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 Least Significant Bit and switch SW1/1 is the Most Significant Bit. The switches have the following decimal values: SW1/8=8, SW1/7=16, SW1/6=32, SW1/5=64, SW1/4=128, SW1/3=256, SW1/2=512, SW1/1=1024. Turn off the switches and add the values of the switches to obtain the correct memory address. (Off=1, On=0) | ||||||||
