Atem Sdi Pro Iso / input interlaced signals

HI
We installed the mixer but found that it "doesn't see" the interlaced formats (i50 and/or i60) being input, even though these are listed in the stated specifications.
Where do we go wrong?
Suggestions?
Thanks

It must work .. I was used it with 1080i50 on input and everything was fine ..

The switchers are progressive.

Anything sent interlaced will be converted to whatever frame rate the switcher is set to.

So if you set the switcher to 50p and send it a 50i or 50PsF signal the ATEM will convert the 50i to 50p automagically.

You cannot get interlaced out of an ATEM Mini/SDI.

An strange behavior that I found;
Cameras in 1080 i 59.94
Atem in 1080 P 60

The conversion result in visible 30 fps

But, if I set cameras in 720 P 60, I get back the 60 fps...
