   |  Note:A total of 128 node address settings are available.  |
   |  The switches are a binary representation of the decimal   |
   |  node addresses. Switch 7 is the Least Significant Bit and |
   |  switch 1 is the Most Significant Bit. The switches have   |
   |  the following decimal values: switch 1=64, 2=32, 3=16,    |
   |  4=8, 5=4, 6=2, 7=1. Turn Off the switches and add the     |
   |  values of the Off switches to obtain the correct node     |
   |  address. (On=0, Off=1)                                    |
