Le nom des ports de Ni USB-6259 afin de les implémenter en Cpp

bonjour je veux bien savoir le nom des Port Ni USB-6259 afin de parvenir à manipuler le materiel à l'aide de Programme en Langage C++. Merci de me répondre dans le plus bref des délais.

Alors déjà moi je n'ai mis aucun exemple, donc peux-tu me donner un lien, ou un fichier de l'exemple dont tu parles?
Ensuite, si ton exemple est fait pour du GPIB comme ton commentaire semble l'indiquer, tu es mal parti car l'USB-6259 est une carte d'acquisition DAQmx, elle n'utilise donc pas la communicaion GPIB, mais directement l'accès aux voies par les fonctionnalités du driver DAQmx.
Dis-nous quel est ton exemple, où le trouver, ou ce que tu cherches à faire et on pourra peut-être t'aider.
Sinon, tu vas dans le menu démarrer>>Tous les programmes>>National Instruments>>NI-DAQ. Tu y trouveras des guides d'utilisation du matériel USB, des guides pour comprendre ce qu'est le DAQ, et un guide pour le DAQ en langage textuel. Bonne lecture.

Problème tension de sortie des Ports Usb sous Lion

Bonjour, je viens d'acheter un Macbook Pro qui fonctionne sous Lion et je constate des problèmes sur la tension de sortie des ports USB.
Mon disque dur USB Freecom 500 GO ne monte pas ???
Par contre un autre disque dur Freecom en 320 GO monte sans soucis
J'ai fait l'essai avec le disque Freecom 500 GO sous un Imac sous Lion ... Il ne monte pas !
J'ai fait le même essai avec un Mac Mini sous Snow Leopard est le disque monte.
Dernier test, j'ai pris mon disque Freecom 500 GO que j'ai mis sur un Hub USB (alim. Ext.) et le disque monte sous Lion ??? !!!! ????
Est-ce que quelqu'un à le même problème que moi ou mieux... la solution
Merci

16 channels of data at 30kHz on the NI USB-6259 - is it possible?

Hello -- I would like to use the NI USB-6259 for electrophysiology. My application requires 16 channels of analog input digitized at 30kHz. This should be possible, as the listed aggregate digitization rate is 1MS/s. I've however run into several problems, all of which I believe may deal with how memory is handled in LabView (or maybe I'm just programming it wrong).
First off, if I pull in continuous voltage input using the DAQ assistant (DAQA) from anywhere from 5k to 30k samples at a time -- without any visualization -- things run alright. I record the data in binary format (TDMS) using the "Write to Measurement File (WTMF)" routine. However, I notice that the RAM used by LabView creeps up at a steady pace, roughly a megabyte every several seconds. This makes long-term recording unfeasible. Is there any way to avoid this? Basically I just have the DAQA and WTMF in a while loop that was automatically created when I set the acquisition mode to continuous.
Secondly, I would like to be able to visualize my data as I record it. If I set up 16 graphs -- one for each signal -- I need to raise the "Samples to Read" (STR) to 30k to ensure that the "Attempted to read samples that are no longer available" error [-200279]. This is annoying, as it makes the display look jerky, but is probably livable.
Now if I choose to display data in 16 charts rather than graphs (charts, as defined in LabView, display a bit of cumulative data along with the real-time signal), the amount of RAM used by LabView increases by several megabytes a second, regardless of whether or not I'm saving the data. After a short time, I get an "out of memory error".
Ideally I would like to be able to display 16 channels of 30kHz analog voltage data and save the data. As you see I'm having some level of trouble doing either of these things. Bare minimum requirements for my application would be to pull in the data with an STR of 30k, visualize the data in graphs, and save the data. Should this be possible in LabView 8.6 or 2009 (I use 8.6, but have tried these steps on the trial version of 2009 as well)? Even better, I would like to use an STR closer to 5k, and display the data in charts as it's saved. Should this be possible?
I'm using a reasonably powerful machine -- 32-bit Windows 7 with 3.24 gigs RAM, 2.4 GHz quad-core, etc.
Thanks

