Note:

A total of 32 base address settings are available. The switches are a binary representation of the decimal memory addresses. S1/1 is the Most Significant Bit and switch S1/5 is the Least Significant Bit. The switches have the following decimal values: S1/5=16, S1/4=32, S1/3=64, S1/2=128, S1/1=256. Turn off the switches and add the values of the switches + 512, to obtain the correct memory address. (Off=1, On=0)
