Data Logging

Providing that you have registered your PerformanceBox (see Quick Start Guide) then it will be

capable of logging data to an SD card.

Using the SD card

The Performance Box will only work with SD and SDHC hardware.

Files logged by PerformanceBox are named ‘PBOX_001.dbn’, where 001 increments when a new

file is created. A new file is created every time PerformanceBox is powered up, or when the card is

re-inserted. If you wish to log data to the SD card then simply insert the card into the slot in the

front of PerformanceBox. PerformanceBox will log vehicle position, speed and acceleration into a

binary ‘.dbn’ file which can be opened in PerformanceTools software for analysis. This data is

logged when velocity is above 0.5Km/h.

The PerformanceBox has two logging modes, selectable through the SETUP menu available from

any screen.

 ONLY WHEN MOVING: In this mode GPS and PerformanceBox data is only logged to an

SD card (.DBN file) whilst the Speed is greater than 0.5km/h.

Only ever remove the SD card when you are stationary, otherwise you will risk losing

data or corrupting the card (which would require a re-format).

 CONTINUOUS: In this mode all GPS and PerformanceBox data is logged to the SD card

(.DBN file) regardless of Speed or satellite reception.

Before removing the SD card, the data-logging process must be stopped by pressing

the MENU button, which ends the writing of data to the card and closes the current

file.

To read data from the card either insert the card into a SD card reader connected to your computer

or connect your computer directly to PerformanceBox via the supplied USB cable to read the data

from the card. PerformanceBox must not be writing to the card when you connect to your PC, so

you must be stationary. To ensure Windows recognises a PerformanceBox, power up your

PerformanceBox before connecting the USB cable to your PC.
