EV Adjustments not working Cactus v6 with Canon 430EXIII-RT

Dear all,

Recently I did by two cactus V6's. After installing and trying to use them I wanted to adjust the EV level remotely but the only adjustment I see is on the V6 RX and not on the flashgun. So no adjustments are made on the flash and I have to adjust the 430EXIII manually.

Both v6's have the profile of the canon profile for the 430II*

Hope their is a solution to this problem so I can use the V6's properly.

Thanks for replying.

Regards Arno


  • Hello Arno,

    If my memories are correct the 430exiii runs purely on digital TTL protocols so you need to select a flash profile that is also digital, such as the 320ex flash profile or the Godox V860 profile. Then set your flash to E-TTL mode and it will work.
