Patent ID: 7812543

Claim:
A lighting control system, comprising: a transceiver having a data processing unit, an interface circuit connected to the data processing unit, and a first plug that is connected to a first end of an interface cable having a first pin corresponding to an on/off signal, a second pin corresponding to a ground signal, a third pin corresponding to a voltage power signal that provides power to the transceiver, and a fourth pin corresponding to a dimming signal, the data processing unit having a computer readable medium encoded with a program for receiving a command signal from an external controller and for sending a control signal to the interface circuit, wherein the control signal corresponds to the command signal and the on/off and dimming signals are a function of the control signal; and a dimming ballast connected to a second end of the interface cable, wherein the dimming ballast is configured to provide a voltage to power the transceiver over the interface cable, and the transceiver is configured to provide the on/off and dimming signal to the dimming ballast over the interface cable; wherein the transceiver further includes a jack configured to relay the on/off and dimming signal control to a second transceiver.
