With this flexibility, you can create simple, stand-alone wireless monitoring
networks or completely integrated wired and wireless measurement solutions
that feature access to the full breadth of NI hardware and software platforms.
LabVIEW integration with NI WSNs delivers a common development
environment for your applications as well as rapid application development,
easy network configuration, remote data access, and the ability to program and
customize measurement node behavior.
Overview
The NI WSN-9791 Ethernet gateway coordinates communication between
distributed NI WSN-32xx measurement nodes and a host controller in your NI
wireless sensor network (WSN). The gateway uses a 2.4 GHz, IEEE 802.15.4
radio to gather measurement data from the sensor network and a 10/100 Mbits/s
Ethernet port to provide flexible connectivity to a Windows PC or NI LabVIEW
Real-Time PAC, as seen in Figure 1.
The 9 to 30 VDC externally powered gateway offers -30 to 70 °C operating
temperatures, 50 g shock ratings, and a compact, 2U form factor. Up to
36 measurement nodes can communicate with a single gateway, and you can
configure the Ethernet settings of the gateway for DHCP, static, and link-local
IP address configurations.
Wireless Networking
The NI WSN system is built on a low-power, reliable IEEE 802.15.4 network.
The Ethernet gateway coordinates the wireless network, performing functions
such as device authentication, message buffering, and network topology
administration.
The gateway, routers, and end nodes work together to form a mesh network.
Measurement nodes can operate as routers or end nodes, providing the flexibility
to extend the range of your sensor network. When nodes are configured as
routers, they can repeat messages from end nodes and extend network range
while acquiring measurement data.
Figure 1. NI WSN systems provide flexible connectivity to Windows or LabVIEW Real-Time
host controllers.
NI Wireless Sensor Network Ethernet Gateway
To save power and increase reliability, the network delivers a maximum
theoretical throughput of 250 kbits/s. In general, this correlates to between
30 and 60 samples per minute per channel on the WSN measurement nodes.
You can configure the network to operate on any of the 14 wireless
communication channels to optimize performance and ensure coexistence with
other wireless devices. The external, omnidirectional antenna and internal power
amplifier offer up to 300 m outdoor range with line of sight.
Programming
You can integrate your NI WSN measurement data directly into LabVIEW. After
adding the WSN Ethernet gateway to a LabVIEW project, the nodes configured
with the gateway in MAX are automatically added underneath the gateway in
the project, giving you instant access to their I/O and properties.
Software Overview
With NI-WSN software, you can easily configure your sensor network in the
NI Measurement & Automation Explorer (MAX) configuration utility and quickly
extract measurement data from your wireless sensor network with the LabVIEW
graphical development environment.
Network Configuration
MAX offers an intuitive user interface to add and remove measurement nodes
and configure wireless settings. Upon connection, the WSN-9791 Ethernet
gateway is autodetected under Remote Systems in MAX, and you can assign
measurement nodes to the gateway. The gateway maintains a list of nodes
(by serial number) that have been authorized for network access. When a node
powers up, it scans for available networks, locates either a gateway or router,
and attempts to join it. If the gateway has the node in its list, the node joins the
network, downloads the latest configuration from the gateway, and begins its
normal operation of acquiring measurement data and controlling digital I/O. If a
node is unable to connect, it executes a retry sequence with increasingly higher
wait periods beginning with one minute between connect attempts and ending
with 55 minutes between connect attempts. This preserves battery power if a
gateway is offline.
MAX also offers an overview of the nodes connected to your network
including their last communication time, battery status, and link quality. In
addition, MAX provides an interface to set the wireless communication channel,
configure the gateway IP address, and wirelessly update firmware on the
measurement nodes.

Mechanical Information
The WSN-9791 Ethernet gateway measures approximately 4.6 by 2.3 by 3.5 in.
(L by W by H). The front of the gateway offers power, status, and activity LEDs
in addition to a reset button that you can use to reboot the device. The power
connector and Ethernet port are located on the front, while the DIN-rail and panel
mount plate screw holes are located on the back of the device. The gateway also
includes integrated panel mount holes that are located on the side of the device.
Consult the WSN-9791 user guide for detailed mechanical information.

NI WSN accessories feature options for gateway and measurement node
mounting as well as a weatherproof enclosure for outdoor use of the
measurement nodes. Available mounting accessories include options to panel
mount and DIN-rail mount WSN measurement nodes and gateways. The
NI WSN-3281 magnetic panel mount kit provides easy setup and takedown
on virtually any metal surface. For high shock and vibration applications,
NI recommends a panel mounting configuration rather than DIN-rail.

services for your NI PXI, CompactRIO, or Compact FieldPoint system. The NI Basic
System Assurance Program provides a simple integration test and ensures that
your system is delivered completely assembled in one box. When you configure
your system with the NI Standard System Assurance Program, you can select
from available NI system driver sets and application development environments
to create customized, reorderable software configurations. Your system arrives
fully assembled and tested in one box with your software preinstalled. When
you order your system with the standard program, you also receive system-
specific documentation including a bill of materials, an integration test report,
a recommended maintenance plan, and frequently asked question documents.
Finally, the standard program reduces the total cost of owning an NI system
by providing three years of warranty coverage and calibration service. Use the
online product advisors at ni.com/advisor to find a system assurance program
