Note: A total of 253 node address settings are available. The switches are a binary representation of the decimal node addresses. SW1/10 is the Most Significant Bit and switch SW1/3 is the Least Significant Bit. The switches have the following decimal values: SW1/10=128, SW1/9=64, SW1/8=32, SW1/7=16, SW1/6=8, SW1/5=4, SW1/4=2, SW1/3=1. Turn on the switches and add the values of the switches that are on to obtain the correct node address. (Off=0, On=1)Addresses 0 and 255 are reserved and should not be used. |
