            Note: A total of 64 node address settings are available. The
            switches are a binary representation of the decimal node
            addresses. SW1/6 is the Most Significant Bit and switch SW1/1
            is the Least Significant Bit. The switches have the following
            decimal values: SW1/6=32, SW1/5=16, SW1/4=8, SW1/3=4,
            SW1/2=2, SW1/1=1. Turn on the switches and add the values of
            the switches that are on to obtain the correct node ID.
