  What PCMCIA or USB card that you would recommend for me?

  The PCI card that I used for the same project was the NI PCI-6221.

  6221 USB would correspond to my needs?

  Yes, that should be fine. You can always visit the DAQ hardware page to find the material for the acquisition of data appropriate for the needs of your project.

• Question about USB DAQ 6363

  Hi all,

  I'm new with LabView, currently, we plan to purchase NI DAQ USB 6363 to use the entry to read the value of the resistor, capacitor and a diode and use digital i/o to check the functionality of the analog shift register. I want to check if it is possible that NI DAQ USB 6363 to acquire communication RS232 function because I want to drive barcode interface on it. I'll use LabView to log the reading result of database (SQL, Access) to do some data analyzation. IM also confused on test bench OR what is the relationship between she and NI LabView? is this another software to install except for LabView?

  Thank you

  No, you do not connect an RS-232 device to the DAQ card. The RS-232 is connected to the pc. If your pc lacks a built-in port you can use a USB-> RS232 converter.

  TestStand is a test of the direction which runs tests written in several languages, including LabVIEW. He plans the tests determine the success/failure, record results, create reports, etc.

• help on select M Series DAQ card

  I have type resistive sensor in response to the impact (special potentiometer). I want to first test its dynamic property (degree of sensitivity to the hose stream) and then to design a simple circuit to trigger an output transistor with threadhold predetermined impact.

  I need a DAQ card to save data to a tension between the potentiometer, and my output transistor. I felt a 250 kech. / s, and 16-bit (even 12) entry is good, and no requirement for AO / DO.

  I prefer to use a laptop for the data analysis. My questions:

  1 should be a type USB DAQ for this application? If this isn't the case, I will return to a PCI card.

  2. If the USB is selectable, I fight with the (USB - 621 x) Bus-powered and non-powered bus (such as USB - 622 x); insulated and uninsulated. Note that none of the supplied external DAQ isolated function.  Among my preference: USB-6221, USB-6215 or USB-6211, which is more suitable for my data acquisition?

  Thank you all.

  Super! This morning, I decided to place the order with the USB-6221 and I am very happy that you assured me. Thank you, Khil.

  I acctually overlooked the phrase "single channel and aggregate" x 621. I have no doubt the rate of peripheral bus before but not found where was wrong. I also discovered that 6221 provides both sinking and DI I'll use two types of supply. Now I'm comfortable with the $ 200 more on externally powered one.

• Sampling frequency for the output of an acquisition of data USB-6211 card?

  Hello-

  I use a CGI CMOS FireWire camera to read an interference figure, then using a transformed of Fourier transform spectral interferometery (FTSI) phase recovery simple algorithm to detect the relative phase between the successive shots.  My camera has a linear 28 kHz scan rate, and I programmed my phase retrieval algorithm take ms ~0.7 (of a trigger of camera at the exit of the phase). I use the live signal to control a piezoelectric stack, by sending a voltage single sample to the analog output of a data USB-6211 acquisition card.

  Send this output voltage increases the time of my loop 4 m, I would really like to achieve a 1 kHz or better sampling rate. Is the problem with my DAQ card or with the processor in my computer? The DAQ cards of NOR can support these speeds?

  Thank you

  -Mike Chini

  Hey Mike,

  With USB, your loop rate will be around or under 1 kHz, even on the best of the systems. USB has a higher latency and less determism PCI and PCIe. You can get rates AO one much better sample on a PCI card, potentially a PCI-6221. We have a few HAVE points of reference for targets of RT for PCI, / AO in a loop, you should be able to get similar performance in Windows, but if you do a lot other treatments may suffer from your local loop rates.

  Hope this helps,

• many daq cards

  Hello

  I am moving forward with my project with the help of these forums and I try to not post on here asking for help, but I can't find an answer pretty clear to my last issue.

  I have several still model USB DAQ.  However, when writing my labview programs, they refer to Dev2.

  Is it possible through labview each poll for connected cards, or to group of NI Max DAQ devices so that they have the same virtual name?

  You can use a property DAQmx node for a list of all the features implemented. Each device must have a unique name.

  Hi ellisemuhire,

  If you can provide details on this type of functionality you need (inputs/outputs analog, digital input/output, etc.) and some details about the signals, you will work with I can recommend a USB DAQ product for you.  We have a wide range of products, so I'll need some information to make sure that I make the best recommendation for you.

• LabVIEW Application only works on a single DAQ card

  Hi all:

  I built an installer with DAQmx with card USB-6218. It worked very well on the target machine. But when I changed to another card USB-6218. It does not recognize the new card USB-6218. How to apply to recognize any DAQ card?

  Thank you

  Hi, TPL,.

