Logging Data
You can log data internally or to a Trimble controller.
145.1
Logging internally
The Trimble R8 receiver logs GPS data internally on 6 MB of internal
memory.
You can then use the Trimble Data Transfer utility to transfer logged
data files to the office computer. The transferred files are in Trimble
DAT (.dat) format.
C
WARNING – The Trimble R8 allows for a maximum of 200 files on the
internal memory. The filenames must be in 8.3 format, otherwise files
copied to the internal memory may cause data corruption or loss of data
when logging.
Data is logged using the current logging settings configured in the
receiver. Data files logged internally are named automatically.
To begin internal logging, you must use a Trimble controller, or the
GPS Configurator utility. The Trimble R8 receiver does not have an
internal clock, so you can only conduct timed survey sessions if the
receiver has a continuous power supply.
When the internal memory is full, the receiver stops logging data, and
the Logging/Memory LED switches off. Existing data files are not
overwritten. You can use the Auto-delete option to override this action
and automatically delete the oldest files when the receiver memory is
full. However, you should use this option with caution because it can
lead to data loss.
