Note: A total of 64 base address settings are available. The switches are a binary representation of the decimal memory addresses. DS1/6 is the Most Significant Bit and switch DS1/1 is the Least Significant Bit. The switches have the following decimal values: DS1/1=8,192, DS1/2=16,384, DS1/3=32,768, DS1/4=65,536, DS1/5=131,072, DS1/6=262,144. 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)
