Olympus ringflash pinout

  1. Hello all,

    I may just have been lucky on eBay today, I won an auction for a FS-FC1 flash
    controller. Now, I don't own a ringflash unit, and the auction was for just the
    controller. I want to try to build the strobe heads myself.

    Does anybody know the pinout of the ringflash and twinflash units?

    Apparently the units have six pinned connectors. I have done some thinking and
    I think one pin is earth, one is positive, one trigger. There are some
    modelling lights in these units so that's probably one extra pin as well. I
    think the other two pins are to let the camera know if the flashunit connected
    is a ringflash or one of the twinflash units.
    Am I on the right track here? Does anybody have servicemanuals/ schematics for
    these units?

    Best regards,
