About the 100G Series Gas ERT Module
• (Optional) Hard to Read Mobile and Handheld Mode. The 100G series remote gas module 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).
• Itron Cellular Solutions (ICS) Mode. The 100G DLS module is compatible with the Itron Cellular
Solution and can be programmed for optimum operation with FDM Endpoint Tools Enhanced. In ICS
mode, the 100G DLS transmits a high-powered RF network interval message (NIM) every five minutes.
Output power in this mode is 500 milliwatts or +27 dBm. Interspersed in the high power NIM, the 100G
transmits a medium power RF message at 10 milliwatts or +10 dBm every 60 seconds; expected battery
life is 20 years.
Note ICS mode is for fixed network application only. ICS is optimized to work with the ICS
communications module in Itron’s electric meter. The 100G DLS must be in a full security mode to work
with ICS. This is not part of the ICS mode, but is a system level requirement.
An FCC license is not required to read 100G series remote gas module.
100G DLS ERT Module and Itron Security Manager
The 100G DLS ERT module is a component of Itron's ChoiceConnect system. ChoiceConnect system
enhanced security, provided by Itron Security Manager (ISM), applies to the RF communications between the
handheld computer, Mobile Collector, or Fixed Network system and the ERT module. ISM is available in the
100G DLS module only.
There are two fundamental security processes used in the ChoiceConnect system to ensure system
communication confidentiality and validity.
• Authentication. Authentication is the process of confirming that an artifact is genuine or valid.
Authentication in the 100G DLT remote gas ERT module 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.
As a component of the Itron ChoiceConnect solution, the 100G DLT remote gas ERT module supports the
security model found in the ChoiceConnect solution for both reading and programming. If the 100G DLT
remote gas ERT module modules are shipped without ChoiceConnect enhanced security enabled (ready to
secure), the utility can—at a later date—configure the ERT modules for ISM enhanced security.
Note Enabling or working with Itron ISM enhanced security requires FDM Endpoint Tools Enhanced.
Enabling 100G DLS ERT Module Security
When 100G DLS ERT modules ship from an Itron factory, each module contains utility factory keys. The
presence of these utility factory keys does not enable the enhanced security; the installer enables the enhanced
100G DLS security at the time the ERT module is deployed or at a later time using an Itron programming
device, Field Deployment Manager Endpoint Tools Enhanced, and programming commands. Initial key
exchange commands are secured using the utility factory keys. For more information about programming the
100G DLS ERT module for security, see the FDM Endpoint Tools Mobile Application Guide (TDC-0934).