Hello!
I will admit right now that I can't stand any of the "assistants" and never use them. I don't like to have any part of my code invisible from me. Therefore, looking at your code gave me a headache. :-)
So, what I did is rewrite your code using the DAQ functions (basically what you'd see if you selected "Open Front Panel" on the DAQ assistant icon). You can go in and put the DAQ assistant back in if you so desire. This is just to give you an idea of the approach you should take. I'm grabbing 15000 points per loop iteration, just because I happen to like 500msec loop rates. You can tailor this number to your needs.
I have two parallel loops -- one collects the data and the other displays it on the front panel and writes it to a file. (I used the "Write waveform to file" function -- you can put your assistant back in there instead if you like.) The data is passed from the DAQ loop to the display loop using a queue. I use the "index array" function to select out the individual channels of data for display. I show 3 channels here, but you can easily expand that to accommodate all 16. You can also add your filtering, etc.
I am using a notifier to stop the two loops with a single button, or in case of an error. If "stop" is pressed, or an error occurs in the DAQ loop, a "T" value is sent to the notifier in the display loop (and that "T" value is used to stop the DAQ loop as well). That will cause the display loop to receive a "T" value, which will cause it to stop.
I don't have a 6259 on hand, so I simulated one in MAX. I didn't have a problem with the processor running at 100% -- on my clunky old laptop here, the processor typically showed ~40-50% usage.
I've added comments to the code to help you understand what I'm doing here. I hope this helps!
d
P.S. I have a question...how are you currently stopping your loop? You have "continuous samples" selected, and no stop button.

How do I connect my NI USB-6259 properly to SCXI?

I have
a NI USB-6259 DAQ Module
a SCXI-1001 Chassis
3 SCXI-1143 8 Channel Low Pass Filter Modules
and
a SCXI-1180 Front End Plate
I use a SH68-68-EPM Cable for Connecting the USB-6259(Connector 0) to a SCXI-1349.
Is it wise to use another Cable to connect Connector 1 of the USB-6529 to a SCXI-1349 mounted on the same chassis to get parallel operation?
Can I detect with my USB Module all 24(3x 8 Channel Lowpass) in Single Ended Operation with only one cable?
Thank you,
Alex

Hi Alex,
I'm sorry you had to wait for an answer for quite a long time.
To be honest, I don't really get your question.
One AI Input for the Cable on the USB 6259 has the range for 16 Signals.
So you can't send 24 Signals in one cable, as long as you don't add the signals in diferrent frequencies
and seperate them afterwards programatically..
But if you just want to get the Signal in the normal way you would need 2 cables for that.
Regards

Questions around calibration for USB-6259

Hi,
I
would like to do current measurements with the NI USB-6289 and NI USB-6259. I have several different boards to measure with low resistance resistors on them.
In my
understanding there are three calibration processes:
1) One done
by NI every two year
2) The automated
self calibration process done in the measurement and automation explorer.
3) And the
setup calibration done in the DAQ assistant where you must specify the
range used and calibrate the setup at several operating points.
Questions:
Can we
record the current calibration 3) into a file and reload it afterward by selecting the file with labview? (The
goal is to have one calibration file per device I want to measure)
Do we/can we
calibrate 3) for every range?
I am
not clear how to link the product specification accuracy with the DAQ
assistant calibration process: For instance what is the current drain
accuracy when using the 0.1V -01.V range and using a 1% 0.1ohm resistor
before and after DAQ assistant calibration? (same question for both NI USB-6289 and NI USB-6259).
Thanks in advance for your help
Best regards,
Jean-Marc

Hello,
I'm not an expert in calibration, but in regard to what you are trying to do I think you should take a look at this soft : Claibration Executive which allows you to manage calibration files.

Que tal Daniel;
El error 200609 normalmente sucede cuando el tamaño del buffer creado es muy pequeño, puedes realizar cambios programáticos en el buffer con los VIs avanzados de DAQ, te envío la liga a un documento que explica más a fondo como utilizarlo.

Using USB-6259 with LABVIEW 8.0

Hello,
I currently have Labview 8.0 and am trying to use the USB-6259 DAQ device. When trying to install the device I am told that the driver cannot be found. I have looked through the knowledge base, forums, and reference this document: Device Drivers
I have downloaded DAQ-MX 8.8 has shown by the previous link, but that version of DAQ-MX does not support Labview 8.0. I am hoping someone knows a way I can make my version of Labview and this device work together.
Thank you in advance...

