       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)
