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 rst connected display to a source.  
For example, if monitor A is the 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  
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  
(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 RS-  
232 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 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 rst step. The example below shows how to route input source number 7 to  
display C.  
1. Press the remote button labeled 4 (display) on the RMT-16 IR remote control.  
2. Press the remote button labeled 15 (source) on the RMT-16 IR remote control.  
3. The video from DVI Input 7 should now appear on the display connected to  
monitor output C.  
Repeat these steps to route any video source to any display.

RMT-16-IR IR CHANNEL CONFIGURATION  
The RMT-16-IR remote control has 4 discrete channels for use if the default IR  
code set conicts 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 conguration. Information on the remaining DIP Switch banks can be found  
in Appendix A. See below for DIP Switch congurations for each of the available  
remote channels.

(PRODUCT SOLD SEPARATELY)  
Once the EXT-RMT-MATRIX-848 Remote is installed and connected to a remote  
output port on the 8x8 DVI Matrix, use the direct selection buttons to chose a  
source to view. Once a source is chosen, its corresponding LED should become  
active. Optionally, switching can be done using an RMT-8-IR remote control (sold  
separately) or through the RS-232 serial communications port on the rear panel.

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.

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