Origin of Nanao MS9 with Degauss Relay, 5-pin Molex connector

[NFGx]

Update: solved! See this post.

I picked up a spare MS9 last year and I'm just now getting to looking at it more closely, and maybe installing it somewhere.

But it's a weird one, with a VGA connector, a Molex 5-pin for power and degauss, another connector for the chassis PCB that none of my other MS9 units have, and a relay on the input panel.

The internet being what it is these days, I'm having no luck at all finding information on this. Yaton sells the same input panel with all the wires, but doesn't make any mention of where it's from. That guy with the cables on ebay has the connector and harness that match mine, but of course there's no mention of what the pinout is, what it does, or anything more useful than 'Konami' as a somewhat unhelpful clue.

So I've spent some time trying to figure it out and I am pretty sure the pinout is AC / AC / GND / DGauss / DGauss.

But what's the relay for? What's the extra connector on the chassis for? What's this monitor from?

And what search terms should I be using 'cause I've been on this for an hour and I got just about -nothing-.

I’ve been wondering this too. I know some time crisis 2s had this version

Yeah, I was going to say looks like something out of a Namco cab, not Konami.

As for the connector and relay, no idea. Try asking on Arcade-Otaku. I'm sure PrincessPrinPrin would know.

I can confirm that the 2 x Jap built Time Crisis 2 I’ve had used this chassis type

I talked to the person who sold it to me, and apparently it's from a Namco Final Furlong 2.

But I can't find a Final Furlong 2 manual, just a conversion manual for FF1->2, and the FF1 manual has a schematic that doesn't match this one.

I tried looking at Time Crisis/2 manuals but they don't have matching schematics either.

By the way you phrased that, I guess you don't have it still?

could it be for the "NamCam" camera?!

?

Final Furlong looks like this:

It doesn't have NamCam.

Also, NamCam never has it's own screen. The pictures it takes are displayed in-game, on the main screen.

from the mame source:

Notes:
This board controls the video overlay from the CCD camera in Gunmen Wars, Race ON! and Final Furlong 2.

 

[nem]

That may be, but as you can see from the cabinet, there is no camera. Maybe a feature that was planned, but left out? Or maybe the board serves a different purpose in Final Furlong.

 

[NFGx]

In any case, the camera overlay is handled very differently, the camera import board is part of the game PCB stack and the overlay is done in software. It's not handled by the degauss pins. =)

I think I found some detail in one of the many Time Crisis 2 manuals I've found (this one from files.arcadeinfo.de. There are a few variations of this game, the European version is definitely different to the US release. This PDF is definitely one of the top-5 worst PDFs I've ever had the misfortune to need, but it seems to show the 5-pin connector on the monitor, and my guess at the pinout was more or less correct. One of the degauss pins is GND which is not normal, so that's good to know.

The other one, pin 4 (Degauss, White/Yellow) goes to the degauss switch. But the other side of that degauss switch runs off into the cab somewhere I can't follow.

I'm wondering now if the two degauss buttons are simply triggering the degauss circuit in both CRTs at the same time, which might explain the need for a relay. Still doesn't tell me what the other side of the degauss switch is connected to though.

In this image, the four lines from the two degauss switches are heading from the switches on the right, into the great photocopy void. After that... It's not clear to me.

I kept the 100V, and sold the 240V to @mR_CaESaR .

We both still have them.

Mine is not easily accessible at present, but I do need to pull the chassis for proactive service soon, so if you’re not in a rush I can likely get you the pics or info you need then.

 

[NFGx]

I heard back from the person who sold it to me. They sent a couple of photos of the wiring diagrams, and it turns out... It's just a normal switch, after all.

I have no idea why it's more complicated than normal on the monitor end.

 

[trashedcabs]

The degauss button on the MS9 directly passes 120v AC with a reasonably high current through the button itself to the coil for a short time. The relay is likely there as a safety improvement so the button is a simple low voltage switch to toggle the relay.

 

[NFGx]

Near as I can tell, this is the matching part for this connector:

Universal Mate-n-Lock 1-480763-0

Now to wire up a sega-compatible input.

The degauss button on the MS9 directly passes 120v AC with a reasonably high current through the button itself to the coil for a short time.

That's hugely surprising to me. There's often an audible click from the chassis when degauss is done, I assumed there was always a relay on board somewhere. That the AC power runs through the switch itself is... Well it seems unwise.

 

[NFGx]

Yeah, so, in news that makes me feel like a bit of an idiot, I was looking at the schematic for my Cyber Lead today, and ...

That fucker's got the same 5-pin connector in it as the mystery monitor I was trying to identify. It's definitely a Namco thing, if only I'd known that (and thought to look - it's right there FFS). Says right on there that it's a Mate-n-Lock too.

I should pull the back off and see if the chassis uses the same relay system.
