Connecting the NI 9792 to a Network

Using a standard Category 5 (CAT-5) or better Ethernet cable, connect the NI 9792 to an Ethernet network using the Ethernet port 1 on the NI 9792.

Caution To prevent data loss and to maintain the integrity of your Ethernet installation, do not use

a cable longer than 100 m. If you are using 100 Mbps Ethernet, National Instruments recommends using a CAT-5 or better shielded twisted-pair Ethernet cable.

Note You will configure the IP settings and install software on the NI 9792, as described in the

Configuring IP Settings and Installing Software on the NI 9792 section, after connecting power and

powering the NI 9792 on.

The host computer communicates with the NI 9792 over a standard Ethernet connection. If the host computer is on a network, you must configure the NI 9792 on the same subnet as the host computer. If neither the host computer nor the NI 9792 is connected to a network, you can connect the two directly.

If you want to use the NI 9792 on a subnet other than the one the host computer is on, first connect the NI 9792 on the same subnet as the host computer. Use DHCP to assign an IP address or reassign a static IP address for the subnet where you want it to be and physically move it to the other subnet. The first time you configure the NI 9792, you must also install software on it. Contact your network administrator if you need assistance configuring the host computer and NI 9792 on the same subnet.

Note You must connect Ethernet port 1 to configure the NI 9792. You cannot configure the NI 9792

through Ethernet port 2.

In order to use Ethernet port 2, you must assign a static IP address to the port using MAX. The IP address must be on a different subnet than the IP address of Ethernet port 1. You cannot use DHCP with Ethernet port 2. For more information about using Ethernet port 2, go to

dualenet.

Wiring Power to the NI 9792

Caution You must use a UL Listed ITE power supply marked LPS with the NI 9792. The power

supply must also meet any safety and compliance requirements for the country of use.

Caution You must install the NI 9792 and tighten the captive screws before you apply power to the

NI 9792. Installing the NI 9792 while power is applied to it can cause damage to the device.

1. Install the ferrite shipped with the NI 9792 across the negative and positive leads of the power supply, approximately 50–75 mm (2–3 in.) from the ends of the leads near the NI 9792, as shown in Figure 10.

Figure 10. Wiring Power to the NI 9792

Page 15

2. Connect the positive lead of the power supply to the V1 or V2 terminal and the negative lead to one of the C terminals.

3. Optionally, you can connect the positive lead of another power supply to the other V terminal and the negative lead to one of the C terminals. You must install the ferrite across both pairs of wires.

Note If you connect power to both V1 and V2, you must ensure that the voltage difference between

the two power inputs, measured at the NI 9792 power connector, is at least 500 mV.

Note The NI 9792 draws power from either V1 or V2, depending on which terminal has a higher

voltage. It does not draw power from both terminals. The NI 9792 switches between V1 and V2 without affecting operation.

Caution The C terminals are internally connected to each other. If you use two power supplies, make

sure they share a common ground.

Caution The C terminals are internally connected to the NI WSN 9792 chassis to prevent a faulty

ground connection from causing the chassis ground to float. If you reverse the input voltage, the positive input voltage is connected directly to the chassis. The NI 9792 has built-in reversed-voltage protection, but reversed voltage can damage connected peripherals if the chassis ground is not reliably connected to earth ground.

Caution Do not tighten or loosen the terminal screws on the power connector while the power

connector is plugged into the NI 9792 or while the power supply is on.

Powering On the NI 9792

Turn on each power supply to the NI 9792 system. The NI 9792 runs a power-on self test (POST). During the POST, the POWER and STATUS LEDs turn on. When the STATUS LED turns off, the POST is complete. If the LEDs do not behave in this way when the NI 9792 powers on, refer to the Device

Interface section.

Configuring IP Settings and Installing Software on the NI 9792

Resetting the Network Configuration

If the NI 9792 cannot communicate with the network, you can use the IP RESET switch to manually restore the NI 9792 to the default network settings. When you reboot the NI 9792 with the IP RESET switch in the ON position, the NI 9792 attempts to connect to the network using DHCP. If the NI 9792 is unable to initiate a DHCP connection, it connects to the network with a link-local IP address with the form 169.254.x.x.

Complete the following steps to restore the NI 9792 to the default network settings:

1. Move the IP RESET switch to the ON position.

2. Move the RESET button to cycle power to the NI 9792. The STATUS LED flashes once, indicating that the NI 9792 IP address is unconfigured.

3. Move the IP RESET switch to the OFF position.

You can reconfigure the settings in MAX from a computer on the same subnet. Refer to the Measurement & Automation Explorer Help for more information about configuring the NI 9792 settings.

Note If the NI 9792 is restored to the factory network settings, the LabVIEW run-time engine does

not load. You must reconfigure the network settings and restart the NI 9792 for the LabVIEW run-time engine to load.

Adding, Removing, and Replacing NI WSN-32xx Devices

Use NI MAX to add and remove nodes to and from your NI Wireless Sensor Network. You can remove and insert NI WSN-32xx devices while the system is operating and without powering down the NI WSN system. NI WSN-32xx devices already working in the system remain operational and accessible on the network. Commands sent to a missing NI WSN-32xx device return an error response, but the NI 9792 stores the commands and applies the effects of the commands if a suitable replacement is installed.

When you remove a NI WSN-32xx device and add a new one, the NI 9792 first verifies that the replacement device is compatible with the one that was removed. If it is compatible, the NI 9792 device configures the replacement NI WSN-32xx device with the previous device settings.

