NL116 Ethernet and CompactFlash ® Module
5.1 Buttons and Status LED
There is one red-green-orange LED (light-emitting diode) and two buttons:
Initiate Removal
and eject. The
Status
LED indicates the status of the
module. The LED will flash red when the CF card is being accessed, solid
green when it is OK to remove the card, solid orange to indicate an error, and
flashing orange if the card has been removed and has been out long enough that
CPU memory has wrapped and data is being overwritten without being stored
to the card. The Initiate Removal button must be pressed before removing a
card to allow the datalogger to store any buffered data to the card and then
power off. The eject button is used to eject the CF card. Note that if the eject
button cannot be pressed, it may have been disabled by bending it to the right.
Straighten and press the eject button to eject the CF card.
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 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.
