The TCV31 is a video conversion module for use with converting differential analog video pairs to a CAT-5
cable for distances up to 1000 feet. The TCV31 requires a 12VDC external power source (supplied). To
convert the signals from the TCV31 module from CAT-5 to a standard component video signal, a RCV30 is
needed.
1. Dual Box and Decora Chassis Configuration - The TCV31 is shipped default as a floor box design (F)
for use on a shelf, mounted behind a rack or even next to the source. The TCV31 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 - Component 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 RCV30
modules for up to 1000 feet total.
Video Output 1 and 2
The TCV31 module provides two outputs to connect to RCV30 modules. Simply connect the
output from the TCV31 to the Master Input on the RCV30. The total CAT-5 cable run cannot
exceed 1000 feet. ALL TCV31 modules must each be individually powered and all RCV30 modules will be powered from the TCV31 up to 500 feet total. When using a distance over 500 feet
total or when using the Slave Output feature on the RCV30, all modules including the TCV31 and
all RCV30 must be individually powered.

powered using an external power source.
Rear Panel Decora and Box Configuration Summary
CAT5 Audio/Video Drive Pinout
CAT-5 RJ45 pinouts use the T568B standard.
See the figure at left. Each color twisted pair
carries the differential component 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.
CAT-5 cable allows differential video runs of up to 1000 feet. The TCV31 converts signals from RCA to RJ-45
and allows direct connection to RCV30 modules for use in converting the video signal back to RCA. The TCV31
allows both decora wall plate and stand alone box configuration. The diagram below shows the TCV31 connected
from RCA to CAT-5 termination with the RCV30 from CAT-5 to RCA video conversion modules to the Zone C
dedicated input on a CT Receiver.
Connection to an RCV30
The TCV31 modules must each be individually powered and all RCV30 modules will be powered from
the TCV31 up to 500 feet total. When using a distance over 500 feet total or when using the Slave Output
feature on the RCV30, all modules including the TCV31 and all RCV30 must be individually powered.
