Abstract

A solution for providing various types of encoder-receiver-transmitter (ERT) devices for use in corresponding types of automatic meter reading (AMR) systems that receive standard consumption messages (SCMs) from ERT devices. According to one aspect, the solution includes maintaining a set of records that associate each issued serial number with a corresponding configured ERT type. A new first ERT device of a first type is configured with a serial number in accordance with the set of records. The first ERT device may have a common serial number with another ERT device of a different type; but the first ERT device may not have a common serial number with any other ERT device of the first type.
