RESOLVED U360 no buttons working

[Diewrecked]

Hi guys

Hope someone can help with this.

I have two U360's and both are working fine. However I am trying to wire up the button harnesses but none of the buttons work (I am doing the first one, haven't got to the second one yet).

I've cabled according to the below from http://ultimarc.com/ultrastik_inst.html :

Pin    Wire    Input Mode    
2    Black    COM Connect to COM terminals on all buttons - daisy chained
3    Brown    Button 1 NO    
8    Blue    Button 2 NO
5    Orange    Button 3 NO    
6    Yellow    Button 4 NO    
7    Green    Button 5 NO    
4    Red    Button 6 NO    
10    Grey    Button 7 NO    
9    Violet    Button 8 NO

Like I said none of the buttons work (even if the daisy chain on the GND failed somewhere I'd expect at least button 1 to work). I've checked in the Gamepad applet in Control Panel but none of the 8 buttons light up when you press them (I assume they're supposed to?) and MAME doesn't pick them up when I try to assign them in the Game Controls menu.

Any ideas please? Am I doing something I'm not supposed to - or not doing something I am? There' s nothing on that page about telling the U360 the harness is there, or what mode it's in (the page linked above just says "This 10-pin header can be used in two modes. The post auto-detects which mode you are using." - not sure what that means? BIOS POST???)

I don't know if this matters but I also have a JPAC solely to connect the arcade monitor and speaker connectors via JAMMA, but which is also using one key for Coin, and an OptiPAC for a trackball (no buttons).

Thanks in advance you guys.

Cheers

You shouldn't have to do anything other than wire up the buttons and connect the harness, and yes, the buttons should light up in the gamepad applet when you press them. Not sure what to suggest - got any pics of your installation?

Thanks for your reply.

Pics as requested. The last one is at an angle so you can see the coloured cables going to the NO terminals on the switches.

I see the black wire going off and away from the stick in the last picture.  Where have you got it connected.  It sounds like your stick is autodetecting output mode not input.

Yeah, maybe it's just the pics, but it almost looks like the black wire from the U360 harness is chopped off. Where's that going?

The black cable goes from the harness to the COM on the top right switch, which is button 1 (hence the brown cable) - I cut it with a view to putting
it on the red button before I remembered I wanted to run buttons 1-3 on the top row rather than the bottom!

Do you think there's trauma on the COM cable connection on the harness then? I'll take another photo just of that when I get home so we can see but it would certainly account for everything (ie not even button 1 working).

Any other thoughts please guys?

I can daisy chain to the COM cable on the other harness can't I? Just thinking, otherwise I'll have to recable all those switches again (not to mention buying another harness). Cheers

Piecesof8/BobA - Guys bang on!! I went to take a photo of where the COM cable was going and it was indeed snapped off the COM terminal of button 1. Where you said "looks like the black wire from the U360 harness is chopped off" I thought you meant harness end not terminal end! I have now re-stripped and re-crimped the terminal on button 1 and all 8 buttons are responding.

Cheers guys!!!

I've found that doubling up the wire from the harness when I crimp it into the quick disconnects (stripping about double what you need and then folding it over before you slip it into the qd) helps it get a better connection - it's a pretty thin gauge of wire and seems to like to slip out. Glad you got it working!
