Note: A total of 4095 base address settings are available. The switches are a binary representation of the decimal memory addresses. SW1/1 is the Most Significant Bit and switch SW2/6 is the Least Significant Bit. The switches have the following decimal values: SW1/1=131072, SW1/2=65536, SW1/3=32768, SW1/4=16384, SW1/5=8192, SW1/6=4096, SW1/7=2048, SW1/8=1024, SW2/1=512, SW2/2=256, SW2/3=128, SW2/4=64, SW2/5=32, SW2/6=16. Turn off the switches and add the values of the switches that are off to obtain the correct memory address. (Off=1, On=0)
