iPac-2 SHIFT function not working
(1/4) > >>
axewater:
Hi everyone ..

Ok, 2 weeks ago I installed the iPac 2 in an old NeoGeo MVS cabinet, connected all the wiring and it was working fine. I could use the P1 start button as 'shift'. When pressed, the P1 Button1 became COIN1 and the P2 start would be ESCAPE (I think this is the default config).

Today I tried to get some of the buttons on the player 2 side cleaned out as they were sticking or not working at all. Connected 1 more wire and closed everything up again. From that moment on, the SHIFT function was gone.

Did some reading and apparantly the SHIFT function wont work if there is a stuck button .. Ok, ran various tools to see if there is a stuck button, there is NO button stuck according to this program : http://www.passmark.com/ftp/keytest.exe ..

Also the LED on the iPac2 is not flashing or turning off, which it should do if it detects a problem with wiring. It just stays lit.

When I run the WinIPAC software, I have tried reloading defaults and programming them into the iPac to no avail. Programming works but the SHIFT still doesn't work.

OS is Windows XP


ANY help would be appreciated .. I'm now using the external USB keyboard to insert coins and hit escape :(

I'd try disconnecting that one wire. Maybe it's not wired right?

In any event if the ipac light is showing an error, I'd expect all sorts of things to not work right.

It may be in opening things up, you bumped some wires and caused a short.

It's a pain, but you may need to disconnect all wires to the ipac except, say, a button, power up and verify that the ipac reports no problems.

then hook up, say, half the remaining wires and repeat, to try and narrow it down.

doesn't the fact that it stays lit mean there is NO error ?

all the wiring in the cab is still from 20 years ago .. so I guess it won't do any harm to replace the whole lot :)
end of the month I'll have some cash again and I'll order some parts. until then .. i'm gonna try what you suggest, disconnect all and reconnect a few at a time and see if i can get it working

on another note .. i just found out that the RIGHT joystick acts as a 4 way joystick (!!??) for some weird reason. But I will post that issue in a separate thread to keep things clear.

If you go into the I-PAC interactive test mode: http://www.ultimarc.com/interact.php this might reveal something.

I don't have a PS/2 keyboard here so I cannot try the manual program thingy :(
A friend is coming over next week with a PS2 keyboard, so I'll try that then.

In the meantime, I have disconnected all the wires from the iPac on the player 2 side but the problem still persists  :badmood: :badmood:

When I start WinIpac, what is the best way to check if the SHIFT function is working ? When I open the 'shifted function' page, am I supposed to see buttons working when I hit the combo ?

When I go to test mode :
if I hit the player 1 start, it shows '1'
if I hit just player 1 button 1 is shows 'L.CTRL'
now when I hold 1 start and hit P1 B1 it still just shows 'L.CTRL'

I will now disconnect everything except the P1 start and P1 B1 to see if I can get it working again .... I'll post my progress here ...
