Thanks for your Idea Louis   
      
   Unfortunately the Ipad does not have a usb female connector.   
   I would have to setup a wireless interface interface, and the whole   
   construction would be too complicated and expensive.   
      
   I will get into the periscope system to see, if that can bring me a solution.   
      
   Thanks again, Richard
