• Tension AC with DAQ card analog interface

  Dear all

  My sensor gives the alternative of 200mV analog signal tensions. Can I get these tensions on LabVIEW using the NI 6281 DAQ board. (I've already acquired 100mV DC analog voltage signal which came from another sensor using the same card and I use port 66 and 33 for this signal). Can I adopt the same procedure and using the same ports?

  Waiting for your response.

  Kind regards

  Yes.  Since this is an alternating signal, simply measure at a high enough frequency of acquisition to represent your signal.

• Analog input base changes during digital output in parallel

  Hi all

  We use a USB DAQ 6008 to run a simple system. AI6 is connected to a motion sensor; digital outputs control a pump. We noticed that if we read AI6 without performiong of additional tasks, the baseline is ~0.17V and when movement is detected it comes down to 0.13V. However, if we read AI6 while performing outputs digital at the same time, the base line comes down to ~0.14V and when activated he descends to ~0.1V, i.e. the line base modified by 0.03. We do something wrong or is this expected behavior?

  Thank you

  Danielle

  Danielle,

  You may have a ground loop. If the current of the pump or even digital control for the pump through the Earth wire similarly that the signal of the motion sensor, the voltage drop in the common driver because of the current pump could cause an effect like you report.

• Module adaptation NOR - 6581 FlexRIO - Can one single port of IO have a few lines of channel defined as inputs and some defined as outputs?

  Hello

  I use a 6581 with 7965R FlexRIO FPGA module adaptation module. E/s/Port CLIP Module allows to configure a port as an input or output, but I would first of all a line of a port as an exit channel and the remaining lines of seven channels as inputs, it is possible to do?

  Thank you

  Maurice.

  Hello Maurice.

  The 6581 adaptation module can only change direction based on port (not on a basis of individual line).  This can be seen in the specs here.  There are other modules of digital adapter that support by the steering control of channels such as the NOR 6583.  The NI 6583 35 single ended e/s and the input/output LVDS (or mLVDS).

• a speed of read/write DAQ card mode change will reach 200K

  HEY, man,

  I have a project needs to test two points I name them point A and point B, the first time, I should point A 5V DC input, voltage inductive test point B, sencodly, give point B 5V DC input and inductive point test output voltage, this means and two analog ports must read and write sharing mode , and the test speed must be 100 KB, if I have a 200 KB data acquisition card, can the speed of read/write mode change reach 100 KB for an analog port? or, please give your suggest for my this kind of situation, thank you.

  Hi API,.

  I see that you are trying to measure voltages using a single channel at a time on a data acquisition card.

  Unfortunately, you cannot change the inputs to the outputs or vice versa on a map of data acquisition, they are static.

  What I recommend is either using a switch like this: http://sine.ni.com/nips/cds/view/p/lang/en/nid/207130 where you will need a high chassis.

  Or, having four channels, 2 inputs and 2 outputs and try to measure it. You should have the necessary speed as well.

  If you have any other questions, I'd be happy to answer.

  Thank you very much

• Synchronization output analog and an entry for imaging

  Hi all

  I'm stuck in my higher studies project and really need help. I tested an imaging system, where one uses two mirrors MEMS to analyze the sample and a tube set (PMT) allows to acquire voltage signals and translate them into images of scanning laser.

  I use the same DAQ card for input and analog output. The DAQ card sends features X and Y of the MEMS mirrors so that the reason for scanning 2D starts left to right and up and down.

  Scanning rate: 131500 pixels per second.

  Size: 1170 by line, 514 ranks in total pixels.

  Thus, the mirror will scan 601 380 pixels per image, which takes approximately 4.57 seconds to complete. I almost finished this part in LABVIEW.

  However, only a part of the scanned pixels are read by the PMT. We want to get an image of 512 x 512 pixels. For example, the PMT works like this:

  (1) the sampling rate is also 131500.

  (2) skip the first row.

  (3) starting at the second row, the PMT will jump the first 329 pixels, read in the next 512 pixels and skip the rest 329 pixels again. Then, it moves to the next line.

  (4) jump the last row.

  My approach in the plate sequence

  (1) ignore the signals of all 841 (1170-329 = 841).

