Hi

Just got the new LB2. I'm trying now since hours to get a video signal on the screen but the red led on the LB2 air unit never switch to green. I'm using the S1000+ with the A2 controller and the new ZENMUSE Z15-A7. I've also set the HDMI output at the camera on 1080i but it still doesn't work. I really have no idea what to do. Does anyone know what it could be?

Thank you so much for your help!

It is normal that the video of LB2 is red when using HD gimbal. Make sure the both LB2 and GCU are connected to CAN 2 of A2,  and the FC and gimbal GCU are up to date.
Pls use an Android phone to change the output to EXT mode, and set the bandwidth allocation to let the EXT owns at least 50% of the bandwidth

I got the same problem, I have not tried to connect the CAN cable through a HUB yet, I am using a CAN port at the iOSD, that could be the problem.
If I connect to the HDMI In port (FPV cam) I get picture, but not through the gimbal Z15-GH4? And , yes, I have tried to switch between LB-EXT-PIP_LB and PIP_EXT, no picture.
A CAN HUB is on it´s way, get back when I tried with that.

Hi Everybody!!

I had the same problem with same configuration:

S1000+ with A2 + LB2 (And also a futaba 14sg) + Z15 with a A7-HD and a SOny A7s camera.

First time, I havent video signal, but I config on DJI Go  app output mode to EXT and separate minimun 5 meters from LB2 air station (my drone) and I recieved perfectly video signal!!!

Thanks!!

I have an S800 Evo and gimbal carrying my a6500 - this thread helped me find that I needed to switch the camera's HDMI output to 1080i instead of 1080p so thanks!
