I haven't used that type of encoder but it sounds similiar to a standard rotary

encoder, you might want to look at the application notes related to the rotary
encoders.

Did you find the information about the binary chain code in the application note
s for
the device or from some other source?  If its from another source could you site
 the
reference? I would be interested in hearing more about this project and how it t
urns
out.
