RS232 Interface
The BeagleBone RS232 Cape uses the SN65C322EPW to provide an RS232 serial
interface for BeagleBone. SN65C322EPW features one line driver and one line receiver
to translate data from RS232 level to UART level and vice versa. The RS232 signals are
connected to TX and RX pins of D-Sub9 serial connector on the board. The UART
signals are connected to four different UART ports on the BeagleBone via selection
jumpers.
