About this Manual

This manual describes the Extron® DVI 201 family of Digital Visual Interface (DVI™) Extenders,
which consists of DVI 201 Tx transmitters and DVI 201 Rx receivers. This manual describes
how to install, operate, and configure them.

About the DVI 201 Transmitter and Receiver

The Extron DVI 201 Tx/Rx is a family of DVI transmitters and receivers (figure 1), in
enclosures that support different mounting options. A transmitter and receiver pair extends
the usable distance of DVI or HDMI digital video and RS-232 control signals over two
Category (CAT) 5/5e/6 unshielded twisted pair (UTP) or shielded twisted pair (STP) cables.
Extron DTP26 digital cable is also recommended. The DVI 201 A D transmitter and receiver
also route audio, but not on the TP link. The video and control (and audio, if applicable)
signals can be transmitted up to 200 feet (60 m).

Figure 1. Typical Transmitter and Receiver Application

A DVI 201 system consists of a transmitter (Tx) and a receiver (Rx). The pair can handle
a single link of DVI-D digital video and a bidirectional RS-232 link. The DVI 201 A D also
converts a computer audio input into balanced or unbalanced stereo audio output.

DVI 201 • Introduction 1

There are two subsets of transmitters and receivers in two different enclosures or form
factors:

• DVI 201 Tx/Rx — These units are housed in quarter rack width metal enclosures.

They can be set on a tabletop or mounted in a rack, under or through furniture, or to
a projector pole. The transmitter in this form factor has a local monitor output.

NOTE: The non-Decora models do not input, transmit, receive, or output audio.

• DVI 201 A D Tx/Rx — These units are housed in enclosures that can be mounted

in UL standard wall boxes with Decora®-style face plates. These units also convert
computer level audio to balanced or unbalanced stereo audio.

NOTES: • A non-Decora transmitter or receiver is partially compatible with a

Decora receiver or transmitter.

• A mixed form factor system can transmit and receive video and RS-232
communications.

• A mixed form factor system cannot transmit and receive audio, as the
non-Decora models do not input, transmit, receive, or output audio.

The units can be purchased as a pair (of the same form factor) or individually. Each
purchased pair and each individual transmitter is shipped with a single external desktop
12 VDC power supply that accepts 100 to 240 VAC, 50-60 Hz input. A single power
supply connected to either the transmitter or the receiver can power both units through
one of the TP cables that link the units.

NOTE: In this manual, the terms “DVI 201,” “DVI 201 Tx,” “DVI 201 Rx,”

“transmitter,” and “receiver” refer to the applicable unit in either form factor,
unless otherwise specified.

DVI 201 • Introduction 2

TP Cable Advantages

Twisted pair cable is much smaller, lighter, more flexible, and less expensive than coaxial
or DVI cable. These transmitter and receiver twisted pair (TP) products make cable runs
simpler and less cumbersome. Termination of the cable with RJ-45 connectors is simple,
quick, and economical.

NOTES: • The transmitter and receiver pair works with unshielded twisted pair

• Do not use Extron UTP23SF-4 Enhanced Skew-Free™ A/V UTP cable to

Control Communications

The RS-232 or infrared (IR) communications are pass-through only; the transmitter and
receiver do not generate or respond to these signals.

Transmission Distance

The maximum transmission distance is determined by the resolution of the signal and the
TP cable that is used.

• With CAT 5/5e/6 UTP cable, the Tx/Rx pair can transmit and receive 720p and

1080i HDTV or XGA video signals up to 200 feet (60 m) and 1080p HDTV or UXGA
video up to 100 feet (30 m).

• With CAT 5/5e/6 STP cable, the Tx/Rx pair can transmit and receive 720p and

1080i HDTV or XGA video signals up to 200 feet (60 m) and 1080p HDTV or UXGA
video up to 125 feet (38 m).

(UTP) or shielded twisted pair (STP) cables; but, to ensure FCC Class A
and CE compliance, STP cables are required.

link the transmitter and receiver. Skew-free A/V cable was designed for
most Extron TP transmitter/receiver applications, but the DVI 201 Tx/Rx
does not work properly with this cable.

NOTES: • The transmission distance varies greatly, depending on the signal

• For resolutions of 1600x1200, 1920x1200, and 1080p, Extron strongly

resolution, type of cable used, graphics card, and display used in the
system.

recommends DTP26 cable, or equivalent. Extron DTP26 cable consists
of four individually shielded copper pairs and an overall braided shield
that help reduce crosstalk. DTP26 cable extends these resolutions up to
150 feet (45 m).

DVI 201 • Introduction 3

Features

Transmits single link DVI-D signals over two CAT 5/5e/6 cables — Standard twisted
pair cables provide an economical, easily installed cable solution.

Local monitor output (DVI 201 Tx [non-Decora] only) —

The DVI 201 Tx transmitter features a DVI-D output for connection to a local monitor.

Supports DDC and HDCP copy protection transmission — The Tx/Rx pair fully
supports long distance transmission of the DDC and HDCP signals.

Control communications pass-through — Bidirectional RS-232 or IR control signals
can be transmitted alongside the DVI signal, so that the remote display can be controlled
without the need for additional cabling.

Audio routing — The DVI 201 A D Tx/Rx also routes unbalanced stereo audio when both
units are the Decora form factor.

Supports CEC signal transmission

1-inch high, quarter rack width, metal enclosures (DVI 201 Tx and DVI 201 Rx
[non-Decora] only)— With low profile enclosures, both transmitter models and both

receiver models can be discreetly installed in locations such as behind a plasma or LCD
flat-panel display.

Wall-mountable enclosures (DVI 201 A D Tx and DVI 201 A D Rx [Decora] only)

External 100 VAC to 240 VAC, 50-60 Hz, international power supply
(part #70-055-01) — Included with units sold as a paired system and with transmitters

Remote powering of transmitter or receiver — Only one power supply is necessary to

power both devices.

UL guidelines for rack mounting

(2) 4-40 x 3/16"
Screws

Use 2 mounting holes on
opposite corners.

Rack Shelf

1/4 Rack Width Front
False Faceplate

The following Underwriters Laboratories (UL) guidelines pertain to the installation of a
DVI 201 unit onto a rack.

1. Elevated operating ambient — If installed in a closed or multi-unit rack assembly,

the operating ambient temperature of the rack environment may be greater than
room ambient. Therefore, consider installing the equipment in an environment
compatible with the maximum ambient temperature specified by the manufacturer
[Tma = +32 to +122 °F (0 to +50 °C)].

2. Reduced air flow — Installation of the equipment in a rack should be such that the

amount of air flow required for safe operation of the equipment is not compromised.

3. Mechanical loading — Mounting of the equipment in the rack should be such that a

hazardous condition is not achieved due to uneven mechanical loading.

4. Circuit overloading — Consideration should be given to the connection of the

equipment to the supply circuit and the effect that overloading of the circuits might
have on overcurrent protection and supply wiring. Appropriate consideration of
equipment nameplate ratings should be used when addressing this concern.

5. Reliable earthing (grounding) — Reliable earthing of rack-mounted equipment

should be maintained. Particular attention should be given to supply connections
other than direct connections to the branch circuit (such as the use of power strips).

Rack shelf mounting instructions

On the 6-inch and 9.5-inch rack shelves, the transmitter or receiver unit can be mounted
in the front or the rear of the rack.

1. Remove the feet from the bottom of the transmitter or receiver unit if installed.

2. Mount the transmitter or receiver unit on the rack shelf, using two 4-40 x 3/16-inch

screws in opposite (diagonal) corners to secure it to the shelf (figure 2).
