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