Module Overview
1.3 Power
1.3.1 Primary Power
The Ethernet/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 NL115 Ethernet/CompactFlash Module enables 10 Base T Ethernet
communication with the datalogger.
The NL115/CF card combination can be used to expand the datalogger’s
memory, transport data/programs from the field site(s) to the office, upload
power up functions, and store JPEG images from the CC640 camera. Data
stored on cards can be retrieved through a communications 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 communicating via Ethernet and storing
and retrieving datalogger data. These operations are discussed in detail in
Sections 2, 4, and 5 of this manual.
1.5.1 Physical Set-up
Always power down the datalogger before installing or
removing the NL115 to/from the datalogger.
CAUTION
After powering down the datalogger, plug the NL115 into the datalogger
peripheral port. Attach Ethernet cable to the 10 Base T port. Restore power to
the datalogger. Insert formatted CF card. (For instructions on formatting a CF
card, see Appendix A.)
A CF card does not need to be present in order to use the
NL115’s TCP/IP functionality.
