Note: A total of 255 node address settings are available. The switches are a binary representation of the decimal node addresses. Switch SW1/1 is the Least Significant Bit and switch SW1/8 is the Most Significant Bit. The switches have the following decimal values: jumper SW1/1=1, SW1/2=2, SW1/=4, SW1/4=8, SW1/5=16, SW1/6=32, SW1/7=64, SW1/8=128.Open the switches and add the values of the off switches to obtain the correct node address. (On=0, Off=1) | ||||||||
