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