DVIGear: DVI-7312 DVI Fiber Optic Extender, 2x LC / QSG / Web

DVI-7312
Single-Link DVI
Fiber Optic Extender, 2x LC
Quick Start Guide
Introduction
DVI-7312 is a Fiber Optic Extender designed to transmit single-link DVI signals over fiber optic cables at
distances up to 2000 meters (~1.2 miles). This extender provides exceptional signal fidelity and supports
a wide range of input resolutions. The unit consists of an optical transmitter module that converts the DVI
input signal into high-speed light pulses for transmission over two (2) detachable multi-mode or singlemode glass fibers and an optical receiver module that converts the light pulses back to a DVI signal for
display on a monitor or projector. A programmable memory chip in the transmitter unit captures and
stores the EDID from the connected display, thereby eliminating the need for copper cables. These
features make the DVI-7312 the ideal solution for any application that demands flawless image quality
from DVI signals that must be extended over very long cable distances.

Installation Instructions
This product consists of a DVI-7312-TX Transmitter Unit and a DVI-7312-RX Receiver Unit. These units
are interconnected by means of a two-channel LC optical cable utilizing either 50/125μ multi-mode fiber,
or 9/125μ single-mode fiber (see application drawing on page 1).
1.) Learn the EDID from the destination device (see instructions on page 4).
2.) Connect the Transmitter Unit to the DVI output port of the signal source (e.g. PC).
3.) Connect the Receiver Unit to the DVI port of a destination device (e.g. digital display).
4.) Each unit has two (2) Optical ports which are marked on the bottom of the unit with the
numbers 1 and 2. Connect each strand of the LC terminated fiber optic cable to the
corresponding number on both the Transmitter and Receiver Units.
5.) Connect the External AC Power Adapter to the power input jack on the Receiver Unit.
6.) Apply power to the display device, then apply power to the source device. A picture should appear
on the display within a few seconds.
Power Sources
The Receiver Unit must draw power from the supplied External AC Power Adapter. It does not draw
power from the monitor to which it is connected. However, the Transmitter Unit can draw power from
the source device for operation. In the event that the source cannot provide adequate power for the
transmitter, an optional External AC Power Supply is available (part number DVI-7210-PS).

Instructions for Learning the EDID from a Display
1.) Apply power to the display.
2.) Connect the DVI-7312 Transmitter unit to the display’s DVI input port.
3.) Connect the External AC Power Adapter to the Transmitter unit.
4.) Press the Learn EDID button (page 2 - #5) by manually inserting a stylus into the side of the
Transmitter unit. If the EDID is properly read, the BLUE Indicator LED (page 2 - #2a) should
illuminate once.
5.) Remove the External AC Power Adapter from the Transmitter unit.
6.) Disconnect the Transmitter unit from the display and connect it to the DVI signal source.
7.) Follow the Installation Instructions (3-6) listed on page 3.
