About this Guide

This guide describes the Extron DTP DVI 230 D family of Digital Visual Interface (DVI)
Extenders, which consists of the DTP DVI 230 D Tx and DTP DVI 230 D Rx. This guide
describes how to install, operate, and configure them.

About the DTP DVI 230 D Extenders

The Extron DTP DVI 230 D extenders are a family of DVI transmitters and receivers (see
figure 1) which are housed in enclosures that can be mounted in Underwriters Laboratories
(UL) standard wall boxes with Decora®-style face plates. A transmitter and receiver pair
extends the usable distance of DVI digital video and RS-232 or IR control signals over one
Category (CAT) 5e, 6, 6a, or 7 unshielded twisted pair (UTP) or shielded twisted pair (STP)
cable. The DTP DVI 230 D transmitter and receiver also route audio. The video, control, and
audio (if applicable) signals can be transmitted up to 230 feet (70 m).

Figure 1. Typical Transmitter and Receiver Application

A DTP DVI 230 D 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 or IR link.

The DTP DVI 230 D transmitter and receiver are sold separately. Each 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 the twisted pair cable that links the units.

DTP DVI 230 D Transmitter and Receiver • Introduction 1

Features

Twisted Pair 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.

NOTE: Do not use Extron UTP23SF-4 Enhanced Skew-Free AV UTP cable or STP201

cable to link the transmitter and receiver. The DTP HDMI 230 Tx/Rx does not work
properly with these cables.

Transmission Distance

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

Transmits single link DVI-D signals over one CAT 5e, 6, 6a, or 7 cable — Standard
twisted pair cables provide an economical, easily installed cable solution.

With CAT 5e, 6, 6a, or 7 UTP or STP cable — The transmitter and receiver pair can
transmit and receive 720p, 1080i or 1080p HDTV, or XGA video signals up to
230 feet (70 m).

Supports DDC and HDCP copy protection transmission — The transmitter and
receiver 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 DTP DVI 230 D transmitter and receiver also route unbalanced stereo
audio.

Supports CEC signal transmission
Wall-mountable enclosures
External 100 VAC to 240 VAC, 50-60 Hz, international power supply — Included with

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

power both devices.

Mounting the Transmitter or Receiver

ATTENTION: Installation and service must be performed by experienced personnel.

The DTP DVI 230 D transmitter and receiver can be installed in a two-gang electrical wall
box or with a mud ring, with a Decora wall plate cover (supplied).

The installation must conform to national and local electrical codes and to the size
requirements of the wall plate.

UL and Safety Guidelines

The following UL guidelines pertain to the installation of the Decora transmitters and
receivers into a wall or furniture.

• These units are not to be connected to a centralized DC power source or used beyond

their rated voltage range.

• These units must be installed in UL-listed junction boxes.

• These units must be installed with conduit in accordance with National Electrical Code.

Preparing the Site and Installing the Wall Box

Choose a location that allows cable runs without interference. Allow enough depth for
both the wall box and the cables. The box should be at least 3.0 inches (7.6 cm) deep
to accommodate the connectors and cables. Install the cables into the wall, furniture, or
conduits before installing the wall plate.

NOTE: The Decora units are very deep and have connectors on the back side.

Extron recommends a 2-gang junction box which has a depth of 3.0 inches
(7.6 cm).

DTP DVI 230 D Transmitter and Receiver • Installation and Operation 3

To install a new wall box, perform steps 1 through 9. If a suitable wall box is already
installed, perform steps 6 through 9 on the next page. UL listed wall boxes are
recommended.

1. If a wall box is not available to use for a template, see Decora Template Dimensions

on page 15 to create a template. If installing directly into furniture, cut out the center
portion of your template.

2. Place the wall box (or your template) against the installation surface, and mark the

opening guidelines.

3. Cut out the material from the marked area.

4. Insert the wall box into the opening. The rear connectors on the box or wall plate should

fit easily into the opening. Enlarge or smooth the edges of the opening if needed.

5. Secure the wall box with nails or screws, leaving the front edge flush with the outer wall

or furniture surface (see figure 2).

NOTES:

• If attaching the wall box to wood, use four #8 or #10 screws or 10-penny

nails. A minimum of 0.5 inch (1.3 cm) of screw thread must penetrate the
wood.

