After determining the appropriate model and firmware version, the authorization code (auth-code) is issued.
The auth-code is required to unlock the features on the new model type.
To upgrade to a new model with the same firmware version, use the
AUTH
command with the issued auth-
code, as outlined in
To upgrade to a new model with a new firmware version, the new firmware needs to be loaded into the OEM7
receiver. For instructions, refer to
Updating or Upgrading Using the WinLoad Utility
the Firmware Using NovAtel Application Suite
Updating the Firmware Using Setup & Monitor
on page 146 or
Updating Using SoftLoad Commands
Auth-codes work with any signed firmware image. Therefore, if a receiver has an auth-code for the old version
of firmware, that same auth-code will work for the new version of firmware, provided both images are digitally
signed by NovAtel.
Signed firmware images are distributed in *.shex files. The new download package includes a signed firmware
file type that uses an extension designated as “.shex” (example OM7MR0200RN0000.shex), as well as the
latest WinLoad utility and What’s New file containing firmware update change details.
Temporary auth-codes may be provided by NovAtel for evaluation purposes. Once the trial period has
expired, the functionality provided by the auth-code is removed. The expiration date for temporary auth-codes
is in the form YYMMDD, where YY = year, MM = month and DD =day. The date is the last day that the auth-
code is valid and expires at the end of day, UTC time.
Once the trial period has expired, a new auth-code will need to be obtained from NovAtel Customer Support
(
).
Firmware images may also have auth-codes embedded within them. The models provided by such firmware
images will be valid only on receivers with certain PSNs and Hardware Versions.
