Novatel 01018518 User Manual

The receiver stores its program firmware in non-volatile memory, which allows you to perform 
firmware upgrades without having to return the receiver to the distributor. New firmware can be 
transferred to the receiver through COM1, and the unit will immediately be ready for operation at a 
higher level of performance.

The first step in upgrading your receiver is to contact your local NovAtel dealer. Your dealer will 
assist you in selecting the best upgrade option that suits your specific GPS needs. If your needs are 
still unresolved after seeing your dealer then you can contact NovAtel directly through any of the 
methods described in the Customer Service section, page 15, at the beginning of this manual.

When you call, have your receiver model number, serial number, and program revision level 
available. This information can be found by issuing the LOG VERSION command at the port prompt.

After establishing which new model/revision level would best suit your needs, and having described 
the terms and conditions, you will be issued an authorization code (auth-code). The auth-code is 
required to unlock the new features according to your authorized upgrade model type.

To upgrade to a higher performance model at the same firmware revision level, you can use the 
AUTH command with the issued auth-code.

If you are upgrading to a higher firmware revision level, you will need to transfer new program 
firmware to the OEMV family receiver using the WinLoad utility program. As WinLoad and the 
upgrade file are generally provided in a compressed file format, you will also be given a 
decompression password. WinLoad and the upgrade files can be found on NovAtel's FTP site at 

http:/

/www.novatel.com

, or can be sent to you by e-mail.

Your local NovAtel dealer will provide you with all the information that you require to upgrade your 
receiver.

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. 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 in the OEMV Family Installation and Operation User Manual).

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:
