Note: 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=2048, S1/6=1024, S1/5=512, S1/4=256, S1/3=128, S1/2=64, S1/1=32. Turn off the switches and add the values of the switches that are off to obtain the correct memory address. (Off=1, On=0) | ||||||||
