Note: A total of 1024 base address settings are available. The switches are a binary representation of the decimal memory addresses. SW2/10 is the Most Significant Bit and switch SW2/1 is the Least Significant Bit. The switches have the following decimal values: SW2/10=512, SW2/9=256, SW2/8=128, SW2/7=64, SW2/6=32, SW2/5=16, SW2/4=8, SW2/3=4, SW2/2=2, SW2/1=1. Turn off the switches and add the values of the switches that are off to obtain the correct memory address. (Off=1, On=0)
