Hello,

Last night my Capcom IO gave me a scare by not getting recognized by the Naomi after several tries. I fixed it by cleaning the jamma connector but I also checked voltages and noticed I have it set for 5.2 volts (at the jamma connector).

I think I read it should be set to 5.1, so what do you guys recommend?

I swap boards a lot on my cab, cps2, cps3, Naomi, etc, so I'm looking for the best overal voltage setting.

Thanks.
 
Shouldn't it be 5v? That's what mine runs at. As a side note, power your naomi separately unless you are only using cart.
 
Aye, start at 5.0v no load and increase to 5v when connected. Capcom I/O can be a power hog so remember to adjust voltage back down when switching back to another PCB.

I just recapped one and I had to increase .2v from 5v no load.
 
Ok, thank you all. I'll dial it down a bit and work my way up if needed.
