3.1.2 Elster A3/Alpha Plus Node Layout
Figure 3.3 below is a simple diagram of an Elster A3/Alpha Plus node. The
primary components of the node are:
• the meter interface connector - connects the node to the meter
• the node’s serial number - the node’s unique identifier
• LEDs - red and green lights displaying node’s operating status
Each Elster A3/Alpha Plus node is uniquely identified with a serial number. This
number is displayed on the label and is contained on the bar code. In addition,
the number is also embedded in the node’s software. This serial number is the
number displayed on the Field Tool and Network Manager to identify the node.
