Section 1. CFM100 CompactFlash
®
Module Overview
1.3 Power
1.3.1 Primary Power
The CompactFlash Module is powered by 12 VDC received from the
datalogger through the peripheral port.
1.3.2 Backup Power and Data Retention
The module accepts CompactFlash (CF) cards which do not require power to
retain data.
Typically, a CF card can be erased and rewritten a minimum of 100,000 times.
Industrial CF cards, graded for 2,000,000 write cycles, are recommended for
most applications.
1.4 Function
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
1.5 Quick Start Procedure
This Section describes the basics of storing and retrieving datalogger data.
These operations are discussed in detail in Sections 3 and 4 of this manual
.
1.5.1 Preparation
Always power down the datalogger before installing or
removing the CFM100 to/from the datalogger.
CAUTION
After powering down the datalogger, plug the CFM100 into the datalogger
peripheral port. Restore power to the datalogger. Insert formatted CF card.
(For instructions on formatting a CF card, see Appendix A.)
1.5.2 Programming the Datalogger to Send Data to the CFM100
The CardOut instruction is used in the datalogger program to send data to the
CF card. The CardOut instruction must be entered within each DataTable
declaration that is to store data to the CF card. The file is saved to the card
with the name stationname.tablename and a .DAT extension.
