IO2 Shutter out signal while recording only, is that possible?

[clkdiv]

Hello,

I need the Shutter signal of the camera to sync some external gear to the camera, but the sync shall only run while the camera records. As far as I can see the "shutter" signal runs all the time, also when NOT recording? Is there a way to achieve what I need? Thanks!

Do you trigger with an external Mechanical Switch or some kind output from any other device?
 In that case, i think i can come up with something, otherwise, i would not know how to do that.

Hey Nikon1! 

The camera will probably be triggered via IO2. I suppose I can also use BNC, if this helps... However my external device shall consume the shutter signal from the camera only in case only when it is recording.
Thanks! Martin

So if i understand correctly, this would be what you want? [Attachment]

Yes, exactly. I'd be happy to an in-camera-solution.

Hmmmm, I am trying to understand the IOConfig results that can be achieved via the Web-Frontend. The "Combinatorial block" seems promising. I can't test it right now, but from my understanding the configuration shown in the two images seems to do exactly what I need: Providing the "Timing IO" output only when the camera is recording. At least the red and blue triangles suggest that it does that.

If only "Timing IO" really is the Frame Sync Signal...

Very exciting...

[Nikon1]

that actually seems Promising.

Hello again. Just wanted to post my findings.

It is really possible to make the camera provide the "Timing IO"-Signal only when recording: Just setup the combinatorial block as described in the images above.

However if your are connecting the camera to an Arduino, you will have to set the "Drive Strength" to "High", if your are feeding the signal into one of the analog inputs.
