FlexRAY Configuration
The EVB is fitted with two FlexRAY transceivers, a female DB9 connector (for both transceivers) and
two alternative connectors. Jumpers J27 and J30 are provided to route the respective MCU signals to the
physical interfaces.
The pin-out of the DB9 connector (J2) is shown in
Figure 10.

For flexibility, the FlexRAY transceiver is also connected to two FlexRAY connectors (P1 & P2) and
two 2pin Molex connectors (J1 & J3, not populated by default) at the top side of the EVB. Figure 11
shows the connections for both types of connectors.
