Logging data
You can log data internally or to a Spectra Precision Recon
®
controller.
33.1
Logging internally
The Epoch 25 GPS receiver logs GPS data internally on 2 MB of internal memory. You
can use the Spectra Precision Data Transfer
utility to transfer logged data files to the
office computer. The transferred files are in TO1 format.
C
WARNING – The Epoch 25 GPS receiver allows for a maximum of 512 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.
You must use a Spectra Precision Recon controller to begin internal logging, . The
Epoch 25 GPS receiver does not have an internal clock, so you cannot conduct timed
sessions.
Note –
When the internal memory is full, the receiver stops logging data, and the
Logging/Memory LED switches off. Existing data files are not overwritten.
