  • Page 9: Can Termination

    User Manual - QG65D J1939 Dynamic Inclinometer (Type JA) V1.0 4.4. CAN termination A CAN bus should be terminated properly to prevent signal reflections. The QG65D dynamic Inclinometer has an internal 120 Ohm termination resistor. By default, this is disabled.

  • Page 10: Functional Description

    The QG65D dynamic inclinometer combines accelerometer MEMS and gyro MEMS. This device is unaffected by vibration or movement and can therefore measure the true angle at the sensor position in real time. Our smart algorithms (such as Kalman filtering) within the device can determine the balance between the accelerometer MEMS (best result in static situations) and the gyro MEMS (best result in dynamic situations).
