General

The Model RX2EA4F 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 RX2EA4F module is installed in a housing and meter base, it forms a complete electricity meter.
Installations of multiple REX2 meters comprise part of an Advanced Metering Infrastructure (AMI) system that
utilizes a proprietary network architecture and protocol devised by Elster Solutions.

Device specifications

NOTE: The meter only transmits on one network at a
time. Both are 25 channel FHSS networks.
