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