Trimble R7 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.
45.2 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 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.
4.6 Resetting to Defaults
To reset the receiver to its factory default settings, hold down p for at
least 15 seconds.
C
WARNING – Make sure that you 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.
