NI WSN-3230/3231

NI Wireless Sensor Network RS-232/RS-485 Serial Interface Nodes

This user guide describes how to use the NI WSN-3230/3231 RS-232/RS-485 interface serial nodes and 
lists their specifications. Figure 1 shows the NI WSN system components. The NI WSN-3230 is a low 
power wireless node with one RS-232 port. The NI WSN-3231 is a low power wireless node with one 
RS-485 port. These nodes work with other NI WSN-32

xx

 nodes and gateways to form a wireless sensor 

network. 

Figure 1.  

NI WSN System Components

The NI WSN system receives and analyzes distributed sensor data through one or more NI WSN 
gateways, up to 36 NI WSN nodes per gateway, and multiple PCs. 

When you connect the NI WSN gateway, you can use a separate host PC running Windows, or a 
NI CompactRIO chassis running NI LabVIEW Real-Time, to display measurement results, status 
information, and to change the NI WSN gateway and NI WSN-3230/3231 device settings.
