Memory Cards
The VBOX III can accept Type-I compact flash memory cards. The memory cards must be formatted using FAT or FAT16 but not FAT32. This option is
normally selectable when formatting the memory card in a card reader connected to a PC.
When logging data to compact flash the blue CF LED will flash or be constantly illuminated. It is important not to remove the flash card while the blue LED is
illuminated. If the card is removed while the VBOX is writing data to it, there is a risk that the data file may be corrupted resulting in loss of data. To remove
the compact flash card while the VBOX is writing data, press the LOG button on the front panel of the VBOX and wait for the blue LED to turn OFF.
When a compact Flash card is inserted or removed while powered, the VBOX will re-initialise. This will reset any temporary parameters held in the VBOX. For
example, the CAN Bus parameter
Distance from power-on
will be reset to zero.
Note: The VBOXIII can log upto 32 CAN channels in addition to the standard GPS channels. This is limited to 16 CAN channels when the Kalman
Filter is enabled
GPS Antenna
The GPS Antenna supplied with the VBOX III is a 5v active antenna. For the best possible signal quality, it is important to maintain a clean connection
between the antenna and the VBOX. Before fixing the antenna to the VBOX, ensure that there are no dust particles in either connector. Replacement
antennas are available by contacting your VBOX distributor.
The antenna is a magnetic mounting type for quick and simple mounting to the vehicle roof. For optimum GPS signal reception, make sure that the antenna is
fitted to the highest point of the vehicle away from any obstructions that may block satellite reception. The GPS antenna works best with a metal ground plane
underneath (eg. Vehicle roof).
Please also note that when using any GPS equipment, a clear sky view is
important. Objects in the surrounding area such and tall buildings or trees can
block the GPS signal causing a reduction or loss in the number of satellites
being tracked.
