Introduction, cont'd
N
In this manual, the terms "DVI 201," "DVI 201 Tx,"
"DVI 201 Rx," "transmitter," and "receiver" refer to the
applicable unit(s) in either form factor, unless otherwise
specified.
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.
N
The transmitter and receiver pair works with unshielded
twisted pair (UTP) or shielded twisted pair (STP)
cables; but, to ensure FCC Class A and CE compliance,
STP cables are recommended.
N
Do not use Extron's UTP23SF-4 Enhanced Skew-
Free
A/V UTP cable to 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.
Control communications
The RS-232 and/or infrared (IR) communications are via a
passive 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/6/7 UTP cable, the Tx/Rx pair can transmit
and receive 720p and 1080i HDTV or XGA video signals up to
200' (60 m) and 1080p HDTV or UXGA video up to 100' (30 m).
With CAT 5/5e/6/7 STP cable, the Tx/Rx pair can transmit
and receive 720p and 1080i HDTV or XGA video signals up to
200' (60 m) and 1080p HDTV or UXGA video up to 125' (38 m).
N
The transmission distance varies greatly, depending on
the signal resolution, type of cable used, graphics card,
and display used in the system.
DVI 201 Tx/Rx • Introduction
1-4
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.
Long distance transmission —
CAT 5/5e/6/7 UTP cable — Accommodates 720p
and 1080i HDTV or XGA video over 200' (60 m), and
1080p HDTV or UXGA (1600 x 1200) over 100' (30 m).
CAT 5/5e/6/7 STP cable — Accommodates 720p and
1080i HDTV or XGA video over 200' (60 m), and
1080p HDTV or UXGA (1600 x 1200) over 125' (38 m).
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 pairs fully support long distance transmission
of the DDC and HDCP signals.
DDC routing to local or remote display — At the DVI 201 Tx
[non-Decora], the DDC or HDCP signal is directed to
either the local display or the remote display, depending
on which is more critical in receiving the signal.
Remote powering of transmitter or receiver — Only one power
supply is necessary to power both devices.
Control communications pass-through — Bidirectional RS-232
or IR control signals can be transmitted alongside the
DVI or HDMI 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" high, quarter rack width, metal enclosures (DVI 201 Tx
and DVI 201 Rx [non-Decora] only) — With low profile
enclosures, the transmitter and receiver 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.
