VB3i MANUAL
Operation
Power
Included with the VBOX3i is a cigar lighter power cable, which is the primary source of power input. This is terminated
in a 2-way connector and mates with the 2-way 'PWR' socket on the VBOX3i.
The VBOX3i can be powered from a wide range of voltage sources, when considering batteries as a power source
please note that the minimum operating voltage of the VBOX3i is 7V. The maximum operating voltage input must not
exceed 30V DC. Failure to observe this could result in damage to the VBOX.
The VBOX can be connected to other Racelogic input modules including the ADC03, ADC02, TC8, FIM02/3
and multifunction display. Please note that the voltage supply to Racelogic modules connected to the VBOX
will be at the same level as the VBOX power input. Therefore when using any of the Racelogic peripherals
with VBOX3i, the input voltage must not exceed 15 volts. Failure to observe this could result in damage to
When running the VBOX from a battery pack, the VBOX will sound a warning tone to indicate when the battery
voltage is reaching the minimum operating voltage level. When this tone is heard, the battery pack requires re-
charging or replacing.
The VBOX3i has been designed to generate as little heat as possible and it has a wide operating temperature range,
however it is good practice to mount the VBOX3i in a position where it has sufficient airflow around the case.
You must connect the GPS antenna before connecting power to the VBOX3i. This is necessary because on power-up
the VBOX3i will look for a connected GPS antenna and automatically adjust its gain for optimum performance.
Buttons
VBOX3i has two membrane buttons on the front panel, LOG and FUNC. LOG is used to start and stop logging to the
compact flash card, and FUNC is used to switch between two sample rates, 100Hz and 20Hz.
LOG
The LOG button will override any of the automatic logging thresholds set in the VBOX. For example, if you have set the
VBOX to log all the time, the LOG button will toggle logging on and off. If you have set the VBOX to 'log only when
moving' and you are moving, pressing the LOG button will stop the VBOX logging and close the file on the compact
flash. Logging will now not continue even if you are moving until the LOG button is pressed again or the compact flash
card is removed and reinserted. The VBOX will then continue to log only when moving.
- Every time the logging is toggled with the LOG button, a new file is created.
- When the VBOX is logging, the blue CF light flashes.
- Do not remove the CF card or power down whilst this LED is flashing, if you need to remove the card or power
down whilst the CF light is flashing, then press the LOG button first to stop the VBOX logging. Failure to do so will
result in data loss or corruption.
FUNC
Pressing the FUNC button briefly flashes the LED's to indicate the current sample rate. A slow flash (once per second)
on all the LED's indicates 20Hz, and rapid flashing (5 times a second) indicates a 100Hz sample rate. A running
sequence of lights indicates a sample rate other than 100Hz or 20Hz. Pressing and holding the FUNC button for 5
seconds toggles the current sample rate. The sample rate can also be set in the VBOX software.
Default setup
The default factory settings are restored to the VBOX by pressing and holding the FUNC and LOG buttons for 5
seconds. This will put the VBOX3i into the default factory settings, 100Hz logging when moving, and the standard
logging parameters: sats, time, latitude, longitude, velocity, heading, height, vertical velocity, and brake trigger event
time. (DGPS will be off by default.).
