How do I connect the SCI channel directly to a Personal Computer?

Latest Updated:03/18/2009

Question:

How do I connect the SCI channel on my device directly to a Personal Computer ?

Answer:

The most common solution to this is to connect the Transmit and Receive pins via a RS232 device to a 9 way D-type connector. The RxD pin of the device should connect to the TD (pin 3) of the 9 way connector and the TxD pin of the device should connect to RD (pin 2). This is for a 1:1 conncetion. This is for asynchronous comms only.
