Cube black on Kore Carrier Board sbus out

I have the cube black on Kore Carrier Board and I want to get sbus out for my camera
I tried to config it and I don`t get anything from the sbus out port on the Kore Carrier Board.
I followed this guide:

any help?


The Sbus out port on Kore is a mirror of RCIN which convert its signal into sbus.

The setup from the link is to enable output signal from PWM out.
