Trimble R8 GPS Receiver Operation
When you switch 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.
Power Up application file
The power up application file (Power_up.cfg) is used to set the receiver
to a specific configuration any time the unit is powered up.
You can specify that the receiver is reset to defaults before the power up
settings are applied. This ensures that restarting the receiver always
resets it to factory defaults prior to applying the power up application
file.
Alternatively, you can specify that the power up settings are applied
immediately after the current application file’s settings have been
applied. Restarting the receiver results in a configuration that uses your
default settings for the options you define in the power up file, but the
current settings for all other options.
By default, there is no power_up application file on the receiver. To use
a power up application file, you must create and save a power_up
application file in the GPS Configurator software. If you save this file to
disk, the file is called power_up.cfg. The extension .cfg is used by
convention to identify application files on the office computer. When
you transfer this file to the receiver, the file is saved on the receiver as
power_up, and becomes the new power up file.
The power up file is the only special application file that you can
overwrite or delete from the receiver.
