Note: A total of 255 node address settings are available. The switches are a binary representation of the decimal node addresses. SW1/1 is the Most Significant Bit and switch SW1/8 is the Least Significant Bit. The switches have the following decimal values: SW1/1=128, SW1/2=64, SW1/3=32, SW1/4=16, SW1/5=8, SW1/6=4, SW1/7=2, SW1/8=1. Turn off the switches and add the values of the switches that are off to obtain the correct node ID. (Off=0, On=1)
Node address 0 is reserved and should not be used.
