INTRODUCTION

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.

OPERATION NOTES

READ THESE NOTES BEFORE INSTALLING OR

OPERATING THE 8X8 DVI MATRIX

8x8 DVI Matrix is not HDCP compliant•
By default, EDID routing is based on the fi rst connected display to a source. •
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 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.

CONNECTING AND OPERATING THE 8X8 DVI MATRIX

How to Connect the 8x8 DVI Matrix

Connect up to 8 DVI sources to the DVI Input ports on the 8x8 DVI Matrix 1.
using the supplied DVI cables.

Connect up to 8 DVI displays to the DVI Output ports on the 8x8 DVI Matrix 2.
using user supplied DVI cables.

Optionally connect up to 8 remote switching units (Part# EXT-RMT-MATRIX-3.

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
(500 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-16-IR 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-16-IR remote control.
Please see page## 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 RS­232 port located on the rear panel of the EXT-RMT-MATRIX-848.

Routing video to a particular display using the remote control is a 2 step process.
The fi rst input step is to select the display (Output column). The second input step is
to select the source (Input column) that will be routed to the display that was chosen
in the fi rst step. The example below shows how to route input source number 7 to
display C.

Press the remote button labeled 4 (display) on the RMT-16 IR remote control.1.
Press the remote button labeled 15 (source) on the RMT-16 IR remote control.2.

RMT-16-IR IR CHANNEL CONFIGURATION

The RMT-16-IR remote control has 4 discrete channels for use if the default IR
code set confl icts with other remote control commands in your setup. There are 2
DIP Switches underneath the battery on the RMT-16-IR 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 confi guration. Information on the remaining DIP Switch banks can be found
in Appendix A. See below for DIP Switch confi gurations for each of the available
remote channels.

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 by the serial communications port.

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##)
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”

Example: #FunctionName_param1_param2_param3_param4…\r

This function set the remote channel that must match the GEFEN RMT-16-IR
remote control.
