Note: A total of 512 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=4096, SW1/7=2048, SW1/6=1024, SW1/5=512, SW1/4=256, SW1/3=128, SW1/2=64, SW1/1=32. Turn off the switches and add the values of the switches that are off to obtain the correct memory address. (Off=1, On=0)

SW1/1 must be off on the Octacable card.
