Good day to you.
I am looking for help and advice with regarding to designing and building a little opto-isolated serial interface cable.
The board that I am trying to interface to my pc with has 6 pins.
Pins3&4 have a 0-12volt signal output.
What is the best way to go about making an interface cable to connect from my PC's RS232 (com) port to the above board?
Thanks for your time.
Best Regards.

Pin1 - (RxD Positive).
Pin2 - (RxD Negative).
Pin3 - (TxD Positive).
Pin4 - (TxD Negative).
Pin5 - (Ground).
Pin6 - (+12 Output).
Pins1&2 are connected to a CNY17-3 Optocoupler via a 100R resistor.
Pin2 - (RxD Negative).
