NI 9792 WSN Real-Time Gateway
The NI WSN-3212 is a four-channel, low-power, wireless thermocouple input 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

Page 12: Installing The Software
Using the Integrated Panel Mount Slots You can also mount the NI WSN-3212 to a panel using the integrated panel mount slots as shown in Figure 10. 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 13: Installing Batteries
If both battery and external power are connected, the NI WSN-3212 functions from the external power input. The device is designed to provide battery backup in the event of loss of external power and will automatically switch to battery power when external power is lost. - Page 14 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-3212. The power supply must also meet any safety and compliance requirements for the country of use.
