IR T2 - POE KT1 & KT2

POWER OVER ETHERNET WIRING GUIDE

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.

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

This kit should be used for applications using POE 001 or a POE Switch. The kit includes:

• WCA 131

• WCA 132

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.

Page 5 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.
