how are y'all hooking up DC with IPAC?
<< < (3/6) > >>
radiator:
Tom, just got yer email

it works perfectly, mine is wired as follows:

Controls ~ IPAC ~ Diode ~ DC Pad
(~ = wire)

just make sure you have the positive end of the diode facing AWAY from the pad (ie, negative goes to pad)

one diode per input

i've not tried having both the PC and the DC on at the same time, but who'd do this anyway?!
you don't need switches or anything, just turn on whichever system you want to play, and Bob's yer uncle

if you still require any more help, then don't hesistate to email me!
 ;D

EDIT:

ooh, and ground doesn't need a diode, you only need 11 diodes per pad (up, down, left, right, start, a, b, x, y, l, r)
Frostillicus:
Excellent! Thanks radiator and crashdmj for your help!

It's not clear to me why the cheaper Lik-Sang convertors are not suitable. Can someone explain?

Thanks

We're trying to connect arcade controls to both an IPAC (which interfaces with the PC) and a hacked Dreamcast controller (so we can also play Dreamcast games)

I think you're thinking we're simply trying to interface a DC pad with a PC, which isn't what we're doing...
Jedi Master Matt:
I think I'm up for taking the diode challenge; but, I've got a question.

I'm using P360s, so I need to get power to them.  Right now, I've got the +5v coming from the USB Opti-pac instead of the USB Ipac.  (I was anticipating this senario).  So, turning off the PC will cause me to lose power to the joysticks.

So here's the question...

If I leave the power coming off the Opti to the joysticks AND leave the PC on and simply unplug the IPAC, then turn on the Dreamcast, should this work?  Do you think there will be a voltage/ground problem?

(b.t.w.  thanks to everyone here... I've got my CP working and have spent the last week playing games like crazy.)
