What Are System Upgrades?
There are three kinds of upgrades you can perform on a concentrator:
• The concentrator firmware
• The IWR radio firmware
• The IWR radio DCW.
Accessing a Concentrator for Programming
There are two ways to access a concentrator for upgrading:
•Over the air
• Directly via cable (About Programming and Diagnostic Cables, for more information).
Upgrading a Concentrator Over the Air (OTA)
You can remotely download firmware to the concentrator via a command window from your PC.
You must have control-level user access to the host to perform this procedure.
About the Image File
Landis+Gyr Customer Operations manages upgrades to firmware. Landis+Gyr notifies you when
there is a new release of firmware and makes the file available. To upgrade firmware, load the
concentrator with a new “image.bin” file. Contact Customer Operations at
ëçäìíáçåëìééçêíKå~]ä~åÇáëÖó êKÅçã for more information or to obtain the latest version of the
firmware.
The download application utility runs on the host backend via a process called Live System update
(LSU). The host connects over the air (OTA) to the concentrator. The host automatically:
1. Sends the new firmware information to the concentrator.
2. Polls the concentrator to verify that the download is complete.
3. Disconnects when the download is complete.
