Note: A total of 255 base address settings are available. The switches are a binary representation of the decimal memory addresses. Switch A9 is the Most Significant Bit and switch A5 is the Least Significant Bit. The switches have the following decimal values: switch A9=512, A8=256, A7=128, A6=64, A5=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)
