Note: A total of 255 node address settings are available. The switches are a binary representation of the decimal node addresses. Switch SW2/1 is the Least Significant Bit and switch SW2/8 is the Most Significant Bit. The switches have the following decimal values: switch SW2/1=1, SW2/2=2, SW2/3=4, SW2/4=8, SW2/5=16, SW2/6=32, SW2/7=64, SW2/8=128.Turn off the switches and add the values of the off switches to obtain the correct node address.
