Note: A total of 127 base address settings are available. The switches are a binary representation of the decimal memory addresses. SW1/7 is the Most Significant Bit and switch SW1/1 is the Least Significant Bit. The switches have the following decimal values: SW1/7=8388608, SW1/6=4194304, SW1/5=2097152, SW1/4=1048576, SW1/3=524288, SW1/2=262144, SW1/1=131072. Turn off the switches, add the values of the switches, and convert to hexadecimal to obtain the correct memory address. (Off=1,On-0). To obtain the Kilobyte memory size, divide the decimal value of the memory address by 1024, and to obtain the megabyte size divide by 1024 again.
