Section 1. CFM100 CompactFlash

Module Overview

1-3

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.

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.

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.
