Hardware Setup
Initialisation
When using IMU integration, an initialisation phase is required when the IMU is first connected to the VBOX after
being set up. This will be run through automatically after the VBOX has successfully gained satellite lock. When the
IMU LED on VB3i front panel has turned a flashing green, the initialisation is complete. Note, if you are using a VB3i-
V1, which has no IMU LED, read the LED indicators section below for LED behaviour.
LED indicators (VB3i V2/V3)
Temperature checks. If temperature
outside optimum operation range, LED
will remain orange.
Using IMU integration, inertial data being
sent to host VBOX via RS232.
Inertial data being sent to host system via CAN.
IMU enabled,
no IMU
connected.
SAT lock OK. 30 second stationary
initialisation in progress. If vehicle
moves, LED will continue to flash until 30
seconds stationary completed.
Initialisation complete –
movement not yet
detected.
Movement detected –
IMU integration working
OK.
LED indicators (VB3i V1)
When the filter is enabled and the IMU is connected, the satellite LED will remain off to act as an indicator for the IMU
integration status. Only when the filter is initialised and movement is detected will the SAT LED return to its normal
operation.
The user will need to leave 1 minute after powering the VBOX on with the IMU connected before starting to move.
This occurs on every power up of the VBOX unit.
