  Note:Node address 0 is used for messaging between nodes and must not be
  used.

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