4– Felt Feet
The TAV21 is a device that will send a standard composite video and analog audio signal over a long distance
using CAT-5 cable. A RAV20 module is required to convert the CAT-5 cable back to RCA to use as an input on
a preamp or receiver. When in use with a RAV20, power can be transmitted to the RAV20 for up to 500 feet
total. When in use with over 500 feet a 12VDC power source is needed (supplied).
1. Dual Box and Decora Chassis Configuration - The TAV21 is shipped default as a floor box design (F) for
use on a shelf , mounting behind a rack or even next to the source. The TAV21 may be configured for use in a
decora wall plate by removing the screws of the chassis and extracting the decora module assembly.
2. RCA Input - Audio and video input connectors using gold plated RCA connectors for minimal signal loss and
degradation. The conversion module uses this input as the source of video that is to be converted to RJ45.
3. 12V DC Input— Connect to an external DC power source (adapter included).
4. Output 1 and 2 - RJ45 CAT-5 video output. Two outputs are available to send to up to two RAV20 modules
for up to 1000 feet total.
Video Output 1 and 2
The TAV21 module provides two outputs to send up to two RAV20 modules. Simply connect
the output from the TAV21 to the Master Input on the RAV20. The total CAT-5 cable run
cannot exceed 1000 feet. ALL TAV21 modules must each be individually powered and all
RAV20 modules will be powered from the TAV21 up to 500 feet total. When using a distance
over 500 feet total or when using the Slave Output feature on the RAV20, all modules includ-
ing the TAV21 and all RAV20 must be individually powered.

CAT5 Audio/Video Drive Pinout
CAT-5 RJ45 pinouts use the T568B
standard. See the figure at left. Each
color twisted pair carries the differen-
tial audio/video signal with pin 7 and 8
sending power for up to 500 feet. Use
of other CAT-5 connection standards
may result in increased crosstalk
between signals with associated audio
and video degradation.
The RAV20 modules will be powered from the TAV21 up to 500 feet total. When using a distance over
500 feet total, all modules including the TAV21 and all RAV20 must be individually powered. When
using the SLAVE output feature ALL RAV20 and TAV21 modules must be externally powered.
CAT-5 T568B Standard
The RAV20 module is meant to be paired with the TAV21 for use when transmitting audio and video over CAT-
5 for up to 1000 feet. The TAV21 is used for transmitting the audio and video signal from RCA to CAT-5 and
the RAV20 is used for transmitting the audio and video signal from CAT-5 back to RCA. Below is an example
when using a TAV21 and RAV20 for transmitting an audio and video signal from a dedicated source to a CT
product.
