National Instruments cDAQ-9191 CompactDAQ Chassis
The cDAQ-9191 (part numbers: 781497-01, 781497-02) is a CompactDAQ chassis. In hardware, pulse measurement and semi-period have similar estimations. Both measure the high and low times 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 point of data 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 paired sample in units of frequency and duty cycle, high and low time, or high and low ticks. When analyzing information, 10 points in a semi-period estimation will get an array of five high occasions and five low occasions.
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-bit cryptographic calculation recognized 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 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; and operating and non-operating random vibrations of 0.3 grms and 2.4 grms, respectively, at a frequency range of 5 to 500 Hz.

National Instruments cDAQ-9191 Frequently Asked Questions
Question: I have a cDAQ-9191 connected to my Ethernet network and my wireless network. Which connection is preferred in this case?
Answer: The preferred connection is determined by how it was connected. If you prefer a wired connection, find the device in MAX, configure the network settings tab and save. For a wireless connection, follow the same steps, but unplug the Ethernet cable from the chassis and run a self-test to ensure the connection is appropriate, then plug the Ethernet cable back.
Question: Can you connect the cDAQ-9191 to a smartphone?
Answer: You can connect the CompactDAQ Chassis to a smart phone using a firmware upgrade for the chassis.
Question: Can you use your mobile device to wirelessly take voltage measurements from a cDAQ-9191 with a NI-9215 C Series measurement module?
Answer: Yes, after upgrading the firmware, you can use the cDAQ-9191 Data Display app to configure, view, and log measurements on your iOS or Android device, or build your own custom apps using the NI chassis's Web API.
