            Note: A total of 256 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=1024, SW1/7=512, SW1/6=256, SW1/5=128,
            SW1/4=64, SW1/3=32, SW1/2=16, SW1/1=8. Turn off the switches
            and add the values of the switches that are off to obtain the
            correct memory address. (Off=1, On=0)
