z-680 control pad for z-2300?

[sabbathcrazy]

I am not sure if this is the right place for this thread. Please move it to the best area.

I saw a add on Craigslist for a Z-2300 sub woofer. It does not have the control pad. I have some old Z-680 speakers sitting around (no amp) so I wanted to buy the z-2300 sub and use the z-680 speakers and control pod with the z-2300 amp and sub. The z-2300 and the z-680 use the same 15 pin cable.

I found this site witch can tell me witch pin does what for the z-2300

I need help finding out what pin does what for the z-680
So I opened the z-680 control pod up and looked at where the 15pin wire was connected to the circuit board . I need some help identifying what they mean and witch ping its connected to.

I doubt you will be able to use a Logitech z-680 control pod (digital) on the Logitech z-2300 system (analog).
