WILLIAMS SOUND IR T2-POE KT1 Power Over Ethernet
Introduction
The IR T2 is shipped with Williams Sound’s TFP 057 (48VDC power supply). The
IR T2 is also compatible with the Williams Sound POE 001 Power over Ethernet
transformer, and with most POE switches.
Note: The IR T2 is NOT compatible with POE+ power supplies unless they
are backwards compatible with POE standards.
Note: We cannot guarantee the audio quality of IR T2 units powered from a
third-party POE switch, as they may introduce noise into the system.
POE KT1
This kit should be used for applications using the power supply included with
the IR T2 (TFP 057). The kit includes:
- WCA 131
- WCA 133
POE KT2
This kit should be used for applications using POE 001 or a POE Switch. The
kit includes:
- WCA 131
- WCA 132
Using POE
POE is provided through a CAT5 or higher cable. Installers should carefully select the grade of CAT5 (or better) cable for the best quality. CAT5 cable provides many advantages:
- Available pre-terminated in various lengths, or terminated on site to the required length
- Available plenum rating, if required
- Available shielded for audio applications
Williams Sound has tested control and balanced audio configurations with up to
300 ft. [91 m.] of CAT5 cable. Environmental interference can limit the length
of cable depending on how it is being used. Unbalanced audio setups in excess
of 20 ft. [6 m.] of cable are not recommended.
CAT5 cable contains four twisted pairs of wires, two of which are used for
POE. Using Williams Sound’s passive POE injector kits (POE KT1 or POE KT2)
allows the installer to use the remaining two pairs of wire for one of the
following three options:
- 1 channel of balanced line level audio
- 1 or 2 channels of unbalanced line level audio
- RS-232 control and monitoring signal
If using 2 channels of balanced line level audio, control/monitoring, and power, POE KT1 or POE KT2 will need to be used along with an additional CAT5 cable. One CAT5 cable will be connected to the POE injector kit and provide power and control, while the other CAT5 cable will provide audio.

Cabling for Inputs
If using the POE 001 power over Ethernet injector, connect either the RJ-45
plug on the labeled LAN + DC .
Note that the WCA 132 can be plugged directly into the LAN
port, which may not leave enough of a cable run to connect to the audio
In all the figures below, check the color coding for the type of CAT5 cable
used to determine wire colors if terminating a CAT5 cable.
Input Wiring
Note: The figures below are shown using a WCA 133, but a WCA 132 can be
used with same wiring. In some cables, the yellow wire may be colored green.

Connecting Audio, Power and Control
Providing power, audio and control options simultaneously requires two CAT5
cable runs. To run the power and control, you will need either the POE KT1 or
POE KT2, depending on how you wish to power the device.
If you are using the provided power supply (TFP 057), connect the power to a
WCA 133 from POE KT1.
If you are using POE switch or power supply, connect the power to a WCA 132
from POE KT2.
When powering the IR T2, connect the WCA 131 to the CAT5 cable with the
powered WCA 132 or WCA 133. Connect the WCA 131 to the Power In and Control
inputs on the IR T2.
Run a separate CAT5 (or higher) cable connected to a balanced audio source on
one end. Connect the other end to the IR T2 following the wiring diagram
below.
Refer to the wiring diagrams throughout this document for your specific
configuration needs.
