Hello,
Im using a decklink duo 2 which worked great with my 80m 3g-sdi cables but suddenly i get no signal using these 80m cables. when i use a 5 meter cable everything works fine.
i tried the 80m cables with my atomos shogun and the signal is pefect using the 80m cable, any idea why it stopped working with the BM decklink duo 2 ? I updated to 10.9.5 etc.
what for is the usb plug on the card?

any ideas?

thanks
felix

Anyone?

Which cable do you use? 80 metres is very long for 3g sdi! I once had about 100 metres sdi, 720p50, every time i used my radio set, i lost my sdi signal...

lots of different cables have different ratings on distance depending on the signal and size of cable. a typical RG6 cable should go 100m.

What could be is that they changed some code for controlling the Cable EQ / Reclockers on the Decklink card..
But that is if you are very certain that the firmware update changed this!! But it could also be a lot of things like Payload packet in 3G.
