RS-232 Serial Port
The development board uses a MAX232 transceiver chip and a 9-pin
D-SUB connector (Figure 2–25) for RS-232 communications.
fFor detailed information on how to use the transceiver, refer to the BoardDesignFiles\Datasheet folder in the kit installation directory or connect to the manufacturer’s web site.
