how to configure pad

[Oolong]

hi, i just got a playstation -> serial converter and have plugged my dance pad in (the lights are working, i know that for sure) but i can't figure out how to get the pad to correspond to different keystrokes. it didn't come with any instructions. can someone help me out? (if this was answered in a previous post than link me and lock please )

i suppose i should clarify... when i go into the driver configuration and press one of the arrows, it like makes other random keys go off at random times instead of the one i want. it's like impossible to play. should i get a different driver, different pad, different adapter or am i just doing it wrong?
