Power Line Communications
- This is for X10 but Insteon looks similar but is more complicated
- The 3 signal groups correspond to the zero crossing of each of the 3 phases of a 3 phase system
- Most US homes don't have 3 phase power, most have a split phase system (each 'phase' is 180 degrees out of phase with the other. This gives you 240V.
- X10 and Insteon use a 5v signal, UPB uses a 40v signal
