Figure 1. Typical Transmitter and Receiver Application

DTP HDMI 230 Tx/Rx Transmitter and Receiver • Introduction 2
The DTP HDMI 230 Tx/Rx 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. The receiver can
also be mounted on a projector bracket.
The 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 TP cable that carries HDMI video.
TP Cable Advantages
Twisted pair cable is much smaller, lighter, more flexible, and less expensive than coaxial
or HDMI 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.
Control Communications
The RS-232 and IR communications are via a passive pass-through only. The transmitter
and receiver do not generate or respond to the RS-232 and IR communication signals.
Features
Transmits single link HDMI signals over a single STP or UTP cable — Standard
twisted pair cables provide an economical, easily installed cable solution.
Long distance transmission — Up to 230 feet (70 m)
Supports Display Data Channel (DDC) transmission — The transmitter and receiver
pair fully supports long distance transmission of the DDC signals.
Control communications pass-through — Bidirectional RS-232 and IR control signals
can be transmitted alongside the HDMI signal, so that the remote display can be controlled
without the need for additional cabling.
Supports CEC signal transmission
1-inch high, quarter rack width, metal enclosures — With low profile enclosures, the
transmitter and receiver can be discreetly installed in locations such as behind a plasma or
LCD flat-panel display.
External 100 VAC to 240 VAC, 50-60 Hz, international power supply — Included with
the transmitter
Remote powering of transmitter or receiver — Only one power supply is normally
necessary to power both devices.

properly with these cables.
Twisted pair recommendations
Supported cables —
The DTP HDMI 230 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 Extron XTP DTP 24 SF/UTP cable for the best performance. 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 these pass-through points are
required, use CAT 6 or 6a shielded couplers and punch down connectors.
NOTE: When using CAT 5e or 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.

DTP HDMI 230 Tx/Rx Transmitter and Receiver • Installation and Operation 8
Terminating shielded cable
The Tx includes two shielded RJ-45 connectors and a length of self-adhesive shielded tape
that you can use to make the STP cables to connect the transmitter and receiver.
NOTE:Extron supplies the connectors and the shielded tape. You must supply the
CAT 5e, CAT 6, or CAT 6a STP cable.
Terminate the STP cable as follows:
1. Peel back the cable shielding (see figure 6) from the end of the cable the length of the
RJ-45 connector body (approximately 7/8 inch [2.2 cm]) and fold it back.
Peel back shield and
fold back.
Figure 6. Peeling Back the Cable Shielding
2. Cut away and discard the clear cellophane inner wrapper from the end of the cable
back to the folded-over cable shielding.
3. Peel the backing off the self-adhesive shielded aluminum tape and wrap it around the
folded-over cable shielding, slightly overlapping the beginning of the tape (see figure 7).
Aluminum Tape Wrap tape around folded foil shielding.
Slightly overlap.
Cut and save the excess tape
for other connectors.

DTP HDMI 230 Tx/Rx Transmitter and Receiver • Reference Information 12
UL Rack-Mounting Guidelines
The following Underwriters Laboratories (UL) requirements pertain to the installation of the
unit into a rack.
• Elevated operating ambient temperature — 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 (TMA = +122 °F, +50 °C) specified
by Extron.
• 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.
• Mechanical loading — Mounting of the equipment in the rack should be such that a
hazardous condition is not achieved due to uneven mechanical loading.
• 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.
• 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 use of power strips).
Disconnecting the Ground
If you cannot resolve a ground potential difference between the transmitter and receiver
installation sites, remove the ground connection between the units as follows:
NOTE: Once you have removed the ground jumpers, the DTP HDMI 230 cannot
extend analog audio and one unit cannot remotely power the other. No analog audio
is output and each unit requires a local power supply.
1. Disconnect any cables and remove the transmitter and receiver from any rack or other
installation option.
2. Remove and retain the screws securing the covers to the transmitter and receiver. Lift
the covers off both units (see figure 12).
• Transmitter — Six screws, two on each side and two on top
• Receiver — Eight screws, three on each side and two on top

5. Reinstall both units in their racks or other installation option (see Mounting the
Transmitter and Receiver on page 11).
6. If you are using shielded cable, disconnect the cable shield from the connector at
either end of the cable.
7. Obtain a second 12 V power supply (one supply is provided with the transmitter and
normally powers both units), and locally power both units (see Power supply wiring
on page 9).
