Claim 16:
17. A method to power and control a plurality of lighting modules, each lighting module including one or more lights and being serially addressable over a two-wire communication network, the method comprising:
with a power supply that includes a rectifier circuit and a bridge circuit,
receiving a power signal;
receiving command and address data that includes an address of a first lighting module and a command to be performed by the addressed lighting module;
forming a rectified power waveform; and
passing or inverting the rectified power waveform to provide, to the two-wire communication network, a data encoded power signal that is responsive to the command and address data;

monitoring a current of the power signal;
receiving, after the data encoded power signal is sent over the two-wire communication network, an indication of the monitored current;
comparing the received indication of the monitored current with a threshold value; and
based on the comparison, determining that the first lighting module responded to the command.
