Note: When connecting to the RS232 signals on header A: You must connect pin 10 (PRS) to pin 11
(VCC). This powers the RS232 chip. Also make sure that R6 and R8 are installed (default condition).
Header B
Note: To use Header B you must remove resistors R6 and R8. Removing these resistors disconnects
the RX (header A pin 4) and CTS (header A pin 7) signals from the RS232 chip.
