Note: One dynamic and 127 specific node address settings are available. The switches are a binary representation of the decimal node addresses. Switch SW3/7 is the Least Significant Bit and switch SW3/1 is the Most Significant Bit. The switches have the following decimal values: switch SW3/7=1, SW3/6=2, SW3/5=4, SW3/4=8, SW3/3=16, SW3/2=32, SW3/1=64. Turn off the switches and add the values of the off switches to obtain the correct node address. (on=0, off=1) |
