NL120 Ethernet Module
1. Introduction
Campbell Scientific’s NL120 Ethernet Module enables 10Base-T Ethernet
communications. It allows the datalogger to communicate over a local network
or a dedicated Internet connection via TCP/IP. 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 NL120 attached. You can also use other software packages such as
PC400, RTDAQ, or LoggerLink Mobile Apps for iOS and Android.
Before using the NL120, please study:
• Section 2, Cautionary Statements
• Section 3, Initial Inspection
• Section 4, Quickstart
The Quickstart section explains how to quickly begin using an NL120 for
straightforward Ethernet communications. Section 6 describes in detail the
TCP/IP functionality of the NL120.
2. Cautionary Statements
• The NL120 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
length longer than 9 ft.
• Always power down the datalogger before installing or removing the
NL120 to or from the datalogger.
• The first time an NL120 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 NL120 to a
datalogger.
3. Initial Inspection
Upon receipt of the NL120, inspect the packaging and contents for damage.
File damage claims with the shipping company.
