Herelink Setup Error

I have a quick question, I’m having an issue using the herelink system, more specifically the herelink air unit. I continue to get an error on mission planner saying “No RC Receiver” when all components are connected properly. I’m not sure if it has something to do with mission planner config or herelink config. The herelink controller unit is bound to the receiver and can conduct manual motor spin testing on both the ground station and herelink controller. I am unable to arm as well.

Any suggestions or sources help, thank you

Check you have the correct S-bus lead pluged into the flight controller then all should work
