7.
From the main workspace of HotView Pro, right-click the head node
> Peer
Node Configuration
8.
Enter the serial number of the node that you want to appear.

10.
Remove the Ethernet cable from the first node, and attach it to the other
node. That node is now the head node.
11.
From the node that you just configured, right-click the node
> Peer Node
Configuration
12.
From the main workspace of HotView Pro, right-click the head node
> Peer
Node Configuration
13.
Enter the serial number of the node that you want to appear.

After multiple reboots a node is missing
If a node reboots five times within 10 minutes, the node loads the second saved
firmware image.
The previous firmware, if older or different from the firmware of the other nodes
in a mesh network, might not be recognized by the mesh, and HotView Pro will
not detect the node.
To prevent this behavior, always upgrade the firmware image on each node two
times, so both images are the same.
Ethernet port LEDs blink quickly
If the Ethernet port LEDs blink quickly, check for a switch loop.
Performance not as expected
If the network performance is not as expected:
•
Identify reuse in your channel plan. If you have no channel reuse in the
network, do a spectrum analysis.
•
Check for self-interference. For example, the radios in a single device might
connect.
•
Check the frequency plan and make sure that all the radios are configured
correctly.
•
Make sure that each node is connected to the correct devices and nodes.
•
Determine the total throughput with an end to end test.
•
Determine the throughput of each link with tests.
•
Change the channel and modulation rates.
•
Overly strong or poor RSSI can cause low performance. The RSSI calculator
can help determine what RSSI values are correct for a particular link.
-
For MIMO applications, use -30 to -55.
-
For non-MIMO applications, use -30 to -60 or -70.
