RS232-Enable Pin Header, P5
GPIO Port, P7
21
P5 is used to enable or disable serial port RS232s transceiver. Shorting P5 pins 1 and 2 will
enable the RS232 transceiver. Shorting P5 pins 2 and 3 will disable the RS232 transceiver.
The GPIO port is a 9-pin male right-angle connector that is labeled as P7 on the
development board. See the following figure for pin orientation; see the following tables
for pin assignments. For input and output threshold specifications, see "DC Characteristics"
on page 39. Note that each signal has a 220 ohm series resistor between the P7 pin and the
module (except GND).
