Setup
Important note: IMU04 must be connected to VB3i before power is applied to ensure data is correctly synchronised.
1. Mount the VB3i and IMU in test vehicle. The IMU should be mounted rigidly to the vehicle mid-way along the
wheelbase in the direction of vehicle travel.
2. Fit VB3i GPS, GPS/GLONASS antenna to centre of vehicles roof. Connect antenna to VB3i.
3.
Measure the relative position from the top centre of the GPS antenna to the top centre of the IMU (see mounting
section for more detail) and enter these distances in the highlighted box below.
4. IMU04 – Connect CAN/KF port to VB3i-V3 25W D analogue input port using RLCAB119 cable.
4.
IMU03 – Connect either port on IMU to VBOX RL CAN port using RLCAB005-CS cable.
5. After IMU is connected, apply power to VB3i.
6. Connect VB3i to PC using RLCAB001 or RLCAB066-2 cable (RS232 or USB).
7. Open VBOX Tools and VBOX Setup.
8. Tick ‘Use IMU’ box
and enter the distances
measured from GPS
antenna to the IMU.
Important notes:
1. To use IMU04 integration, a
VB3i-V3
must be used.
This is an IMU04 enabled unit.
2. IMU04 cannot be used with IMU integration if it is connected to a VBOX via CAN (RLCAB120 / RLCAB005-CS).
This method of connection will only allow standard IMU channels to be logged. See ‘using IMU as CAN module’
section for details.
3. The IMU04 standard channels can also be logged when the IMU04 is connected via KF port with cable
RLCAB119, without enabling IMU integration.
