  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
       1 is the Least Significant Bit and switch 8 is the Most
       Significant Bit. The switches have the following decimal values:
       switch 1=1, 2=2, 3=4, 4=8, 5=16, 6=32, 7=64, 8=128. Turn off the
       switches and add the values of the off switches to obtain the
       correct node address. (On=0, Off=1)
