6.5.1 Upgrading Using the AUTH Command
The AUTH command is a special input command which authorizes the enabling or unlocking of the
various model features. Use this command when upgrading to a higher performance OEMV family
model available within the same revision level as your current model (for example, upgrading from an
OEMV-3-L1 to an OEMV-3-RT2 on firmware version 3.000). This command only functions in
conjunction with a valid auth-code assigned by Customer Service.
The upgrade can be performed directly from CDU's Command Line Screen, or from any other
communications program. The procedure is as follows:
1) Power-up the OEMV family receiver and establish communications over a serial port (see
Chapter 4, Operation on Page 56)
2) Issue the LOG VERSION command to verify the current firmware model number, revision level,
and serial number.
3) Issue the AUTH command, followed by the auth-code and model type. The syntax is as follows:
Syntax:
auth auth-code
where auth is a special command which 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,l1l2lrvrt2
Once the AUTH command has been executed, the OEMV family receiver will reboot itself. Issuing
the LOG VERSION command will confirm the new upgrade model type and version number.
If communicating using CDU, the communication path needs to be closed and re-opened using the
Device menu.
6.5.2 Updating Using the WinLoad Utility
WinLoad is required (instead of the AUTH command) when upgrading previously released firmware
with a newer version of program and model firmware (for example, upgrading an OEMV-3-RT2
firmware version 3.000 to OEMV-3-RT2 firmware version 3.100). WinLoad is a Windows utility
program designed to facilitate program and model upgrades. Once WinLoad 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 OEMV family receiver via its COM1, COM2 or COM3
port. The port chosen must have an RS-232 interface to the PC.
Transferring Firmware Files
To proceed with your program upgrade, you must first acquire the latest firmware revision. You will
need a file with a name such as OEMXXXX.EXE (where XXXX is the firmware revision level). This
file is available from NovAtel's FTP site (http://www.novatel.com
), or via e-mail
([e-mail]). If transferring is not possible, the file can be mailed to you on floppy disk. For
