and click all other devices to be viewed, or hold down SHIFT and select another device to view
the entire range of devices.
3. You can identify repeating devices (devices that 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 devices than can directly receive messages from the SmartServer without any repeating are
listed under the Direct Communication column. The direct communication device relays
messages to the next repeating device in the chain. A device that can relay messages to other
devices is referred to as a “proxy”.
The repeating devices (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 repeating device that directly communicates with the SmartServer (a proxy) is listed
under the Direct Communication column.
• The next repeating device in the repeating chain (a proxy), which does not have direct
communication with the SmartServer, is listed under the Proxy Zone 1 column.
• The repeating device 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.
4. You can display statistics related to the power line signal at the hop between a repeating device
and the next device in the repeating chain by selecting the following check boxes at the top of the
Web page (you can view all the statistics by clicking the Display All Available Information
check box):
