JVS I/O pinout clarification
Posted: Sat Nov 10, 2012 6:37 pm
I'm going to be wiring up a JVS I/O to a JAMMA fingerboard and wanted some clarification on what is actually needed to be connected. I have 2 NAOMI's but only one SEGA JAMMA adapter. I'm planning on plugging the I/O with fingerboard into the JAMMA harness of my Blast City for controls. This will free up the Sega JAMMA adapter for use in another cab.
My Blast didn't come with a '001' loom so I made my own power connectors and that's why I'm doing this the way I am.
I know I need +5v in on CN7 for the I/O to function but do I need to wire CN1 with 12v in as well, or is it optional?
Related to that question, are the +5 and +12 on the 60 pin digital connector voltage out? If so then I shouldn't need them unless I want to use 5v for spoofing coin counters, correct?
So what I'm thinking is that I need to wire +5 and some grounds from the fingerboard to CN7, along with all controls, test switch, grounds etc to the digital connector.
I will also connect a 5v line from the digital connector to the second coin counter at pin 50 with a 100ohm resistor inline to spoof a second coin counter.
Am I missing anything?
