What are the functions and colors of the wires in the Nikon MC-DC2 Remote Release Cord? I need to set up a way for a Cognisys rail to fire the camera.

Thanks,

Jim

The MC-DC2 has shutter release and shutter release lock, The cable is black.

I’ve never chopped a Nikon cable so I can’t help with the direct question. But in triggering devices I’ve built I used the inexpensive camera specific cables from Vello etc to trigger the exposure, and a connection to a flash pc socket (or hot shoe) with the camera set to rear curtain sync to get an end of exposure signal.



All the lines in question are active low short-to-ground at low voltage.

The colors I'm looking for are the colors inside the cable. Which is ground, which is shutter release, which is half-press? Are contact closures to ground what actualts the function?

That's good. Now I just have to figure out which is which.

On the ubiquitous 2.5mm tip-ring-barrel connector of the trigger cables you short the ring to the barrel to wake the camera and the tip to the barrel to fire the shutter.

Some trigger devices treat that as one circuit with the tip and ring shorted together. On the Nikon bodies I've checked (D700, 800, 810 and Z7) there hasn't seemed to be a need to let a wakened camera settle before firing as long as you aren't metering or AF-ing. But it does seem necessary to activate the wake signal while you fire the shutter.

No color guide, but this pinout may be of some help:

A photograph is more than a bunch of pixels.

you short the ring to the barrel to wake the camera

On some cameras at least that is alike to a half-press on the shutter button, thus triggering exposure metering and AF. The other one fires the shutter, but does not trigger metering or AF.

For some reason, Nikon uses proprietary connectors.

Cognisys sells camera specific cables… maybe you don’t happen to have the right one on hand?

I’m uncertain about the connector on their end.

It does, indeed. Thanks.

Are you making some custom test equipment?

No, this is for real photography. Hard to believe, I know…

There are cables that adapt from Nikon's proprietary connector to standard 2.5mm trs connector, so that you wouldn't have to worry about what wire goes where. I use such cables with my Yongnuo wireless triggers.

Here's an example:
