Use the x-sync port for connecting external devices for activating the trigger.

I want to use my V6 triggers for high speed purposes. 
Therefore I have an idea to use a V6 trigger as interface for several different kind of devices which should activate the trigger.
Can I connect devices on the X-sync port to activate the trigger?
Could you provide me some info (datasheet) concerning the x sync port? 


  • Have more or less the same question. I can use the sync port to trigger flashes from my flash meter. But I would like to use a timer to trigger BULB exposures. So I would need to convert from the 2.5mm stereo plug of my remote release and timer to that 3.5 plug. I tried a stereo 2.5 to 3.5 adapter but it doesn't work.
  • @HvD, yes you can device to the X-sync port of the V6 set to TX mode by using a 3.5 cable such as this one:

    @bwing the Bulb Mode on the V6 requires the press and hold of the Test Button so unfortunately this cannot be done through the 3.5mm port.

    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).
