User's Manual

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 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 can 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 100G series remote gas 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).
• Fixed Network Mode. The 100G series remote gas module transmits a high-powered network interval
message (NIM) RF message every five minutes. Output power in this mode is 500 milliwatts or +27 dBm.
Interspersed in the high power NIM, the 100G series remote gas module transmits a medium power RF
message at 10 milliwatts or +10 dBm every 60 seconds; expected battery life is 20 years.
• Mobile High Power Mode. The 100G series remote gas module transmits a high-powered RF message
every 60 seconds. Output power in this mode is 250 milliwatts or +24dbm; expected battery life is 20
years.
• Mobile and Handheld Mode. The 100G series remote gas module transmits a medium-powered RF
message every 15 seconds. Output power in this mode is 10 milliwatts or +10dBm; expected battery life is
20 years.
