  • You can access the menu by pressing the OK button.
  • Use the Up and Down arrows to navigate through the menu and press the OK button to enter a submenu or change a setting.
  • When editing a setting, the Up and Down buttons will let you scroll through the available options for that setting and the OK button will confirm your selection.
  • Use the Back button to exit a setting. 
This menu can be used to configure the internal IMU settings.

This setting enables or disables Kalman Filter Wheel Speed Input.

If the unit cannot detect CAN data, you will see a status message on the front panel.

This action will add the Wheel Speeds channel to CAN ID 31D. 

VBOX Omega IMU  - Wheel Speed Enabled

This setting enables or disables Kalman Filter Wheel Speed Input.

If the unit cannot detect CAN data, you will see a status message on the front panel.

This action will add the Wheel Speeds channel to CAN ID 31D. 

VBOX Omega IMU  - Wheel Speed Enabled

This setting specifies the X, Y, and Z distances between the antenna and the wheel speed reference point. 

The reference point is the centre point between the rear wheels.

VBOX 3iSDR IMU_Ant to Wheel Offset (Framed)

This setting specifies the X, Y, and Z distances between the antenna and the wheel speed reference point. 

The reference point is the centre point between the rear wheels.

Ant to IMU Offset

Provides the X, Y, and Z offset values from the antenna to VBOX Omega that is required for the Kalman Filter algorithm.

IMU to Ref. Offset

This is where you can add the X, Y, and Z offset values from the IMU to the nominated reference point where all measurements will be made.

Select the orientation of the side of VBOX Omega facing down. This is only applied once the IMU menu is exited to the Main Menu. When the orientation is changed, the Kalman Filter is reset.

VBOX 3iSDR IMU_Side Facing Down_F_Selected (Framed)

Select the orientation of the side of VBOX Omega facing down. This is only applied once the IMU menu is exited to the Main Menu. When the orientation is changed, the Kalman Filter is reset.

VBOX 3iSDR IMU_Side Facing Down_F_Selected (Framed)

Select the orientation of the side of VBOX Omega facing forward. This is only applied once the IMU menu is exited to the Main Menu. When the orientation is changed, the Kalman Filter is reset.

VBOX 3iSDR IMU_Side Facing Forwrd_A_Selected (Framed)

Select the orientation of the side of VBOX Omega facing forward. This is only applied once the IMU menu is exited to the Main Menu. When the orientation is changed, the Kalman Filter is reset.

Auto Level - Begins the process of levelling the IMU calculated Pitch and Roll Angles. Once selected, the unit averages the pitch/roll angles over a 5-second period and will then subtract/add the averaged values to make the pitch/roll angle 0. This offset will be displayed on the main screen.

Clear - Clears the current pitch/roll offset values.

Gyro Offset

Auto Level - Begins the process of levelling the IMU calculated Pitch, Roll and Yaw Rates. Once selected, the unit averages the rates over a 5-second period and will then subtract/add the averaged values to make the rates equal to 0. These offsets will be displayed on the main screen.
