C02/D01 IO RJ45 to DIN8 connector pinout

This was created by using the BIO2 sub IO board to connect pre IIDX 25 cabinet hardware to the BIO2 IO board. The two connector types from different generation IO boards, RJ45 on the C02 IO board and a round DIN8 connector on the USBIO2 board are just different connectors to the same hardware on the BIO2 sub IO board.

Therefore, any C02/D01 wired cabinet can be upgraded to IO2 wiring and vice versa by building a RJ45 -> DIN8 or DIN8 -> RJ45 adapter cable.

The following connection information was traced on a original Konami BIO2 sub IO board.
