   |     Note: A total of 255 node address settings are         |
   |     available. The switches are a binary representation of |
   |     the decimal node addresses. SW1/8 is the Most          |
   |     Significant Bit and switch SW1/1 is the Least          |
   |     Significant Bit. The switches have the following       |
   |     decimal values: SW1/8=128, SW1/7=64, SW1/6=32,         |
   |     SW1/5=16, SW1/4=8, SW1/3=4, SW1/2=2, SW1/1=1. Turn off |
   |     the switches and add the values of the switches that   |
   |     are off to obtain the correct node ID. (Off=1, On=0)   |
   |                                                            |
   |     Node address 0 is reserved and should not be used.     |
