   |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)                                    |
