  A total of 255 base address settings are available. The switches are a
  binary representation of the decimal memory addresses. U2/8 is the Most
  Significant Bit and switch U2/1 is the Least Significant Bit. The
  switches have the following decimal values: U2/8=32768, U2/7=16384,
  U2/6=8192, U2/5=4096, U2/4=2048, U2/3=1024, U2/2=512, U2/1=256. Turn
  off the switches and add the values of the switches to obtain the
  correct memory address. (Off=1, On=0)
