Overview
(Press card button prior to flipping the power switch). If the logger is powered
off using software control (PowerOff instruction), the data buffered in the CPU
is flushed to the card and the Logger is shut down properly.
DO NOT POWER DOWN LOGGER WHILE PCMCIA CARD
IS ACTIVE. NOTE
LED code description:
Dark: No card detected or formatted card present without errors
Yellow: Either no card or corrupt card with program trying to access the card
Red:
Accessing the card
Green: Can safely remove the card
Only Industrial grade PC cards should be used. They can operate over a wider
temperature range, have better vibration and shock resistance, have faster
read/write times, and can withstand more write cycles than the commercial
grade cards. It should be remembered that a system is only as good as its
weakest link. Do not buy a cheap memory card to store data for a test whose
results are important.
See Appendix C PC/CF Card Information for details on selecting memory card.
Up to a total of 30 data tables, each capable of storing data at different rates,
can be created between the CPU's SDRAM and the PC Card. Data Tables
created on the PC cards will also have a buffer table created in SDRAM. The
size of this buffer can either be manually or auto allocated.
