Notes on the usage of the data card drive:
•
All data cards are not created equal and some vary greatly in how well they adhere to
the specifications. Because of this, we recommend that a card from SanDisk with a
capacity of between 64 MB and 2 GB be used. Other manufacturer may also be used
but should be tested to verify that they save data correctly before depending on them
for routine use. Smaller and larger cards may not function correctly with the data
drive and could result in data loss. It is also recommend that a SD card with a write
protection switch be selected.
•
While it possible to save data to a card used for other purpose (i.e. like a digital
camera or portable drive), this is not recommended.
•
Each unit records a single data file that is named with the serial number of the unit. It
is therefore possible to use a single data card to save data from multiple units.
•
If a data card already contains saved data from the same unit, it will be overwritten.
•
If you experience errors when saving the data, it is possible that the data card is not
compatible or has become corrupted. Data cards can become corrupted if they are
used for purposes other than saving data from the unit or if the data saving process is
interrupted. In most cases, this can be resolved by formatting the card on a PC.
Erasing Data

The ERASE menu (shown above) provides ability to erase the different data logs that are
collected by the system. The control unit automatically overwrites the oldest data in each of
the logs, so this feature does not need to be used on a routine basis. It can be used in
situation where the unit has changed locations and the user no longer wishes to review the
data from the other site.
