User's Manual

Itron 100G series gas ERT modules are radio-frequency (RF) devices designed to transmit meter data to an
RF meter reading device within transmission distance of the ERT module. The 100G gas ERT was designed
with a higher output power than earlier Itron gas ERT modules to achieve an increased RF transmission
distance. The 100G series gas ERT modules have greater output power to meet Itron mobile and fixed
network requirements. The first generation 100G gas ERT module offered high transmit power capability
which increased operational efficiency and reduced infrastructure costs. The 100G Datalogging 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) gas ERT module added improved network performance through a higher transmit power,
accomplished using increased antenna efficiency and more robust optimized messaging structures. Itron's
100G series gas ERT module 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.
Transmission Modes
The 100G series gas ERT module can be set to transmit in Fixed Network, Mobile and Handheld, or Hard to
Read Mobile and Handheld Mode.
Fixed Network Mode. The 100G 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 DLS 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 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 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.
(Optional) Hard to Read Mobile and Handheld Mode. The 100G transmits a high-powered RF
message every 30 seconds. Output power in this mode is 250 milliwatts or +24dBm; expected battery life
decreases to 15 years in this mode. The Hard to Read Mobile and Handheld Mode should only be used for
exceptionally hard-to-read applications (such as meters installed on roof tops or in sub-basements).
