This coupled with the schematic confirm my memory. And I believe that schematic is from the VCS Field Service Manual, but I don't have time to check right now. The 2 bits used are the least significant bits of the encoder. (Yes, it is definitely a rotary encoder.) So the pattern will repeat 4 times if you move the controller through one full rotation. -Chris - Archives (includes files) at http://www.biglist.com/lists/stella/archives/ Unsub & more at http://www.biglist.com/lists/stella/
