Note: A total of 64 node address settings are available. The switches are a binary representation of the decimal node addresses. SW1/6 is the Most Significant Bit and switch SW1/1 is the Least Significant Bit. The switches have the following decimal values: SW1/6=32, SW1/5=16, SW1/4=8, SW1/3=4, SW1/2=2, SW1/1=1. Turn on the switches and add the values of the switches that are on to obtain the correct node ID. (Off=0, On=1) | ||||||
