ABSTRACT:
The present invention achieves technical advantages as an AMR device and method of use having an optical transceiver adapted to read analog meter faces. The transceiver advantageously includes an optical receiver having an amplifier receiving signals from photodiodes and further including an automatic gain control. A gain of the optical receiver amplifier is programmable to compensate for parameters affecting the photodiodes in the optical receiver.
