and exchanged for the one which is
retrieved so that data collection can
continue uninterrupted.
2. Bring a storage device to the datalogger
and transfer all the data that has
accumulated in Final Storage since the last
visit.
3. Retrieve the data over some form of
telecommunications link, that is, Radio
Frequency (RF), telephone, short haul
modem, multi-drop interface, or satellite.
The PC208 TELCOM program automates
this process for IBM PC/XT/AT/PS-2's and
compatibles.
Regardless of which method is used, the
retrieval of data from the datalogger does NOT
erase those data from Final Storage. The data
remain in the ring memory until:
- they are written over by new data (Section
2.1)
- memory is reallocated (Section 1.5)
- the power to the datalogger is turned off.
Table OV5-1 lists the instructions used with the
various methods of data retrieval.
