Abstract

A processing circuit for providing electronic photosensor information over a communication link. The processing circuit comprises a photosensor input circuit adapted to be directly coupled to a photosensor for receiving the electronic photosensor information from the photosensor. Further, a communication port is provided that allows for transmitting and receiving messages over the communication link. Moreover, a processor is provided that is coupled to the photosensor input circuit and the communication port. The processor determines whether the processor is operating in a default configuration, and broadcasts the electronic photosensor information on the communication link if the processor is operating in the default configuration.

Claims

1. A method for providing electronic photosensor information over a communication link, the method comprising the steps of:

providing a photosensor input circuit adapted to be directly coupled to a photosensor for receiving a control signal from the photosensor;

providing a processor coupled to the photosensor input circuit;

providing a communication port coupled to the processor for allowing the processor to transmit and receive messages over the communication link;

receiving at the photosensor input circuit the electronic photosensor information from the photosensor;

determining in the processor whether the processor is operating in a default configuration; and

broadcasting the electronic photosensor information on the communication link if the processor is operating in the default configuration.

2. The method of claim 1, wherein the step of broadcasting the electronic photosensor information further comprises broadcasting the electronic photosensor information on the communication link if the processor has not been commissioned.

3. The method of claim 1, wherein the step of broadcasting the electronic photosensor information further comprises broadcasting the electronic photosensor information on the communication link if the processor has not been programmed with an address.

4. The method of claim 1, wherein the default configuration comprises an out-of-box mode.

5. The method of claim 1, further comprising the step of:

connecting the communication link to a network of DALI devices.

6. The method of claim 1, further comprising the step of:

connecting the communication link to a DALI ballast.

7. The method of claim 1, further comprising the step of:

providing the photosensor input circuit, the communication circuit, and the processor in a ballast;

wherein the photosensor is coupled directly to the ballast.

8. The method of claim 1, further comprising the steps of:

processing the electronic photosensor information received from the photosensor; and

controlling a lamp in response to the electronic photosensor information.

9. The method of claim 1, further comprising the steps of:

processing digital messages received via the communication link; and

controlling a lamp in response to the received digital messages.

10. The method of claim 1, further comprising the step of:

storing the electronic photosensor information in a memory.

11. A processing circuit for providing electronic photosensor information over a communication link, the processing circuit comprising:

a photosensor input circuit adapted to be directly coupled to a photosensor for receiving the electronic photosensor information from the photosensor;

a communication port that allows for transmitting and receiving messages over the communication link; and

a processor coupled to the photosensor input circuit and the communication port;

wherein the processor determines whether the processor is operating in a default configuration, and broadcasts the electronic photosensor information on the communication link if the processor is operating in the default configuration.

12. The processing circuit of claim 11, wherein the processor broadcasts the electronic photosensor information on the communication link if the processor has not been commissioned.

13. The processing circuit of claim 11, wherein the processor broadcasts the electronic photosensor information on the communication link if the processor has not been programmed with an address.

14. The processing circuit of claim 11, wherein the default configuration comprises an out-of-box mode.

15. The processing circuit of claim 11, wherein the communication circuit comprises a DALI communication circuit and the communication link comprises a DALI communication link connected a network of DALI devices.

16. The processing circuit of claim 11, wherein the communication circuit comprises a DALI communication circuit adapted to be coupled to a DALI ballast.

17. The processing circuit of claim 11, wherein the processor comprises a microprocessor.

18. The processing circuit of claim 11, wherein the processor processes the electronic photosensor information received from the photosensor, and controls a lamp in response to the electronic photosensor information.

19. The processing circuit of claim 11, wherein the processor processes digital messages received via the communication link, and controls a lamp in response to the received digital messages.

20. The processing circuit of claim 11, wherein the processor includes memory for storing the electronic photosensor information.
