1. Wireless Sensor Network Overview
The LORD Sensing Wireless Sensor Network is a high-speed, scalable, sensor data acquisition and
sensor networking system. Each system consists of wireless sensor interface nodes, a data collection
gateway, and full-featured user software platforms based on the LORD Sensing Lossless Extended
Range Synchronized (LXRS) data communications protocol. Bi- directional wireless communication
between the node and gateway enables sensor data collection and configuration. Gateways can be
connected locally to a host computer or remotely via local and mobile networks. Some gateways also
feature analog outputs for porting sensor data directly to stand-alone data acquisition equipment.
The selection of available nodes allows interface with many types of sensors, including accelerometers,
strain gauges, pressure transducers, load cells, torque and vibration sensors, magnetometers, 4 to 20 mA
sensors, thermocouples, RTD sensors, soil moisture and humidity sensors, inclinometers, and orientation
and displacement sensors. Some nodes come with integrated sensing devices such as accelerometers.
System sampling capabilities include lossless synchronized sampling, continuous and periodic burst
sampling, and data logging. A single gateway can coordinate many nodes of any type, and multiple
gateways can be managed from one computer with the SensorConnect™ and SensorCloud™ software
platforms. Integration to customer systems can be accomplished using OEM versions of the sensor nodes
and leveraging the LORD Sensing data communications protocol.
Common wireless applications of LORD Sensing Sensing Systems are strain sensor measurement,
accelerometer platforms, vibration monitoring, energy monitoring, environmental monitoring, and
temperature monitoring.

2. Gateway Overview
The WSDA-1500-LXRS is a network gateway designed to configure, co-ordinate, and collect sensor
data from LORD Sensing wireless sensor nodes. The WSDA-1500-LXRS is Ethernet-capable and can
be configured to operate with a static IP, a DHCP-enabled LAN, or as a datalogger to local memory.
The WSDA-1500-LXRS is also capable of pushing sensor data onto a J1939-compatible CAN bus either
by sending all of the sensor messages to one CAN address or by broadcasting user-selected messages
onto the CAN bus.

3. System Operation
The gateway is the interface between LORD Sensing sensor nodes and the data acquisition computer or
network. The gateway co-ordinates the configuration and sampling of the nodes and can handle many
nodes simultaneously. Communication between the nodes and gateway is wireless and uses the LORD
Sensing LXRS and LXRS+ data communications protocols.
LORD Sensing's SensorConnect software program is available for data acquisition from the wireless
sensor network. This is a PC- based software used for configuring gateways and nodes, selecting
sampling modes and parameters, initializing data acquisition, and viewing and saving data.
Communication protocols between the gateway and host computer vary depending on which model
gateway is used.Ethernet gateways have an embedded operating system and utilize a web based
interface for device configuration.
3.1 Software Installation
Install the SensorConnect software on the host computer before connecting any hardware. Access the
free software download on the LORD Sensing website at:
http://www.microstrain.com/software
SensorCloud is an optional data collection, visualization, analysis, and remote management tool. It is
based on cloud computing technology and is accessed directly from a web connection. For more
information go to: http://www.sensorcloud.com/.

3.2 System Connections
To acquire sensor data the following components are needed: a LORD Sensing wireless sensor node,
a LORD Sensing data gateway, and a host computer with access to the data acquisition software.
The sensor, node, gateway, and software selection are application-dependent, but the basic interfaces
are the same. For a connections overview using the WSDA-1500-LXRS refer to

3.3 Gateway Operation
NOTE
The default configuration of Ethernet gateways is for DHCP network connectivity. To change
the gateway communication settings, initial connection to a DHCP- enabled network is
required.
The Ethernet gateway has three primary operating sequences including gateway configuration, node
configuration, and data acquisition, viewing and analysis.
3.4 Gateway Communication
a. Power is applied to the gateway through the power jack on the back of the WSDA-1500-LXRS.
The Ethernet jack must be connected to a DHCP Ethernet network using a CAT5 or better
Ethernet cable. Turn the ON/OFF switch to the On position to power the gateway.
b. Open the SensorConnect software and select Add Device
c. Select the gateway and confirm the IP address shows in the IP Address field. The IP address can
be entered manually in the IP Address field above the Discovered Gateways section. If the
gateway does not appear, confirm that the host computer and the gateway are connected to the
same Ethernet network.

d. Click the green Add Device button.
e. The gateway will appear in the Controller window.

4. Sensor Node Access
4.1 Connect to Nodes
Several methods can be used in SensorConnect to establish communication with the nodes: the
automatic node discovery feature, manually entering the node address, and scanning transmission
frequency and node address ranges.
4.1.1 Add A Node Via Node Discovery
For all LORD Sensing 200 Series nodes, a node discovery is triggered by turning on the node. A
discovery packet is sent from the node to all channels and will appear in SensorConnect. The node
address and frequency are indicated in the documentation included with the node when it is
purchased.
NOTE
Automatic discovery in nodes not included in the LORD Sensing 200 Series will only occur
if the node is set to idle mode. To force boot-up into idle mode, cycle the node power rapidly
two times, and then leave it on. The status indicator on the node will pulse once per second to
indicate it is in idle mode (see Troubleshooting Guide on page 68).
If the base and node are on the same operating frequency, the node will populate below the
Base Station listing when powering on the WSDA-1500-LXRS.
Figure 9 - Node Discovered On Same Frequency

WSDA®-1500-LXRS®User Manual
4.1.2 Add A Node Manually
Adding a node manually requires entering the node address and its current frequency setting.
Figure 11 - Add Node By Address
If the node was successfully added, two confirmation messages will appear and it will be
listed under the Base Station.
Figure 12 - Add Node Confirmation
18
WSDA®-1500-LXRS®User Manual
If the node failed to be added, a failure message will appear. This means the node did not
respond to the base station which could indicate the node is not in idle mode or it may be on
another frequency. If "Add Node Anyway" is selected, it will associate that node with the
channel entered but it is likely there will be a communication error. If the node was not in idle,
move the base station to the frequency of the node and issue a "Set to Idle" command.
Figure 13 - Failure to Add Node
19
WSDA®-1500-LXRS®User Manual
4.1.3 Move Node To Base Station Frequency
If a red circle with a number appears next to Base Station, the node is operating on a
separate radio channel. Select the Base Station and then select the Nodes on Other
Frequencies tile.
Figure 14 - Nodes On Other Frequencies
Highlight the new node being added and select Move Node to Frequency (#).
