Black magic Decklink trouble

[Martin]

Or maybe the extreme card cable is designed to be plugged directly into a deck. so that its termination works?

Maybe - It doesnt work if you join it to another sdi cable coming from another piece of gear?

Black Magic told me that the Extreme is more sensitive to SDI than the Decklink standard, because the Extreme has the monster cable, while the Standard have the SDI connectors soldered directly onto the card.
