RS232-enable pin header, P5
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.
GPIO port, P7
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. Note that each signal has a 220 ohm series
resistor between the P7 pin and the module (except GND).
Note The development board is shipped with a 9-pin screw-flange plug attached to the GPIO port.
