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 data logger for data collection and control. Additionally, gigabytes of data and file storage capacity can be added to the data logger using a removable CompactFlash card.
