   |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)                                    |
