Cactus V6 II does not work with cactus V5 as transmiter (or reciever)

My new Cactus V6 II (with firmware update) in transmitter mode is not recognize by the Cactus V5 at recieve mode. I have tried many channels... no change. Does somebody have an idee of the problem ?


  • The X-TTL firmware variants are not compatible with the V5 anymore.

    You need to select a V6II firmware version starting with "1.". I think all of them are still compatible with the V5, but potentially you even need to check the release notes to see if you need to go back to a certain older firmware version.
