Note that my MITS DLP tv does not properly trigger a Xantech power sense unit so I resorted to using System.setGlobal() for my TV and Power Sense for my Denon receiver.

My actual setup looks at both the Global and the Power Sense and calculates via bitwise operations, a value between 0 and 3, based upon which value, I execute 1 of 4 different macros.

0 = Both Off // Do 2 progress bar sequences powering on TV followed by Receiver.
1 = TV Off, Receiver On - Do single progress bar sequence for TV.
2 = TV On, Receiver Off - Do single progress bar sequence for Receiver.
3 = TV On, Receiver On - Simply jump to final page.
