About the 100G Gas ERT Module
• 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 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 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 gas ERT modules.
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 DLS 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 DLS supports the security model found in the
ChoiceConnect solution for both reading and programming. If the 100G DLS 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).
