Abstract
A transmitter apparatus and a ballast/driver receiver apparatus are presented for transmitting control information through a lighting system power line connection to a ballast or driver in which the transmitter selectively interrupts power delivery in select AC line power cycles to indicate data of a first binary state an uninterrupted power cycles indicate a second binary state with the receiver decoding the message data bits of different binary states based at least partially on the interruptions.
