Note: A total of 255 base address settings are available. The switches are a binary representation of the decimal memory addresses. SW1/8 is the Most Significant Bit and switch SW1/1 is the Least Significant Bit. The switches have the following decimal values: SW1/8=32768, SW1/7=16384, SW1/6=8192, SW1/5=4096, SW1/4=2048, SW1/3=1024, SW1/2=512, SW1/1=256. Turn off the switches and add the values of the switches to obtain the correct memory address. (Off=1, On=0)
