Re: Serial Port to Calipers

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..
