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).

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.

NThe non-Decora®models do not input, transmit, receive, 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.

N• 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.

Figure1-1 —Typical transmitter andreceiverapplication

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.

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.
