9. You can identify proxies (repeating devices that can relay messages to devices located further
down the channel) and target devices (the destination device in a repeating chain) by observing
whether there is a device listed in the column to the right. If there is no device listed in the column
to the right, that device is a target device.
The SmartServer is always listed under the Center column as all network messages originate from
its local LonTalk device (Net/LON/LtaLdv).
The direct communication devices (proxies or target devices than can directly receive messages
from the SmartServer without any repeating) are listed under the Direct Communication column.
The direct communication devices can relay messages to proxies and target devices further down
the power line.
The proxies and target devices are listed under the Proxy Zone columns. The last repeating
device in the chain before the target device is referred to as the “proxy agent”.
For example, if a target device uses four hops to receive a message, you would observe the
following:
• The proxy in the repeating chain that directly communicates with the SmartServer is listed
under the Direct Communication column.
• The next proxy in the repeating chain, which does not have direct communication with the
SmartServer, is listed under the Proxy Zone 1 column.
• The proxy that can directly communicate with the target device (the proxy agent) is listed
under the Proxy Zone 2 column.
• The target device is listed under the Proxy Zone 3 column.
If a target device requires the maximum eight hops, you can scroll to the right to Proxy Zone 7
column to view the target device and its repeating chain to the left.
10. You can display statistics related to the power line signal at the hop between a device and its proxy
by selecting the following check boxes at the top of the Web page (you can view all the statistics
