     the pdf is only the product overview, and so is useless for 
developing a backend. I just couldn't find the full datasheet on the 
various search site I tried, which adds another hurdle.
      Having remote access to the scanner isn't enough. When testing, 
you have to ear and see how the scanner is behaving. And you often turn 
it off and on to reset it to a clean state.
