11. SETTINGS AND MEMORY CARD
The M3x5 is provided with a built in slot for a full size SD memory card (also MMC) that is
used for transfer of records from the internal memory, device settings download and
software upgrading. The memory card needs to be formatted with the FAT16 file system.
Directory structure on a memory card
A structure of directories is defined and enables correct data handling via a memory card.
The memory card shall contain the following directories and files:

DATA

SETTING

UPGRADE

File: Automenu.txt (option)
DATA
Records from the products internal memory are stored in the DATA directory. To upload data
from several devices to the memory card, each device checks and, if necessary, creates its
own subdirectory before data transfer. Each subdirectory uses the device serial number as
its name and stores files with data in it. Each file name contains date (year, month and day)
and a record sequence number of that day.
WARNING
When uploading data file to the memory card and there is a file with sequence number 99 of
that day, a file with sequence number 00 is generated. Files with identical sequence
numbers of that day, will be overwritten if any further data uploads are done that day.
Settings
Settings are stored in the directory using two recording modes:

With a type designation and a sequence number from 1 to 9

With an device serial number
Upgrade
A file with upgrades is available for upload with the QDSP2 software. The file has the name
of the corresponding device type designation and suffix FL2 (e.g. M355.FL2).
Automenu.txt
For faster and easier upgrading of the firmware there is the »Automenu.txt« file in the root
directory. When a memory card with this file is inserted and if the upgrade version is later
than that installed in the product the display automatically jumps into the memory card menu
and suggests the Software upgrade menu, otherwise it automatically jumps into the Save
data menu.
When upgrading is finished and the OK key is pressed and the memory card is removed, the
menu that was displayed before inserting the memory card is displayed.
Automenu.txt file can be created by the user by means of a text editor. A new file has to be
opened and saved under the correct name (Automenu.txt) and without content.
