Note: A total of 96 base address settings are available. The switches are a binary representation of the decimal memory addresses. SW1/7 is the Least Significant Bit, and switch SW1/1 is the Most Significant Bit. Turn off the switches and add the values of the switches to obtain the correct memory address. (Off=1, On=0). Low address settings will leave some ports disabled. Ports may not be assigned addresses below 100h.
