Setting up a network
14
NXR-ZGW-PRO NetLinx ZigBee Pro Gateway & NXR-ZRP-PRO NetLinx ZigBee Pro Repeater
With an AMX system, the AMX NXR-ZGW-PRO fills that role. Multiple routers may be contained in a
ZigBee network, and the routers must have a reliable power source to keep the network assembled. ZigBee
messages travel through the network, attempting to minimize the hops between source and destination.
Routers, including the Coordinator, share routing information and establish paths through the network, which
is illustrated by the solid lines in FIG. 7.
Devices may only have one parent, usually a single router. However, they may be within range of multiple
routers, and choose to roam to a new parent based on signal strength, packet error rate, or some other
measurable data. The possible connections between devices and the routers in range are illustrated by the
dashed and dotted lines in FIG. 7.
Only one of these paths between a device and a router will be active until the device chooses to roam and find
a new parent. The active path is illustrated by the dotted lines. The active path may not always be the path with
the fewest hops through the network.
For example, if a device is moved behind a wall with sufficient RF absorption, the device may roam to a parent
with a stronger signal.
Devices may be mobile and may go into Standby Mode. Due to the mobile nature, previously out-of-range
routers may come within range and be roamed to as the device moves through the RF space. Due to the nature
of a typical standby cycle, in order to save battery life, a device will control the rate of the data it receives
based on its standby cycle.
Entering Devices Onto a Network
After establishing the location of the gateway (page 9), connecting it (page 11), providing power (page 10),
and placing the device in either a rack (page 11) or wall installation (page 11), you can then begin configuring
the NXR-ZGW-PRO and adding an NXR-ZRP-PRO and other ZigBee-compatible devices to the network.
1.
Confirm that the NXR-ZGW-PRO is receiving power by checking the PWR LED on the front panel.
2.
Using a PC connected to your NetLinx system, either open a web browser equipped with Zeroconf or
NetLinx Studio.
The NXR-ZGW-PRO will show up in the Zeroconf list as
AMX NXR-ZGW SN# XXXX
(“XXXX”
being the 16-digit serial number of the NXR-ZGW-PRO).
Double click on the device and the NXR-ZGW Browser-Based Configuration Manager will be
brought up.
If Zeroconf is not available, open a telnet session with the master and use the command “show
system” to obtain the IP address of the NXR-ZGW-PRO.
If more than one master is on the subnet, the NXR-ZGW-PRO will connect to the first one it senses,
so having only one master is highly recommended.
3.
Access the NXR-ZGW on-line Configuration pages - enter the IP address of the NXR-ZGW-PRO into
your web browser (the default IP configuration for the NXR-ZGW-PRO is
DHCP/Zeroconf
).
4.
Select the
NetLinx Settings
tab, and configure the NXR-ZGW-PRO to communicate with the master. See
the
Configuration - NetLinx Settings tab
section on page 22 for details.
5.
Go to the
PAN/Network
tab and enable the wireless network. See the
Personal Area Network (PAN) -
Network tab
section on page 24 for details.
6.
Turn on and/or configure ZigBee-compatible devices one at a time, e.g., Mio R-3 or Mio R-4. This
ensures that they are fully booted up before attempting to join the network.
7.
Go to the
Pan/Commissioning
tab and allow joining. This enables joining for one minute and may need to
be repeated periodically. See the
Personal Area Network (PAN) - Commission Devices tab
section on
page 27 for details.
8.
Start a network scan and select the appropriate Extended PAN ID (
Mio R-3 and R-4 only
).
9.
For devices that do not have displays, such as the NXR-ZRP-PRO, or ones that have an insufficient
display to allow selection of the Extended PAN ID to join a network, place each device one at a time
within range of the gateway, turn on one of the devices, and configure it using the gateway web pages
before turning on the next one. With repeaters that have been on for some time, shut them down and
reboot them. Use the gateway to lock the device to the desired Extended PAN ID.
