Robin, QHY DB9 to RJ12 is a DB9 to 6pin 6Connector jack (6P/6C). There is very little (read "none") conformity on how the RJ pins are arranged, each mfger does their own thing.....which can be a real issue if you use the wrong cable.

Anyway, FWIW, I don't have a QHY wheel but I did make a Bluetooth unit to drive one and I used this config. Please double check with someone else.
