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.

Detailed Description

Data Storage on CompactFlash Cards

One Type I or Type II (CF) card fits into the NL116’s card slot. Campbell Scientific offers and recommends the CFMC256M, CFMC2G, and CFMC16G CF cards (see Ordering Information). Only industrial-grade CF cards should be used with our products. Although consumer-grade cards cost less than industrial-grade cards, the consumer-grade cards are more susceptible to failure, resulting in both the loss of the card and its stored data. Industrial-grade cards also function over wider temperature ranges and have longer life spans than consumer-grade cards.

The NL116/CF card combination can be used to expand the data logger’s memory, transport data/programs from the field site(s) to the office, and upload power up functions. The computer can read the CF card with the computer’s USB port and the 17752 Reader/Writer.
