USB
VBOX 4 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.
ETHERNET
This is the Ethernet port which has the principal use of data output for robot operation.
ANALOGUE INPUTS
This is the analogue input port. Each of the four analogue input channels on a VBOX 4 unit has a dedicated analogue converter. Data is recorded from each channel simultaneously. The analogue input connector also provides 2 power outputs that can be used for driving sensors. 
PWR
This is the power port. VBOX 4 units can accept a supply voltage between 7 and 30 V DC. 
DGPS
This is the differential GPS port for connection to a DGPS radio for the VBOX 4 unit to receive differential GPS data for local correction. 
IMU
This is the inertial measurement unit port where you can connect a Racelogic IMU unit to the VBOX unit.
D IN

The digital input port contains the two digital inputs for the VBOX 4.

  • The event marker/brake trigger input is connected to an event capture input on the GNSS engine. This can capture the trigger event time very precisely (10 ns resolution). You can also use the available handheld event marker to 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.
AD OUT

The analogue and digital output port has the following outputs: 

  • 2 x Analogue voltage outputs. 
  • 2 x Digital outputs.
    • 1 x simple on/off state output that can be associated with any of the data channels being logged by the VBOX unit.
    • 1 x frequency/pulse output that corresponds to velocity. You can adjust the pulse per metre range in VBOX Setup.
RL CAN
This is the Racelogic CAN port which you can use to connect Racelogic modules to your VBOX 4 unit to log them to the .vbb file.
CAN
This is the CAN port that you can use to connect a third-party CAN bus to log CAN 2.0 channels to the .vbb file, and for live-data viewing.  A maximum of 32 CAN channels can be logged via this port.
CANFD 1 / CANFD 2
Input only.
For logging CAN 2.0 or CAN FD. Capable of full bus logging to a time-synchronised ASC file (one combined file for CANFD 1 and CANFD 2). Data logged via these ports can only be viewed during post-processing.
SERIAL
The serial port can be used for communication between the VBOX unit and a laptop PC. In ADAS mode, you can also use this port to connect the ADAS radio to your VBOX unit. 
ANT A
The primary antenna connector.
ANT B
The secondary antenna connector.
LOG
Indicates the logging status of the VBOX unit and if the firmware is being updated.
SATS  
Indicates the number of satellites being tracked.
DUAL 
Indicates if dual antenna mode is enabled/disabled and the antenna lock is fixed.
WIFI/BT
Indicates that the VBOX unit is waiting for connection or has been connected to a device. 
PWR 
Indicates if the unit is powered and ready to use or not.
DGPS
Indicates the DGPS status and RTK lock.
IMU
Indicates IMU integration and initialisation status. 
D IN 
Indicates activated/triggered event marker input.
You can find the full description of the different LED behaviours here.

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 SD card. Logging will now not continue, even if you are moving, until you press the LOG button again or you remove the SD card and reinsert it. The VBOX unit will then continue to log only when moving. 

Coldstart

  1. Press and hold the LOG button for 5 seconds to initiate a coldstart
  2. The unit will sound a buzzer to acknowledge the coldstart.

Factory Reset

  1. Start with the VBOX unit powered off.
  2. Press and hold the LOG button while you apply power until the unit sounds a buzzer to acknowledge the reset (this may take a while).
  3. The unit will play a tune to confirm the reset. 

This is the SD Card slot on the front panel of the VBOX 4 unit. 

You can find more information about the SD Card requirements on the Getting Started page.
