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-onsolutions that harness integration, extension, distribution and conversion technologies. Gefen’s reliable,plug-and-playproducts supplementcross-platformcomputer systems, professional audio/video environments and HDTV systems of all sizes withhard-workingsolutions that are easy to implement and simple to operate.

The Gefen 8x8 DVI Matrix

Now you can easily combine eight cross-platformcomputers 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 first connected display to a source.

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-plugwill 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 theRJ-45Input ports on the rear panel on the 8x8 DVI Matrix using user suppliedCAT-5,CAT-5eorCAT-6.

NOTE: Maximum extension of the EXT-RMT-MATRIX-848units 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-IRremote control. Remote control is done using the optionalEXT-RMT-MATRIX-848switching units.

Local Control

To control the unit locally, please use the included RMT-16-IRremote control. Please see page## for usage information.

Remote control

To control the unit remotely, please use the EXT-RMT-MATRIX-848remote switcher. Each remote switcher has 8 direct selectpush-buttonsthat correspond to DVI inputs 1 through 8. Press thepush-buttoncorresponding to the desired source for viewing. There is also the option to useRS-232switching via the RS232 port located on the rear panel of theEXT-RMT-MATRIX-848.

Routing video to a particular display using the remote control is a 2 step process. The first 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 first 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-16IR remote control.

2.Press the remote button labeled 15 (source) on the RMT-16IR 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-IRIR CHANNEL CONFIGURATION

The RMT-16-IRremote 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 theRMT-16-IRremote 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 in Appendix A. See below for DIP Switch configurations for each of the available remote channels.

APPENDIX B

The 8X8 DVI Matrix uses RS-232serial 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 flag 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
