About this Manual
This manual contains information about the Extron
DVI 201 Tx/Rx and HDMI 201 Tx/Rx transmitter and receiver
pairs, including how to install, operate, and confi gure them.
N
In this manual, the term "Tx/Rx" refers to either
product.
About the DVI 201 Tx/Rx and HDMI 201 Tx/Rx
The Extron DVI 201 Tx/Rx is a Digital Visual Interface (DVI)
transmitter/receiver set. The HDMI 201 Tx/Rx is a High
Defi nition Multimedia Interface (HDMI
set. The transmitter/receiver sets extend the usable distance of
DVI or HDMI digital video, and RS-232 control signals over two
Category (CAT) 5/5e/6/7 twisted pair (TP) cables. The video
and control signals can be transmitted up to 200' (60 m).

Figure 1-1 — Typical transmitter and receiver application
The transmitter and receiver pairs consists of a Tx transmitter
and an Rx receiver that can handle a single link of
DVI-D or HDMI digital video, depending on the model.
N
The Tx/Rx is comprised of the transmitter-receiver
pair. The transmitter and receiver cannot be purchased
separately.

Each pair ships with a single external desktop 12 V power
supply that accepts 100 to 240 VAC, 50 Hz or 60 Hz input. A
single power supply connected to either the transmitter or the
receiver can power both units through one of the TP cables that
link the units.
TP cable advantages
Twisted pair cable is much smaller, lighter, more fl exible, and
less expensive than coaxial or DVI 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.
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 Tx/Rx will not
work properly with this cable.
Serial communications
The RS-232 and/or Consumer Electronics Control (CEC)
communications are via a passive pass-through only; the
transmitter and receiver do not generate or respond to these
signals.
Transmission distance
The maximum distance is determined by the resolution of the
signal and the UTP cable that is used.
With CAT 5/5e/6 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 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 125' (38 m).
