Abstract

The invention regards a system and method for using a handheld programming device to configure a lighting control system wirelessly. In one embodiment, at least one device configured with a processing section is installed in the lighting control system. A communications receiver that is operable to receive a signal from the handheld programming device is also installed in the lighting control system, wherein the signal includes an instruction for configuring the lighting control system. Further, the signal is wirelessly sent from the handheld programming device to the communications receiver, and the instruction is transmitted from the communications receiver to a device in the system. The instruction functions to configure the lighting control system.

Claims

1. A method for replacing a ballast in a lighting control system that comprises a first ballast having a first unique identifier associated therewith and a bus supply interconnected by a communication bus, the method comprising the steps of:

providing the first ballast with a first ballast configuration setting;

storing in the bus supply first ballast electronic configuration information representing the first ballast configuration setting, and storing in the bus supply the first unique identifier;

removing the first ballast from the lighting control system;

installing a second ballast having a second unique identifier associated therewith in the lighting control system;

transmitting an instruction to the bus supply to configure the second ballast with the first ballast configuration setting;

correlating the second unique identifier with the first unique identifier; and

configuring the second ballast with the first ballast electronic configuration information stored in the bus supply.

2. The method of claim 1, wherein the first and second unique identifiers are serial numbers.

3. The method of claim 1, further comprising storing a short unique identifier that corresponds with each respective unique identifier so as to facilitate faster communication between the first and second ballasts, and the bus supply.

4. The method of claim 1, further comprising:

providing a third ballast having a third unique identifier associated therewith with a third ballast configuration setting;

storing in the bus supply the third ballast configuration information representing the third ballast configuration setting, and storing on the bus supply the third unique identifier;

removing the third ballast from the lighting control system;

installing a fourth ballast having a fourth unique identifier associate therewith in the lighting control system; and

transmitting an instruction to the bus supply to configure the fourth ballast with the third ballast configuration setting;

correlating the fourth unique identifier with the third unique identifier; and

configuring the fourth ballast with the third ballast configuration information stored in the bus supply.

5. The method of claim 1, wherein the step of transmitting comprises transmitting wirelessly the instruction by a handheld programming device.

6. The method of claim 5, wherein the instruction is transmitted via infrared or radio frequency communications.

7. The method of claim 1, further comprising flashing a lamp associated with the second ballast to represent that the second ballast has successfully replaced the first ballast.

8. The method of claim 1, wherein the configuration setting represents at least one of a high end trim, a low end trim, a fade time, a ballast burn-in state, an emergency intensity level setting, an intensity level to operate a ballast at in response to a photosensor registering a light input, an intensity level to operate a ballast at in response to an occupancy sensor registering an occupied or an unoccupied status, a time-out value, and an intensity level to operate a ballast at in response to a contact closure input terminal registering a closed status or an open status.

9. A system for replacing a ballast in a lighting control system that comprises a first ballast and a bus supply interconnected by a communication bus, the system comprising:

a first unique identifier assigned to the first ballast;

a first ballast configuration setting provided for the first ballast;

electronic configuration information stored in the bus supply and representing the first ballast configuration setting and the first unique identifier;

a second unique identifier assigned to a second ballast, wherein the second ballast is installed in the lighting control system and replaces the first ballast; and

wherein the bus supply is operable to use the first ballast configuration setting of the electronic configuration information to configure the second ballast.

10. The system of claim 9, wherein the first and second unique identifiers are serial numbers.

11. The system of claim 9, further comprising a short unique identifier that corresponds with each respective unique identifier.

12. The system of claim 9, further comprising:

a third unique identifier assigned to a third ballast;

a third ballast configuration setting provided for the third ballast;

electronic third ballast configuration information stored in the bus supply representing the third ballast configuration setting and the third unique identifier;

a fourth unique identifier assigned to a fourth ballast, wherein the fourth ballast is installed in the lighting control system and replaces the third ballast; and

wherein the bus supply is operable, in response to a transmitted instruction, to configure the fourth ballast with the third ballast configuration setting by correlating the fourth unique identifier with the third unique identifier, wherein the bus supply is operable to use the electronic third ballast configuration information to configure the fourth ballast.

13. The system of claim 9, further comprising a handheld programming device operable to transmit wirelessly the instruction.

14. The system of claim 13, wherein the handheld programming device is operable to transmit the instruction via infrared or radio frequency communications.

15. The system of claim 9, further comprising at least one lamp installed in the lighting control system that is operable to flash to represent that the second ballast has successfully replaced the first ballast.

16. The system of claim 9, wherein the first ballast configuration setting represents at least one of a high end trim, a low end trim, a fade time, a ballast burn-in state, an emergency level intensity setting, an intensity level to operate the first ballast at in response to a photosensor registering a light input, an intensity level to operate the first ballast at in response to an occupancy sensor registering an occupied or an unoccupied status, a time-out value, and an intensity level to operate the first ballast at in response to a contact closure input terminal registering a closed status or an open status.
