Logging Data
You can log data to the CompactFlash card in the receiver, or to the
survey device.

Logging internally
The Trimble R7 receiver logs GPS data internally on a CompactFlash
card. You can then use the Trimble Data Transfer utility to transfer
logged data files to your office computer. The transferred files are in
Trimble DAT (.dat) format.
C
WARNING – The Trimble R7 allows for a maximum of 512 files on the
CompactFlash card, regardless of the card’s capacity. The file names
must be in 8.3 format, otherwise files copied to the CompactFlash card
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, press d. The Logging/Memory LED lights
up.
To stop logging, hold down d for at least two seconds. The
Logging/Memory LED turns off.
Note – When the CompactFlash card is full, the receiver stops logging
data, and the Logging/Memory LED switches off. Existing data files
are not overwritten.
Approximate storage requirements for different logging rates are
shown in Table 4.2. The values shown are for a one-hour logging
session with six satellites visible.
