OK, but you can only get a 1080i output while the camera is set to 50/60/59.94fps not 29.94fps.
To set the Ursa Broadcast to record 1080i59.94 drop frame here are the Menu steps (This should also,work on the UM Pro):
First go to Record Menu, set your frame rate to 59.94, and select Video or Extended Video, then scroll left to Raw/ProRes/DNxHD menu, select DNxHD, and bit rate, I use the 145 setting, then the 1080i button will be active, select 1080i.
Next, Exit Menu, and check top line of heads up display on the camera monitor is set to 59.94i, if it shows 60i, then pull it down and change it to back to 59.94.
Third, Go back to menu, select Setup menu, on on the first Setup screen upper right is Drop Frame Off/On, select On
Now you are now in 1080i record mode at NTSC 59.94 with drop frame.
Both the Ursa Broadcast and the Ursa Mini Pro have the same OS/Menu system setup, so this should work to set your UM Pro camera to 1080i*. What I learned is you can not select 1080i, while in ProRes setting, only in DNxHD, which is the Avid codec most Broadcast stations use, or a NLE that can use this codec. You might check with the station about this first.
Edit: turns out the UMPro does not have DNxHD, so unable to record 1080i, only output it via the SDI .
