Expert Insights for the cDAQ-9185

"The cDAQ-9185 is a CompactDAQ chassis that is perfect for small remote measurement systems. It has ethernet connectivity, timing synchronization, and four 32-bit counters. It is able to use TSN for measurements over long distances. With 2 ethernet ports, you can have redundant network connectivity, or combine chassis in the same system. It is perfect for a growing or changing system."

National Instruments cDAQ-9185 CompactDAQ Chassis

The cDAQ-9185 (Part Numbers: 785064-01, 786473-01, 787929-01) is a CompactDAQ Chassis. With this model, the user can introduce a thermocouple module by an accelerometer estimation module and gain both at various rates. The NI cDAQ-9185 Chassis has numerous simple information timing motors, which allows the user to gather the majority of their simple info modules in up to three arrangements of modules. These sets, known as undertakings, would all be able to keep running at various rates if each has its own specific motor planning in the backplane undercarriage. This reduces the need to demolish bring down speed information from the higher-speed information.

To exploit the 1,000 Mbit/s of data transmission on a Gigabit Ethernet interface, this NI CompactDAQ Chassis actualizes a TCP/IP network protocol. With this innovation, C Series modules such as the NI-9223 can persistently gain up to 1 MS/s of synchronous 16-bit information on all four channels. Besides, various NI CompactDAQ undercarriages can have a similar Gigabit Ethernet organized for appropriated, high-channel-count frameworks. The device has a timing accuracy of 50 ppm of sample rate.

Utilizing a modern programming design, the NI-DAQmx driver programming allows for buffered operations. This operation type is when data first moves from a host buffer to an onboard FIFO before being written to modules for analog output. For digital input, the data moves from the onboard FIFO to a PC buffer. In the meantime, the driver screens the condition of the system to modify for startling deferrals or transitory intrusions. The greater part of this is preoccupied from the client, so the user can center on the estimation application and not the system. The device can be programmed using LabVIEW or LabWindows/CVI.

The NI device weighs 23.3 oz, and measures 7.01 x 3.47 x 2.52 in. in physical dimensions. It has a recommended operating temperature range of -40 °C to 70 °C, a storage temperature range of -40 °C to 85 °C, non-condensing operating and storage humidity ranges of 10% to 90% RH and 5% to 95% RH respectively, and random and sinusoidal operating vibrations of 5 grms and 5 g respectively–all at a frequency range of 10 to 500 Hz. More information about the cDAQ-9185 can be found in the datasheets and manuals of the "Manuals & PDFs" tab.

National Instruments cDAQ-9185 Frequently Asked Questions

Question: Why are there two different part numbers for the NI cDAQ-9185?

Answer: Part number 785064-01 is not conformal coated, while part number 786473-01 is conformal coated.

Question: When I run the NI cDAQ-9185 in Test Panels in MAX, I get an Error 209836 - "the devices in your task cannot be synchronized." What should I do?

Answer: This may be because there are no available synchronization mechanisms between the devices. Make sure that all of your drivers are updated.

Question: Is the NI cDAQ-9185 CompactDAQ Chassis supported in Linux?

Answer: No, this Chassis is not supported in Linux.

Question: How many ethernet ports are available on the cDAQ-9185?

Answer: The cDAQ chassis is equipped with 2 ethernet ports.

Question: Why can’t I see the NI cDAQ-9185 when it’s connected via the network? I can see it when it’s connected through MAX but not when connected through the network.

Answer: Your cDAQ-9185 may not be able to be seen because it is TSN (Time Sensitive Network) enabled. TSN uses the Rapid Spanning Tree Protocol (RSTP) to create a loopless network, which is not compatible with some network settings. If it is not possible to configure your network differently, you could consider a non-TSN cDAQ chassis, such as the cDAQ-9184 or cDAQ-9188.

Question: Why can't I see the CompactDAQ Chassis in LabVIEW?

Answer: The cDAQ-9185 does not have its own controller, so it can not be added to a LabVIEW project- instead, you will be able to access it with DAQmx API.
