2.2 RFID DESS Post
As illustrated in Figure 4 and Figure 5, the Post is composed of a plastic cover, an O-ring,
a main PCB, a header, a secondary PCB and a plastic housing.
The plastic cover, plastic housing and O-ring protect the internals from the external
environment.
The cover provides a mechanical mating interface for a connector. The CAN variant has
a 5-pin connector, the MOWP variant has a 4-pin connector. Those overmolded pins are
providing the electrical path between the main PCB and the vehicle’s harness connected
to the ECU.
The secondary PCB is mounted to the main PCB using a 3-pin header. The secondary
PCB holds the hall sensor. The main PCB holds the remaining electronics needed for
operation: power supply, microcontroller, communication transceiver, contact output
circuitry, RFID initiator/reader and antenna.
