## C02/D01 IO RJ45 to DIN8 connector pinout

This was created by using the [BIO2 sub IO board](../io.md#bio2-ldj-sub-io) to connect pre IIDX 25 cabinet
hardware to the [BIO2 IO board](../io.md#bio2). The two connector types from different generation IO boards, RJ45
on the [C02 IO](#c02-io) board and a round DIN8 connector on the [USBIO2](../io.md#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.

The two connectors are interconnected on the PCB like this:
