Note:
A total of 48 base address settings are available. The switches are a binary representation of the decimal memory addresses. SW1/6 is the Most Significant Bit and switch SW1/1 is the Least Significant Bit. The switches have the following decimal values: SW1/6=512, SW1/5=256, SW1/4=128, SW1/3=64, SW1/2=32, SW1/1=16. Turn off the switches and add the values of the switches to obtain the correct memory address. (Off=1, On=0)
