Overview

0 for ring mode. This means that once the data table is full, new data will begin
overwriting old data. The size parameter is –1, so all available space on the
card will be allocated to the table.

To prevent losing data, collect data from the CF card before
sending the datalogger a new or modified program. When a
program is sent to the datalogger using the Send button in
the Connect screen of LoggerNet or PC400, an attribute is
sent along with the program that commands the datalogger
to erase all data on the CF card from the currently running
program.
Data stored on cards can be retrieved through a communication link to the
datalogger or by removing the card and carrying it to a computer with a CF
adapter. With large files, transferring the CF card to a computer may be faster
than collecting the data over a communication link. Data retrieval is discussed
in detail in Section 7.3, Data Retrieval
Removing a card while it is active can cause garbled data
and can actually damage the card. Always press the
Initiate Removal button and wait for a green light before
removing card.
LoggerNet File Control should not be used to retrieve data
from a CompactFlash card. Using File Control to retrieve the
data can result in a corrupted data file.
The CFM100 connects to a datalogger's peripheral port and has a slot for a
Type I or Type II CF card (3.3 V, 75 mA). The CFM100/CF card combination
can be used to expand the datalogger's memory, transport data/programs from
the field site(s) to the office, upload datalogger power-up functions, and store
JPEG images from the CC640 camera. Data stored on cards can be retrieved
through a communication link to the datalogger or by removing the card and
carrying it to a computer. The computer can read the CF card either with the
CF1 adapter or 17752 Reader/Writer. The CF1 adapter allows the PC's
PCMCIA card slot to read the CF card; the 17752 Reader/Writer allows the
PC's USB port to read the CF card. User-supplied CF adapters may also be
used.
