Cube+ Orange SPKT port help

Hi all,

I am having some issues manually controlling my aircraft with a transmitter connected to Cube+ Orange.

The Cube+ can control the servos fine and my Spektrum AR637TA receiver connects to my TX16S transmitter just fine.

However, I have no feedback when I attempt to input manual commands from my TX16S. Mission planner does not show any radio inputs on the ‘radio calibration’ page.

I have tried using the smart port on the Spektrum receiver to the ‘RC in’ and from some looking around online it seems it won’t work and needs to be connected to the SPKT port (JST ZH).

If I do NEED to use the SPKT port, how do I connect it to my the receiver?
