Connecting Your DVI Extender
The Local Unit
The Local Unit connects to the video source (usually a computer) using a conventional
DVI cable. This unit draws power for itself and the Remote Unit using the DVI video

connection.
The Remote Unit
The Remote Unit connects to the video display using a conventional DVI cable, and
sends the image sent over the integrated cable from the video source to the display.
The Integrated Cable
The Local Unit and Remote Unit are interconnected by a special integrated cable that
performs two separate functions:
• Digital video signals are transmitted from the Local Unit to the Remote Unit over four
strands of fiber cable. The Digital Visual Interface (DVI) is composed of four separate
video channels: Red, Green, Blue and Clock. Each channel is transmitted over a separate
strand.
• In many applications, the source of video information (computer) needs to know the
capabilities of the display device to which it is connected. The most significant of these
parameters are the maximum resolution and maximum refresh rate of the screen.
Exceeding these values can result in a blank screen or even physical damage. This
information is stored in the display in a format known as EDID and is provided to the
computer using a protocol called DDC. This EDID/DDC information is obtained from
the display by the Remote Unit and transmitted to the Local Unit over a copper cable
that runs alongside the fiber strands. The information is then relayed to the computer
over the DVI cable.
Preparing Your Site
Before you can install the DVI Extender, you need to prepare your site.
1: Determine where the computer is to be located and set up the computer.
2: Determine where you want to locate the display
3: Confirm the integrated cable will reach both the computer and the display with
sufficient slack to avoid damaging the cable.

Installing the Local Unit
1: Place the Local Unit near the computer or other video source.
2: Connect the Local Unit to the DVI output of the video source. Do not use any
intermediate cable or adapter between the Local Unit and the computer.
Installing the Remote Unit
1: Place the Remote Unit near the DVI display.
2: Connect the Remote Unit to the DVI input of the display. Do not use any intermediate
cable or adapter between the Remote Unit and the display.
Completing the Installation
1: Switch on the computer and DVI display.
Troubleshooting
Symptom: The display screen is black.
Cause: The display is not receiving a signal from the Remote Unit.
Remedy: (1) Check that the display is powered.
(2) Check that the display is connected to the Remote Unit with a DVI cable.
Symptom: Display does not operate after computer wakes up from Standby mode.
Remedy: Power the display OFF then ON again.
Symptom: Display is distorted or noisy.
Cause: The screen resolution or refresh rate is too high for the display.
Remedy: (1) On the host computer, open the display properties dialog and select the
Settings tab. Ensure that the resolution is set to UXGA (1600 x 1200) at 60 Hz
refresh rate, or lower.
(2) Reset the system.