Comparing DAQ readings with a meter can be tricky for a lot of reasons. To begin with, what is your sample rate and period? Because the signal you're reading is an AC source it's level is constantly varying (at a 400 Hz rate ). Hence, you need to sample enough of a waveform that you can calculate the appropriate AC parameter (peak-to-peak, RMS, or what have you).
Also remember that meters always have a certain amount of built-in hysteresis or dampening to make the output easier to read.

Editer le nom des axes d'un graphe

Bonjours,
J'aimerais laisser la possibilité à un utilisateur de changer manuellement le nom des axes d'un graphe XY sous labview.
En effet j'ai remarquer qu'il étais possible de changer les échelle (min et max) simplement en cliquant dessus et en tapant la valeur voulue. Est-il possible de faire la même chose avec le nom de l'axe?
En gros j'aimerais que l'utilisateur puisse changer cette propriété directement depuis le graphe: Yscale.Namelbl.text
Cordialement
Sébastien Kuenlin
Résolu !
Accéder à la solution.

Bonjour,
Non, cela n'est pas possible. Par contre il est possible de modifier les noms par programmation. Il est donc possible de modifier le nom des axes en fonction des data représentées, ou d'ajouter un peu de code pour "donner" la main à l'utilisateur final. Cela peut par exemple être un bouton qui ouvre une boite de dialogue dans laquelle on pourra renseigner le nom des axes.

Comment personnaliser les noms des balises xml

Bonjour à tous,
Je cherche à utiliser les fonctions XML de labview2011 (genre Redresser à partir d'XML) afin d'extraire des valeurs différents champs. Seulement j'ai besoin de personaliser le nom des balises xml afin de lire mon fichier correctement. Par exemple j'aimerai avoir ce résultat de type à partir d'un cluster :
<MyField>
<Name>MyName</Name>
<NumElts>1</NumElts>
<MyField2>
<Name>Document</Name>
<MyField3></MyField3>
</MyField2>
</MyField>
Mais voici ce que j'obtiens :
<Cluster>
<Name>MyName</Name>
<NumElts>1</NumElts>
<String>
<Name>Document</Name>
<Val></Val>
</String>
</Cluster>
Comment remplacer les noms des balises <Cluster> <String> etc.. ?
Merci d'avance
James

USB-6259 to capture the current waveforms

Hi all,
I am pretty new to LabView and data aquisition. Sorry to bother you all. I have a question:
"Can I use the USB-6259 DAQ device to capture the current waveform of electrical appliances e.g. electric kettle using current probes????? If yes, could you be very kind to guide me in this regard???"
Thanking in anticipation.
Best regards,
Haroon

Yes, you can do that. You need to do the following:
1. Put a shunt resistor (1ohm, high precision, high wattage) in series with your application.
2. Use one of the Analog input from your DAQ to measure the voltage drop across the shunt, and this will be your current waveform, since the resistor has 1 ohm.
Things to watch out for:
1. Power rating on shunt: make sure your shunt can handle the power.
2. Noise: you may need some filtering circuitry to get rid of the signal noise. If you are comforable with digital filtering, you can use some of the filtering function in LabVIEW.
3. Level at AI: maybe very low, since there are little drop across the shunt. If you don't mind a larger voltage drop, you can increase the value of the shunt to increase the level; if you just want to look at the pulse shape. Or, you can put an amplifying circuit for a little boost before you feel the signal to AI.

A dv9000. Which port is the usb 2.0?

My Device Manager says that out of my four usb ports, three are usb 1.0 and one is an enhanced usb 2.0 speed, but there are no markings, or any way to tell which is which. Does anyone know how to tell? Thanks in advance..

There's no number beside Service tag
Incidentally, I called HP tech support with this same question and I was told that, because my warranty had expired, I'd have to purchase a service contract to "UNLOCK" this information.
There's nothing listed in the user guide. Imagine!! I have to pay for information pertaining to my computer specs. I wasn't asking for him to fix it...just give me specs that should be in the user guide.
That's enough reason to shop at another place for my next computer.
I'm not the good representive I used to be for HP.
Thank you for whatever help you can give me on this matter.
