4 Connectors
4.1 Power Connector (X5)
The following figure shows the power connection jack of the Starterkit. This connector is
used to connect an external unregulated DC power supply voltage (9V-12V DC
recommended 2000mA).
4.2 UART / LIN Connector (X1, X4, X8)
Three 9-pin D-Sub female connectors are used for the serial interfaces LIN/UART2,
LIN/UART4 and LIN/UART5.
Take care, that the RS232 as well as the LIN signals are shared at the connectors and have
to be selected by jumpers (see chapter 3.4).
