Note that this script uses the string “112233445566” as the first half of the 96-bit
key and the string “665544332211” as second half of the 96-bit key. Using a key
of “112233445566665544332211” is better than not using authentication, but it is
considered a weak key.
Device Upgrade Planning
To allow your street lighting network to be upgraded over time, you can download
an updated Street Light Bridge application (as Echelon releases application
updates) over the power line network. The application download uses the
standard ISO/IEC 14908-3 download protocol. See Upgrading Devices on page 65
for information about how to perform the application upgrade using the Segment
Controller Web pages.
The application download process includes the following steps:
• The Street Light Bridge detects the start of a download by a transition to
the applicationless state.
• The Segment Controller then downloads the application, which is stored
in onboard flash memory.
• After the download is complete, the Street Light Bridge firmware
computes a checksum of the downloaded application image to verify that
the download was successful. If the checksum fails, the Street Light
Bridge firmware sends a failure response to the “go unconfigured” request
that follows the computation of the checksum. In this case, you should
begin a new download for the application or contact Echelon Support.
