Ipac/4 Not registering certain keypresses?!?!?!

<< < (2/3) > >>

hulkster:
as of right now, i have the same problem.  i have a 4 player panel with a trackball and all buttons work (including coin buttons and start buttons for all 4 players)....but the only buttons that dont register anything are the buttons that would be Pause and Escape.  i have them wired into the ipac at like, Player 3's SW5 and SW6.  why would all buttons work and not thse?  i replaced the microswitches on both thinking that might be it, but nothing happened.  do i need to rewire a disconnect?  or is this an ipac software thing.  i loaded the winipac utitility to test to see if everything was being registered, and it was for all the buttons and joystick movements, except for the pause and escape.  suggestions?

REBIRTH:
Just a thought, this is what I have done when I had a problem with the Ipac (problem was always MY fault).  

First, if you are using the WinIPAC to configure some of your buttons, make sure that is set up correctly.  It certainly sounds like you SHOULD be using this for what you want to do - configuring P1B7 to be Pause for example.  Normal P1B7 is NOT pause/escape/etc in Mame.  Pause for example is "SHIFT/P" - P1B7 is  a "C".  You would use WinIPAC to program your P1B7 button to equal the Pause keystroke in Mame - "SHIFT/P" (FYI - WinIPAC has all these Mame special buttons configured in it, you just tell it which button on your panel to associate with each Mame function).  Anyway, the original post sounds like you are using WinIPAC so my guess is you somehow have these buttons already configured to something else incorrectly?

Secondly, once you verify that is correct - if it still doesn't work in Mame - then in Windows upen up Wordpad or something like that and start hitting the buttons you are having trouble with and see if what is typed in Wordpad is correct.  So using the Mame pause example, you should see an Uppercase "P" in wordpad when hitting the P1B7 button that was configured with "shift/P" in WinIPAC.

Good luck - I think the IPAC and WinIPAC (free download) is ones set of primo products.  Assuming the thing is just not broken, I would assume you have something not set up correctly.

Tilzs:
Have the ipac do a dump of how all the inputs are programmed by entering test mode. Then open up notepad and see if your buttons output what it says they output

Grasshopper:


Hmm, this might not be related to your problem, but I vaguely remember reading in a very old thread that some of the standard (i.e. 2 player) Ipac's inputs are somehow shared with the keyboard LED connectors. Apparently these inputs can become unreliable if you connect your Ipac to your panel using DB25 cables or similar.

I've been meaning to email Ultimarc for some time to see whether this is a genuine problem as I'm planning a setup similar to yours.

Please can you post Andy's reply once you get it.

Thanks in advance.

AndyWarne:
Just to say I have noted this thread. I will assist by email as I can get hold of the relevant IPC and CPL files this way.
The LED input issue with very long multi-core cable is eliminated on later boards but this does not sound like the problem here.
