4. General Description
The radio frequency transceiver is part of a body computer ECU. The ECU incorporates several HWinputs and HW-outputs, which monitor and control body computer functionalities in a car (e.g. light
control and central door locking).
The ECU consists of a plastic housing, PCB, electronic components and connector pins.
The radio frequency transceiver functionality will be explained in more detail in the below documented
sections.
5. HW Interface
The radio frequency transceiver is supplied via the specified connector pins.
The antenna of the radio frequency transceiver is a PCB-edge antenna, which is incorporated in the
PCB of the ECU.
