            Note: A total of 255 node address settings are available. The
            switches are a binary representation of the decimal memory
            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 to obtain the correct memory
            address. (Off=1, On=0)
