Adjusting HW-Wheel - Expo and DZ

I’m sorting out the calibration and adjustments to the hardware controls on the HereLink.

I have my AirLink Ground Unit connected to the Air Unite - which is connected via S-Bus to an Orange Cube.

I have the Orange Cube connected to Mission Planner - and I’m monitoring the PWM signals on each channel on the SETUP/RADIO-CALIBRATION page.

I’d like to make the Control Wheel make slower changes to the PWM values.

I tried changing the EXPO and DZ settings - and this did not appear to change the PWM output the Hardware Wheel channel.

Is there a way to slow the rate of change of PWM output for the Hardware Wheel?
