2.1 SD MEMORY CARD

The BS-1500 allows you to insert a micro-SD memory card. If this card is in-

stalled the module will also transfer all incoming data to the SD-card. For each

sensor and each month the system will generate data les containing measu-

rement data in plain-text format (csv).

The SD card data will only be accessible for reading and

further processing with an SD card reader. Further proces-

sing of data may be performed by external software tools

such as Excel and Word.

Initially the SD card must be formatted. Often cards which already have been

formatted are delivered, but if needed you can also format a card by PC-soft-

ware. In using SD-cards for the BS-1500 it is important to create a directory

‘log’ at the SD-card (if no such directory already exists) as a location to store

the logging les.

At the log-directory the system will generate a text le for each sensor and

each month.

The naming convention for the log-les is:

m<id><year><month>.txt

in which

id: the id-number of the sensor in hexadecimal format

(4/8 bytes).

year: the year in 4 decimals

month: the month in 2 decimals

All data which refers to the le-name’s criteria will be added to the relevant

data-le. A data le starts with a le header, followed by individual lines for

each data-record for one measurement data set.

<time-stamp>, <value>

in which

time-stamp: yyyy-mm-dd hh:mm:ss (UTC)

value: measurement data value in oating point format.

Latitude (degrees)

Longitude(degrees)

Altitude(meters)

Delivered from an SD-card these data sets can also be imported to a PC and

processed with e.g. Excel-software. The SD-cards’ data however also can

be imported to the logger software. Import from the SD-cards to the log-

ger software can be controlled by the import function – see menu:

le --> import.
