            Note: A total of 512 base 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=4096, SW1/7=2048, SW1/6=1024, SW1/5=512,
            SW1/4=256, SW1/3=128, SW1/2=64, SW1/1=32. Turn off the
            switches and add the values of the switches that are off to
            obtain the correct memory address. (Off=1, On=0)
