If you wanna use any PTHD version above HD10.3 10 you need a HD Pcie or Tbolt box or a HDX card.

All TDM cards are done with from HD11.0.0 and onwards (64bit) so you cant ise them to run HD12.5 and need one of the three options i posted.

You can still use the 192 interfaces with the new options but you do need a HDN or HDX card/tbolt box.
