CFM100 CompactFlash ® Module
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. CAUTION
4.3 Data Retrieval
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
control button and wait for a green light before removing
card. CAUTION
LoggerNet’s 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. CAUTION
5. Overview
The CFM100 connects to a datalogger’s peripheral port and has a slot for a
Type I or Type II CompactFlash (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.
LoggerNet’s 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. CAUTION
