switches that are used for IR
channel configuration. Information on the remaining DIP Switch banks can be found
inAppendix A. See below for DIP Switch configurations for each of the available
remote channels.

Gefen has specifically engineered their products to work with the TIA/EIA-568-B
specification. Please adhere to the table below when field terminating cable for
use with Gefen products. Failure to do so may produce unexpected results and
reduced performance.
CAT-5, CAT-5e, and CAT-6 cabling comes in stranded and solid core types.
Gefen recommends using solid core cabling. CAT-6 cable is also recommended
for best results.
Each cable run must be one continuous run from one end to the other. No splices
or use of punch down blocks.
