Figure 1. Typical Transmitter and Receiver Application
The DTP DVI 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.
DTP DVI 230 Tx/Rx Transmitter and Receiver • Introduction 1

Features

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 DVI video.
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.
NOTE: Do not use Extron UTP23SF‑4 Enhanced Skew‑Free AV UTP cable or
STP201 cable to link the transmitter and receiver. The DTP DVI 230 Tx/Rx does not work properly with these cables.
Control Communications
The RS‑232 and IR communications are a passive pass‑through only. The transmitter and receiver do not generate or respond to the RS‑232 and IR communication signals.
Transmits single link DVI signals over a single STP or UTP cable — Standard twisted pair cables provide an economical, easily installed cable solution.
Long distance transmission — Extends video, audio, and control signals 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 DVI signal, so that the remote display can be controlled without the need for additional cabling.
Supports Consumer Electronics Control (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 — One power supply is included with the transmitter.
Remote powering of transmitter or receiver — Only one power supply is normally necessary to power both devices.

Mounting the Units

Mounting instructions can be found in Mounting the Transmitter or Receiver on page 10. Compatible optional hardware is listed on the Extron website (www.extron.com).
ATTENTION:
• Installation and service must be performed by authorized personnel only.
• Avoid ground potential differences between the transmitter and receiver installation
sites, which can lead to equipment damage or a missing or unstable picture. If a potential difference cannot be avoided, remove the ground connection between the units and locally power both units (see Disconnecting the Ground on page 11). In this configuration, the DTP DVI 230 cannot extend analog audio and each unit requires a local power supply.

The DTP DVI 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 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 these pass‑through points are required, use CAT 6 or 6a shielded couplers and punch down connectors.
NOTE: When using CAT5e and CAT6 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.

• Mounting the Transmitter or Receiver
• Disconnecting the Ground

Mounting the Transmitter or Receiver

ATTENTION:
• Installation and service must be performed by authorized personnel only.
• Avoid ground potential differences between the transmitter and receiver installation
sites, which can lead to equipment damage or a missing or unstable picture. If a potential difference cannot be avoided, remove the ground connection between the units and locally power both units (see Disconnecting the Ground on the next page).
The 1‑inch high, quarter rack width DTP DVI 230 transmitter or receiver can be placed on a table, mounted in a rack, or mounted under a desk or table. The receiver can also be mounted on a projector bracket.

Tabletop Use

Affix the included rubber feet to the bottom of the unit and place it in any convenient location.
Mounting kits
Mount the unit using any optional compatible mounting kit listed on the Extron website (www.extron.com), in accordance with the directions included with the kit. For rack mounting, see UL Rack-Mounting Guidelines on the next page.
DTP DVI 230 Tx/Rx Transmitter and Receiver • Reference Information 10
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 (as suggested by a missing or unstable picture), remove the ground connection between the units as follows:
NOTE: Once you have removed the ground jumpers, the DTP DVI 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. Slide
the covers forward slightly and lift them off both units (see figure 9).
