Durst Optodapbox, Optodapneg, Optoneg

I have these items, bought quite some time ago, but I don't really know how to use them, and I don't find anything info with google, except some references to a Durst 1200L. Can someone explain me how to use these ? I have a Durst 1200 with colorhead, if that's of any help, but I bought these separatly on a whim ...

Thanks,
Stefan.

Stefan: Please see attached. Hopefully this will provide the information you need.

Thanks Paul ! Exactly what I needed

Regards,
Stefan.
