Trimble R7 GPS Receiver Operation
Note – If power is lost, or the CompactFlash card is removed while logging,
the file system is designed so that a maximum of ten seconds of data will
be lost, regardless of the logging rate. To ensure that this behavior occurs,
use GPS Configurator to perform a quick format of the CompactFlash card
before logging data to the card for the first time.
44.2 Logging to a Trimble controller
When the Trimble R7 receiver is connected to a Trimble controller, you
can log GPS data from the receiver to the controller, or to a PC card
inserted in the controller. When you use a Trimble controller, you do
not use the receiver’s controls. Instead, you use the controller functions
to set logging options, specify filenames, and to control when logging
occurs.
Data is stored in job files, which can be transferred to your office
computer using Trimble’s Data Transfer utility.
For more information on logging data from a receiver using a Trimble
controller refer, to the user guide for your particular controller.
4.5 Resetting to Defaults
C
WARNING – Do not hold down [P] for more than 30 seconds. After 30
seconds, any application files stored in the receiver are deleted and the
CompactFlash card is reformatted.
To reset the receiver to its factory default settings, hold down [P] for at
least 15 seconds.
Resetting the receiver to its factory defaults also deletes any ephemeris
file in the receiver.
For more information, see Chapter 9, Default Settings.
