User Guide Owner's manual
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.
NOTE: The 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.
NOTES: •  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 transmit and receive 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, 50-60 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.
NOTE: In this manual, the terms “DVI 201,” “DVI 201 Tx,” “DVI 201 Rx,” 
“transmitter,” and “receiver” refer to the applicable unit in either form factor, 
unless otherwise specified.
