Picture 46. The MMC module: 1–MMC slot; 2– Hold recording button ; 3–control diode lamp.
The MMC module of the maMoS monitor works properly with MMC / SD cards with a max-
imum capacity of 4 GB and a FAT-16 file system format. The files containing the current
measurement results shown on all the displays and analogue outputs are stored on the
card. The files are saved in the root directory of the card. A single file can consist of up to
10 000 results. If the amount is exceeded a new file will be created and the succeeding
results will be saved in it.
The file name is created according to the FAT-16 system in a 8+3 pattern (which
is: eight characters forming the name and three characters of the file's extension). The
files containing the measurements are given the mrp extension. The file name is the next
number from the device's internal counter (for example 00000012.mrp) which counts the
number of files created by the monitor.
Attention!
If one card is used in several devices the monitor might create a file
named the same as the one already existing on the card file. It will
be impossible to read such a file afterwards.
Such a situation can be avoided in a number of ways:
−
a separate MMC can be used for each of the devices;
−
the card can be formatted before it is inserted into the analyser's MMC slot
(the FAT-16 file system) – more informations can be found in chapter 5.4.2.
−
before the card is inserted into the slot a new subdirectory should be created
on the card. That is where the files from the previous measurements can be
moved. The new measurement results are saved only in the root directory of
the card.
