Setup
Hardware
IMPORTANT
The IMU04 must be connected to the VBOX 3iS before you apply power. This is to ensure that the data is
correctly synchronised.
1. Fit your VBOX 3iS in the test vehicle, and mount the IMU
.
2. Connect the antenna to the VBOX 3iS.
3. Use the RLCAB131 cable to connect the left-hand
CAN/KF
port on the IMU to the
AUX
lead of the cable loom
connected to the VBOX 3iS.
4. Measure the
Antenna to Ref/IMU Offsets.
You can find more information on this
.
◦ Roof Mounted: If required, take data translation measurements in the X, Y and Z axes from centre of IMU.
This is by default set to 1 m directly beneath the IMU when Roof Mount is 'Enabled'.
◦ In-vehicle mounted: Measure the relative position from the top centre of the GNSS antenna to the top centre
of the IMU. You must measure all 3 axes, X, Y and Z.
5. After the IMU04 is connected, you can apply power to the VBOX 3iS.
6. Enable
External IMU Integration
and enter the
Antenna to Ref/IMU Offsets.
You can do this using the
VBOX Setup Software
, the
Front Panel
of the unit, or with
VBOX Manager
.
