Introduction
The Cellular 500W Remote Module (ECW-1700-002) is a cellular radio frequency transmitting
modules that attaches to water registers or meters to collect consumption usage, event, and
alarm data. It is an IPV6-compliant endpoint designated to communicate over the Itron’s
OpenWay multi-purpose IoT solution: Network or the legacy ChoiceConnect™ Mobile
platform.
The Cellular 500Ws ship from the factory in Factory Mode, which prevents unwanted radio
transmissions during transit. After installation and programming, the remote modules acquire
and transmit meter or register data in accordance with the selected remote module parameter
settings. The Cellular 500Ws support protection for a variety of meter manufacturer's
registers. Refer to the Water Meter and Telemetry Module Compatibility Matrix for the list of
supported meters and registers.
Cellular 500Ws feature the following capabilities:
Datalogging. In Network Mode, the Cellular 500W provides 3,840 buckets of interval data
configurable from 1 minute to 1 hour (for example, 160 days of hourly data or 40 days of 15
minute data).
Note: Interval data functionality is dependent on the module's firmware version. For
more information, see Firmware Functionality on page 11.
In Mobile Mode, the module provides 960 buckets of hourly interval data and can be set to
transmit in Mobile and Handheld Mode, Mobile High Power Mode, or Hard-to-Read Mode.
Mobile High Power Mode. The module transmits a high-powered RF message every
60 seconds. In Mobile High Power Mode, the expected battery life is 20 years.
