V6 II TX's to both of my V6 RX's with any group selected?

My new V6 II (firmware updated)  transmits to my two(2) original V6 (firmware updated) receivers when any of the groups are selected, rather than the group the receiver is set too?  

Any Ideas?


  • I've now updated the V6 II with today's firmware update, and now the Rx's trigger when none (0) of the 4 groups are selected, so you cant ever turn off any groups (on the older V6 Rx's) from the new V6 II.  

  • You need to wait for new firmware on the original V6, which we will release next month.

    Then you can remote power control flash mounted on the V6 from a V6 II (TX).
    It will support Power Sync (power boost) at above x-sync.
    But it will not suppoer Normal HSS.

    Thank you!

    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", "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) and not by X-TTL firmware versions: PEN.A.001 and OLY.A.001.  No schedule has been released yet. 

    Cactus RF60X / RF60 Firmware versions A01 and A02 currently ONLY works with PEN.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.

    Cactus RF60 is now an off-camera TTL flash with firmware version 205 or later!

    Metz M400 (for Fujifilm) is now supported on the Cactus V6 II (HSS and TTL).