  Take a look at This example of the community - it allows you to find the devices via the appropriate product name, rather than his alias of device.  The example could do with a few changes, but I think it will help you

  

• Trigger restarts on DAQ card

  Hello.

  I do data with a DAQ card acquisition, model USB-6251.  I need something like the sample VI "Acq & chart voltage-Int Clk - HW Trig Restarts.vi", except that I need the trigger for restart of much more effectively.  When I run that sample VI (and my own adaptation which is attached), I can't get that relaxing about 30 Hz rate and trigger that comes less than 30 ms of the previous, it is simply ignored.  I need to support rates up to 1 kHz trigger. Anyone has any ideas, or is there another way to go about it which will avoid this problem?

  Thank you

• LabVIEW code for two daq cards

  Hi all

  I'm reading the analog signals using the USB-6210 device and function DAQmx. How to write my code so it would work with the NI USB-6210 or USB-6218 since both a pinout similar devices.

  Thank you

  dp128

  Do not write anything to recognize a different DAQ card. It's as simple as that. They both have the same number of input channels, and they both have the same maximum sampling frequency. You will only need to worry if your program was out analog.

  When you install a sinlge on a pc data acquisition card, MAX lists it as dev1. If you do the same thing with a different DAQ card on another pc, it is listed here as dev1. As I said, there is no difference to explain.

• My old iphone 6s is completely broken, it does not or registry that it is connected when plugged into a computer. I'm able to recover photos from the SIM card with an adapter USB SIM card or through any other way?

  My old iphone 6s is completely broken, it does not or registry that it is connected when plugged into a computer. I'm able to recover photos from the SIM card with an adapter USB SIM card or through any other way? I also do not save anything with AllAccess, icloud, or through my computer as you would with a digital camera.

  The photos are not stored on the sims, sorry.

  You can always try the Recovery Mode, little to lose at this point. If it doesn't, I suggest taking it to an Apple Store for testing.

  Recovery mode:

  Turn off your iOS device.

  Plug charge cable to the computer only (not to the device yet).

  Open iTunes on your computer.

  Hold the button to power on your device and do not let go.

  Plug the cable into the device while keeping the power button.

  Wait for the computer to detect the device and wait that he eat.

  Restore as New first, then restore sauvegardΘ if you wish.

• External Usb Audio Card Popping and cracking sound with Satellite L500

  Greetings,

  My name is Boyan and I am from Bulgaria, and a year ago, I bought a laptop satellite l500 series (I can't tell which is exactly the model at the moment because my computer is not currently with me and my user manual, the only thing that is said is that it is for L505/L500/L500D / L505D.) But from memory I think it was the Satellite L500D-ST5506 which is currently not at my dispossal, because I gave him for repairs for the same problem that I say down below)

  The problem with my laptop, is that when I plug in a Usb Audio card in my laptop I have a crackling sound during live sound is played hollow map external speakers/headphones. I tried several sound cards and speakers/headpohnes which work perfectly well with other computers, including laptops, but the problem continues even when I use an external sound card to connect to the laptop not appearing in my laptop speakers/headphones.

  The problem is important only when the signal passes through an external audio card and it is very disruptive since I use my laptop to create music and I bought a sound card expenssive and speakers that can not be used with the laptop. I tried 3 types of sound cards:

  M-Audio Fast Track Pro

  BEHRINGER uca 222

  and a simple 3d audio usb audio card external and the problem persists.

  At first, I thought that the problem is software and I should install the new drivers, windows 7 automatically recognizes and installs the drivers for the devices and I have its in (but with the cracks and educated) so I tried using the official drivers sold for me with the sound cards, but without success: the problem was still there. I tried to find the new drivers of the sound cards on long official distributors and I downloaded it but the problem was still there. Then I tried to delete all the audio drivers on my computer and just use the external sound card for sound but this eighter helps force. I updated my drivers for my sound card build - in as well but again - no luck.

  After substantial thing frist I did when (2 weeks after I bought the laptop) was to contact the store where I bought my audio card and they said that the problem may be so eighter latency or high voltage of the laptop they advised me to try to reduce the latency of the parameters or to try and see if the problem persists if only my laptop running on battery power. I tried two things, and they did not help. Audio cards worked without problems on all the other computers I tried them but me. So they told me that the problem could not be audio cards.

