I think you’re wrong. I think it’s the Kona2 card.
Running G5, dual 2.7, OSX 10.4.
Fostex D-10 (DAT deck)
Kona 2 RS422 plug will not control it; can’t even be seen.
Ran RS422 through my AJA I/O…worked perfectly. Then I routed my digital audio through the Knoa2 AES plug.
Therefore I had TC and control – RS422 – through the IO, audio through Kona 2.
Tried Kona 2 422 with JVC BR-HD50: wouldn’t work.
Please fix the drivers.
