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.

MISCELLANEOUS NOTES |
|
The AL-3350 and the AL-3351 have different transceivers. As a result the AL-3350 should only be operated in a coaxial star configuration, while the AL-3351 will operate in a coaxial bus, a coaxial star, a twisted pair bus, or a twisted pair star configuration. |
