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.
INTRODUCTION

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 fi rst connected source and display.
For example, if monitor A is the fi rst 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.

1 LED Status Display
This display will list the current display/source routes.
Selected Source (1~8)
Monitor (A~H)
Monitor Output’s are labeled 1 through 8 on the rear panel of the 8x8 DVI
Matrix. These numbers correspond to the letters A through H on the LED Status
Display. The top row of letters will remain static while each input number below
will represent which source each of the displays are currently viewing.
HPD (Hot Plug Detect)
Whenever a display is connected/disconnected an HPD event will occur. This
will be displayed on the LED Status Display. A 2 stage status update will occur
whenever a HPD event occurs
1.
The fi rst stage will return the HPD status for all
outputs. H means that the HPD status is HIGH and an L indicates that the
HPD status is LOW. In the example above, all outputs except for A has an
HPD that is LOW, while output A has an HPD that is HIGH.
2.
The second stage will return the active monitor
status for all outputs. M means that a monitor has been detected and an S
indicates that no monitor is attached or is active. In the example above, all
outputs except for A are not detecting a monitor, while output A detects a
monitor on its output.
3 IR Receiver
Use the included RMT-848IR remote control to route video to the different
displays.
4 Power LED Indicator
This input indicator will become active once the included 24V DC power adapter
has been properly connected.

EDID MANAGEMENT QUICK START GUIDE
To use EDID Management functions, the EDID mode must be changed from
Pass-Through to LOCAL. Please follow the steps below to set this mode.
NOTE: LOCAL EDID mode does not support HDCP.
1. Locate Bank C on the underside of the 8x8 DVI Matrix.
2. Each input has a DIP switch associated with it. Select the inputs that will be
changed to LOCAL mode and fl ip their DIP switch to the ON position. By
default, all DIP switches are in the Pass-Through mode (OFF).
Once the selected inputs are in LOCAL mode an EDID can then be set for each
input. Follow the commands below to quickly load an EDID into the LOCAL bank
of each input. These instructions use the Windows application Hyperterminal. For
details on these and other RS-232 commands please see appendix B.
1. Connect a computer to the 8x8 DVI Matrix’s RS-232 port.
2. Use the RS-232 settings on page 15 to open a connection with the 8x8 DVI
Matrix from the computer using the Hyperterminal application.
3. To store an EDID of a connected display into a LOCAL storage location, type
in the following command:
#EDIDDSTOLO A 1
This example will store the EDID from the monitor connected to output
A to input 1. Simply modify the monitor and input characters to route any
monitor’s EDID to any input’s LOCAL storage.
This command supports multiple LOCAL storage parameters. For example,
to store the EDID from the monitor connected to the output A to the LOCAL
storage locations for all inputs (1 through 8), type the following command:
#EDIDDSTOLO A 1 2 3 4 5 6 7 8
4. To check the EDID of a connected monitor, type the following command:
#PRDSEDID A 1
This example will check the EDID from the monitor connected to output A.
Simply modify the monitor character (A-H) to check a different output
monitor’s EDID.
5. To check the EDID stored in any input’s LOCAL storage, type the following
command:
#PRLOEDID 1 1
This example will check the EDID that is stored in the LOCAL storage bank
for input 1. Simply modify the input character (1-8) to check a different
input’s stored LOCAL EDID.
20
APPENDIX B
The 8X8 DVI Matrix uses RS-232 serial communication for access to a number
of features. Please us this section for EDID storing, calling, and routing functions.
REMOTE FUNCTION
The remote functions are used to modify the setting of the product, such as: Input
to output routing, EDID memory management etc. These functions are available
only via serial communications on the RS-232 port.
HELP FUNCTION
To reference the commands listed in the following pages, simply type HELP and
then enter key to display a list of the available commands.
EDID STORAGE LOCATIONS
There are 2 storage locations for EDIDs.
The main storage location is located right in front of each input. These eight
locations will transmit an EDID directly to the source devices connected to each
input. These eight locations will be referred to as LOCAL in the following section.
The second storage location is an EDID storage bank that can support up to
seven EDIDs. Any EDID in this bank can then be uploaded to some or all of
the LOCAL EDID storage locations for use by the source devices. This storage
location will be referred to as the EDID BANK in the following section.
Modify By Shortcut
Switching Command
First character indicates the output monitor. Second character indicates the input
number.
Example: ‘A5’ routes input 5 to output monitor A
Matrix Status Command
The ‘M’ or ‘m’ command will return the current routing state.
Shortcut Routing Command
This command sets the matrix routing state according to a preset routing state.
First character is ‘S’ or ‘s’, second character indicates the state that is set by
function #PSASRS or #MSASRS (please see page 24)
Setting Function Menu
The ‘P’ or ‘p’ command will return the settings function menu.
Modify By Function
The syntax for each function is always the same. The ‘#” character is the start
fl ag followed by the function name in capital letter and a space. The space tells
the MCU that the function name is ending. Finally, the parameters required for
each function are separated by a space and ending by the ‘\r’ character or “Enter”
