Com Por t Setup

Use standard communications settings: Baud Rate: 9600, Data Bits: 8, Parity: None, Stop

Bits: 1

SC IN and OUT Por t Pin Configuration

SC 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
