I am trying to make an old SB-101 useful.  It is in good shape, and I can make it flash using the TEST button.  However, when I try shorting out each combination of the three pins (two at a time, taking appropriate safety precautions), I can't make it trigger.

 

Am I just not getting the pins deep enough, or do these work on a different principle than PC sync cables?  Does anyone have the specs for the 3-pin Nikonos cables?

Hi GSK3,

 

If you are looking at the cable end, not the camera end, here is the pinout on a 3 prong Nikonos cable.

 

There is an indention in the part that goes into the camera; hold that indention to the 6 o'clock position.

 

Mentally number the pins from left to right as 1,2,3.  Pin 2 will be opposite the indention.

 

Pin 1 = M sync

Pin 2 = Ground  Directly across from the indention.

Pin 3 = X sync

 

M sync is for flashbulbs, so you will be shorting ground to X-sync pin to make the strobe fire.

 

Best of luck,

Barry

Super helpful, thanks. I'll give it a try as soon as work gives me a minute to breathe.


Really appreciate it.

Thanks a lot! I also needed this information. I've just tried an ikelite to nikonos cord on DS51 and it works as you explained.
