MINI CONVERT ANALOG TO SDI HELP

Good morning,
I'have a mini dv camera, specifically : GY DV5000 from JVC.
I am trying to connect it to a regular sdi through an MINI CONVERT ANALOG TO SDI from blackmagic.
Looking in the manual i found out that the camera have a composit video from a single bnc connector output.
Connect this output through the Mini convert to an Atomos Shogun inferno dosen't work.
I think I setup the convert right following the info in the back for composite video.
The cable works fine, the output from the camera works.
Where i did wrong?
Pls help me.
