Ethernet and CompactFlash Module - NL115
Campbell Scientific’s NL115 Ethernet/CompactFlash Module provides two
useful capabilities. It enables 10baseT Ethernet communications and stores
data on a removable CF-Card. So it is possible to communicate over the local
network of the BGC-FTIR-Container, respectively via TCP/IP.
To remove a card, press the control button on the NL115. The datalogger will
transfer any buffered data to the card and then power it off. The status LED
will turn green when it is OK to remove the card. The card will be reactivated
after 20 sec if it is not removed.

More important is the use of data transfer via FTP. The calibration factors
and constants which transform the signals into real units are stored on the
CF-Card. This makes it possible to modify them without a need to access the
main program on the CPU. For details see section 1.3.3 on page 39.
When you are connected through a ethernet line you can also visit the home-
page of the datalogger to check the latest records or the status.

NOTE: Removing a card while it is active can cause grabled data and can
actually damage it. Do not switch off the datalogger power if a card
is present and active.
