NI Wi-Fi data acquisition (DAQ) devices combine IEEE 802.11 wireless or Ethernet communication; direct sensor connectivity; and the flexibility of NI LabVIEW software for remote monitoring and control of electrical, physical, mechanical, and acoustical signals. NI wireless DAQ devices can stream data on each channel at more than 50 kS/s with 24 bits of resolution. In addition, built-in NIST-approved 128-bit AES encryption and advanced network authentication methods offer the highest commercially available network security. With the flexibility of LabVIEW graphical programming and the ubiquity of 802.11 network infrastructure, Wi-Fi DAQ makes it easy to incorporate wireless connectivity into new or existing PC-based measurement or control systems.
NI wireless DAQ devices consist of an NI C Series measurement module and a Wi-Fi carrier. The NI WLS-9163 is a single module C Series carrier that provides both 802.11b/g and Ethernet connectivity back to a host PC, while the NI ENET-9163 is a single module carrier with only Ethernet connectivity. C Series modules provide direct sensor connections and built-in signal conditioning for a variety of measurements, including temperature, strain, acceleration, current, and voltage. You can use them interchangeably for a variety of measurement and control applications across several platforms, including NI CompactDAQ and CompactRIO, and an NI single module USB carrier. You may purchase WLS-9163 carriers and C Series modules separately or together as NI WLS-9xxx devices:
