Hi all,

I finally found what I was looking for. Not need to hack it anymore.

The protocol is a little bit more complex than I expected, but still feasible to implement.

I'm developing a strobe with special features and this protocol may be a good adition in the future.

All the best, Alvaro

Yes they are trigger like flashes (short duration pulse ) the caps are regulars nikonos protectors caps.

Thanks and happy dives

Not much help unless you are a boffin but it seems that pins 2,3,4 & 5 are for digital serial communication with ETTL strobes rather than simple high/low status signals. They communicate stuff such as aperture, focal length, shutter speed. ISO etc. Top left is the data clock, top right & bottom left carry the data.
