  A total of 32 base address settings are available. The switches are a
  binary representation of the decimal memory addresses. JP5 is the Most
  Significant Bit and switch SW1/3 is the Least Significant Bit. The
  switches have the following decimal values: JP5=131072 JP6=65536,
  SW1/1=32768, SW1/2=16384, SW1/3=8192. Turn off the switches and add the
  values of the switches to obtain the correct memory address. (Off=1,
  On=0)
