1. Introduction
Campbell Scientific’s CFM100 CompactFlash
®
Module stores the datalogger’s
data on a removable CompactFlash (CF) card. The CFM100 module connects
to the datalogger via the 40-pin peripheral port. Currently, only the CR1000
and CR3000 dataloggers have the 40-pin peripheral port; the CFM100 is not
compatible with the CR200-series, CR800-series, CR6-series, CR300-series,
CR5000, and CR9000X dataloggers.
Before using the CFM100, please study:
•
Section 2 , Precautions
(p. 1)
•
Section 3 , Initial Inspection
(p. 2)
•
Section 4 , QuickStart
(p. 2)
The QuickStart explains how to quickly begin using a CFM100 for
straightforward data-storage operations. The remainder of the manual is a
technical reference which describes in detail such operations as file formats,
datalogger programming, and data retrieval.
2. Precautions
•
READ AND UNDERSTAND the Safety section at the front of this
manual.
•
The CFM100 is rugged, but it should be handled as a precision scientific
instrument. There are no user-serviceable parts inside the module.
•
The 28033 surge suppressor and/or a shielded 10base-t Ethernet cable
should be used for locations susceptible to power surges and for cable
lengths longer than 9 ft.
•
Always power down the datalogger before installing to or removing the
CFM100 from the datalogger.
•
Removing a CompactFlash 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.
•
For a card formatted as FAT16, the maximum number of files that can be
stored is 512. To reach that maximum you must keep filenames to 16
characters plus 3 characters for the extension. FAT32 formatted cards do
not have the same limitation, and the number of files that can be stored is
limited by the amount of space on the card.
