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.