  (2) create a loop for, run 512 times.

  (3) in each loop, first jumping 658 signals (329 x 2), then read the signals then 512 MB.

  (4) wait 1499 pixels left to complete the digitization (1170 + 329).

  Problem

  The mirror and PMT must start and finish at the same time running. However, when I run my VI for the analog input and create the image on the Panel, it takes 5.7 seconds to complete, which means that they are not at all synchronize. It seems that there is some unexpected time in the loop for, but I don't know how to change the code to meet the requirement of calendar.

  Please see the attached VI. Any help is greatly appreciated.

  My approach in the plate sequence

  (4) wait 1499 pixels left to complete the digitization (1170 + 329).

  Consider this: add up all these pixels, both those you want to record and those you want to ignore.

  If I read you right, that would be:

  841 + 512 * (658 + 512) + 1499

  Regardless of this number, set up a task that many samples and record the whole bloody thing.  Let the time of equipment for you.

  Then, AFTER that data are in hand, pass by and throw the first 841 points, then for each loop, throw away 658 and keep 512... etc.

  IOW, let the MATERIAL which made the better material: precise timing.

  Let the SOFTWARE do what does best software: weird logic.

• How to synchronize two cards NI9215 DAQmx?

  Hello

  I use two NI9215 DAQmx cards (analog inputs sample simultaneous 4ch) in a cDAQ-9174 chassis type.

  Because I need to acquire 8 channels at the same time, I have two NI9215 cards.

  My question is how to configure these cards to be synchronized?

  I use LabVIEW2009 SP1 dev Suite.

  Thanks for the replies!

  One of the nice things about CompactDAQ is that you can put multiple modules of the same time (analog, digital, etc.) in the same spot and they are automatically synchronized.  Then, to synchronize the two modules, create an analog input task and reference strings like "cDAQ1Mod1 / ai0:3, cDAQ1Mod2 / ai0:3.  It automatically synchronizes the two modules together.

  Hi there @LeoOfMars
  
  Welcome to the Forums of HP Support! It's a good place to find the help you need, so many other users, the HP experts and other members of the support staff. I understand that you are looking to find out if a video card is compatible with your information system. I'm happy to help you with that.

  The main reasons to be sure of are normally feeding you, special (to THE) cable power supply for the graphics card, on the motherboard compatible expansion slot, the drivers for your operating system, another thing to know is the physical size of the map, for moments of cases.

  Looking at the specs of your system and the motherboard by default, I listed the type of slot of power and expansion.

  HP Pavilion Elite e9180t Desktop PC product specifications and configurable Options

  Output power of power: 460 Watt

  HP and Compaq desktop PC - specifications of the motherboard, IPMTB-TK (Truckee)

  Two graphics PCI Express 2.0 x 16 (for graphics cards)

  Go to the video card you are looking at:

  GTX 780 3072 MB GDDR5 PCI-E 3.0 OC Custom cooled graphics card

  Input power: 1 x 8-pin auxiliary input aux input 1 x 6-pin
  Bus type: PCI-Express 3.0 16 x
  
  System requirements:
  Mother compatible PCI Express with a slot of chart double-width x 16
  Power 600W minimum (with a minimum of 12V current rating of 42A) 3
  300 MB of available disk space
  2 GB of memory system (4 GB or more recommended)
  Microsoft Windows 8, Windows 7, Windows Vista, or Windows XP Operating System (32 or 64-bit)
  DVD-ROM drive or Internet connection for installation
  DVI, HDMI, DisplayPort or VGA compatible monitor

  So on a quick inspection of both devices there are three problems, so this card will not work on your motherboard or with the current power.

  I hope this helps.

• Satellite Pro A120 - impossible to get a PCMCIA card work

  OK, I have a problem with cardbus (xp SP2) of my Satellite Pro A120.

  I use the cardbus slot to add conections firewire via an IEEE 1394 cardbus card and have been doing this for a long time. The other night, my computer came into hibernation with the card still in the slot and still in use, and when I tried to use it the next day, the card wasn't working at all.
  So I thought that had died on me and has brought another, this one to be exact [http://www.newegg.com/Product/Product.aspx?Item=N82E16839314003].

