RE: Aurora 9Ch, Spectra Pro & Optima - FAQ & Undocumented Features - Mixes, Setups, Tips.
As per Bob, to make the A9 work with AFPD, create a ACRO model in the A9, remove the module, power it up (it doesn't power up automatically with the trainer port plugged in), plug the usb cable in (no adapter needed) and calibrate in AFPD.
