Power and Wiring
With a single CAT5e or CAT6 cable you can both Power iPad and provide power and data to the Surface Mount Buttons bezel. A PoE Switch will provide the power and data using PoE 803.2af. But even if you aren't using a PoE Switch, you can use the iPort PoE Injector to inject power and pass data from a non-PoE Switch. Every Surface Mount with Buttons System ships with a PoE Splitter.
