Hi .
I'm new to USB 6000.
I'd like to know if I may use the P0.3 output (5V) as a voltage source (like Arduino board) and, if yes, wich is the max current allowed through it.
Thanks in advance

PCI-6259 voltage measurement issue
Hello,
This is my first topic on this forum and I had to do this as I'm already desperate with an issue regarding the V measurement.
I'm using the PCI-6259 and I'm trying to measure a voltage between 2 and 9V on Dev1/ai0. I use SCB-68A and the wires are connected at pins 68 (+) and 34 (-). The problem is that after 1-2 minutes of measuring correctly (photo NI MAX1) it start to measure like a square signal (photo NI MAX 2 and 3). After few more minutes it stabilize at 10.6V and it doesn't move even if I disconnect the PS. The only way how i can measure again is by restarting the PC. First I've seen this in labview but also in NI MAX is doing the same. If I move to another channel it's doing the same after some minutes. I did ran a self-test and a self calibration, both ok but made no difference.
What have I done wrong and what exactly is happening?
Thank you!

Data Logging with Four NI 9211 Modules (16 Thermocouples)
I am fairly new to LabVIEW and I only know the basics of it. I am trying to log temperatures of different areas using 16 thermocouples (with four NI 9211 modules) for about four hours. I need help setting up a VI to do this project.
Can someone please advice me on which functions should I use?
Sample rate? Number of samples?

Issue with connecting NI-MAX and Crio-9025
When trying to setup a virtual channel through NI-MAX I'm running in to the issue where the chassis is listed under Remote Systems and thus I can not go though the DATA Neighbor to set up my channel. Does anyone know how to either set up a virtual channel in remote systems or how I can get the Crio to be listed under My System.

Omega Pressure Transducer troubleshoot needed
Hi, I am new to Labview and NI-DAQ device. I want to connect an OMEGA differential pressure transducer on a small pipe tube and acquire a voltage signal through DAQ assistant. The pressure transducer was provided calibrated by the company. The pressure transducer has a linear voltage output 0-10 VDC and the pressure range is 0-2.5 KPa. This means to get corresponding pressure signal I simply have to multiply the voltage signal by 0.25. The pressure transducer has 3 wires; black, white and red. The transducer requires 24 VDC excitation and I have connected the black wire to the –ve and red wire to the +ve of the 24 VDC power supply. I have connected the white wire to pin #31 of NI USB-6211. Additionally I have also connected –ve of the power supply to pin# 32.
Now when I use the DAQ assistant to acquire a signal on my computer and use a multimeter on pins 31 and 32 the voltage values do not match. Please if you could tell me what I am doing wrong here.
Thank you

NiDAQmx with MSVC2017 and Qt 5.10 gives "Application was unable to start correctly (0xc0000142)"
Hi,
I'm working on using the NiDAQmx ANSI C libraries inside of a Qt application. I copied the 64bit NIDAQmx.lib file and all of the headers from National Instruments\Shared\ExternalCompilerSupport\C into my Qt project directory, modified the .pro file to point to them, and am able to compile and link without errors. However, the application crashes immediately with the 0xc0000142 error. The modified section of my .pro file is below, with NiSDK containing all libraries and headers from ExternalCompilerSupport.
LIBS += -L$$PWD/NiSDK -lNIDAQmx
INCLUDEPATH += $$PWD/NiSDK
DEPENDPATH += $$PWD/NiSDK
I've also tried eliminating my project-local copy of the library and headers, and instead pointing the .pro file to look directly in the ExternalCompilerSupport subdirectories. This also compiled fine, but crashed with the same error.
Are there additional DLL's I need to make Qt aware of during the build?
Thank you,
Tom

NI PCIe 6351 X-Series card not detected on computer system, not seen
Hello Community,
sorry for asking questions towards an ordinary installation problem according NI PCIe 6351 X-Series card.
I purchased 2 identically cards and they are not seen in the device manager or MAX on 2 different Windows-7-PC.
The first PC is a Lenovo Workstation E31 manufactured around 2012 with latest BIOS installed.
The other PC is Fujitsu Siemens.
Both PC do not show up the card in device manager with NI-DAQmx 16 drivers installed.
After several trials and BIOS-adjustments one card showed up once or twice in device manager of windows with an Asterix,
saying "Unable to start the device". Later they disappeared again.
We tried x1 and x16-slot. Both same behaivor.
The temporarilly showing up was in the x16-slot of the Fujitsu Siemens PC.
Is there a known issue about detection problems on X-Series cards?
Any known solutions on the forum, though i was not able to find any for me.
Regards from Germany.

Do I need DAQmx Timing in my DAQ solution?
Hi all,
I use my USB-6000 I/O to acquire two analog signals coming from a temperature and humidity sensor. I continuously check if the temperature is above the user limit and I use an indicator to show this overheating.
The SubVI called multiple_sensors.vi acquires the two analog signals but I do not use the DAQmx Timing.vi to do that because I only need one sample of both signals each time I run the SubVI and this happens when the state "Acquisition" is active in the state machine.
The VI works fine but I wonder if I should use the DAQmx Timing.vi in my DAQ because it is always used in the NI DAQmx solutions.
Can you tell me if I should use the DAQmx Timing in my DAQ?
Thank You!

