Having a RS4 Pro and Focus Pro with two motors I can't get both motors to work with one for focus and one for iris on a cine lens.
I was hoping that the joystick control switch would give my 2nd motor iris control but nothing seems to work.
How can I configure this option for two motors?  Seems like it should be available in this Ronin ecosystem.

Hello, there. You may check the information below and see whether your setup is right:
DJI RS 4 Pro supports controlling up to two focus motors.
When dual-focus motors are installed, the motor can be controlled by the front dial. Make sure “Dial Functions” is set to “Focus Motor” and the Joystick Mode Switch is toggled to Zoom. At this point, both focus motors can be controlled for focus and zoom.
When the focus motor controlled by the joystick is connected to the lens aperture ring, the lens aperture can also be controlled. In this case, no additional settings are required for the joystick.

I think that the only option is to treat motor connected to iris as a zoom or focus motor.

As far as I understand RS4 Pro can control two motors: focus motor (by wheel above trigger) and zoom motor (by joystick), so that's what needs to be set on the motor itself (correct led lit). What ring they are connected to doesn't need to match what they are viewed by RS4 as.

Thank you for the helpful replies, that makes sense.
