Please help; I bought a pair of SNK LS-30 rotary joysticks and an Ultimarc rotary interface but I don't have the cables to attach the joysticks. I got a nice substitute cable with 13 female connectors on each end for 13 discrete wires, but I am not sure of the pinout. The wires apparently do not go "straight across" as with a ribbon cable where 1 is to 1, 2 is to 2, and so forth. I have done some research and figured out that the center pin on the joystick (the pins are unmarked but it would be #7 going from either direction) is ground, as is pin #1 for the Ultimarc interface (folks at Ultimarc have been very helpful and responsive as is there reputation, but we still haven't figured out exactly where the wires go). Apparently the cable is a standard Happ rotary interface cable that I just can't seem to get on the internet at all (ebay UK has one set but will not sell internationally). Could the folks who have genuine rotaries do me a solid and just look at one of their cables and give me some clue, or even a picture or two. I actually did a PSD of a wiring attempt that I made but it actually didn't work, but it could help someone who knows what's what tell me what to do. See attached. Ryan |

Check out this post for a LS-32 to Ultimarc Rotary Interface pinout. :cheers: Scott |

Scott: Thanks a bunch! I had seen that post before but I just remember the cabinet and button related stuff and completely missed the wiring. It worked like a charm! I ordered a premade ribbon extension cable where you can tear off just what you need; it works perfectly and my colors even matched that of the poster (ordered it on Amazon) :notworthy:. Now on to the rest of the cab. One note of clarification; I could find no markings on either device to indicate pin #1; pin #! for the interface is right next to the P1 and P2 designations; and pin #1 for the joystick is on the LEFT if the joystick is in upright (playable) position with the pins facing you.

Do you mind taking a picture of your interface and labeling pin 1 for Player1 and for Player2? (similar to the pic in OP) It would be a great addition to the wiki rotary encoders entry, with your permission. Scott |

Sure, I will change my PNG and repost. Ryan |
