Note: A total of 1023 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 SW1/10 is the Least Significant Bit. The switches have the following decimal values: SW1/1=8192, SW1/2=4096, SW1/3=2048, SW1/4=1024, SW1/5=512, SW1/6=256, SW1/7=128, SW1/8=64, SW1/9=32, SW1/10=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) | ||||||||||
