                                   Note:

  A total of 255 base address settings are available. The switches are a
  binary representation of the decimal memory addresses. SW1/8 is the
  Most Significant Bit and switch SW1/1 is the Least Significant Bit. The
  switches have the following decimal values: SW1/8=32768, SW1/7=16384,
  SW1/6=8192, SW1/5=4096, SW1/4=2048, SW1/3=1024, SW1/2=512, SW1/1=256.
  Turn off the switches and add the values of the switches to obtain the
  correct memory address. (Off=1, On=0)
