Note:Node address 0 is reserved 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 most significant bit and switch 8 the least significant bit. The switches have the following decimal values: switch 1=128, switch 2=64, switch 3=32, switch 4=16, switch 5=8, switch 6=4, switch 7=2, switch 8=1. Turn Off the appropriate switches and add the values of the ‘off’ switches to obtain the correct node address. |
