DVI DL 101
The Extron® DVI DL 101 is a dual link cable equalizer that extends DVI signals beyond the specified cable limits of
15 feet (5 m). It attaches to the end of a long cable run of up to 275 feet (84 m) for dual link and up to 200 feet (61 m)
for single link. The DVI DL supports all dual link DVI signals up to 330 MHz, including 2560x1600 or1080p at 60 Hz. It is
backwards compatible with single link, therefore supporting all single link rates up to 165 MHz, including 1920x1200 and
1080p at 60 Hz.
This guide provides basic instructions for an experienced installer to set up and operate this cable equalizer.

Installation Procedure
1. Turn off and disconnect all equipment from the
power source.
2. (Optional) If desired, mount the DVI DL on a 9.5, 6,
or 3.5 inch deep rack shelf; a projector mounting
pole; or furniture.
3. Connect a DVI source device to the DVI-Dual Link
Input DVI-I connector on the front panel.
4. Connect a DVI output device to the DVI-Dual Link
Output DVI-I connector on the rear panel.
NOTE: Dual link DVI cables must be used for
dual link DVI signals. If a single link
DVI cable is used, only single link DVI
signals are possible.
5. Wire the provided power supply as illustrated below
and connect it to the 2-pole, 3.5 mm captive screw
connector on the rear panel.

CAUTION: Applying power with incorrect voltage polarity can damage the power supply and equalizer. Identify
the negative lead by the ridges on the side of the cord. (See the illustration above.)
CAUTION: Always use a power supply by Extron for the DVI DL 101. Use of an unauthorized power supply voids all
regulatory compliance certification and may cause damage to the supply and the DVI DL.
CAUTION: The power supply must not be permanently fixed
to the building structure or similar structures.
The power supply must not be located within
environmental air handling spaces or the wall
cavity.
The installation must be in accordance with the
applicable provisions of the National Electrical
Code ANSI/NFPA 70, Article 725 and the Canadian
Electrical Code, Part 1, Section 16.
The power supply must be located within the
same vicinity as the Extron A/V processing
equipment in an ordinary location, Pollution
Degree 2, secured to a podium, a desk, or an
equipment rack within a dedicated closet.

Input cable lengths
For the highest transmission rate of 330 MHz (for dual link) or 165 MHz (for single link), the maximum cable length should
be 200 feet (61 m). Longer cables can be used at lower rates.
The DVI DL can operate in dual link mode or single link mode. The table below shows the maximum cable lengths
recommended for each resolution in both modes.

Enabling the DDC Buffer
The DDC clock and data lines by default are routed straight through to the
output, bypassing the DDC buffer. However, if you experience any image
problems, changing this setting to engage the DDC buffer should correct
them.
To enable the buffer:
1. Remove the seven screws that hold the top cover onto the unit and the
two jack screws on either side of the front panel DVI input connector.
2. Slide the top cover forward until it clears the input connector, then lift it
off the unit.
3. With the DVI DL rear panel toward you, locate the two DDC jumpers
(J5 and J4) on the two sets of three pins in the lower-right corner of the
internal board. By default these jumpers are on the middle and outside
pins, which lets the DDC lines pass straight through without buffering.
4. Lift each jumper off its pins and slide it down onto the inside and middle
pins. (See figure 2 at right.)
5. Replace the top cover onto the unit and slide the cover back until the DVI
input connector protrudes through its slot in the front panel.
6. Replace the two jack screws and the seven Philips
screws that you removed in step 1.

NOTE: Avoid using couplers and adapters
between cables because this can
result in signal degradation.
