Data Transfer
Received data is stored temporarily in a buffer (1024 bytes). The SpaceLogger inserts the time
and date at the start of each data record. Data is transferred from the buffer to the SD card in 512
byte packages.
If no data has been received from the data source(s) for a set time period (a time equal to twice the
selected logging rate plus 12 seconds), any remaining data in the buffer is written to the SD card.
The red LED blinks each time data is written to the card.
The SD card should not be removed while data is being written to it. To stop recording data, the
small button to the left of the card slot on the front of the SpaceLogger should be depressed.
There will be an audio signal to indicate that the button has been pressed. This action will also
purge any data in the buffer to the SD card so the card is ready to be removed from the
SpaceLogger. The green LED will automatically switch off to indicate that the unit is no longer
enabled to record further data.
To recommence data logging the power must be cycled or a card re-inserted in order to re-
initialise the card. The green LED will again indicate the unit as ‘Ready to Record Data’.
To avoid losing data or corrupting the card, never remove the card or disconnect the power supply
when the red LED is flashing or blinking.
When the memory card becomes full the SpaceLogger will stop logging data; it will not overwrite
files already saved.
