IA serial ports use a standard configuration that allows direct connection to a PC via a FEMALE to MALE serial cable. It uses only
three pins (Transmit, Receive, Ground).
The pin configurations are:
IN:
Pin 2 = Transmit
Pin 3 = Receive
Pin 5 = Ground
OUT:
Pin 2 = Receive
Pin 3 = Transmit
Pin 5 = Ground
