Campbell Scientific NL115 Ethernet Interface and CompactFlash Module - Manual (Page 13)

NL115 Ethernet and CompactFlash ® Module
5.2 Power
The Ethernet/CompactFlash module is powered by 12 Vdc received from the
datalogger through the peripheral port.
Additional power consumption occurs if the Status LED is continuously lit. At
12 Vdc, an additional 1 mA is drawn by the red or green LED; an additional
2 mA is drawn by the orange LED.
5.3 CF Card Data Retention
The module accepts CompactFlash (CF) cards which do not require power to
retain data.
Typically, a CF card can be erased and rewritten a minimum of 100,000 times.
Industrial CF cards, graded for 2,000,000 write cycles, are recommended for
most applications.
6. Specifications
Datalogger Compatibility: CR1000, CR3000
Storage Capacity: Depends on card size (up to 16 GB
supported; to use card size greater than 2
GB, the datalogger operating system must
be OS 25 or greater)
Power Requirements: 12 V supplied through datalogger’s
peripheral port
Current Drain: 19 mA (CR1000 with NL115 attached, no
Ethernet cable attached, not actively
communicating over Ethernet nor
accessing the CF card)
20 mA (CR1000 with NL115, Ethernet
cable attached)
20 mA (CR1000 with NL115
communicating over Ethernet)
43 mA (CR1000 with NL115
communicating over Ethernet and
accessing CF card)
2 mA (Ethernet port has been put to sleep
using the IPNET Power() CRBasic
instruction)
Add 1 mA to current drain if red or green
Status LED is continuously on.
Add 2 mA to current drain if orange Status
LED is continuously on.
Operating Temperature Range: –25° to +50°C Standard
–40° to +85°C Extended
