i bought last week Cactus Shutter Cable SC-N1 for Nikon D800, package arrived this morning great.
I own various Cactus v6 and i want to do this setup :

  1. First one is in my hand, relay mode to ON, TX Mode
  2. Second one is connected with my new official cable on my Nikon D800E, i mount it on the hotshoe. RX Mode.
  3. Last one is connected to an Nikon SB900 Flash. RX Mode.
  • All cactus are in group 1 / channel 1. 
  • I tested the configuration with short and long range.
well it don't work :-(
I tried various things :
  1. Autofocus seem to be good but when i press a little bit the button on Cactus. 
    But when i want to take the picture :
    - No flash, no trigger on D800e
    - RELAY TIME OUT message appear on D800e Cactus ??
  2. If i disconnect the flash it seems to be good for a simple camara trigger, with or without Relay Mode activated
Something is wrong on my configuration ?
Please helppp

    So you have relay mode ON on both your hand-held V6 Tx and the on-camera V6 Rx, correct?

    Relay mode must be OFF for all V6 Rx with flashes connected to them.

    When a "RELAY TIME OUT" message appears on the on-camera V6 Rx then this means the V6 Rx received the trigger command from your hand-held unit but then did not get a flash trigger command from your camera.

    It makes sense that this error message appears in your scenario, as your camera does not take a shot and hence won't create a flash trigger signal for the on-camera V6 Rx.

    The question is why the camera is not triggered in your scenario 1. but is triggered in your scenario 2.

    What flash are you disconnecting from where to make the triggering of the camera work in scenario 2.?

    Can you try to trigger the camera using relay modes for both V6 Tx and V6 Rx by not connecting anything to the camera but the relay V6 Rx via the shutter cable? Don't put the V6 Rx on the camera's hot-shoe yet. Is the camera triggered then?

    If so, can you add a flash (in manual mode) to the camera and see whether it is fired by the camera when you remote trigger with the V6 Tx?

    If it flashes then all that should be left to do is to replace the on-camera flash with the V6 Rx that is still connected to the camera with the shutter cable. Afterwards, you shouldn't get the time out error message anymore and your remote flashes should be triggered.

    BTW, for troubleshooting, it is best to put the camera into manual mode as well to create repeatable conditions. It may not be strictly necessary, but if you could use manual mode for the camera to ensure that it fires an on-camera flash every time, then it would be easier to just add remote triggering to that (and hence be one step away from making your scenario work).
  • Hello there
    thanks for your quick response.

    I did various tests and on my last try it work.
    Really it's strange. It is as if you have to follow a particular order to turn on/off the different devices...
    I'll try to clarify that, i will send you later my after-feedbak.

    Have a good day
  • ...Really it's strange. It is as if you have to follow a particular order to turn on/off the different devices...

    It is indeed true.

    We recommend powering your devices in a Top-Down approach:

    Portable Flash > V6 > Camera

    Please check if that helps?  Thanks!
