2.3.6 P10, RS-232 Connector
The eZdsp F2804x has an RS-232 connector which brings out the SCIA transmit and
receive signals to be used as UART. This UART uses the MAX3238 RS-232 line driver
and is routed to a male 9 pin D-connector, P10. The pin positions for the P10 connector
as viewed from the edge of the printed circuit board are shown below.
The pin numbers and their corresponding signals are shown in the table below. This
corresponds to a standard dual row to DB-9 connector interface used on personal
computers.