  When I plug the new card into the slot, windows starts the installation add something new but can't find the driver, nothing on the CD provided, and it does not conect to windows update to find an ethier. Thus, the new card does not work and do not settle, it appears just with! next to pci device.

  I have searched all over the internet to find the driver, read the manual etc. I even did a fresh install of windows so that he could find the drivers but nope.
  The only thing I can think is the slot does not except 32-bit cardbus, but in my manual it says this:

  «The computer is equipted with a pc card slot which can accomedate type II card.» Any pc card that meets the standards of the industry can be installed.

• Digital and analog generation and acquisition using USB-6251

  Hi all

  I have to actually synchronize a 6251, USB and USB 6366 Board. I have a vi, which is good that now I am able to use the 6366 as the master and as slave 6251, attached tie. The master generates a digital trigger for (generation synchronization) pulse and the acquisition of the signals on both cards, analog signal ramp and acquires signals. The slave acquires only a series of signals after outbreak.

  I want to have the 6251 as master and as slave 6366. The vi attached the other way around as I mentioned above. When I try to use the 6251 as the master, I get an error asking me to specify the clock source (I did the material and some changes in the program as well, as export properly 6251 at 6366 clock).

  Thank you

• Read analog output channel value internally

  According to this you can read the values of analog output of return without having to physically connect the wires.

  By using the technique described in the example given (DAQmx_Read_Output_Internal_Channels.vi) I'm reading a current area of OCCUPANCY on my compactDAQ cDAQ-9174 with a module of analog output current OR-9265.

  The output channel is created in MAX and my vi can write values to him without problems

  But when I try to create an analog input channel to read the output, an error occurs.

  What I am doing wrong?

  This is not supported by my hardware?

  Or is the example given in the above incorrect link?

  The example is 10 years old. Maybe, it does not work in LV2013.

  

  

  Hi Jocker,

  The link was not attached to your message, but I guess that's it: http://digital.ni.com/public.nsf/allkb/CB86B3B174763C3E86256FFD007A2511 as there the example of vi you mention.

  The error you are getting is due to the use of the channel for analog output and trying to configure the task as a task of entry. You must use _aoX_vs_aognd as the channel of the task rather than on the output channel. This compares to the ground for the analog output values.

  The NI 9265 is not on the list of the C Series modules that have internal channels:

  http://zone.NI.com/reference/en-XX/help/370466W-01/mxdevconsid/9211interchan/#GUID-E13ADE46-5CB8-491...

  So I guess that the module is not able to compare its output to ground. He would appear in the dropdown of the channel names if available.

• 1078 PXI trigering internal between cards

  Hi all

  I want to use the internal chassis SMU 1078 trigering. I read online about the internal trigers PXI and in my case I have PXI_Trig0 to PXI_Trig7. my setup is this I use a card PXI 6535 DIO card analog 2 and 6115 slot into the Groove 4. I would like to generate an internal trigger using the back of the chassis PXIe1078 when I want to map PXI 6115 to begin to acquire data. Currently I use the Triger from outside. The idea is to have an internal trigger in the rear chassis plan to remove the need for an external trigger.

  A little on the process flow I send data digital 6535 card to a sensor, and as soon as I send this data that I would send the trig map 6115 through the back plane of start to acquire. I'm still not able to understand the programming part how to use the trigger to the background using labview.

• How to count the pulses with digital input on 6351

  Hi all experts in Labview,.

  I just got my USB x series 6351 and it works fine, but I certainly lack of labview skills to use it to its full potential.

  I would like to read digital pulses with several digital inputs and count the number of pulses each T interval in time. All impulses that I entered on any edge of the clock are not synchronized and can occur at random times during the tests. Basically I have an oscillator of square waves can I modulate the frequency. I don't want to use the meter as inputs as I'm limited to only 2 entries (if I use the option 2 input meter for metering of pulses or frequency). The input frequency can range from 0-1 kHz and goes 0 - 3V. So not too fast, and I shouldn't make too many mistakes trying to get the count of pulses and then back out the frequency in accordance with article ni.com on counters.

