NI 9792 WSN Real-Time Gateway
The NI WSN-3202 is a four-channel, low-power, wireless voltage 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
