            Note:A total of 63 node address settings are available. The
            switches are a binary representation of the decimal node
            addresses, and have the following decimal values: 1=1, 2=2,
            3=4, 4=8, 5=16, 6=32. Switches in the off position maintain a
            zero value. Sum total the switches in the on position to
            obtain the correct node address. Node 0 is a non-valid
            address.
