| Note:A total of 128 node address settings are available. |
| The switches are a binary representation of the decimal |
| node addresses. Switch 7 is the Least Significant Bit and |
| switch 1 is the Most Significant Bit. The switches have |
| the following decimal values: switch 1=64, 2=32, 3=16, |
| 4=8, 5=4, 6=2, 7=1. Turn Off the switches and add the |
| values of the Off switches to obtain the correct node |
| address. (On=0, Off=1) |
