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.
