  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 1=128, 2=64, 3=32, 4=16, 5=8, 6=4, 7=2, 8=1. Turn Off the
       switches and add the values of the Off switches to obtain the
       correct node address. (On=0, Off=1)
