This header configures the Primary UART port connector (CN1), selection of the
headers allows the connector pin-out to be changed to support one of the
following configurations:
 RS232 DTE
 RS232 DCE
 RS422/485 4-wire
 RS422/485 2-wire
For each of the configurations please note there is a pin out change and it may
be necessary to alter the cable being used for connection to the serial host. The
different configurations of jumpers and pin outs can be seen in Table 17.
It is not possible to independently select the transceiver type for each UART port
(CN1 and CN2) consequently both ports must be the same type (RS232 or
RS422/485).
