Chapter 8 NovAtel Firmware and SoftwareOEM7 Installation and Operation User Manual v1 109monitored in the SOFTLOADSTATUS log. Any status enum value greater than the ERROR statusindicates an error has occurred during the SoftLoad update. In the event of an error, theSoftLoad update should be restarted by issuing a SOFTLOADRESET command or normal oper-ation can be restored by resetting the receiver.In rare cases after a SoftLoad error, the boot code may not be able to determine which is thelatest firmware to be executed. To protect against this, SoftLoad does not erase the previousvalid firmware image from flash on the receiver. In such cases, the boot code will execute theold image and raise the "Safe Mode" error (see RXSTATUS log). If that error is detected, simplyrestart the SoftLoad process to reload the new firmware image and the error will be resolved.8.5 Upgrading Using the AUTH CommandThe AUTH command is used to upgrade to a new OEM7 family model with an authorization codethat enables (unlocks) model features. This command only functions with a valid auth-codeassigned by NovAtel Customer Support.The upgrade can be performed directly through the NovAtel Connect command line or from anyother communications program.Refer to Format of Firmware Files on page 101 for details on updating versusupgrading.8.5.1 Upgrade Procedure1.

Issue the LOG VERSION command to verify the current model, firmware version and serialnumber (refer to Authorization Code on page 100 for instructions on obtaining).3. Issue the AUTH command, followed by the auth-code and model type (refer to AuthorizationCode on page 100 for details on obtaining any auth-code). The syntax is as follows:auth auth-code here>where auth is a command that enables model upgrades and auth-code is the upgrade author-ization code, expressed as follows:XXXXXX,XXXXXX,XXXXXX,XXXXXX,XXXXXX,MODEL,EXPDATEwhere:l Each X character is a case-insensitive ASCII character.l The MODEL string is a maximum of 15 characters long and represents the modelenabled by the auth-code.l The EXPDATE string is the auth-code’s expiry date, in YYMMDD formatExample:auth 7WBMBK,887CB6,K5J3FH,5DF5P2,42PW8G,D1SB0GTT0,121211When the AUTH command is executed, the OEM7 family receiver reboots.
