module executes the standard procedure to change date/time on the meter.
Power Outage/Restoration
When an outage occurs, the meter uses an early power failure signal to alert the
communication module to disconnect from the meterʹs power immediately. The
communication module saves critical module data to non‐volatile memory and
creates and sends a power outage message. This message includes the following
information:
•

communication module saves critical module data to non‐volatile memory and
creates and sends a power outage message. This message includes the following
information:
•
LAN ID
•
Outage time
•
Reboot count.
The module sends the message, then assists with routing other packets until the
back‐up energy source can no longer keep the radio alive. The time that this
energy source is available varies with several factors, including amount of data
packets being routed, environmental conditions and age of endpoint. Generally, a
hold‐up time of ~45 seconds is typical.
At restoration, the communication module first acquires network connectivity.
With network communications restored, the module sends a power restoration
message that includes details such as:

The communications module stores a history of up to the last five power outage
and restoration event pairs. The USC Host can request this data.

Supporting Passwords
The meter/module supports passwords provided by the utility.
Downloading Firmware
Enable meter firmware remotely via host or RadioShop. The module can remotely
initiate a self‐restart with communications enabled, if the downloaded firmware
causes a catastrophic functional failure. Once the module completely receives the
new code, it operates with the new code.

Encrypting Data
The UtiliNet Network currently supports use of one encryption key per network.
If you enable the S4e with encryption, the host must have a matching encryption
key. For more information about encryption in the UtiliNet Solution Center host,
see the UtiliNet Solution Center Operators Guide.

CONFIGURATION TABLES
The UtiliNet Module Configuration structure passes the data to configure the
module. It is used for both C&I and Residential applications. Detailed
information about the configuration tables is available in
