62 Managing a Street Lighting Network
Frequency in Use Displays the frequency carrier of the signal at the hop
(Primary or Secondary). For more information on the use
of these frequency carriers on a L
ONWORKS power line
channel, see the LonWorks PLT-22 Power Line Transceiver
User’s Guide (110kHz - 140kHz Operation).
For RF hops, Primary or Secondary refer to the CRD 3000
Street Light Bridge module’s primary or secondary channel
lists.
Signal Strength Direct Communication Devices: Displays the real-time
measurement in dB of the signal strength at the device.
Proxies and Target Devices: Displays the real-time
measurement (in dB for power line hops; in dBm for RF hops)
of the signal strength at the hop. This value is the minimum
of the signal strengths measured at the device and its 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.
c. You can click Refresh to get updated real-time values.
d. Click Close to return to the Power Line Repeating Analysis Web
page.
7. Optionally, you can view statistics related to signal at the hop between
the selected device and all the proxies (repeating devices) that can be
used to relay messages to that device, including the current proxy. To
view the available proxies for a given device, perform the following steps:
a. Right-click the device and select Show Available Proxies from
the shortcut menu.
b. The Show Available Proxies dialog opens.
