National Instruments cDAQ-9188 CompactDAQ Chassis

The cDAQ-9188 (Part Numbers: 781424-01, 782824-01, 190672G-01L) The CompactDAQ chassis allows the user to utilize DAC to produce a waveform so they may see glitches on the output signal. These glitches are ordinary; glitches will be produced from released charges when a DAC changes, starting with one voltage and then moving on to the next. The biggest glitches happen when the most significant bit of the DAC code changes. Users can construct a low-pass deglitching channel to remove a portion of these glitches, contingent upon the frequency and nature of the output signal. Each of the DIO lines can be used as either a static DI or DO line. The user can utilize static DIO lines to screen or control advanced signals on some C Series modules. Each DIO line can be exclusively designed for digital input (DI) or digital output (DO) if the C-Series module being utilized permits such a setup. Users can gain advanced waveforms utilizing either parallel or serial computerized modules. The DI waveform securing FIFO secures the computerized tests. The NI cDAQ-9188 chassis tests the DIO lines on each rising or falling edge of the DI sample clock flag.

The user can utilize the DI Sample Clock (di/SampleClock) signal to test computerized I/O on any space using parallel advanced modules and store the outcome in the waveform procurement FIFO. The cDAQ-9188 is equipped with 8 slots and an Ethernet bus connector and has a timing resolution of 12.5 ns. It has a voltage input range of 9 V to 30 V and a maximum power requirement of 15 W.

The cDAQ-9188 is operated using the NI-DAQmx 9.2 driver software, which is a software package/application development environment (ADE) such as LabVIEW, LabWindows/CVI, Visual C#, Visual Basic .NET, or Measurement Studio. The device hardware can be configured using the Measurement & Automation Explorer (MAX) tool.

The cDAQ-9188 weighs 31.7 oz. and measures 10.00 x 3.47 x 2.32 in. It has a recommended operating temperature range of 20°C to 55°C.

National Instruments cDAQ-9188 Frequently Asked Questions

 

Question: How many counter/timer operations can be run simultaneously on the cDAQ-9188?

Answer: The cDAQ chassis can run seven hardware-timed analog I/O, digital I/O, or counter/timer operations simultaneously.

 

Question: How do you access the counters in the cDAQ-9188 chassis?

Answer: You can access the counters through an installed, hardware-timed digital C Series module for applications involving quadrature encoders, PWM, event counting, pulse train generation, and period or frequency measurements.

 

Question: When I set the MTU to a value greater than 1500 on the cDAQ-9188 and hit save and reboot, the device is now unreachable. How can I fix this?

Answer: Trying to set the MTU to anything higher than 1500 on the NI Chassis will cause a communication failure. 1500 is the default setting. In order to restore communication to your chassis, press and hold the chassis reset button for 5 seconds or longer before releasing. Then, once you have re-established communication, be sure to set the MTU to 1500 or less.

 

Question: If the input power has dropouts, does the cDAQ-9188 need a backup battery?

Answer: Yes. If the 24VDC power goes out, then the chassis will lose communication and functionality.
