Fuji XT-10 and Nikon SB900 won't fire

First time using new V5 duo - attempted to follow all instructions that came with units but unable to get fuji to fire the flash either on the V5 on camera, or the Rx V5 off-camera.  Many thanks for some advice as to what I'm obviously doing wrong.


  • Hi @akennedy28,

    Have you already set the SB900 to M (manual) mode.

    As for the V5, make sure both transceivers are set to the same channel.  You can half-press the Test button on the TX unit and see if both unit lights up.  Keep them at a distance and not right next to one another.

    To help us better help you, always state the exact firmware version installed on your Cactus device(s), such as: "1.1.013", "NIK.A.001", "v.103", or "A06".

    TTL or HSS not working on Cactus V6 II and V6 IIs? Be sure to check hot shoe connectivity by doing the <CAMERA INFO> check.
