INTRODUCTION Congratulations on your purchase of the GefenPRO 8x8 DVI Dual Link Matrix. Your complete satisfaction is very important to us. GefenPRO In the realm of video distribution, certain features are invaluable in a commercial or broadcast environment. Accommodations such as a build-in power supply and flat black rack-mount enclosures set GefenPRO apart from our traditional products.
OPERATION NOTES READ THESE NOTES BEFORE INSTALLING OR OPERATING THE GEFENPRO 8X8 DVI DUAL LINK MATRIX • The 8x8 DVI Dual Link Matrix does not support HDCP content. • When the Matrix is used for the first time, make sure that a DVI monitor is powered and connected to one of the DVI outputs on the 8x8 DVI Dual Link Matrix before applying power. By default, the Local EDID is read from the connected monitor and is copied to all 8 DVI inputs once the Matrix has been turned on.
FEATURES Features • Increases productivity • Supports resolutions up to 1920x1200 (Single Link) and 3840x2400 (Dual Link) • Front panel control buttons for local switching • Serial RS-232 interface for remote control via a computer or control automation devices • IP Control • Discrete IR remote control switching • Advanced EDID management permits upload of custom internal or external EDID settings • Supports DDWG standards for DVI • Built-in power supply • Output masking command • Stand

PANEL DESCRIPTIONS Back Panel 1 110 / 220 V AC (50/60 Hz) Power Receptacle Connect the included AC power cord from this receptacle to an available electrical outlet. 2 Fuse Drawer Each power receptacle houses a fuse drawer. Within each fuse drawer are two (2) 250 V fuses. One fuse is active and the other is a spare. 3 DVI Input Ports 1-8 Connect DVI source devices to these ports.
CONNECTING THE 8X8 DVI DUAL LINK MATRIX How to Connect the 8x8 DVI Dual Link Matrix 1. Connect up to 8 DVI Dual Link source devices to the inputs on the rear panel of the 8x8 DVI Dual Link Matrix using the supplied DVI dual link cables. 2. Connect up to 8 DVI Dual Link monitors to the outputs on the rear panel of the 8x8 DVI Dual Link Matrix with user-supplied DVI dual link cables. 3.
FRONT PANEL DISPLAY Main Display The Main Display of the GefenPRO 8x8 DVI Dual Link Matrix is a 16 character 2 line display. This display will show the standby screen and will also be used to aid in performing routing commands. When the unit is powered on, the following screen is displayed: After a few moments, the Standby Screen is displayed.
FRONT PANEL DISPLAY Displaying the Routing Status From the main screen, press the Select button. When the arrow cursor is next to OUTPUT, pressing the ◄ or ► buttons on the front panel will show the current routing state of each input and output. The illustration below shows the routing state of output 1. Pressing the ► button again will display the routing state of output 2 and so on.
IR REMOTE CONTROL UNIT Layout and Description (RMT-848IR) 1 2 1 LED Button Press Indicator This LED will be activated momentarily each time a button is pressed. 2 Display and Source Selection Buttons These buttons are used to select which source is routed to a display See page 14 for information on using the IR Remote Control unit. NOTE: An Activity Indicator that flashes quickly while holding down any one of the 16 buttons indicates a low battery.
IR REMOTE CONTROL UNIT Installing the Battery 1. Remove the battery cover on the back of the IR Remote Control unit. 2. Insert the included battery into the open battery slot. The positive (+) side of the battery should be facing up. 3. Replace the battery cover. The Remote Control unit ships with two batteries. One battery is required for operation and the other battery is a spare. Battery Slot CAUTION: Risk of explosion if battery is replaced by an incorrect type.
IR REMOTE CONTROL UNIT Setting the IR Channel In the event that IR commands from other remote controls interfere with the supplied IR Remote Control unit, changing the IR Remote Control’s IR channel will fix the problem. The IR Remote Control unit has a bank of DIP switches used for setting the IR channel. The DIP switch bank is located underneath the battery cover.
IR REMOTE CONTROL UNIT IR Remote Control Key Mapping Each input and output on the 8x8 DVI Dual Link Matrix is represented by a button on the IR Remote Control unit. The table below lists the corresponding inputs and outputs. Remote Button Monitor / Source 1 1 2 2 3 3 4 4 5 5 6 6 7 7 8 8 Routing Sources using the IR Remote Control unit Issuing a routing command is a two step process. The first step is to select the monitor where the source will be routed.
EDID MANAGEMENT EDID. What is it and what is it used for? Under normal circumstances, a source device (digital and analog) will require information about a connected device/monitor to assess what resolutions and features are available. The source can then tailor its output to send only resolutions and features that are compatible with the attached device/monitor.
IP CONFIGURATION Configuring the IP Address The 8x8 DVI DL Matrixx supports IP-based control using Telnet or the built-in Web-based GUI. To set up IP control, the network settings for the 8x8 DVI DL Matrix must be configured via RS-232. The default network settings for the matrix are as follows: IP Address: Subnet: Gateway: HTTP Port: Telnet Port: 192.168.1.72 255.255.255.0 192.168.1.254 80 23 1. Connect an RS-232 cable from the PC to the 8x8 DVI DL Matrix. 2. Launch a terminal emulation program (e.g.
RS-232 SERIAL CONTROL 54321 12345 9876 6789 Only Pins 2 (RX), 3 (TX), and 5 (Ground) are used on the RS-232 serial interface RS232 Settings Bits per second ................................................................................................. 19200 Data bits .................................................................................................................... 8 Parity ..............................................................................................................
