Test with Yongnuo-YN568EX off camera
HSS works ok
Zoom control does not work (Yes, Swap Control is selected under preferences)

Adjustment of Flash power. Negative (Dont work)

I really need a detailed instruction on how to use the Cactus V6II system.
Had expected everything to work fine with the Nikon SB-910 Flash.
However, I can not adjust Zoom from TX device.
In the case of Yongnuo Flash. Do I have to learn Cactus V6II to use this Flash ??

Yes, both flash are in Mode TTL

    On my Nikon SB-910 Flash I must go into the menu system and change two settings:
    1. Change from DX to FX ( not logical ?) I use a Nikon D500
    2. Turn manuel Zoom from ON to OFF
    When i do this I Can remote control Zoom on the OFF camera Flash ( Nikon SB-910)
    Still not able to use my Yongnuo YN-568EX as off camera. Flash.
