Herelink S.bus issue

I have experienced an issue with Herelink that the S bus out is not working at all. Have tried firmware update as well as factory reset. Anyone else has the same issue? On a DSO it shows some really strange waveform unlike PPM. Issue with both the Sbus outs

Have you finished the hardware calibration?

yes. All show up on software correctly but do not give an output

Can you show the waveform pattern from DSO?
Also, can you show the connection between air unit and autopilot?
