To facilitate unit configuration, VBOX 3iS units have an OLED display and four membrane buttons on the front panel.

Alternatively, you can use VBOX Manager to configure the VBOX 3iS unit. VBOX Manager will mirror the functionality of the front panel on the VBOX 3iS.

When the unit has initialised and any warnings have been cleared, the number of satellites will be displayed.

Note: If you have enabled IMU integration, you will also see the KF/speed quality accuracy displayed here.

If you have enabled IMU Integration, the main screen should show an indication of the Kalman Filter status.

  1. Once the unit has acquired satellite lock, the display will read Filter Initialising - Remain Stationary for 30s.
  2. The message will count down to 0 seconds and change to Stationary Initialisation Complete
  3. After 2 seconds, it will display Waiting For Movement.

Note: If the speed rises above 0.8 km/h at any stage during the steps above, the countdown and filter initialisation will reset and the following message will be displayed: Speed >0.8kph – Initialisation reset.

When the unit has detected the speed, the display will show an indication of the Kalman Filter quality in relation to the Speed Quality Channel output on CAN ID 0x306. The display will read either:

  • Low Accuracy when the speed quality is >0.1 km/h.
  • Medium Accuracy When the speed quality is <0.1 km/h.
  • OK When the speed quality is <0.06 km/h for at least 5 seconds.
You can reset the unit to its factory settings by pressing the Up and Down arrow buttons simultaneously and holding them for 5 seconds. After this period, the unit will beep and it will play an audible confirmation signal when the reset is finished.

Note: Receiver settings (Dynamic Mode, DGNSS Mode, DGNSS Rate and Elevation mask) will not reset.
