D9200 pinout for Sega Blast City

[Kidkaos]

Hello, I need to mount my D9200 into my Blast City.

I am not able to get a picture at 15khz no matter what combination I have my wires on the connector

Does anyone know how it's supposed to hook up for sync??

I get a good picture with VGA.
I moved the little connector to cga/ega and I get no sync at 15khz

No need to switch the connector. It will sync 15k/24k/31k/37k from the Dsub connector.

If you are hitting 31k but not 15k I would guess there is something wrong with your 15k source?

After further testing I got the monitor to display 15khz on the Naomi with the Naomi dip switches set to 15k, BUT the chassis will shut down and turn back on like every 2 minutes? Not sure why, it doesn't do it at 31khz. I'm not sure why that is needless to say, I need the pin pin out for 15khz through the jamma edge.

Looks like the remote board connector header position needs to change depending on 15khz vs. 31khz. Page 3 of the attached manual. https://www.arcade-museum.com/manuals-monitors/Wells-Gardner-27d9200-33d9200.pdf
