Decklink Duo 2 Mini connectors?

I have a question that I hope someone can verify for me, I'm going to try and buy one or two of the Decklink Duo 2 Mini cards https://www.blackmagicdesign.com/produc ... s/W-DLK-37 for work, and want to make sure I buy the correct adapters... Is it:

HD BNC
Mini BNC
DIN

I've seen Mini BNC listed but wanted to make certain before I request the purchase. I'm planning on having it around for emergency backup if our studio CG fails, or studio video playback server fails (for CasparCG or New Blue Titler Live) or for OBS or maybe Wirecast if I can shake more money out of the tree. Yes I do need the low profile card and bracket, I know it does not come with with the full height bracket, we have HP Z240 SFF for video work.

HD BNC cables I can make, we have a bunch of DA cards that use these, but I don't have tools for Mini BNC or DIN connectors, and don't stock the connectors. I can probably buy some Mini BNC connectors for the cable I stock, can't be too much different from the HD BNC or "regular" BNC for strip length and I should have a crimp die for them.

Thanks in advance for any help that is offered.

They are DIN.

Thanks, appreciate that.