NI Wireless Sensor Networks

The NI WSN system is built on an IEEE 802.15.4 wireless mesh network. The 802.15.4 radio in each NI WSN device provides for low-power communication of measurement data across a large network of devices. The NI-WSN software builds on top of that to provide network configuration and reliable communication from the host PC or PAC to the NI WSN-32xx node devices.

Mesh Networking

The NI WSN system consists of two types of devices: gateways and nodes. Gateways act as the network coordinator, in charge of node authentication, message buffering, and bridging from the 802.15.4 wireless network to the wired Ethernet network. Nodes primarily function as end nodes in the network to collect data and control DIO channels, but can also be programmed as routers to relay data from other nodes back to the gateway and Host PC or PAC. Use NI MAX to configure nodes as end nodes or routers. Figure 1 shows a typical NI Wireless Sensor Network.

The gateways and nodes work together to form a mesh network. 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 DIO.

Since each node joins a network instead of a particular router or gateway, it can find a new path back to the gateway in the event that the signal is lost or blocked to its existing network route. In this way, the mesh network is inherently self-forming and self-healing. However, this may also cause network throughput to decrease, as there is no way to force a router or end node to join to a particular device in the network. Each time a node joins through a router, the overall throughput of that node is halved, due to the fact that the node must hop to get its messages back to the gateway. Figure 14 shows an example of one possible mesh configuration.

NI 9792 WSN Real-Time Gateway User Guide and Specifications 22 ni.com

Page 24

Figure 14. Mesh Configuration Example

In this configuration, R1 (a router) and R2 (a router) both communicate directly with the gateway. Measurements taken by both devices can directly reach the gateway without having to hop through another node. However, the configuration above does not always mesh in the same way. Figure 15 shows another possible configuration for the same network.

Page 25

Figure 15. Same Network Configuration Example

In this configuration, R1 can still communicate with the gateway, but R2 is now connected through R1. This means that all measurements taken by R2 must hop through R1 before making it back to the gateway. In addition, R

is now not only responsible for sending its own measurement data, but also

the R2 data. This configuration is considered a worst case 1-hop system, as R2 and R1 both have the possibility of meshing through a router that is connected to the gateway. National Instruments recommends configuring your system for no more than three hops. Configuring multiple nodes as routers and placing them within close proximity introduces the possibility that your system could mesh inefficiently. Figure 16 shows how a system could mesh efficiently, yet also have the possibility of meshing inefficiently.

NI 9792 WSN Real-Time Gateway User Guide and Specifications 24 ni.com

Page 26

Figure 16. Inefficient Versus Efficient Meshing

The network can be improved with two separate techniques:

1. Convert some routers to end nodes.

2. Set up the network to prevent the routers from being in range of each other (spatially separated by distance, or introducing objects that increase radio interference, such as buildings).

Another advantage of the mesh network is the ability to extend the distance of the end measurement from the wired Ethernet gateway. By placing mesh routers throughout the space where you wish to acquire signals, you can expand the area and distance across which measurement data can be acquired and sent. Refer to the Specifications section for typical line of sight ranges for the NI WSN devices. Figure 17 shows how a network can be set up to cover greater distances.

Figure 17. Network Containing Distance Example

Page 27

End Node Versus Router

Each NI WSN-32xx node can be configured as either an end node or a router. NI WSN-32xx nodes are configured by default at the factory in end node mode. You can change the mode of the node using the NI-WSN software and NI MAX. One trade-off to consider when configuring nodes is power consumption. NI WSN-32xx nodes configured as end node are designed to be run from battery power while routers are designed to use external power at all times to send, receive, and buffer messages to and from end nodes.

Data Transfer in the NI WSN Network

The NI WSN system is built on a low-power, reliable IEEE 802.15.4 network. In order to save power and increase reliability, this network delivers a maximum theoretical throughput of 250 kbps. This correlates to a typical maximum rate of 1 sample per second per node.

Measurements taken with NI WSN-32xx nodes are single point acquisition. NI WSN-32xx devices have no onboard buffer, therefore the data is considered to be lost, meaning there is no way to retrieve past data from the device.

Configuring Your NI WSN System

As discussed in the Mesh Networking section, creating a reliable and efficient wireless sensor network requires an understanding of the physical environment of the network, as well as an understanding of the expected meshing configuration. For example, parent devices (routers and gateways) can only have a maximum of eight end nodes connected to them at a given time.

This maximum number introduces the stranded node problem. The stranded node problem exists when a node, configured as an end node, ends up not being able to join a network. Figure 18 shows a network consisting of one gateway, two routers, and nine end nodes.

NI 9792 WSN Real-Time Gateway User Guide and Specifications 26 ni.com

Page 28

Figure 18. Network Containing Distance, Example 1

x 1

x 8

In this case, all nodes have properly meshed, and all nodes can communicate with the gateway. However, this network could potentially strand end nodes. Figure 19 shows another possible mesh of the same network.

Page 29

Figure 19. Network Containing Distance, Example 2

x 1

x 8

In this mesh configuration, eight end nodes in range of both R1 and R2 join with R1. This leaves one end node stranded from the network. This can be corrected in the following two ways:

1. Move the set of eight end nodes to where they can only communicate with R2. This prevents them from possibly joining R

2. Add an additional router that is in range of the single end node. This introduces the possibility of creating additional hops in the network, but also guarantees coverage of all end nodes.
