Analyzing a Power Line Repeating Network
When running on a PL-20 repeating network, the SmartServer transmits
network messages to the repeating devices with which it can directly
communicate, and those repeating devices in turn relay the messages to
repeating devices located further down the power line, and so on until the
message reaches the target device. The following figure illustrates a repeating
chain that could be used to relay a network management command from the
SmartServer to a target device. In this example, the repeating chain consists of
Repeating Device 1 (a Street Light Bridge module), which relays the message to
Repeating Device 2 (a repeating-enabled luminaire), which relays the command
to Repeating Device 3 (a Street Light Bridge module), which relays the message
to the target device (a luminaire). A luminaire enabled for repeating would use
power line repeating. A Street Light Bridge module could use power line
repeating or forward the message using an RF channel to another Street Light
Bridge module.

You can use the Power Line Repeating Analysis Web page to view the repeating
chain a device is using to communicate with the SmartServer. In addition, you
can use this Web page to analyze and debug the power line repeating network.
