                                   Note:

  A total of 255 base address settings are available. The switches are a
  binary representation of the decimal memory addresses. SW3/8 is the
  Most Significant Bit and switch SW3/1 is the Least Significant Bit. The
  switches have the following decimal values: SW3/8=512, SW3/7=256,
  SW3/6=128, SW3/5=64, SW3/4=32, SW3/3=16, SW3/2=8, SW3/1=4. Turn off the
  switches and add the values of the switches to obtain the correct
  memory address. (Off=1, On=0)
