Abstract
According to some embodiments a system may control connected modules within a lighting fixture. The system may comprise a power supply that includes a first input to receive AC power, a second input to receive a control signal, and an output to transmit DC power. A light emitting diode (LED) array may receive DC power from the power supply. A master control unit may receive DC power from the power supply. The master control unit may comprise a first control line to send a control signal to the power supply to control the LED array and a second control line to control one or more modules. The system may further comprises one or more connectors mounted to a circuit board where at least one of the one or more connectors is electrically coupled to the output of the power supply and the second control line.
