Campbell Scientific NL115 Ethernet Interface and CompactFlash Module - Manual (Page 7)

NL115 Ethernet and CompactFlash ®
Module
1. Introduction
Campbell Scientific’s NL115 Ethernet/CompactFlash ® Module provides two
independent capabilities: (1) it enables 10Base-T Ethernet communications
and (2) stores data on a removable CompactFlash (CF) card. It allows the
datalogger to communicate over a local network or a dedicated Internet
connection via TCP/IP. It also expands on-site data storage and provides the
user with a convenient method of transporting data from the field back to the
office. This small, rugged communication device connects to the 40-pin
peripheral port on a CR1000 or CR3000 datalogger.
This manual describes how to use LoggerNet to connect to your datalogger
with an NL115 attached. You can also use other software packages such as
PC400, RTDAQ, or LoggerLink Mobile Apps for iOS and Android.
Campbell Scientific recommends that only FMJ CF cards be used with the
NL115. For more information on CF cards, see Campbell Scientific’s
application note CF Card Information (3SM-F). Note that it is not necessary to
purchase the FMJ CF cards directly from Campbell Scientific as long as the
FMJ model number matches those shown in the application note.
Before using the NL115, please study:
• Section 2, Cautionary Statements
• Section 3, Initial Inspection
• Section 4. Quickstart
The Quickstart section explains how to quickly begin using an NL115 for
straightforward Ethernet communications and data-storage operations. The
remainder of the manual is a technical reference which describes in detail such
operations as: TCP/IP functionality, file formats, datalogger programming, and
data retrieval.
2. Cautionary Statements
• The NL115 is rugged, but it should be handled as a precision scientific
instrument.
• 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
NL115 from the datalogger.
• The first time an NL115 is attached to a datalogger, the datalogger’s
memory has to be reorganized to allow room in memory for the IP stack.
To avoid the loss of data, collect your data before attaching the NL115 to a
datalogger.
