Trimble R7 GPS Receiver Operation
An application file does not have to contain all of these records. When
you apply an application file, any option that is not included in the
records in the file remains at its current setting. For example, if you
apply an application file that only specifies the elevation mask to use,
all other settings remain as they were before the application file was
applied.
You can store up to twenty different application files in battery-backed
memory on the receiver. You can apply an application file’s settings at
the time it is transferred to the receiver, or at any time afterwards.
53.1 Special application files
The Trimble R7 receiver has three special application files, which
control important aspects of the receiver’s configuration.
Default application file
The default application file (Default.cfg) contains the original receiver
configuration, and cannot be changed. This file configures the receiver
after it is reset. To reset the receiver, hold down [P] for at least 15
seconds, or use the reset option in the GPS Configurator software.
For more information, see Default Settings, page 80.
Although you cannot change or delete the default application file, you
can use a power up application file to override any or all of the default
settings.
Current application file
The current application file (Current.cfg) reflects the current receiver
configuration. Whenever you change the receiver’s configuration,
either in real time or by applying an application file, the current file
changes to match the new configuration.
You cannot delete the current file or change it directly, but every
change to the receiver’s current configuration is applied to the current
file as well.
