4 Connectors

4.1 Power Connector (X5)

The following figure shows the power connection jack of the starter kit. 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 3.8).
