Osee Mega 22s4 -no video on loop out

i have a few Osee mega 22s4 getting 23.98/1080p signal through SDI into input 1 from an alexa 35. the signal displays fine on all my monitors but i cant seem to get any video out of Osee's OUT port to daisy chan the image.

the same signal passes loop out on my flanders dm220.

i cant seem to find any menu setting regarding enabling the sdi output on the monitor. any ideas? is this port not a loop out?
there are no other signals going into the monitor. just the single cable.
im on firmware 11.02
