VBOX 3i Dual Antenna - front view.png

Connectors

You can find more information about the different inputs and outputs here.
BLUETOOTH VBOX 3i units come equipped with a Bluetooth radio allowing configuration of the VBOX unit remotely along with the remote output of real-time VBOX serial data, at the full 100 Hz data rate, to any Bluetooth capable PC or data logger. 
A IN

This is the analogue input connector. Each of the four analogue input channels on a VBOX 3i unit has a dedicated analogue converter. Data is recorded from each channel simultaneously. The analogue input connector also provides two power outputs that may be used for driving sensors. 
PWR This is the power connector. VBOX 3i units can accept a supply voltage between 7 and 30 V DC. 
AD1 The AD1 port has 1 analogue voltage and 1 digital output. The digital output is a simple on/off state output that can be associated with any of the data channels being logged by the VBOX. You can set a threshold level for the selected data channel, where a true condition gives a 5 V output and a false condition gives a 0 V output. You can also associate hysteresis and tolerance values with this condition. The default function of this digital output is to indicate the current logging status of the VBOX.
AD2

The AD2 port has 1 analogue voltage and 1 digital output. The digital output is a frequency/pulse output that corresponds to velocity. You can adjust the pulse per metre range in the software. The voltage range of the analogue output is 0 to 5 V DC.
D IN

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

  • The event marker/brake trigger 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.
CAN* The secondary RS232 port is used for connection to a Telemetry Radio module allowing the reception of Differential GPS (DGPS) data for local correction from a Racelogic Local DGPS base station, or Moving Base solution. The secondary RS232 port is located in the connector marked CAN on the VBOX 3i front panel.
SER*

The primary RS232 port is used for all communication between the VBOX 3i unit and a laptop PC. The primary port is marked SER on the front panel.  

Note: Due to the max bandwidth being 115200, live data transfer of all channels is limited to 20 Hz. 50 Hz should only be used to transmit standard GPS channels and Solution Type, and 100 Hz can only transmit Sats, Time, Speed, and Trigger Event Time. Logging too many channels at too high a rate will cause drop-outs and loss of data. For maximum accuracy, you should log tests performed at a GPS sample rate above 20 Hz to compact flash and do a post-process analysis. 
AUDIO VBOX 3i units can record audio tags synched with a set GNSS timestamp, with an accuracy of 0.5 seconds.
USB

VBOX 3i units include 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 A The primary antenna connector.
ANTENNA B The secondary antenna connector.

*You can configure the function of the CAN and SER ports with VBOX Setup and swap the Racelogic Bus profile. The Racelogic CAN bus is used for connected Racelogic modules or displays. The Vehicle CAN bus (VCI) is for use by third-party CAN equipment, whether you are logging to or from the VBOX. For dual use of RS232 and CAN from one of the sockets you will need to use a 5-way Lemo splitter (RLVBACS024).

IMPORTANT

Power supplied to external Racelogic CAN modules through the CAN or SER cables is at the same voltage as the input power supply. When you are using Racelogic external CAN modules (eg; MFD or ADC03), you must make sure that the VBOX 3i supply voltage does not exceed 15 V DC.

LEDs 

CF  Indicates that the unit is writing to the Compact Flash card.
LOG  Indicates that the unit is capturing data to the CF card and the current logging rate.
SATS   Indicates the number of satellites being tracked.
DUAL  Indicates whether dual antenna mode is enabled/disabled and that the antenna lock is fixed.
DIFF  Indicates the DGPS status.
IMU  Indicates the IMU integration and initialisation status.
BLUETOOTH  Indicates that communication has been initialised and that Bluetooth connection has been confirmed.
PWR  Indicates whether the unit is powered and ready to use or not.
D IN  Indicates activated/triggered event marker input.
CAN  Indicates that expected incoming CAN data has been decoded properly and is being logged.
SER  Indicates  incoming serial traffic and that incoming CAN data has been decoded and is being logged.
You can find the full description of the different behaviours of the LEDs here.
Compact Flash 
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. 
Buttons
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.
LOG 

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. 

Notes: 

  • If the VBOX unit is using ‘log only when moving’ log mode, and the vehicle has been stationary from power-up, the LOG button will not initiate logging. If you want the VBOX unit to log in this situation, you have to use VBOX Manager or VBOX Setup to change the log mode to ‘Log Continuous’.
  • Every time the logging is toggled with the LOG button, a new file is created.
  • When the VBOX unit is logging, the green LOG LED will be solid and the blue CF light will flash.

Coldstart

Press and hold the LOG button for 5 seconds to initiate a coldstart. 
IMPORTANT
Do not remove the CF card or power down the unit while the CF LED is flashing. If you need to remove the card or power down the unit and the CF LED is flashing, you must press the LOG button first to manually stop the VBOX unit from logging. If you don't do this you can lose the data or corrupt the card.
FUNC 

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.
Default 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.
