Firmware Updates
As described in
, the Signal Generator is comprised of two independent L1 and L5 generators. Each
digital card has the same firmware (program software). The firmware is stored in on-board, non-volatile memory,
which allows the Signal Generator's firmware to be updated in the field. Thus, updating firmware takes only a few
minutes instead of the several days which would be required if the Signal Generator had to be sent to a service
depot.
When updating to a higher revision level, you will need to transfer the new firmware to the appropriate card using
WinLoad, a Windows-based program. It is recommended that you use the most recent version of WinLoad
available.
Below is shown an outline of the procedure for updating your Signal Generator's firmware:
1. Contact the NovAtel Customer Support (refer to Contact Information on Page 8 for contact options)
2. Download update files
3. Decompress files
4. Run the firmware loading utility

After conferring with the NovAtel Customer Support to establish the required revision level, as well as the terms
and conditions of your firmware update, the NovAtel Customer Support will issue you with the latest firmware
when it is available.
If it is determined that you will be updating to a higher revision level with the use of the firmware loading utility,
the NovAtel Customer Support will confirm with you as to the procedures, files, and methods required for using
this utility. As the main utility and other necessary files are generally provided in a compressed file format, you will
also be given a file decompression password. The utility and update files are available from NovAtel Customer
Support.
