Abstract

The invention provides a method and circuitry for programming an AMR transmitter to operate in different modes. The device can be programmed as to any one or all of the following parameters: transmission power according to the physical environment of the installation; power level and modulation type for drive-by or fixed network application; and frequency of data transmission to conserve battery life. A laptop computer or other type of programming device communicates through an optical IR port to enter these parameters.

Claims
