            Note: A total of 48 base address settings are available. The
            switches are a binary representation of the decimal memory
            addresses. SW2/1 is the Most Significant Bit and switch SW2/6
            is the Least Significant Bit. The switches have the following
            decimal values: SW2/1=512, SW2/2=256, SW2/3=128, SW2/4=64,
            SW2/5=32, SW2/6=16. Turn off the switches and add the values
            of the switches to obtain the correct memory address. (Off=1,
