NL116 Ethernet Interface and CompactFlash Module
Ethernet Connectivity and Expanded Data Storage
weather applications water applications energy applications gas flux & turbulence applications infrastructure applications soil applications


Ethernet connectivity and expanded data storage capacity are easily added to a CR1000 or CR3000 by attaching an NL116. The Ethernet connection provides access to the powerful Internet capabilities of the datalogger for data collection and control. Additionally, gigabytes of data and file storage capacity can be added to the datalogger using a removable CompactFlash card.

Benefits and Features

  • Provides a native Ethernet connection, allowing the datalogger to communicate directly using a variety of Internet protocols
  • CompactFlash cards can be used to greatly expand data storage capacity
  • The ability to remove and swap cards makes retrieving data and files fast and simple
  • Integrated protection for surge and ESD
  • Datalogger-controlled power-management schemes for low-power operation

Frequently Asked Questions

Number of FAQs related to NL116: 2

  1. The NL116 is the same as the NL121, with the addition of a CompactFlash card slot that can be used with a removable CompactFlash card to extend data storage and data collection.

  2. The maximum recommended segment length (length of cable between the NL device and the Ethernet repeater, hub, switch, or router it is connected to) for 10Base-T and 100Base-Tx networks using CAT5e cable is 100 m.
