Note: A total of 64 base address settings are available. The switches are a binary representation of the decimal memory addresses. SW1/6 is the Most Significant Bit and switch SW1/1 is the Least Significant Bit. The switches have the following decimal values: SW1/6=262,144, SW1/5=131,072, SW1/4=65,536, SW1/3=32,768, SW1/2=16,384, SW1/1=8,192. Turn off the switches and add the values of the switches that are off to 524,288 to obtain the correct memory address. (Off=1, On=0)
