I have the RS 3 Pro with the Lidar Range Finder. It all works on with auto focus and active tracking. However, when I have it transmitted to the DJI High-Bright Remote Monitor, and with the hand grips controllers, it seems I can't control from the monitor (focus, or gimbal movements), because that connection port on the gimbal is taken up by the Lidar Range Finder. Am I right to say I can't have both at the same time? Which means, if I am using Lidar Range Finder, I can only use the monitor to view, the hand grips controllers will be useless, and vice versa? But then I also see an option on the monitor that says "Lidar waveform", so maybe the two can work together same time?

Have you tried the second USB of the focus motor? Maybe one or the other could be connected tere///.
