3.4 UART"A"

One RS232-transceiver (U5, X6) can be connected to one of the microcontroller's UART
interfaces.
JP26, JP29 connect UART 3 to the RS232-transceiver (U1, X3)
JP24 Some programs (e.g. Terminals) need a connection between CTS and RTS
Jumper
JP26 (UART"A"RxD)
JP29 (UART"A"TxD)
JP24 (RTS-CTS)
Default: grey

3.5 UART"B" / LIN "A"

One RS232-transceiver (U7) or one LIN-transceiver (U6) can be connected to one of the
microcontroller's UART interfaces. Connect to D-Sub X8 corresponding RS232 or LIN cable.
By default RS232 is selected to X8.
JP42 Selects if RS232 or LIN is connected to SIN7 of MCU
JP44 Selects if RS232 or LIN is connected to SOT7 of MCU
JP40 Selects if UARTB or LINA is connected to pin2 of X8
JP49 Some programs (e.g. Terminals) need a connection between CTS and RTS
JP37 Enable LIN-Transceiver
JP32 Selects LIN Master mode
JP38 Connects Vs (Pin 1 of X8) to Vin
