A subwoofer doesn't work on Master comms, only Slave comms, so AC200 to Subwoofer won't work.
The DSP3200 must be in the system so one can become a Master.

Can you describe precisely how you have then connected a SpeakerLink output from a DSP3200 to the AC12, and the cabling from AC12 to subwoofer?
Which sockets did you use on the AC12?
