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