Lighting control interface techniques and corresponding circuitry are provided. The techniques include receiving a first signal potentially representative of a first lighting control signal, and receiving a second signal potentially representative of a second lighting control signal, and determining if either of the first and second signals complies with a first or second lighting control protocol. The lighting control signal may be applied to the same interface connector (regardless of the protocol), thereby eliminating the need for separate dedicated interface connectors. In some cases, the techniques further include determining that a dummy control signal is manifesting in the first and/or second signals, thereby indicating that no lighting control signal is being applied. Depending on the resulting determination, the techniques may include, for example, setting output lighting power according to a pre-established value, or according to the first or second lighting control protocol. |
