|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) |

| Note: Some examples of possible settings are shown. The |
| switches are a binary representation of the hexadecimal |
| I/O addresses. Switch 6 is the Least Significant Bit and |
| switch 1 is the Most Significant Bit. The switches have |
| the following decimal values: switch 6=1h, 5=2h, 4=4h, |
| 3=8h, 2=10h, 1=20h. Turn off the switches, add the values |
| of the off switches, and multiply the total by 10h to |
| obtain the correct I/O address. (On=0, Off=1) |
