3.5 Logging Data
You can log data to the CompactFlash card in the 5700 receiver, or
alternatively to the survey device.
3.5.1 Logging Internally
The 5700 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.
Data is logged using the current logging settings configured in the
receiver. Data files logged internally are named automatically.
To begin internal logging, press . The Logging/Memory LED
lights up.
To stop logging, hold down  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 3.2. The values shown are for a one-hour logging
session with six satellites visible.
