A total of 128 base address settings are available. The switches are a binary representation of the decimal memory addresses. S2/7 is the Most Significant Bit and switch S2/1 is the Least Significant Bit. The switches have the following decimal values: S2/7=512, S2/6=256, S2/5=128, S2/4=64, S2/3=32, S2/2=16, S2/1=8. Turn off the switches and add the values of the switches to obtain the correct memory address. (Off=1, On=0)
