tongue switch for Nikon SLR

[sportshooter 0]

I'm trying to find out how to connect a Conceptus Tongue switch to a Nikon D2X camera. The camera uses the 10-pin MC-30 cable release. I've isolated the wires from the Nikon cable that trip the shutter, but when connected to the tongue switch I get either constant firing or none at all. Myself and 2 other guys who do tons of freefall photography couldn't figure the damn thing out. I've contacted Conceptus and they couldn't tell me anything other than to put a posting here. If you are using a D2X or D70S or D200 with a Conceptus Tongue switch and MC-30 cable please let me know the exact wire combinations you are using.

Thanks,

Darryl

the connection for the 200 is a three wire setup right?

one neutral (goes to the ring on the conceptus switch), second wire focuses and meters (goes to the center on the conceptus switch), then the third fires the shutter (goes to the tip on the conceptus switch).

you've got your options of colors and i'm not 100% that the colors are consistent from switch type to other types, but it's still a three wire right? so you shouldn't have much trouble figuring out the combination out of the 6 possible ways to do it.

a solution i've seen for a friend or two is... use the wiring pattern from the canon switch which is here. attach your MC-30 (or better yet MC-22 which i believe will work for you) leads to the appropriate poles on a 3/32" female connector. plug in the conceptus switch. put your camera in constant focus or run it in manual focus, put the shutter to constant. then you should constantly be focusing and metering whenever the camera is on and the switch is plugged in... then just fire the shutter whenever you like.

Yes, it's a 3-wire switch. What do you mean by the ring on the conceptus switch?

for lack of a better way to describe it it's the part closest to the wires on the stereo mini-plug type switches from conceptus.
