ARRI Forum

I recently setup a OCU-1 to adjust focus on an Alexa Mini using a CForce Mini motor. Every time I powered on the camera the OCU-1 would not allow for the control of the CForce motor, then I would unplug the OCU-1 and plug back and then the OCU-1 would control the motor. When powering on the camera the OCU-1 screen came up and would allow me to calibrate the motor but no mater what it wouldn't control the motor until I unplugged it and plugged it back up. Is this an issue that anyone has had before? Is there a firmware update to fix it? I was not using a WCU-4, my setup was to use the OCU-1 on the handle of a handheld rig. CForce Mini motor plugged into the LBUS port on the Alexa Mini PL mount and then the OCU-1 was plugged into the motor.
