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.

–Mobile and Handheld Mode. The module transmits a medium-powered RF message
every 15 seconds. In Mobile and Handheld Mode, the expected battery life is 20 years.
–(Optional) Hard-to-Read Mode. The module transmits a high-powered RF message
every 30 seconds. In Hard-to-Read Mode, the expected battery life decreases to 15
years in this mode. The Hard-to-Read Mobile Mode should only be used for
exceptionally hard to read applications (such as meters installed in sub-basements).
■Leak Detection and Reverse Flow Detection. Cellular 500Ws feature robust algorithms
that provide leak and reverse flow detection.
■(Optional) Leak Sensor
–The optional Leak Sensor analyzes water flow sound patterns to detect water leaks.
Leak sensor analysis data is uploaded to the mlogonline Network Leak Monitoring
online portal. Systems with optional Leak Sensor devices access leak information
through their utility-specific, secure mlogonline portal. For more information, see the
mlogonline Network Leak Monitoring System User Guide.
■(Optional) Telemetry devices
–An optional remote water disconnect valve provides water utilities with a non-intrusive
means of managing customer disconnects and reconnects that traditionally required
on-site visits. The remotely-controlled disconnect valve helps lower the utility's costs
by eliminating routine move-in/move-out service calls. For more information, see
Remote Disconnect Valve Installation on page 33.
Note: Remote water disconnect operation requires a module with enhanced
security enabled. To learn more about enabling enhanced security, see the Field
Deployment Manager (FDM)Tools Mobile Application Guide.

Security
Users have the option of enabling enhanced security in Cellular 500Ws. Itron Security
Manager (ISM) is a feature of the OpenWay Network that ensures that certain Cellular 500W
commands are controlled through secure radio communications between the handheld
computer or Mobile Collector and the Cellular 500W .
There are two fundamental security processes used in the OpenWaysystem to ensure
confidentiality and validity of secured commands.
■Authentication. Authentication is the process of confirming that an artifact is genuine or
valid. Authentication in the Cellular 500W is the process of verifying a request is from a
valid source and in its original form.
■Encryption. Encryption is the process of transforming information to make it unreadable
to anyone who does not have a valid security key. There are two types of encryption:
symmetric and asymmetric. Symmetric encryption uses a shared key to decrypt or encrypt
information. Asymmetric encryption uses a private key to encrypt and a public key to
decrypt. Data transmissions over the network are protected using AES-256 encryption.
Transmission Modes
The Cellular 500W is an IPv6 Wisun compliant device that operates in Mobile Mode or
Network Mode.
Mobile Mode
In Mobile Mode, the module transmits every nine seconds over multiple RF channels to report
on:
■meter register value
■cut cable or communication error event
■reverse flow (encoder version selected)
■system leak status
■low battery indicator
Network Mode
In Network Mode, the module reports four interrogation cycles daily. Each interrogation
collects six hours of 3,840 buckets of interval and event data. Interval data is configurable
from 1 minute to 1 hour (for example, 160 days of hourly data or 40 days of 15 minute data).
Interval options are 5, 15, or 30 minutes.

Note: Interval data configuration is dependent on the module's firmware version. See
Firmware Functionality on page 11 for more information.
The Cellular 500W also sends a local access beacon message every 60 seconds that allows
users to gather contingency readings locally when needed.
Caution: If you perform a switch to Network Mode or switch to Mobile Mode
operation, it results in a loss of interval data.
The Cellular 500W operates using FCC or ISED licensed spectrum defined by 3GPP ranging
from Band 4 (744-787 MHz) and Band 13 (1710-2155) operation 612054.
Operating Modes
The Cellular 500W has the following operating modes.
■Factory Mode
–Remote modules are shipped from the factory in Factory Mode.
–The module's transmitter is turned off.
–The module's receiver is bubbling-up to listen for a programming command.
–Remote modules will attempt to read the register every hour.
–Register Error Detected and Register Error alarm or event flags may be set when a
register is not connected.
–If the Cellular 500W reads a connected register, the module automatically moves to
Run Mode.
■Audit Mode
–Audit Mode reduces the normal read latency time associated with standard modes of
operation and is often used after initial installation.
–This mode is useful in network installations where the normal bubble rate is very slow.
–Audit Mode remains active for 30 days and then reverts to the initial programmed
mode.
–Audit Mode is intended to be used once.
■Run Mode
–Remote module normal operation mode.
–The remote module's transmitted message is dependent on its factory settings for
standard consumption + messages (SCM+).
–SCM+ remote module default bubble-up rate is 10 seconds.

■Quiet Mode
–Meter manufacturers can configure the Cellular 500W for Quiet Mode after
programming and direct mounting the Cellular 500W in a factory.
–The Cellular 500W is awakened from Quiet Mode and enters Run Mode in one of the
following ways:
•Counting two pulses. The pulses are counted internal to the Cellular 500W while it
is in Quiet Mode.
•Receiving a two-way command, such as a Read using FDM.
If a Cellular 500W installed in Quiet Mode is not bubbling up SCM+ messages, it may be due
to zero consumption on the Cellular 500W, such as a vacant or vacation home. Initiate a two-
way command (for example, perform a Read with FDM) before removing the unit.
Battery Life
The Cellular 500W is powered by a single non-replaceable, long-life lithium batteries and has
an expected battery life of 20 years, dependent on use case.
Low Battery
Cellular 500Ws include a low battery indicator that helps utilities proactively plan and manage
field module replacements.
Events and Alarms
The events and alarms available to a Cellular 500W vary based on the mode it is operating in.
Extended Alarm Flag
This is retrievable with two-way communication.
Register Error Flag
■The Register Error flag sets if the Register Error Detected flag is active for 24 hours.
■The Register Error Flag remains active for 40 days in Mobile Mode.
Register Error Detected
■Register Error Detected indicates that the Cellular 500W is not communicating with the
register/meter. The event or alarm flag automatically clears after the Cellular 500W
receives a successful read from the register.
Note: The Register Error Detected flag may be an indicator of a damaged register.
