Williams Sound IR T2 User manual

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.
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 a POE Switch or POE 001. 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. 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 and 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

Cabling for Inputs
If using the POE 001 power over Ethernet injector, connect either the RJ-45 plug on the WCA 132 or a CAT5 cable directly to the port
labeled LAN + DC (See Figure 2).
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
source. If a longer cable run between the power source and the audio/control source is needed, a CAT5 cable can be run from the LAN
port instead. The CAT5 cable can be terminated as shown in Figures 7, 8 and 9 in the Output Diagrams section.
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: All Input Wiring figures are shown using a WCA 133, but a WCA 132 can be used with the same wiring.
