5. Additional Information on SMCRead Operation
5.1 Reading Data from More Than One Card
SMCRead automatically detects the removal of a card from the card slot and
will update the status window accordingly. SMCRead indicates the removal
and insertion of a card by generating a series of short beeps.
5.2 Aborting Options
Most SMCRead operations can be stopped by pressing the
ESC
key. You are
then returned to the options menu.
5.3 Battery Voltage Warnings
If when the program is run you get a warning in the module status window that
shows the card battery as being ‘DEAD!’, the battery in the card is close to
being, or is completely discharged.
Do not unplug the card from the PC or power down the PC
at this stage. Read any data that is present in the card
before removing power from the card.
It cannot be assumed that the card is powered just because it is in a slot.
Exercise caution when changing the battery and ensure that any data present in
the card is read first. The normal procedure for replacing the battery is
outlined below.
Read all data, remove the card, replace the battery and then rerun SMCRead
using the E option to reformat and test the card. When you first plug in a card
that has lost power SMCRead indicates that the card is unplugged or corrupted
and can show spurious numbers in the module status window. Continue past
the warning message and select the E option. After the card has been erased
and formatted the module status returns to normal.
If the battery status displays LOW you should change the battery as soon as
possible as it may have less than 3% of its original capacity. If the battery
status is ‘DEAD’ a CSM1 will not allow you to store data in the card from a
datalogger.
5.4 Card Errors
If SMCRead detects that the error counter in a memory card is reading 255, a
warning is displayed in the module status window indicating that the card has
been corrupted. This means that some of the reserved memory in the card has
been corrupted. As the reserved memory area is used to store the various
pointers to data in the card, the process of reading data out of the card may be
prone to errors.
