Hi Peter,

I have now found a link to a pdf which is specifically about interfacing Chinese verniers. There is a good explanation of the signals and connections. It's the best I can do for now..

This is the link: http://www.lima.com.tr/BasicTiger/Applications/PDF/appn_066e_Reading%20out%20a%20digital%20vernier%20caliper.PDF
