            Note: A total of 64 base address settings are available. The
            switches are a binary representation of the decimal memory
            addresses. DS1/6 is the Most Significant Bit and switch DS1/1
            is the Least Significant Bit. The switches have the following
            decimal values: DS1/1=8,192, DS1/2=16,384, DS1/3=32,768,
            DS1/4=65,536, DS1/5=131,072, DS1/6=262,144. Turn off the
            switches and add the values of the switches that are off to
            524,288 to obtain the correct memory address. (Off=1, On=0)
