                       DEFAULT CONFIGURATION TOGGLE

                Purpose                                 JP3

   Configuration default toggle first            Pins 2 & 3 closed
                position

   Configuration default toggle second           Pins 1 & 2 closed
                position

       Note:This toggle functions as a clearing of the firmware on the
       board. If the jumper is first on Pins 2 & 3 then changing this
       jumper to Pins 1 & 2 will cause the firmware to be erased and
       default values to be loaded. This will then stay until the jumper
       is moved again.
