Downloading the Files
Typically, there are three files required when performing firmware updates on a particular Signal Generator card:
• WINLOAD.EXE (the firmware loading utility program)
• [Application Firmware File Name].HEX (the Application firmware update file)
• [FPGA Firmware File Name].HEX (the FPGA firmware update file)
For example, the Signal Generator Application and FPGA firmware files might be named SIGGEN-2.10.HEX and
SIGGEN-FPGA-2.9.HEX respectively.
To proceed with your update, you will first need to download the appropriate files. Contact NovAtel Customer
Support:
The files are available in compressed, password-protected file format. The compressed form of the files may have
different names than the names discussed above; NovAtel Customer Support will advise you as to the exact names
of the files you need. As well, NovAtel Customer Support will provide you with a file de-compression password.

Decompressing the Files
After copying the compressed files to an appropriate directory on your computer, each file must be decompressed.
A Windows-based dialog is provided for password entry.
The self-extracting archive then generates the following files:
WinLoad.exe
WinLoad utility program
HowTo.txt
Instructions on how to use the WinLoad utility
WhatsNew.txt

Running WinLoad
WinLoad is a Windows based program used to download firmware to Signal Generator cards. The main screen is
shown in
. Note that in order to load firmware on to the WAAS GUS Signal Generator, the following
hardware setup is required:
• Data Source Modules need to be connected to the L1 and L5 CMP ports and Code 1PPS Out ports. These
also have to be connected to the PC which will perform the firmware load, or at a minimum need to be
powered.
• The L1 and L5 WMP ports need to be connected to the PC which will perform the firmware load.
• A 1PPS signal needs to be provided into the 1PPS In port of the WAAS GUS Signal Generator.
Once these are in place, WinLoad can then be used to load firmware as described in the following sections.
