The embedded motion sensor itself shall be connected to the VU, so that the interface between the VU and the adaptor shall be compliant with the requirements set out in ISO16844-3.\n2.2.\nFunctions\nADA_003\nThe adaptor shall include the following functions:\ninterfacing and adapting the incoming speed pulses,\ninducing the incoming pulses to the embedded motion sensor,\nall functions of the embedded motion sensor, providing secured motion data to the VU.\n2.3.\nSecurity\nADA_004\nThe adaptor shall not be security certified according to the motion sensor generic security target defined in Appendix 10 of this Annex. Security related requirements specified in section 4.4 of this Appendix shall apply instead.\n3.\nREQUIREMENTS FOR THE RECORDING EQUIPMENT WHEN AN ADAPTOR IS INSTALLED\nThe requirements in the following Chapters indicate how the requirements of this Annex shall be understood when an adaptor is used. The related requirement numbers of Annex IC are provided between brackets.\nADA_005\nThe recording equipment of any vehicle fitted with an adaptor must comply with all the provisions of this Annex, except otherwise specified in this Appendix.\nADA_006\nWhen an adaptor is installed, the recording equipment includes cables, the adaptor (including a motion sensor), and a VU [01].\nADA_007\nThe detection of events and/or faults function of the recording equipment is modified as follows:\nthe ‘power supply interruption’ event shall be triggered by the VU, while not in calibration mode, in case of any interruption exceeding 200 milliseconds of the power supply of the embedded motion sensor [79]\nthe ‘motion data error’ event shall be triggered by the VU in case of interruption of the normal data flow between the embedded motion sensor and the VU and/or in case of data integrity or data authentication error during data exchange between the embedded motion sensor and the VU [83]\nthe ‘security breach attempt’ event shall be triggered by the VU for any other event affecting the security of the embedded motion sensor, while not in calibration mode [85]\nthe ‘recording equipment’ fault shall be triggered by the VU, while not in calibration mode, for any fault of the embedded motion sensor [88]\nADA_008\nThe adaptor faults detectable by the recording equipment shall be those related with the embedded motion sensor [88].\nADA_009\nThe VU calibration function shall allow to automatically pair the embedded motion sensor with the VU [202, 204].\n4.\nCONSTRUCTION AND FUNCTIONAL REQUIREMENTS FOR THE ADAPTOR\n4.1.\nInterfacing and adapting incoming speed pulses\nADA_011\nThe adaptor input interface shall accept frequency pulses representative of the vehicle speed and distance travelled. Electrical characteristics of the incoming pulses are: TBD by the manufacturer. Adjustments accessible to only the adaptor manufacturer, and to the approved workshop performing the adaptor installation shall allow the correct interfacing of the adaptor input to the vehicle, if applicable.\nADA_012\nThe adaptor input interface shall be able, if applicable, to multiply or divide the frequency pulses of the incoming speed pulses by a fixed factor, to adapt the signal to the k factor range defined by this Annex (4 000 to 25 000 pulses/km). This fixed factor may only be programmed by the adaptor manufacturer, and the approved workshop performing the adaptor installation.\n4.2.\nInducing the incoming pulses to the embedded motion sensor\nADA_013\nThe incoming pulses, possibly adapted as specified above, shall be induced to the embedded motion sensor, so that each incoming pulse shall be detected by the motion sensor.\n4.3.\nEmbedded motion sensor\nADA_014\nThe embedded motion sensor shall be stimulated by the induced pulses, thus allowing it to generate motion data accurately representing the vehicle movement, as if it was mechanically interfaced to a moving part of the vehicle.\nADA_015\nThe identification data of the embedded motion sensor shall be used by the VU to identify the adaptor [95].\nADA_016\nThe installation data stored in the embedded motion sensor shall be considered to represent the adaptor installation data [122].\n4.4.\nSecurity requirements\nADA_017\nThe adaptor housing shall be designed so that it cannot be opened. It shall be sealed, so that physical tampering attempts can be easily detected (e.g. through visual inspection, see ADA_035). Seals shall follow the same requirements of motion sensor seals [398 to 406]\nADA_018\nIt shall not be possible to remove the embedded motion sensor from the adaptor without breaking the seal(s) of the adaptor housing, or breaking the seal between the sensor and the adaptor housing (see ADA_034).\nADA_019\nThe adaptor shall ensure that motion data may only been processed and derived from the adaptor input.\n4.5.\nPerformance characteristics\nADA_020\nThe adaptor shall be fully operational in the temperature range defined by the manufacturer.\nADA_021\nThe adaptor shall be fully operational in the humidity range 10 % to 90 % [214].\nADA_022\nThe adaptor shall be protected against over-voltage, inversion of its power supply polarity, and short circuits [216].\nADA_023\nThe adaptor shall either:\nreact to a magnetic field disturbing vehicle motion detection.