  What I then was that I gave my laptop for the Distributor official of toshiba in my country so that they can solve my problem. What they told me, is that a problem with the version of windows which was preinstalled on my laptop and it was not compitable with the sound cards (which was bizzar survey because I tried them on the same windows and they worked, only on other computers). So I'm back from my laptop and passed under my Windows 7 Home Premium 64 bit operating system to Windows 7 Ultimate edition 64-bit and Windows 7 32-bit Ultimate edition on all versions, that's the problem: whenever I activate a low of passes of audio signal and Audio Usb card he heard cracks and educated. I even tried isntalling Windows XP, but the laptop want spesific SATA drivers for the Windows XP installation which although I found - they helped me install XP and I didn't go the BIOS of the computer to try to put a new and so on, because I'm not sure about that and I could lose my warranty so I said in the official repair shop for Toshiba in my city to put XP on my computer to solve the problem but they can't because they are not liscened to work with software that isn't a recipt for its purchase (which I did not because I bought my windows xp a long time ago and I lost the recipt)

  I gave her to get it repaired for the second time by telling them that the change of my operating system has not solved my problem and what they were doing was they changed the motherboard on my computer, indicating that the build in the device realtek audio on my computer is good enough to support a card usb audio or it may be broken and they change the whole motherboard because the generation of card is stuck, so they did it, but my problem has not been resolved. They told me that although I use and map external audio usb signal always going trough my only internal and I have to disable so I tried to disable this trough Control Panel, but this does not solve the problem and I don't have a BIOS option to disable my sound card build-in. Another thing I thought that maybe the problem is that two audio cards do not work on the same bitrate and Hertz so I put both cards to 16 bit 48000 Hz DVD quality (also tried the other options on the 3 cards that I have) but it's the same thing.

  They told me that it's just my luck and the construction of the sound card does not support this external sound cards and I would had been more careful when they choose to my laptop first.

  I couldn't accept this awnser for several reasons:

  (1) this sound card works on a lower version of windows and are supported by many older models of Realtek and a lot of old computers (one of them bought 2000! and my laptop is of 2010!)

  (2) the guys who were the apperantley of fixing problem don't go so deeply into my problem because they didn't know that in fact the problem was that only they knew that there is a problem with the audio card and the computer interact with them, they knew not that it cracks during the direct play the external audio card.

  (3) I can't accept the fact that Toshiba is manufacturing of models with maps audio chipset that cannot support a simple external Usb Audio card. It is totally unacceptable to me, and I sincerely hope that this is not the case!

  (4) they have tried my audiocards on another laptop of the same series, claiming that they have not at their dispossal at the moment so I'll go tomorrow at a local store and try the sound cards by myself on the same computer in the store.

  What I have now, it was that I gave my laptop for repair requesting a statement of the problem in wrtting with details of the problem so I can go to court or ask for a new laptop, but I'll be charged with little money because according to them there is no problem in the laptop and the problem is that my external sound cards are not compitable with the build in house chipset sound card. If I give my laptop for repair, and there is no hardware problem, I'll have to pay the money. I will do this, but I'm now crazy, because that does not solve my problem and I am wasting time and money.

  What I ask here is, if you can not help me solve my problem and advice me what to do to fix it, please give me the details of the chipset built in Driver sound card on my motherboard, so I can check if it is compitable with my external sound cards and contact the dealers of the sound card to ask them their opinion. Or if you can tell me what it is compitable with and what not, that would be great. Personally, I think this laptop should have no problem at all with a simple external usb running sound card, but I ask you, if you know something more about it.

  If a problem with the build in chipset then Toshiba is manufacturing (or at least sell) audiocards which are not in a normal standart but unfortunately I can not do nothing except complain to Toshiba and never treat whith such productgs more. Otherwise, if this is not true, then my laptop has a problem that is different and I have to go to court with the mans for mounting repair is not my laptop or do not give a new one when I guarantee will not fault of Toshiba and it will be in a way solve my problem.

  I hope that you understand how important it is for me and I hope I have fix the problem as soon as possible.

  P.S

  I want to say that I am familiar with grammar mistakes, that I did in the text below, and I would ask your excuses that I'm not a native speaker of English.

  Hi, I would just say that I had a similar failure although I wouldn't be surprised if she causing of yours, but you never have knowledge, my fault was the lid of my laptop [9 months], it contains the mic and when the lid has been in a certain angle cracks could be heard worse when I got my external sound card all the time it happened, luck, PS, it's a defective membrane [lid to the body] easily missed by engineer because he was the same angle you English is very good

• Error-200284 when using two daq cards

  I have an application written in Visual C++ that reads data out of a data capture with success card. However, now we want to add a second DAQ card, so we can increase the number of input channels. However, I have trouble getting the second card works fine. He continues to give the 200284 whenever I try to read the input data. I tried playing with the two loops in the same thread and with them in threads separated without result. Any ideas on what could happen?

  Thank you!

  Hello Kaladin,

  I'll take a look at the link below to see the cause of the error, but also some common things suggested to try.
