Landis+Gyr Confidential Information 98-1289 Rev AA 5
LAN ID
The LAN ID is a unique identifier for each Landis+Gyr endpoint. Landis+Gyr provides the LAN
address. You cannot change the radio’s LAN IDs.
Features and Functions
Endpoint Registration
The endpoint is automatically registered with the host system. No special tools are needed during
installation.
Admin packets are sent once each hour at a random time during the hour and play a crucial role in
the automatic discovery of a meter by the Landis+Gyr system. They tell what kind of meter the
module interfaces with, and other characteristics, such as the scaling constant, number of dials, and
the firmware version.
Admin packets include:
Communication and Retrieving Data
A microprocessor on the communications module (MFMM) reads energy data through the meter’s
serial interface and transmits the information to the head end system. Several different packet types
are sent.The most frequently sent packet contains the current rotational count and historical interval
data that is useful for load profiling and time-of-use metering. Another less frequently sent (Admin)
packet contains the current cumulative rotation count, useful for basic automatic meter reading
applications. An Admin packet is sent once hourly and contains the information listed in Table 2.
2 Landis+Gyr FCC ID Federal Communications Commission (FCC) Identification (ID)
number assigned to the Elster Multi-Function Meter Module for
use in the Elster Alpha+ meter.
3 Landis+Gyr LAN ID Identifies the Elster Multi-Function Meter Module to the
Landis+Gyr billing network (printed and barcoded).
