No FEL when using flash in pass-through on camera

in V6 II Problems
I have just received a couple V6 Mk2 triggers and am using them with my Canon 5D3 and 580ex flash units.

I am fireing the main light as on-camera, with the trigger set to pass-through.

All seems well except I do not seem to have FEL (Flash Exposure Lock).

Usually
I can operate FEL from a pre-designated button on my 5D3, and of course
the speedlight will flash whilst it is taking the reading - and then
fire at the appropriate power on my actual shot.

When I have the trigger between camera and flash, I cannot operate FEL as there is no test flash.

Is this a limitation of the system or am I doing something wrong?

    Hello @leethecam,

    Quick question, are you using firmware version 1.1.003?

    Our R&D is checking on this right now.

    Thanks!

    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.

    Hi Lee, I just replied your email.

    FEL is indeed not supported on the current firmware. R&D is looking into adding this on the next firmware release.

    The original V6’s TTL Pass Through is a hardware pass through, but on the V6 II, the actual pass through is done digitally. There’s a restriction as to the data size on the V6 II’s hardware so won’t be able to support all the camera / flash functions.

    We will probably not include functions such as bracketing as I think that’s rarely used in a multiple flash setup?  Others please feel free to suggest too.

    Thank you!
