DTP DVI 4K 330 Transmitter and Receiver • Introduction 2
The DTP DVI 4K 330 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 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 4K 330 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.
Features
• 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 330
feet (100 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.

NOTES:
• If you have removed the ground jumpers (see Disconnecting the Ground
on page12) because of ground potential differences, the DTP DVI 330
cannot extend analog audio. No analog audio is output.
• The length of exposed wires is critical. The ideal length is 3/16 inch (5 mm).
• If the stripped section of wire is longer than 3/16 inch, the exposed wires
may touch, causing a short circuit.
• If the stripped section of wire is shorter than 3/16 inch, wires can be
easily pulled out even if tightly fastened by the captive screws.
• Do not tin the power supply leads before installing them in the connector.
Tinned wires are not as secure in the connector and could be pulled out.

DTP DVI 4K 330 Transmitter and Receiver • Installation and Operation 7
Supported cables —
The DTP DVI 330 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 330 feet (100 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
• XTP DTP 24P/1000 Plenum 1000’ (305 m) spool
• XTP DTP 24 Plug Package of 10
• 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.
Power supply wiring
NOTES:
• One power supply is included with the transmitter and normally can power both
units.
• If you have removed the ground jumpers (see Disconnecting the Ground on
page12)) because of ground potential differences, one DTP DVI 330 unit
cannot remotely power the other unit. Each unit requires a local power supply.

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 330 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).
• Transmitter — Six screws, two on each side and two on top
• Receiver — Eight screws, three on each side and two on top

4. Reinstall the covers on both units, securing them in place with the screws removed in
step 2.
5. Reinstall both units in their racks or other installation option (see Mounting the
Transmitter or Receiver on page10).
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7).
