|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 1=1, 2=2, 3=4, 4=8, |
| 5=16, 6=32, 7=64, 8=128. Turn off the switches and add the|
| values of the off switches to obtain the correct node |
| address. (On=0, Off=1) |
