3.8 LIN / RS-232 UART
There are three UART connectors X1, X4 and X8 (9-pin D-Sub) on-board, which can be
used for RS-232 or LIN communication (to get information in detail about pin usage, please
refer to chapter 4.2 UART / LIN Connector (X1, X4, X8)). The LIN transceiver needs to be
configured as LIN-master or LIN-slave.
