Abstract

A utility meter adapted to communicate with a device external to the utility meter comprises a meter housing, a first port, a second port and a processor. The first port is adapted to receive signals transmitted from outside the meter housing. The second port is connected to a communications module associated with the meter. The communications module is adapted to communicate with the device external to the utility meter. A processor is connected to the first port and the second port. The processor is configured to pass signals received at the first port to the communications module through the second port.

Claims

1. A utility meter adapted to communicate with a device external to the utility meter comprising:

a meter housing;

a first port and a second port provided in the utility meter, the first port adapted to receive signals transmitted from outside the meter housing;

a communications module connected to the second port, the communications module adapted to communicate with the device external to the utility meter; and

a processor connected to the first port and the second port, the processor configured to pass signals received at the first port to the communications module through the second port.

2. The utility meter of claim 1 wherein the first port provides a first means for receiving signals and the second port provides a second means for receiving signals, the first means for receiving signals different from the second means for receiving signals.

3. The utility meter of claim 1 wherein the first port is an optical port configured to receive optical signals transmitted from outside the meter housing.

4. The utility meter of claim 1 wherein the communications module is an automatic meter reader module.

5. The utility meter of claim 1 wherein the communications module is provided within the meter housing.

6. The utility meter of claim 1 wherein the processor is configured to pass signals received from the first port to the second port without parsing the signals received from the first port.

7. The utility meter of claim 1 wherein the signals received at the first port include configuration signals for the communications module.

8. The utility meter of claim 7 wherein the configuration signals are intended to set communication parameters within the communications module.

9. The utility meter of claim 8 wherein the communication parameters include at least one communication parameter selected from the group consisting of baud rate, data word length, and stop bits.

10. The utility meter of claim 7 wherein the configuration signals include firmware updates for the communications module.

11. The utility meter of claim 1 wherein the communications module includes a configuration port that is not connected to the second port.

12. A utility meter comprising:

a) a first port;

b) a second port;

c) a communications module connected to the second port;

d) a processor connected to the first port and the second port, wherein the processor is configured to operate in a first mode where the processor delivers metrology data to the communications module through the second port and a second mode where the processor passes configuration signals received at the first port to the communications module through the second port.

13. The utility meter of claim 12 wherein the first port is an optical port configured to receive signals transmitted outside of the utility meter.

14. The utility meter of claim 12 wherein the processor does not parse the configuration signals from the first port when passing the configuration signals to the second port.

15. The utility meter of claim 12 wherein the communications module is an automatic meter reader module.

16. The utility meter of claim 12 the configuration signals deliver communication parameters to the communication module, the communication parameters including at least one parameter selected from the group consisting of baud rate, data word length, and stop bits.

17. The utility meter of claim 12 further comprises a meter housing, wherein the communications module is provided within the meter housing.

18. A method of operating a utility meter including a first port and a second port, the first port configured to receive signals transmitted outside of the utility meter and the second port connected to a communications module, the method comprising:

a) delivering metrology data to the communications module through the second port;

b) sending the metrology data delivered to the communications module to a communications network; and

c) passing configuration signals received at the first port to the communications module through the second port, wherein the communications module is configured using the configuration signals.

19. The method of claim 18 wherein the configuration signals are optical signals received at the first port and converted into electrical signals passed to the second port.

20. The method of claim 18 wherein the utility meter comprises a microprocessor operating in a first mode when the metrology data is delivered to the communications module through the second port and operating in a second mode wherein the configuration signals are passed to the communications module through the second port, wherein metrology data is not delivered to the communications module when the microprocessor operates in the second mode.
