NI 9792 WSN Real-Time Gateway
The NI WSN-3226 is a four-channel, low-power, wireless voltage/resistance device that works with
other NI WSN-32xx nodes and gateways to form a wireless sensor network. The NI WSN system
consists of one or more NI WSN gateways, up to 36 NI WSN-32xx nodes per gateway, and multiple PCs
or Programmable Automation Controllers (PACs) to receive and analyze the distributed sensor data. For
more information about PACs, visit
When you connect the NI WSN gateway, you can use a separate host PC running Windows, or a PAC
running NI LabVIEW Real-Time, to display measurement results, status information, and to change the
NI WSN gateway and NI WSN-3226 device settings.

Using the Integrated Panel Mount Slots You can also mount the NI WSN-3226 to a panel using the integrated panel mount slots as shown in Figure 9. Attach three number 8 or M4 pan head screws in the mounting panel, leaving 0.1 in. space under the head of each screw. -
Page 12: Installing Batteries
Powering the NI WSN-3226 Device The NI WSN-3226 device can be powered by either an external power supply or four AA alkaline or lithium batteries. Refer to the Specifications section for details about the input power and battery requirements. If both battery and external power are connected, the NI WSN-3226 functions from the external power input. - Page 13 Reinstall the 2-position mini-combicon plug in the device and tighten the retaining screws. Caution You must use a UL Listed ITE power supply marked LPS with the NI WSN-3226. The power supply must also meet any safety and compliance requirements for the country of use.

Refer to your NI WSN gateway documentation for detailed instructions about how to connect a NI WSN-3226 to the NI WSN gateway. The NI WSN-3226 is equipped with a WSN connect button as shown in Figure 12. The button controls network connection and the LEDs, which display connection status. - Page 17 In voltage mode, the NI WSN-3226 supports single-ended DC measurements. Each channel has an AI and a COM terminal to which you can connect a voltage signal. Figure 13 shows the NI WSN-3226 input circuitry in voltage mode. To measure a voltage signal, connect the positive lead to the AI terminal, and the ground lead to the adjacent COM terminal.
- Page 18 Figure 16 shows an example of connecting a RTD to the NI WSN-3226. NI WSN-3226 Figure 16. Connecting a RTD The NI WSN-3226 sources different current levels on the EX terminal depending on the selected range. For more information about the current source value for each range, refer to the Specifications section.
- Page 19 A, B, C are coefficients given in Table 3 Table 3 lists the coefficients used in this equation for the TCR values that the NI WSN-3226 supports. If you have a nonstandard RTD that does not match one of these linearization curves, measure the RTD in the resistance mode of NI WSN-3226, and convert the resistance to temperature in the manner suggested by the RTD vendor.
- Page 20 Use the Node Properties dialog box in the LabVIEW Project Explorer window to change DIO settings. The NI WSN-3226 device has two bi-directional digital I/O channels. Each channel supports eight operational modes depending on whether the channel is configured as digital output or digital input.
- Page 21 You can connect only one external DIO PWR supply to the NI WSN-3226. The power supply provides the current for the devices you connect to the NI WSN-3226. Connect the power supply positive lead to DIO PWR terminal and the power supply negative lead to one of the DGND terminals.
