Promedia 2.1 v1 Sub, v2 Control Pod, Adapting Pins

[MaringUpAudio]

I recently got a thrift store Promedia 2.1 v1 Sub, and v2 Control pod. So in order to connect the 6 pin DIN and the DB9 I've looked into what the pins carry. It seems like the DIN only carries LPod, RPod, Sub, -V, +V, and NC. The v2 Control pod I believe doesn't use all of the pins, or that some of the pins can be ommitted to allow for using it with the v1 Sub. Has anyone tried using a standard PS/2 to DB9 adapter, or knows where to find one that will tell you how they mapped the pins for the adapter? I'm hoping to be able to use that rather than having to go through a solder my own connections.
