1. INTRODUCTION
The DVI-7320 Dual-Link DVI Fiber Optic Extender enables the transmission of both single-link and dual-link DVI signals at distances up to 500 meters (100 meters with real DDC support) without any signal degradation. This makes it an ideal solution for applications where a dual-link DVI display must be extended from the signal source without introducing artifacts in the image.
Our professional digital distribution products have been serving the industry for over ten (10) years. DVIGear offers a full line of high-quality Digital Matrix Routers, Switchers, Splitters, Video Scalers, Up/Down/Cross Converters, Format Converters, Analog-Digital Converters, as well as a wide range of long reach Digital Cables, Extenders, and Optical Transmission systems.
This product offers several unique features and benefits:
• Supports both single-link and dual-link DVI signals.
• Long distance transport of high speed DVI signals using commercial-off­the-shelf 50µ / 125µ multi-mode fiber optic cable.
• Supports high resolution W-QXGA (2560x1600 pixels) monitors, such as the 30” Apple Cinema Display and 30” Dell 3008WFP.
• Supports cable lengths up to 500 meters in DDC Emulation Mode and up to 100 meters with Real DDC Mode.
• Supports two DDC operational modes:
Real Mode - uses one CAT5 cable to support direct DDC
communications (EDID / HDCP) with the connected display.
Emulation Mode - enables a memory device that can store the
connected display’s EDID information.

5. INSTALLATION AND OPERATION
This product consists of the DVI-7320-Tx Transmitter Unit and the DVI-7320-Rx Receiver Unit. The DVI-7320-Tx must be connected to the DVI output port of the signal source (such as a PC). The DVI-7320-Rx should be connected to the DVI input port of a digital display.

DVI-7320-Rx

The DVI signal components are routed from the DVI-7320-Tx to the DVI-7320-Rx via two distinct signal paths: the low-speed signals are sent over a copper CAT5 cable link, and the high-speed TMDS and clock signals are sent over seven (7) multi-mode fiber optic cables with LC connectors (see the picture below).
Each unit has seven (7) Optical ports that are marked with the numbers T1, T2, T3, T4, T5, T6, and T7 on the DVI-7320-Tx unit, and R1, R2, R3, R4, R5, R6, and R7 on the DVI-7320-Rx unit. It is important to connect each LC fiber optic cable to the corresponding number on both the DVI-7320-Tx and DVI-7320-Rx units.

Info: If present, the 8th fiber optic cable does not need to be connected as all
signals are transmitted over cables 1-7. The 8th fiber optic port (to the left of port T7 or R7) is unmarked and is a dummy port.

DDC Communications
When the DVI-7320-Tx unit is set for Real DDC operation, a CAT5 copper cable of suitable length must connected between the DDC ports of the DVI-7320-Tx and DVI-7320-Rx units. In the Real DDC Mode, the EDID of the connected display is presented to the DVI source device via DDC link to the DVI-7320-Tx unit. Since DDC communications are based on I2C technology, the maximum cable length for the DDC link (CAT5 cable) is 100 meters (328 ft.) as this is the limit of I2C extenders.
In the DDC Emulation Mode, the connected display’s EDID can be stored in an EDID memory device located in the DVI-7320-Tx unit. When the DVI source boots, up it reads the EDID information stored in the DVI-7320-Tx in the same way as if the display were connected directly to it. The DDC Emulation Mode eliminates the need for the copper DDC link; hence it allows much longer cable runs (up to 500 meters) to be used.
Programming the EDID Memory
1.) To program the EDID memory, remove all connections to the DVI-7320-Tx unit.
2.) Set the DDC switch on the DVI-7320-Tx to the Emulation position.
3.) Connect a DVI cable between the DVI-7320-Tx and the display.
4.) Connect the External AC Power Adapter to the DVI-7320-Tx.
5.) After a brief delay the red PWR LED will flash rapidly for 1-2 seconds, then turn OFF for a moment and finally turn back ON.
The EDID has now been successfully stored in the DVI-7320-Tx.

Power Connections
The DVI-7320-Tx unit can be powered by the DVI soruce only if the soruce device can provide sufficient drive current on Pin 14 of the DVI output connector. If this is not the case, an additional External Power Adapter (p.n. DVI-7320-PS) may be required to power the DVI-7320-Tx unit.
The DVI-7320-Rx unit cannot draw power from the connected display, but it can receive power from the DVI-7320-Tx unit, provided a copper CAT5 cable is used to link the DDC ports. If a CAT5 cable is not used, then connect the supplied External AC Power Adapter to the power input jack on the DVI-7320-Rx unit.
Info: If a CAT5 cable is used to link the DDC ports of both units, then only one
(1) External AC Power Adapter is needed, which can be connected to the DVI-7320-Tx unit.
6. TROUBLESHOOTING
If the system fails to display a signal, power OFF all devices and check that the following connections are properly installed:
• The DVI cables connected to the DVI-7320-Tx unit and the DVI-7320-Rx unit must be a dual-link DVI cables.
• All seven (7) strands of the fiber optic cable must be routed to LC connector port with the corresponding number on both the DVI-7320-Tx unit and the DVI-7320-Rx unit. For example, Strand #1 is connected to port T1 and R1; Strand #2 is connected to port T2 and R2, and so on.
• If using the Real DDC Mode, a suitable length CAT5 cable should be connected to the DDC ports on the DVI-7320-Tx and DVI-7320-Rx units.
• The External AC Power Adapter should be connected to the DVI-7320­Rx unit. If no CAT5 cable is used, then an additional External AC Power Adapter must be connected to the DVI-7320-Tx unit.
Once all connections have been verified, power ON the monitor first, then the Dual-Link DVI Fiber Optic Extender, and then finally the DVI signal source.
If the system still fails to display an image, check to ensure that the DVI signal source is compatible with the display by making a direct connection between the two so as to bypass the Dual-Link DVI Fiber Optic Extender. If there is still no image, then there is a compatibility issue between the source and the display that must be resolved.
After trying the above suggestions should the problem still persist, contact your dealer for additional suggestions.
