I managed to get the Anilam chief engineer on the phone one day not long after purchasing the BP and he walked me through the tuning process of the drives. I'll take a look to see if I have the same cards as you or not. For the drives part you need the analog velocity pins and the enable pin. On my cards to enable a drive you ground the enable. I tested mine with a 1.5v battery with the drive belt off...
