Abstract

A system for the configuration of power meters.

Claims

1. A power meter comprising:

(a) said power meter including an enclosure having an exterior;

(b) said power meter including a meter status observable from said exterior of said enclosure;

(c) said power meter including a settings status observable from said exterior of said enclosure;

(d) said power meter including a communications status observable from said exterior of said enclosure;

(e) said power meter including a phase status observable from said exterior of said enclosure;

(f) said power meter including a non-binary phase status observable from said exterior of said enclosure;

(g) said power meter including an input device that receives data in the form of data packets related to electrical characteristics of a least one load, where a data processor of said power meter determines (1) a baud rate based upon the frequency of data sampling by said power meter of said data packets among a plurality of predetermined baud rates, (2) a parity based upon bits of data sampling by said power meter of said data packets among a plurality of parities, and (3) a protocol based on cyclic redundancy bits of data sampling by said power meter of said data packets among a plurality of protocols of said received data.

2. The power meter of claim 1 wherein said meter status is a multi-colored light emitting device.

3. The power meter of claim 2 wherein an output color of green for said multi-colored light emitting device indicates normal operation.

4. The power meter of claim 2 wherein an output color of red for said multi-colored light emitting device indicates an error condition.

5. The power meter of claim 2 wherein an alternating red and green output for said multi-colored light emitting device indicates a firmware download.

6. The power meter of claim 1 wherein an on state of said settings status indicates that one of a user interface controls has been overridden through another setting.

7. The power meter of claim 1 wherein said communications status includes an indicator indicating an auto-baud mode which has not yet locked onto a baud rate, a parity, and a protocol.

8. The power meter of claim 7 wherein said communications status indicates a communication error.

9. The power meter of claim 8 wherein said communications status includes a framing error.

10. The power meter of claim 1 wherein said non-binary phase status including a light emitting device.

11. The power meter of claim 10 wherein said light emitting device for said non-binary phase status blinks indicating a phase angle.

12. The power meter of claim 11 wherein said light emitting device for said non-binary phase status blinks includes a plurality of lights.

13. The power meter of claim 12 wherein each of said plurality of lights relates to a different phase for said power meter.

14. The power meter of claim 12 wherein said baud rate, said parity, and said protocol are initialized to a previous such state.

15. The power meter of claim 12 wherein said baud rate, said parity, and said protocol are reacquired if such initialization results in a sufficient number of errors.

16. The power meter of claim 1 wherein said power meter first determines said baud rate, then after said power meter determines said baud rate said power meter determines said protocol.

17. The power meter of claim 16 wherein said power meter determines said protocol based upon cyclic redundancy bits.

18. A power meter comprising:

(a) said power meter including an enclosure having an exterior;

(b) said power meter including an input device that receives data in the form of data packets related to electrical characteristics of a least one load, where a data processor of said power meter determines (1) a baud rate based upon the frequency of data sampling by said power meter of said data packets among a plurality of predetermined baud rates, (2) a parity based upon bits of data sampling by said power meter of said data packets among a plurality of parities, and (3) a protocol based on cyclic redundancy bits of data sampling by said power meter of said data packets among a plurality of protocols of said received data.

19. The power meter of claim 18 further comprising a communications status observable from said exterior of said enclosure that includes an indicator indicating an auto-baud mode which has not yet locked onto a baud rate, a parity, and a protocol.

20. The power meter of claim 18 wherein said power meter first determines said baud rate, then after said power meter determines said baud rate said power meter determines said protocol.
