            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.
