|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 8 is the Least Significant Bit and |
| switch 1 is the Most Significant Bit. The switches have |
| the following decimal values: switch 8=1, 7=2, 6=4, 5=8, |
| 4=16, 3=32, 2=64, 1=128. Turn off the switches and add the|
| values of the off switches to obtain the correct node |
| address. (On=0, off=1) |
