   | |Notes: 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)                   |
