Yes, we will support FSK on BD-1000 (2nd generation) and BD-1750-PRO. Will not support on BD-1000 1st Generation.

BD-1000 2nd Generation = serial number starting in ZZ. Codename “zermatt”  
BD-1000 1st Generation = serial number starting in A or B. Codename “snowbird”

That said, QuietCool requires 2-way communication, which is not yet implemented and can only be supported on the BD-1750-PRO.
