I am not exactly sure if this is what you are asking but the 15 pin joystick ports on the OI are NOT serial (e.g. RS-232) they are analog. There seems to be a common misconception that the joystick ports on the OI are serial. They are compatible with the old DOS 15 pin analog joysticks. Good luck finding those these days. A USB to serial converter converts USB to RS-232 and will not work at all to make a modern USB joystick work with a OI. In fact, they are not even the same connector. The USB-serial converters are usually 9-pin and the Joystick ports are 15-pin. And no, you cannot make a 9-pin to 15-pin conversion cable work either because there is no serial data coming out of the joystick only analog values from the potentiometers and digital switch contact closures.

I am just trying to shed some light on what I have seen to be a common misconception about these joystick ports. Not picking on you.
