Hello I am new to the Pro System and recently I purchased a second hand custom made system with A2, LB2 and Z15.

What happens is as no camera was included I decided to leave the gimbo empty until I decide which camera/lens to use (potentially I may install other scanners including thermal imaging and a LiDAR etc). However, when I power it up the LED on A2 always shows Red even if I have checked the connections are correct.

I have binded the LB2 controller with the LB2, but A2 assistant doesn't show the connection between the controller and LB2. I wonder if the camera is essential for the drone operation?

Thanks for your advices.

Ivan, it has nothing to do with the camera, please double check if the D-Bus in LB2 is connected to the X2 port in the A2, then make sure you select the right RC Receiver Type in A2 Assistant.
