Page 7: 7 Sae J1939 Interface
Inclination sensor JN 7 7 SAE J1939 interface The inclination sensors have a standardised SAEJ1939 interface. All measured values and parameter groups can be accessed via the J1939 protocol. The individual configuration can be saved in the internal permanent memory (flash). 7.1 Overview and structure of the SAE J1939 protocol The SAE J1939 protocol uses a 29-bit CAN identifier (extended frame format CAN 2.0B). -
Page 8: Proprietary Pdu Format 1 Protocol
Inclination sensor JN 7.2 Proprietary PDU format 1 protocol The parameters of the JN2301 sensors are listed in a table that is accessed per 16-bit index. To access the sensor parameters in reading or writing the proprietary PDU format 1 message is used. PDU format (PF) corresponds to the value 0xEF. -

Page 14: Euler Angle (0X2044 = 1)
Inclination sensor JN The second provided value corresponds to a rotation about the X axis of the sensor and is called "lateral inclination value". The value corresponds to the angle [°] between the gravitation vector and the XZ plane of the sensor. In the case of an inclination in a plane (rotation of an axis with the second axis remaining perpendicular) the perpendicular angle and gimbal angle are always identical. -
Page 15: Gimbal Angle Y (0X2044 = 3)
Inclination sensor JN – Inclination value longitudinal: -45°…+45° – Inclination value lateral: -45°…+45° Critical point With a longitudinal inclination of ± 90° ("plane" flies vertically downwards or upwards) the roll angle makes a rotation about the gravitational axis which cannot be detected by the inclination sensor. -
Page 16: Other Sensor Functions
In the case of a change the device address and baud rate do not become effective until after a reset (reset application, reset communication or hardware reset). The inclination sensor from ifm is delivered with the device address (ECU) 25 and a baud rate of 250 Kbits/s. -
Page 17: Set Zero Point (0X2046)
Inclination sensor JN 10.4 Set zero point (0x2046) To set the zero point the sensor is rotated to the requested position and the current position is set as "0". The value of the parameter "set zero point X and Y axes" (index 2046h) is to be set to 1. -
Page 18: Quadrant Correction (0X2040)
-30° 0° 10.7 Quadrant correction (0x2040) Quadrant correction means for JN2301 only an extension of the lateral Euler angle to the measuring ranges ± 180° (corresponds to 2040h = 1) or 0...360° (corresponds to 2040h = 2). 10.8 Heating (0x2041) To ensure good temperature stability over the whole temperature range, the measuring cell is regulated to a constant temperature using a PID controller. -

Inclination sensor JN 10.9 MEMS measuring cell temperature (0x2081) The temperature of the measuring cell is determined every 200 ms and updated in the protocol at "informative". It can be read via access to the index 0x2081 The signed 16-bit value indicates the temperature in °C. 10.10 MEMS self-test (0x4008 / 0x4009) To check the function of the measurement axes a self-test of the measuring cell can be carried out. -
