Note:Node address 0 is used for messaging between nodes and must not be used. A total of 255 node address settings are available. The switches are a binary representation of the decimal node addresses. Switch 1 is the Least Significant Bit and switch 8 is the Most Significant Bit. The switches have the following decimal values: switch 8=128, 7=64, 6=32, 5=16, 4=8, 3=4, 2=2, 1=1. Turn Off the switches and add the values of the Off switches to obtain the correct node address.
