SD Card Functions
The petMAP+II contains an SD card slot which can be used to automatically record all vital signs data on
a user supplied SD card for archiving directly to the SD card and for optionally transferring to a PC/MAC
for long term storage, display and/or printing. The SD card can also optionally record an image of the
screen at any time by pressing the “Save Screen” button and/or by responding to the prompt at the time
the unit is switched OFF by the user.
To use these SD card storage functions a 2, 4, 8 or 16 GB SD card must be properly inserted into the SD
card slot. The card must be inserted with the card label facing up when the unit is being viewed normally
and pressed firmly into the slot such that it is entirely within the slot and no portion is protruding from
the side of the petMAP+II device. To remove the card, press it firmly further into the slot and then
release pressure and the card will eject automatically. The mechanical function of the SD card in the
petMAP+II is the same as in cameras that use SD cards for picture storage and will be familiar to most
users.
It is important to note if using a 2 GB SD card, it can only accommodate 512 files on a card or errors will
occur. For a 4 GB card, only 1024 files can be written on it or the same errors will be created. Should this
happen, the SD card must be removed and some number of data or image files erased or a new SD card
used in its place. If there is difficulty after changing the SD card, it is possible that the petMAP+II must
be hard powered OFF (by holding the ON/OFF button down for 10 seconds, followed by a new power
ON button press) or the unit will not function. For 8 and 16 GB cards, there are many more files
available, but writing time will be longer than with the smaller SD card sizes, particularly when using a
16 GB card.
Checking the available files on the SD card is easily done at the same time as when copying data from
the SD card to a PC/MAC. For many users, this restriction on the number of files with a 2 or 4 GB card
will not be a problem if the SD card is replaced every year. However, if the device is used in an active
clinic or very active OR setting and 2 monitoring sessions are done each week day and the screen image
is saved each time… in a year of use, there would be too many files for even the 4 GB SD card to hold the
data, ie: 260 days X 2 sessions/day X 2 files/session = 1040 files, and thus this number would slightly
exceed the 1024 allowable file count on a 4 GB SD card.
During petMAP+II use, the data for each measurement or monitoring session is automatically captured
in a .TXT file (described later in this manual) if there is an SD card in the unit. The screen image file
capture (described below) is enabled by the user either by pressing the “Save Screen” button or at
power OFF time. Not capturing the screen image allows a single SD card to last longer before needing
replacement, but the potential usefulness of the recorded screen image will be lost. It is suggested that
if recording is important to the user’s practice that SD cards be checked often and the data archived on a
PC/MAC before files are erased on the SD card to create more room on the card.
