I have finally gotten all the pieces to get my Thumbwheel to control the DJI Focus Motor..
I am running a Ronin-M and have the P-tap power cable for the motor with the little communication cable for the port next to the P-tap port..
I do not have the DJI Focus remote handwheel for second operater, because I just need to run solo..
However after connecting everything and updating all firmware the system is not working..?
I have a green light on the thumbwheel, and the light on the motor is continuously on which should indicate connection, but the system is not responding..
Please help..!!!

Have you tried pressing the lens and direction buttons simultaneously?
