Note: A total of 255 node address settings are available. The switches are a binary representation of the decimal node addresses. Switch SW3/8 is the Least Significant Bit and switch SW3/1 is the Most Significant Bit. The switches have the following decimal values: switch SW3/8=1, SW3/7=2, SW3/6=4, SW3/5=8, SW3/4=16, SW3/3=32, SW3/2=64, SW3/1=128. Turn off the switches and add the values of the off switches to obtain the correct node address. (on=0, off=1) | ||||||||
