  Note: A total of 63 station address settings are available. The
  switches are a binary representation of the decimal station addresses.
  SW1/8 is the Least Significant Bit and switch SW1/3 is the Most
  Significant Bit. The switches have the following decimal values:
  SW1/8=1, SW1/7=2, SW1/6=4, SW1/5=8, SW1/4=16, SW1/3=32. Turn on the
  switches and add the values of the switches to obtain the correct
  station address.
