You are looking for one of these:

These are supposed to come with the system, but if someone misplaced or threw it away... :smt012

so far for me its been one of the hardest parts to track down. you may have to make one yourself. thats the best bet.

Thank you very much guys!!!

i got another couple of questions...

Is this correct for the voltage?

orange +12

red +5

black GND

and...last one...

if i want to plug a capcom converter with the sys 246 can i use this adapter

or i need another one with different wires layout?

Again...Thanx in advance to everyone!!

Your wiring identification is correct. The Capcom I/O is connected the same way, so no adapting is needed. However, I'm not sure if the 246 will work with it. :smt017

Hi!

These are easy to make.

The 246/256 will work with the capcom IO and a special cable except...

WARNING WARNING WARNING WARNING WARNING

If you have an after-market or aging DVD drive in your 246, it will draw more power than usual, which I would *assume* can fry a Capcom IO.

The extra power draw of after-market DVD drives will *DEFINITELY* fry a Namco JVS IO (the standard one that comes with the 246).

WARNING WARNING WARNING WARNING WARNING

So after all those warnings... you can easily run the DVD drive power off of a JVS power supply (it has a normal PC 4 pin power connector) so that it's power draw isn't going through the JVS power connector. YMMV, IMHO, it's an extra step that's definitely worth taking.
