You can find more information about the different inputs and outputs here.

BLUETOOTHVBOX 3i ADAS comes equipped with a Bluetooth radio allowing configuration of the VBOX unit remotely along with remote output of real-time VBOX serial data, at the full 100 Hz data rate, to any Bluetooth capable PC or data logger.
A INThis is the analogue input connector. Each of the four analogue input channels on VBOX 3i ADAS has a dedicated analogue converter. Data is recorded from each channel simultaneously to avoid latency between analogue channel data. The analogue input connector also provides two power outputs that may be used for driving sensors.
PWRThis is the power connector. VBOX 3i ADAS can accept a supply voltage between 7 and 30 V DC. Low current consumption results in extended battery life.
DGPS

The RS232 port named DGPS is designated for connection to a DGPS radio, allowing the reception of Differential GPS (DGPS) data for local correction.

SERThe primary RS232 port is used for all communication between the VBOX 3i ADAS unit and a laptop PC. The primary port is marked SER on the front panel of the VBOX 3i ADAS. In ADAS mode you can use this port with an ADAS radio.
D IN

The ‘D IN’ connector contains the two digital inputs for the VBOX 3i ADAS.

  • The event marker input is connected to an event capture input on the GNSS engine. This captures precisely the trigger event time (10 ns resolution). A handheld event marker is also available so that you can record marker events in the data file.
  • A remote logging on/off switch is also available for ease of use and in situations when the front panel switch is not easily accessible.
RLCANThis connector is termination-enabled and is to be used with Racelogic modules and devices.
CANThe CAN port is used for Racelogic CAN output and for logging third-party CAN data to the .vbb file.
AUDIOVBOX 3i ADAS can record audio tags synched with a set GNSS timestamp, with an accuracy of 0.5 seconds.
USBVBOX 3i ADAS includes a USB 2.0 connection that you can use to configure your VBOX unit and output real-time serial data at the full 100 Hz data rate
ANTENNA AThe primary antenna connector.
ANTENNA BThe secondary antenna connector.


CFIndicates that the unit is writing to the Compact Flash card.
LOGIndicates that the unit is capturing data to the CF card and the current logging rate.
SATSIndicates the number of satellites being tracked.
DUALIndicates whether dual antenna mode is enabled/disabled and that antenna lock is fixed.
DIFFIndicates the DGPS status.
IMUIndicates the IMU integration and initialisation status.
BLUETOOTHIndicates that communication has been initialised and that Bluetooth connection has been confirmed.
PWRIndicates whether the unit is powered and ready to use or not.
SERIndicates incoming serial traffic and that data has been decoded and is being logged.
D INIndicates activated/triggered event marker input.
RLCANIndicates that expected incoming CAN data has been decoded properly and is being logged.
CANIndicates that expected incoming CAN data has been decoded properly and is being logged.

This is the CF Card slot on the front panel of the VBOX 3i unit. It accepts Type I compact flash cards to log data.


VBOX 3i units 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, 100 Hz and 20 Hz.

The LOG button will override any of the automatic logging thresholds set in the VBOX unit. For example, if you have set the VBOX unit to log all the time, the LOG button will toggle logging on and off. If you have set the VBOX unit to ’log only when moving’ and you are moving, pressing the LOG button will stop the VBOX unit logging and close the file on the compact flash card. Logging will now not continue, even if you are moving, until you press the LOG button again or you remove the compact flash card and reinsert it. The VBOX unit will then continue to log only when moving. 

Press and hold the LOG button for 5 seconds to initiate a coldstart

Pressing the FUNC button briefly flashes the LOG LED and beeps to indicate the current sample rate. A slow flash (once per second) indicates 20 Hz, and rapid flash (5 times a second) indicates a 100 Hz sample rate. Pressing and holding the FUNC button for 5 seconds toggles the log rate between 20 Hz and 100 Hz. The sample rate can also be set using VBOX Manager or VBOX Setup.


You can restore the default factory settings on VBOX 3i unit by pressing and holding the FUNC and LOG buttons simultaneously for 10 seconds. This will trigger the reset process. There will be an audible notification beep and tune playing when the process has completed.