Measurement and Automation Explorer
I have a PC that won't run MAX. Opening MAX gives me the following error:
The CniDMFuiProvider::Initialize plug-in caused an exception in the CmxExecutionThreadPool:
oWorkNonUI function in the MAX process.
See this file for details:
C:\ProgramData\National Instruments\MAX\Logs\MAX\af7d2d2a-3244-48ad-993b-067327b12a1e\8537cbf3-7f06-4679-bc57-158048e40089.dmp
I attached the dump file but .dmp files aren't supported so I zipped it.
This locks up MAX and the process must be killed. ( Windows 7 64-bit )
I have installed, uninstalled ( all NI software ), and reinstalled NI-VISA, NI-DAQmx, NI-MAX and that didn't help. I reset the configuration with the reset tool per another post I found and restarted the machine. No help.
I repaired NI MAX and restarted. No help.
I have installed NI SW for 15 years and never encountered this and since I can't uninstall, reinstall and go I searched the forums for help. I didn't find a solution to this issue other than the repair and/or resetting of the configuration.
I'd appreciate any suggestions on how to fix this. Thanks.

Multifunction NI-USB 6210 vs Isolated Multifunction NI USB-6218
Hi, we have both NI-USB 6210 and NI-USB 6218. We are mainly using the 6218 but we need to lend out either of the 2, I'd like to know if there would be much difference in performance between the two? I already looked at the specs and aside from difference in port selection, one thing I notices is the printed "Isolated Multifunction" in NI USB-6218 and only "Multifunction" in the 6210. Port selection is not an issue and since all the other parameters are basically the same for the two, I would like to know if an isolated would be much different from non-isolated multifunction daq.
P.S. I'm not really an electronics major but I do use these devices quite frequently so if you could explain it simpler it would be better. thanks in advance.

NI 9219 and Load Cell Compatibility/Functionality Question
Hey Everyone,
I am a biologist and I wish I took far more courses in engineering and physics as I am finding myself building more and more unique things for my research.
With that said, I need a little help and I apologize for the potential simplicity of this but I want to make sure I am taking the right steps before I purchase. I came across a youtube video by National Instruments (https://www.youtube.com/watch?v=MQTniyInnsI) today and it highlights a project that I am very interested in pursuing. More specifically, I am looking to build a bite force meter and therefore, I was looking to use the LabView Software, paired with the NI 9219 DAQ, and a load cell (preferably the Honeywell 060-0239-08 Load Cell paired with aluminum plates as it can register up to 10,000lbs of force). Is the process as simple as connecting all the equipment or will coding, calibration, or anything else be required? I am looking for a relatively inexpensive option and these materials are currently feasible for our budget but before I jump in with both feet, I was hoping someone could tell me that the process just isn't the simple...but I am hoping it is.
Thanks so much and I look forward to your reply.
Kind Regards,
Craig

digital 5V show sawtooth noise at 200Hz and 100mV
PC: HP z230, windows 10 64 bit
NI card: pcie-6363
All digital lines, including digital 5V output show a sawtooth noise, p2p 100mV, 5mS period, as shown in the attached picture.
Other information:
- on the same PC, another NI card PCI-6733 doesn't have the same noise
- switching to another cable made no difference
- switching to another identical PCIe-6363 card made no difference
Question,
Is this a problem for all the PCIe-6363 cards?

Multi IP MAX on Windows 10
HI all,
I'm attempting to get my cDAQ 9189 up and running on my work network. How do I force MAX and LV to use a secondary IP on my computer to connect to my device ?
Due to security we have two subnets, one for users, and one for IP addressable devices like the 9189. To access both device our computers are "Multi homed", or one network adaptor is assigned two IP addresses. A 168.X.X.X is used for our internal network, and a 10.10.X.X for the device network. The 168.X.X.X must have priority as it is used for all non NI applications. Currently both MAX and LV only recognize the 168.X.X.X network. How do I force MAX and LV to use the 10.10.X.X network?
Here are the details:
Host computer is running Windows 10, 64 bit, and has dual IP's 168.X.X.X and 10.10.X.X
All host addresses are static.
cDAQ 9189 address is configured to static, and is on the 10.10.X.X subnet.
All Subnet Masks are properly configured.
No firewalls exist on the 10.10.X.X network.
I can ping the cDAQ from the host and get a response.
LV and MAX are up to date, and 64 bit.
Thanks in Advance,
- M.

Wiring Futek Torque Sensor to NI 9205
I took over on a project building a materials testing machine, and the previous builder left me with a Futek TRS705 torque sensor and a NI 9205 DAQ board. He claims that he bought them specifically to be wired together. I've found the wiring diagrams for the sensor and the DAQ board individually, but I cannot figure out how to put the two together. I've wired all the grounds to the COM, but I am not sure how to properly wire the power and the signals. Are the power and signal a differential pair that should be wired alongside each other (AI+ and AI-)? My experience with data acquisition wiring is pretty limited, so any help is appreciated.
