2L12B Japanese CP to this I/O board wiring harness needed

OldFoo · Post by **OldFoo** » Sun Jun 07, 2009 11:49 pm

Dear folks, I don't know what I need nor where to get it. I can't seem to ask the right questions. Here's a photo of the I/O board, and a photo of the control panel. Sorry about the quality of the photos. The cab is a US Naomi Universal (and the sucker weighed like 300 lbs, I think!), and I think the parts are straight Sega. The wires need to be around 3-4 feet long.

I/O board:

Control panel:

Any help would be appreciated. I'm lost

I could be wrong as I use different IO than that one...but I'm thinking the control panel would wire in to the plug on the right side of IO looking at the pic you posted...I'm thinking it's a JVS IO as opposed to a jamma one...there should be a pinout for that around these parts somewhere which would tell you generally what wire goes where...but again, take that with a grain of salt as I'm not entirely sure....anyhoo hope that helps...

I'll check that this evening - where would the identifiers be that would establish which I/O it is?

generally you can tell just by visual inspection...the JVS and JAMMA IOs look different enough to eyeball it.

It is JVS - do you know where to get a wiring extension for it? I need it to go around 1.5m, or 4 feet. sigh...

If you cannot find the correct loom, rewiring is a good alternative.

What cab is this? Since the JVS IO is populated, I guess there currently are connectors in your cab connecting the old control panel?

If yes, photos please

Yes, there are old connectors. They do me no good, however; the old CP didn't come with the cab, for whatever reason, and it was a World Series CP. Here are the connectors.

yeah, you've got a US cab and a JP panel.

I hate that they used molex connectors in the US cabs, your CP seems to have the usual 1p and 2p AMP connectors, plus the extra button one, though it appears to end in a Capcom extra button harness which is cool.

I think this person had the same trouble...

You could get molex connectors for the ends of the harness you have, add wired and then get the other side of the amp connectors for your CP and bridge them wire by wire. Would be a pain, but the result would be good and you could then plug any Naomi CP into your cab just add or remove the adapter. Just a thought...

another thought, does anyone know if the CP that was on this would have been analog or not? if so my adapter idea above wouldn't work.

There are two big connectors on your IO board, the shorter one is for analog (beside the USB) and the one closer to the Naomi 2 mobo should be the digital one. In the link I put in above there is a link for the pin out on your IO.

Good luck!

The other problem is that the US cabs like your appears to be have the IO down with the mobo, but the JP style ones have it right at the CP, so the harnesses you buy may be the wrong length.

If this is wired for World Series, then yes. The baseball bats on the CP are analog.

Wiring diagrams for the world series 99 CP are here: http://www.segaarcade.com/pdfs/worldser ... agrams.pdf and here: http://www.segaarcade.com/pdfs/worldser ... grams2.pdf

For World series 01, I think it is the same. The KIT manual is here: http://www.segaarcade.com/pdfs/worldser ... manual.pdf

Enough info to satisfy your soldering needs, me think
