National Instruments cDAQ-9191 CompactDAQ Chassis

The cDAQ-9191 (Part numbers: 781497-01, 781497-02) is a CompactDAQ Chassis. In hardware, press estimation and semi-period have similar estimations. Both measure the high and low occasions of a pulse. The useful distinction between the two estimations is how the information is returned. In a semi-period estimation, every high or low time is viewed as one purpose of information and returned in units of seconds or ticks. In a pulse estimation, each combination of high and low occasions is viewed as one purpose of information and returned as a matched example in units of frequency and obligation cycle, high and low time, or high and low ticks. When analyzing information, 10 focuses in a semi-period estimation will get a variety of five high occasions and five low occasions. Part number 781497-02 is the international version of the cDAQ-9191, while part number 781497-01 is for the US only. 

The Wi-Fi NI CompactDAQ Chassis executes the most elevated financially accessible remote system security standard, IEEE 802.11i (generally known as WPA2 or WPA2 Enterprise), including system confirmation and information encryption. IEEE 802.1X verification security confirms that exclusive approved gadgets have arranged access, while encryption keeps information from being captured. This CDAQ-9191 CompactDAQ Chassis bolsters different Extensible Authentication Protocol (EAP) techniques that accommodate common confirmation between the information acquisition gadgets and remote passageways (WAPs). The NI cDAQ-9191 additionally bolsters the Advanced Encryption Standard (AES), a 128-piece cryptographic calculation embraced by the National Institute of Standards and Technology for use in numerous U.S. government offices. By utilizing standard security conventions, 802.11 Wi-Fi Chassis make it simple to add remote estimations to existing IT organizations securely. The device has a timing resolution of 12.5 ns.

The cDAQ-9191 is run using the NIDAQmx driver software which can be programmed with software packages or application development environments such as LabVIEW or LabWindows/CVI.

The cDAQ-9191 weighs 17.3 oz (with antenna), and measures 7.98 x 3.49 x 1.32 in. in physical dimensions. It has recommended operating and storage temperature ranges of 0 °C to 55 °C and -10 °C to 70 °C respectively, non-condensing operating and storage humidity ranges of 10% to 90% RH and 5% to 95% RH respectively, operating and non-operating random vibrations of 0.3 grms and 2.4 grms respectively–at a frequency range of 5 to 500 Hz..
