LED BUTTONS

[Caparo8bit]

You need to add an ipac to your jpac to allow the inputs for players 3 and 4 along with adding all the buttons and joysticks to you panel.

i think im going to do the shift option...

I think he's trying to use the P3 and P4 harnesses for his buttons and not actually have a set up for 4 players. I think he's missing the basics of

1) You dont need to use the existing harnesses
2) All buttons share a common ground
3) You just need to run a wire from the terminals on the JPac to a button (and share a ground) for the button to work
4) Read before trying things
5) researching a little before asking what can be considered very easy questions that are easy to find answers to
6) 120v AC isnt the same as 12v DC

Thanks for the clarification Malenko.   I do not understand exactly what he is trying to accomplish with all the questions that do not seem to have a common goal.   I thought it would be a stretch trying to turn a 2 player panel into a 4 but I don't judge, I just try to provide info on the process.

Thanks Bob

Well sorry for my bad English there's no spanglish forums arround. What I'm trying to do is connect some of  the 3th or 4th player cable buttons in to the Jamma harness .can't connect more on j-Pac already using all terminals. In few words I'm trying to go from Jamma to j-Pac....

If you are already using all the extra terminals on the jpac for buttons you have to add another interface to add more buttons.   I now see you don't want player 3 and 4 to use just more buttons.  An additonal ipac or other keyboard interface would have to be added since all the jpac is used.

get a Molex (4 pin power 8189 series) splitter, put it in your computer, tap the yellow for 12v and the black for ground. Dont wire in the grounds with the buttons, its usually best for beginners to keep wiring sets isolated from one another.

[Malenko]

Daisy Chain.


You can run 2 wires (+12v and ground) from your power supply to your control panel, then splice/chain from there

[PL1]

Daisy Chain.

Not to be confused with Daisy Duck . . .


. . . or Daisy Duke.
