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", "FUJ.1.002", "NIK.A.001", "v.103".

    For the time being, Cactus V6 (MK1) running on firmware version 2.1.001 can be triggered by a V6 II (MK2) running on Multi-brand HSS firmware (e.g. 1.1.013) but not by X-TTL firmware versions:  PEN.A.001 NIK.A.001 OLY.A.001.  No schedule has been released yet for an "A" version firmware on the V6 (MK1). 

    Cactus RF60X / RF60 Firmware versions A04 and A03 currently ONLY works with PEN.A.001 NIK.A.001 and OLY.A.001.  Other "A" version of X-TTL firmware will be released soon. For both Multi-brand HSS and X-TTL firmware versions (FUJ, SIG, SON), install firmware version 103 / 205 on your RF60X / RF60.
