Module Overview
Campbell Scientific's NL115 Ethernet/CompactFlash
®
Module provides two independent
capabilities: (1) enables 10baseT Ethernet communications and (2) stores data on a
removable CompactFlash 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 section of the manual surveys the NL115 and its functions. It also 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.
