General

The Model MRX2EA4 printed circuit board assembly (PCBA) contains a frequency hopping spread spectrum
radio operating in the 902.4-927.6 MHz ISM frequency band. It also contains circuitry for electricity metering.
When the MRX2EA4 module is installed in a plastic housing it forms a complete electricity meter. 12
MRX2EA4 units are placed in a metal cabinet together to complete an MRX2EA4 system. Installations of
multiple MRX2EA4 meters comprise part of an Advanced Metering Infrastructure (AMI) system that utilizes a
proprietary network architecture and protocol devised by Elster Solutions.
