Hi, friends.



I get 2 I/O type 837-13551 to my naomi board, I connect USB cable. I connect 5v input. When turn on the system 2 leds is lite. The system check to IO is ok. I need connect the commands input to buttons. I have a doc what have this input mapped, but the doc show linear 1 to 60 pins. The board conector is 1 to 30 x 2 colums!!!

Thanks I go make a test... The schematic is same another jamma?s board?



GND + 1UP = Player 1 UP

GND + Coin = Coin insert



In the doc 1p coin pin is GND+coin pin+5v!!!! 5v to what????



Thanks.

I'm not sure which diagram you are using, but coin insert is wired the same as any other jamma game.

If you want, the Universal Wiring Diagram is on the main Sega-Naomi website:

joshua,



This doc refers a JAMMA interface, pinout to 837-13551 is not same.

I upload my doc to you see...

diagram stay on page 35. See hook to coin pin!



regards.

Ah, I see. My mistake about the document. Just connect coin to switch input, ground to switch output

like standard connection. The 5v is for the coin lamp (L), which is optional, but not necessary.

Oh!!!! Great josh... is Lamp! I not recon this simbol....



Ok. I go test this pinout (with your instructions about pin sequence) and post results here ok?





thanks amigo.

Joshua,



I test and work ok. but in the map (doc) indicate coin as pin 45 !!! This not trust. Coin is on 37 and 38 think... but is working and this is the really important.



Thanks for you atention.

I looked a few different wiring diagrams with this type of I/O board, and all are the same. Pins 45 and 46 are for Coin 1 and 2.

Pins 37 and 38 (27-40) are for player buttons :smt115

I go check again... but 45 and 46 not working.... this is a fact!
