   |  Note: A total of 255 node address settings are available. |
   |  The switches are a binary representation of the decimal   |
   |  node addresses. Switch SW2/1 is the Least Significant Bit |
   |  and switch SW2/8 is the Most Significant Bit. The switches|
   |  have the following decimal values: switch SW2/1=1,        |
   |  SW2/2=2, SW2/3=4, SW2/4=8, SW2/5=16, SW2/6=32, SW2/7=64,  |
   |  SW2/8=128.Turn off the switches and add the values of the |
   |  off switches to obtain the correct node address. (off=1,  |
   |  on=0)                                                     |