• If attaching the wall box to metal studs or furniture, use four #8 or #10

self-tapping sheet metal screws or machine bolts with matching nuts.

The DTP DVI 230 D is compatible with CAT 5e, 6, 6a, and 7 shielded twisted pair (F/UTP,

SF/UTP, and S/FTP) and unshielded twisted pair (U/UTP) cable.

Cable recommendations —
Extron recommends using the following practices to achieve full transmission distances up

to 230 feet (70 m) and reduce transmission errors.

• Use the following Extron XTP DTP 24 SF/UTP cables and DTP 24 connectors for the

best performance:

• XTP DTP 24/1000 Non-Plenum 1000’ (305 m) spool 22-236-03

• XTP DTP 24P/1000 Plenum 1000’ (305 m) spool 22-235-03

• XTP DTP 24 Plug Package of 10 101-005-02

• If not using XTP DTP 24 cable, at a minimum, Extron recommends 24 AWG, solid

conductor, STP cable with a minimum bandwidth of 400 MHz.

• Terminate cables with shielded connectors to the TIA/EIA T 568 B standard.

• Use no more than two pass-through points, which may include patch points, punch

down connectors, couplers, and power injectors. If pass-through points are required,
use CAT 6 or 6a shielded couplers and punch down connectors.

NOTE: When using CAT 5e and CAT 6 cable in bundles or conduits, consider the

following:

• Do not exceed 40% fill capacity in conduits.

• Do not comb the cable for the first 20 meters, where cables are straightened,

aligned, and secured in tight bundles.

• Loosely place cables and limit the use of tie wraps or Velcro®.

• Separate twisted pair cables from AC power cables.

WARNING: The two power cord wires must be kept separate while the power supply is

plugged in. Remove power before wiring.

ATTENTION:

• Always use a power supply supplied and or specified by Extron. Use of an

unauthorized power supply voids all regulatory compliance certification and may
cause damage to the supply and the end product. Unless otherwise stated, the
AC/DC adapters are not suitable for use in air handling spaces or in wall cavities.
The installation must always be in accordance with the applicable provisions of
National Electrical Code ANSI/NFPA 70, article 75 and the Canadian Electrical
Code part 1, section 16. The power supply shall not be permanently fixed to
building structure or similar structure.

• Power supply voltage polarity is critical. Incorrect voltage polarity can damage

the power supply and the unit. The ridges on the side of the cord (see figure 10)
identify the power cord negative lead.

• To verify the polarity before connection, plug in the power supply with no load and

check the output with a voltmeter.

• The length of the exposed (stripped) copper wires is important.

The ideal length is 3/16 inch (5 mm). Longer bare wires can short together.
Shorter wires are not as secure in the connectors and could be pulled out.

System Operation

After the transmitter, the receiver, and their connected devices are powered up, the system
is fully operational. If any problems are encountered, ensure all cables are routed and
connected properly.

NOTE: Ensure that the video source and display selected for the DDC are properly

connected to the transmitter and receiver pair, and that the transmitter, the receiver,
and the display have power applied before power is applied to the video source. If all
other devices are not turned on before the video source, the image may not appear.

Ground Loops

When installing the DTP DVI 230 D series products, be sure to avoid scenarios where the
ground potential differs greatly between the locations where the DTP transmitter and DTP
receiver are installed. Such situations can cause ground loops, which can result in image
drops, no image, or damage to the units. If such installations cannot be avoided, it is
necessary to isolate the ground between the DTP transmitter and receiver.

NOTES:

• Grounding DTP series units will disable analog audio transmission and the remote

power feature.

• Both DTP transmitter and receiver will need to be powered locally.

To eliminate a ground loop:

1. Remove all screws on the left, right, and top of both the DTP transmitter and receiver

units.

2. Remove the rear enclosure of each unit.

3. Locate and remove shunt jumpers at locations labeled JMP2 and JMP3 on both

transmitter and receiver (see figure 13 for jumper locations).

4. Replace the rear enclosures and screws.

5. Install units with an external power supply placed at each end.

6. Use UTP cable between the DTP transmitter and receiver. If STP cable has already been

installed and terminated, disconnect the shielding at one end to discontinue the ground
path.
