•
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.
Resetting an outdoor node to factory default settings
Do a reset when you remove a device from the field or when communication with
a device is lost.
Caution!
When a HotPort 5020 edge node is reset, configuration
information is erased.
Exception:
The system does not erase the USA (840 and 842) country
codes.
You can reset a HotPort 5020 edge node with the reset button. The reset button
is behind the pressure relief valve on the bottom panel of the node.
For this procedure you need:
•
Paper clip, stiff wire, or thin piece of plastic or wood, such as a skewer
•
Computer with HotView Pro
•
Ethernet cable
•
Wrench or your fingers to turn the pressure valve
To reset a HotPort 5020 edge node:
1.
Supply power to the node.
Wait until the status LED comes on. After one minute, the node is ready to be
reset.
2.
With a wrench or your fingers turn the pressure valve counter clockwise to
remove it.
3.
Put it in a safe place until you finish this procedure.
4.
Put the node on its front panel.
5.
Press and hold for 20 seconds the reset button with the paper clip or other
tool.
When the Radio 1 LED blinks to indicate that the software is rebooting, you
can stop pressing the reset button.
6.
Wait one minute, and then log in with HotView Pro.
7.
Configure the node or apply a previously saved configuration file.
8.
Replace the pressure valve that covers the reset button.
Scheduling firmware upgrades and activation
By default, the system uses the configuration in cache for multiple upgrades.
