Signal Strength Direct Communication Devices: Displays the reduction
in signal strength at the device in decibels (dB).
Proxies: The reduction in signal strength at the hop in
decibels (dB). This value is the minimum of the signal
strengths measured at the selected device and the proxy.
Signal Margin Direct Communication Devices: The amount in decibels
(dB) that the signal margin exceeds the recommended
amount calculated by the SmartServer for reliable
communications at the device.
Proxies and Target Devices: The amount in decibels (dB)
that the signal margin exceeds the recommended amount
calculated by the SmartServer for reliable communications at
the hop.
Failure History Provides a historical list of the 45-minutes intervals since the
Segment Controller was rebooted in which a device failure (if
any) was reported.
For example, if failures are recorded for the device on
Monday at 14:30, Tuesday at 15:00, Wednesday at 16:00, and
Saturday at 16:15, this property would display the following
text:
Failure 14:15-15:00
Failure 15:45-16:30
The device failure history is cleared when a device has no
failures during a 7-day period.
Last Time
Reached
Displays the time at which the device last responded to a
network message.
Note: The number of proxies displayed in this dialog might differ
from the number shown in the Power Line Repeating Analysis Web
page as the Segment Controller updates cached data. To view an
updated list of available proxies in this dialog, close this dialog, click
Refresh in the Power Line Repeating Analysis Web page, right-click
the device, and then select Show Available Proxies in the shortcut
menu.
d. You can click Refresh to get the latest cached signal strength
and signal margin measurements.
e. Click Close to return to the Power Line Repeating Analysis Web
page.
Adding Devices
After you install a power line repeating network, you can use the Segment
Controller to add new devices to the network. The process for adding new devices
to an existing network is the same as initially installing the network. See
Manually Installing a Street Lighting Network on page 48 for more information
about installing devices with the Segment Controller.
