About Aximmetry can't input UHD p50

Installation Studio Operators SDI

Hi everyone,
   We use Aja corvid44 12g BNC video card with Aximmetry. We found that output UHD p50 is work,but the signal from the Sony4300 camera cannot input to Aximmetry.Can you tell me how to setup in Aximmetry to enable the UHD 50p signal.By the way,we found that the same computer we install zero density it can enable the input signal.Looking forward to your reply!
