not enough ports on ipac2? PLEASE HELP

(1/4) > >>

Jeromebechaz:
i haven't found the answer to this question anywhere yet, hopefully you can help me.


when i make my controll panel i want 6 additional buttons (pause, esc, setup, enter and 2 pinball side buttons.

i know that there are 2 ports o each side of the ipac labelled 1a and 1b i think, do they go in there and does it matter which side they plug into?

now for the 2 pinball buttons, do you just plug them into any regular button port? so they will work, but the button that is also in that port will work it to?
this may sound confusing so im sorry.

Drnick:
Cannot answer the 1a/1b part, But as for the pinball buttons, yes just wire them up to same connections as normal buttons.  You can put a switch in to disconnect ground to these buttons so that they are normally not live if you wish.

surface tension:
1a and 1b you can just program like any other inputs. The ipac is flexible, so it doesn't really matter where anything goes (apart from 0v). It's labelled for ease of use and default settings. The IPAC has four generically named inputs 1a, 1b, 2a and 2b.

Jeromebechaz:
thanks heaps for your help i understand it now :)
1 more question, does it matter where the ground wires go to? what are they for? i know every button goes to ground, but what about wires like the pinball buttons? does it matter?
or do you o a loop with the daisy chain, so say you start the daisy at p1 ground terminal, take it to every single button and end it at p2 ground?

kahlid74:
There is no P1 or P2 ground, they are all just ground.  Any button/switch that you would plug into the iPAC needs to ground INTO the iPAC otherwise it won't work.  The only way the iPAC knows a button/switch is pressed is when it sees the current traveling from one of the connects back to the ground.

So yes, you can daisy chain anyway you like, as long as it daisy chains back to one of the grounds.  Don't forget also that when you daisy chain, if the chain breaks, many of your buttons can become unresponsive.  Daisy chaining is the way to go but you need to make sure your chain is secure and fully connected.
