Note: The NL115 has been replaced by the NL116 but remains available for order until our existing inventory is depleted. Because the NL116 requires a CR1000 or CR3000 to use datalogger operating system version 28 or greater, users who do not wish to update their dataloggers at this time may choose to purchase the NL115.--> Campbell Scientific’s NL115 enables 10baseT Ethernet communications and stores data on a removable CompactFlash® card. This small, rugged communication device connects to the 40-pin peripheral port on a CR1000 or CR3000 datalogger.
