CMUcam3 and Roobnova

Hello.
I’m trying to connect cmucam3 to robonova via camera servo outputs. Since cam can operate with standard servo, so it must behave as a rc receiver, am i wrong?
So using RCIN command on any AD port on nova i could read position, that cam sends to servo.
I’ve tried this, have no effect, i received nothing or crap. I’ve tried to use servo outputs as gpio (digital output), had no result again.
I’ve modified camera code - put signal output in cycle (i.e. for i=1 to 1000 do sendsignal) - now, if i send i.e. “150”, i see on nova LCD something like this number, but for supershort() period of time, just enough to fighure out it’s something about 100.
I’ve tried to connect hsr-8498 servo to camera - operate just great.
Tried to send positon to servo throught nova without printing value, just read it and move servo - servo allways move to max position of one side.
If anybody have a deal with this issue, or have any ideas - you welcome!
