 Data Sheet |
Configure System 
The NI WLS-9215 Wi-Fi data acquisition (DAQ) device includes four channels of simultaneously sampled voltage inputs with 16-bit accuracy to provide minimal phase delay when scanning multiple channels. With both screw-terminal and BNC connector options, the WLS-9215 is designed for flexible and low-cost signal wiring. You can synchronize a WLS-9215 with other devices by using two onboard individually programmable digital trigger lines to export or import sample clocks, start triggers, pause triggers, and reference triggers. In addition, channel-to-earth isolation and calibration traceable to the National Institute of Standards and Technology (NIST) standards provide safety and accuracy for high-quality sensor measurements.
NI Wi-Fi Data Acquisition
NI Wi-Fi data acquisition (DAQ) devices combine IEEE 802.11g wireless or Ethernet communication; direct sensor connectivity; and the flexibility of NI LabVIEW software for remote monitoring of electrical, physical, mechanical, and acoustical signals. With built-in signal conditioning and the highest commercially available network security, NI Wi-Fi DAQ devices stream data in real time for easy-to-use, high-performance remote measurements.
NI-DAQmx Measurement Services Software
NI-DAQmx driver and measurement services software provides easy-to-use configuration and programming interfaces with features such as the DAQ Assistant and automatic code generation to help reduce development time. Every Wi-Fi DAQ device also includes a copy of LabVIEW SignalExpress LE software so you can quickly acquire, analyze, and present data without programming.
Application Software
In addition to LabVIEW SignalExpress, Wi-Fi DAQ devices are compatible with the following versions (or later) of NI application software: LabVIEW 7.1¹, LabWindows™/CVI 7.x, and Measurement Studio 7.x. Wi-Fi DAQ devices are also compatible with ANSI C/C++, C#, Visual Basic .NET, and Visual Basic 6.0.
¹ NI-DAQmx 8.8 (and later) provides support for NI LabVIEW 7.1, 8.2, 8.5, 8.6, and later.
