Howdy.. if you figure it out let me know by email please. THE protocol
is the same as the cheap chinese scales. Littlemachineshop.com has the
pictures and explanation better than I can. It is a two channel
continous burst transmission with null periods, second channel is a
clock if I remember.

I'd love to use the old single board computer as a dro on my lathe.
CHEAP..
