grab a meter, as long as the cable is one to one, you're ok.
that being said, the red stripe usually indicates the pin one side of the connector, and indeed the red conductor is usually pin one.
but this may not always be the case. however, on a db25, yes, the first conductor would be pin one, while the second would be pin 14. but, always check first, two minutes of troubleshooting is worth the cost of your sexy, sexy interface.
and remember, you can always make a continuity tester.
