Chapter 2 About the 100G Remote Gas ERT
Module
Itron 100G series remote ERT modules are radio-frequency (RF) devices designed to
transmit meter data to an RF meter reading device within transmission distance of the
remote ERT module. The 100G remote gas ERT module was designed with a higher output
power than earlier Itron remote gas ERT modules to achieve an increased RF transmission
distance. The 100G series remote gas ERT modules have greater output power to meet
Itron mobile and fixed network requirements. The 100G series product development
includes a generational progression of enhancements.
• The first generation 100G remote gas ERT module offered high transmit power capability
which increased operational efficiency and reduced infrastructure costs.
• The 100G Datalogging remote gas ERT module was enhanced to offer higher transmit
power with data logging capability (time-stamped hourly interval data) for both mobile and
fixed network applications.
• Itron's 100G Datalogging Fixed Network (DLN) remote gas ERT module added improved
network performance through a higher transmit power, accomplished using increased
antenna efficiency and more robust optimized messaging structures.
• The 100G DLS remote gas modules brings increased efficiency in SCM+ messaging and
adds enhanced network security. SCM+ messages expand the data fields within our
standard consumption message to offer added value. The enhancement of secure
communications provides greater protection for bubble-up and two-way messaging to
prevent unauthorized users from gaining access to the system.
• The 100G DLT Datalogging gas ERT module (100G DLT) is a hybrid in the Itron line of
100 Series radio frequency (RF) gas meter modules. The 100G DLT combines the circuit
board hardware of the 100G DLS module with the SCM messaging used in the 100G
DLN module. This allows utilities currently using the SCM messaging in the 100G DLN to
upgrade to the 100G DLT without the upgrades required for programming, enhanced
security, or meter reading. The 100G DLT does not offer the optional ISM enhanced
security capability or extended tamper information available in the 100G DLS.
The 100G remote module features tilt and cut cable-tamper reporting and security seals to
indicate physical tampering and minimize theft. Cut cable is reported when the cable is cut
or disconnected from the meter, instrument, or ERT module. 100G ERT module circuitry
senses an electrical current break to report a cut cable tamper event.
Transmission modes
The remote 100G ERT module can be set to transmit in fixed network, mobile and
handheld, hard to read mobile and handheld, or cellular solutions mode (fixed network
applications only).
