            Note: A total of 32 base address settings are available. The
            switches are a binary representation of the decimal memory
            addresses. SW1/10 is the Most Significant Bit and switch
            SW1/5 is the Least Significant Bit. The switches have the
            following decimal values: SW1/10=256, SW1/9=128, SW8/10=64,
            SW1/7=32, SW1/6=16. Turn off the switches and add the values
            of the switches to 512 and convert to hexadecimal to obtain
            the correct memory address. (Off=1, On=0)
