   |Note: Nodes can be numbered from 1 to 255. The switches are |
   |a binary representation of the node numbers. When a switch  |
   |is on, the corresponding bit is set to 1 and has the        |
   |following decimal value: SW2/1=128, SW2/2=64, SW2/3=32,     |
   |SW2/4=16, SW2/5=8, SW2/6=4, SW2/7=2, SW2/8=1.               |
