Theory of Operation
The Gridstream RF Enhanced Elster A3 module is an electric endpoint with 900MHz Gridstream
and ZigBee communications on a single PCB. This product will be integrated into the Elster A3
meter. The following figure shows the high-level block diagram of the module. Each functional
block is described in the following sections.
Figure 1 - 3. Block Diagram
Pump Period Snap Read
Snap Reads will be delivered at a pseudo-random time, which will occur in
the first X hours of each day. X is the value that is provided here. It will default
to 2. The process is: this value, which is in hours, will be converted to
minutes. The LAN ID will be mod-ed with this minute value, and the result will
be the minute of the day that the self read is transmitted.
User ID 2 byte User ID used while running ANSI Logon Service
Logon User 10 byte User Name that is used while running the ANSI Logon Service
Security Password The full 20 bytes are required.
Sustained Outage
Duration
Defines the number of seconds after which an outage will be classified as
sustained. If less than this amount, the outage is momentary. A value of zero
will cause all outages to be considered "sustained".
Max Meter Time Drift
The number of seconds that the meter clock can drift from the radio clock,
after which an alarm is triggered.
Meter Time Read Period
The number of seconds that the meter clock can drift from the radio clock,
after which an alarm is triggered.
GMT Offset The GMT Offset in 15 minute increments. Signed.
