Note:

A total of 255 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 S1/8 is the Least Significant Bit. The switches have the following decimal values: S1/1=512, S1/2=256, S1/3=128, S1/4=64, S1/5=32, S1/6=16, S1/7=8, S1/8=4. Turn off the switches and add the values of the switches to obtain the correct memory address. (Off=1, On=0)
