About this Manual
This manual contains information about the Extron
DVI 201 family of Digital Visual Interface (DVI) video
transmitters (Tx) and receivers (Rx), including how to install,
operate, and configure them.
About the DVI 201 Transmitters and Receivers
The Extron DVI 201 is a family of DVI transmitters and
receivers, in enclosures that support different mounting options.
A transmitter and receiver pair extends the usable distance of
DVI digital video and RS-232 control signals over two Category
(CAT) 5/5e/6 unshielded twisted pair (UTP) or shielded twisted
pair (STP) cables. The DVI 201 A D transmitter and receiver also
route audio, but not on the TP link. The video and control (and
audio, if applicable) signals can be transmitted up to 200' (60 m).

Figure 1-1 — Typical transmitter and receiver application
A DVI 201 system consists of a transmitter (Tx) and a receiver
(Rx). The pair can handle a single link of DVI-D digital video
and a bi-directional RS-232 link. The DVI 201 A D also converts
a computer audio input into balanced or unbalanced stereo
audio output.

There are two subsets of transmitters and receivers in two
different enclosures or form factors:
•
DVI 201 Tx/Rx — These 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, or to a
projector pole. The transmitter in this form factor has a
local monitor output.

or output audio.
DVI 201 A D Tx/Rx — These units are housed in
•
enclosures that can be mounted in UL standard wall boxes
with Decora-style face plates. These units also convert
computer level audio to balanced or unbalanced stereo
audio.

•
A non-Decora transmitter or receiver is partially
compatible with a Decora receiver or transmitter.
A mixed form factor system can transmit and receive
•
video and RS-232 communications.
A mixed form factor system cannot handle audio,
•
as the non-Decora models do not input, transmit,
receive, or output audio.

The units can be purchased as a pair (of the same form factor)
or individually. Each purchased pair and each individual
transmitter is shipped with a single external desktop 12 VDC
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.
