Syntax:
$AUTH auth-code
where
$AUTH is a special command that allows program model upgrades
auth-code is the upgrade authorization code, expressed as hhhh,hhhh,hhhh,hhhh,hhhh,model#
where the h characters are an ASCII hexadecimal code, and the model# would be ASCII text
Example:
$auth 17cb,29af,3d74,01ec,fd34,millenrt2
Once the $AUTH command has been executed, the MiLLennium-GLONASS GPSCard resets itself. Issuing the
VERSION command produces a response confirming the new upgrade model's type and version number.
5.1.2 UPDATING USING THE LOADER UTILITY
Loader is required when updating previously released firmware with a newer version of program and model
firmware (e.g., updating a MiLLennium-GLONASS GPSCard Standard rev. 7.46 to a higher revision level of the
same model). Loader is a DOS utility program designed to facilitate program and model updates. Once Loader is
installed and running, it will allow you to select a host PC serial port, bit rate, directory path, and file name of the
new program firmware to be transferred to the MiLLennium-GLONASS GPSCard.
5.1.2.1 Transferring Firmware Files
To proceed with your program update, you must first acquire the latest firmware revision. You will need a file with
a name such as OEMXYZ.EXE (where XYZ is the firmware revision level). This file is available from NovAtel's
FTP site (http\\www.novatel.ca), or via e-mail (support@novatel.ca). If transferring is not possible, the file can be
mailed to you on floppy disk. For more information on how to contact NovAtel Customer Service please see Page
7 at the beginning of this manual.
You will need at least 1 MB of available space on your hard drive. For convenience, you may wish to copy this file
to a GPS sub-directory.
Example:
C:\GPS\LOADER
The file is available in a compressed format with password protection; your local dealer will provide you with the
required password. After copying the file to your computer, it must be decompressed. The syntax for
decompression is as follows:
Syntax:
[filename] -s[password]
where
filename
-s
password
Example:
oem746 -s12345678
The self-extracting archive will then generate the following files:
• LOADER.EXE Loader utility program
• LOADER.TXT Instructions on how to use the Loader utility
• XYZ.BIN
GPS/GLONASS Receiver User Manual Rev 1
is the name of the compressed file (but not including the .EXE extension)
is the password command switch
is the password required to allow decompression
Firmware version update file, where XYZ = program version level (e.g. 746.BIN)
