Figure 11: Accelerometer Module Harness Connection
The optional external Accelerometer, or Inertia Sensor, must be hard mounted to the
vehicle floor, frame, or some other non-dampened part of the vehicle. If external
dampening is used for the DVR, hard mounting the accelerometer will prevent the
accelerometer readings from being compromised.
To properly install the Accelerometer Module, the user must align the device with the
picture on top of the module. The ‘X’ axis is drawn from the back to the front of the bus,
the ‘Y’ axis is drawn from the side of the bus to the other side of the bus, and the ‘Z’ axis
is drawn from the bottom to the top of the bus. After the device has been properly aligned,
the Accelerometer Module must be calibrated.
