Configuration 5
Trimble R7 GPS Receiver Operation
• Timed Activation
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 GPS 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 60.
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.
When you turn off the receiver then turn it on again, all the settings from the current
application file are applied, so you do not lose any changes that you have made. The
only exceptions are the following logging parameters:
• Logging rate
• Position rate
• Elevation mask
These parameters are always reset to the factory default values whenever the receiver
is switched off.
