                        INTERRUPT SOURCE SELECTION

                 Function                        Label          Position

  Selects interrupts caused by the              EXT/EOC        Pins 1 & 2
  end-of-conversion signal                                       closed

  Selects external interrupts                   EXT/EOC        Pins 2 & 3

  Note: The end-of-conversion interrupt is to be used only when the
  counter/timer or an external event are used to start A/D conversions.
  Use of the AUTO jumper or Software Start with the interrupts will
  degrade card speed.

  A total of 128 base address settings are available. The switches are a
  binary representation of the decimal memory addresses. S1/7 is the Most
  Significant Bit and switch S1/1 is the Least Significant Bit. The
  switches have the following decimal values: S1/7=512, S1/6=256,
  S1/5=128, S1/4=64, S1/3=32, S1/2=16, S1/1=8. Turn off the switches and
  add the values of the switches to obtain the correct memory address.
