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

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

Q: 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?

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.

National Instruments cDAQ-9188 CompactDAQ Chassis

The cDAQ-9188 (Part Numbers: 781424-01, 782824-01, 190672G-01L ) 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 discharged rates, when a DAC changes starting with one voltage then onto the next. The biggest glitches happen when the most noteworthy piece of the DAC code changes. The user can construct a low-pass deglitching channel to evacuate 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 to advanced information (DI) or computerized yield (DO), if the C Series module being utilized permits such a setup. The user can gain advanced waveforms utilizing either parallel or serial computerized modules. The DI waveform securing FIFO stores the computerized tests. The NI cDAQ-9188 suspension 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. If the CompactDAQ Chassis gets a DI Sample Clock flag when the FIFO is full, it reports a flood blunder to the host programming. The NI device is equipped with 8 slots, 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 device is operated using the NI-DAQmx 9.2 driver software which is software packages/application development environment (ADEs) 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. in physical dimensions. It has a recommended operating temperature range of 20 °C to 55 °..Additional specifications for the NI cDAQ-9188 can be found in the manuals and user guides under the "Manuals & PDFs" tab.

While the cDAQ-9188 is no longer available from the manufacturer National Instruments (NI), the CompactDAQ Chassis will remain available in perpetuity with Apex Waves for both purchase and repair services!

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 back up battery?

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