  I would like to read the 8 digital input channels and get the number of impulses for each channel. I searched high and low for help online but can't find examples that have been useful. Anyone have any ideas on how to go or direct me to a resource? Thank you very much in advance!

  Are you worried about getting the number as a physical operation timed?  It would be nice to acquire a digital waveform and then postprocess on it to detect how many events took place?  I've attached an example that shows how you can accomplish this. It reads a digital waveform and then uses a detection of crete VI to determine how many pulses occurred. Should be a few adjustments to your particular signal.  The VI I use seems to count events twice (probably count each edge), so counting it gives should be reduced by half in order to work.

• Difficult to use the outputs analog to generate a predetermined file

  Hey all,.

  I tried to produce a file predetermined to a 1 kHz on my USB 6343 Multifunction DAQ analog output channel.

  Here are the questions I have am experiencing:

  1: output file so fast my o'scope cannot even pick it up.

  2: when you try to stop the output it almost freezes.

  3: my graphical waveform data and the plot does not update with the data that have been read.

  If someone wants to tackle one or more of these questions, I would be very appreciatve.

  Thank you

  I tried to adjust the "DAQmx Configure Ouput buffer" but it really doesn't seem to have much effect. Do you think I should try a loop For to pick an amount predetermined points then output them quickly?

  It's weird.  So I don't generally need to use the function of output buffer configuration you have.  If you look at using the Subvi DAQmx Timing just after it, you will see the samples per channel will help determine the size of the buffer.  You might want to try do not use the function of buffer output set at all, not that I don't know if that will fix it or not.

• ThinkCentre M51 SFF 8104 - PCI graphics card

  I'm hoping to add a second graphics card for my Ultra small, M51, which has only a 32-bit PCI (not PCIe) slot. While I am aware that much slower speed of the PCI in the PCIe (or even AGP) bus stop from playing any modern (say > 2005) games, I'm not really that interested in 3D performance. The main reason I want the additional card is so I can use an output for my projector (not HD) and maybe even plug a third monitor integrated card (Intel GMA 900) - if I'm not forced to disable this. Is this likely to work? Has anyone here successfully added a PCI graphics card to a ThinkCentre, or any other computer with an Intel 915GV (* blech *) motherboard chipset?

  I know that some people suggest you need a bigger power supply for some of the fastest PCI cards, but I'm not sure about this. For a card that will be classified as PCI, it must be within the electrical specifications for the PCI bus, which includes the voltage and current, no? If I'm wrong about this, I would be happy to settle for something more modest, as long as it provides DVI output, some 3D acceleration, but also MPEG decompression. Any input on this very appreciated!

  Another restriction could be the space required for the card, the case accepts a PCI full-height, half-length, but will be a little better maybe with a card low profile to leave a little more room for air circulation. I certainly don't think that a passively cooled card would work as there is virtually no room for air circulation. And even with an actively cooled card, I recognize that I might need to add a few extra air holes.

  Why go through all this trouble? Well, I love the little ThinkCentre Ultra compact. The case is very well built, it is very pretty in this industrial kind so that IBM had so well - and it's very nice and quiet too (despite the P4HT Prescott). Gigabit LAN, 6 USB, 3.5 "HDD bay (got a 1 TB drive is and the fact that I can use my laptop DVD burner into the UltraBay slot are all nice positives.) I'm not a fan of large desktop computers and can not afford a mini-ITX with PCIe system...

  For any help or suggestion very appreciated!

  P.S. PCI graphics cards I've been looking at are GeForce 8400 GS Sparkle and 9400 GT cards as well as Radeon X 1300 VisionTek and X 1550. And then there's the new ATI Radeon HD 2400 PRO too!

  Update: I have now installed a graphics PowerColor HD 2400 Pro PCI in my system. I had to replace the passive radiator with a combination of radiator & fan (the card has holes of standard editing for it), because there was not enough room for it. Also, the case is so narrow that there is no way the airflow around the PCI slot would have been sufficient to adequately cool the GPU. Unfortunately I could not find the drivers for the use of this card under Windows 2000 (my OS preferred) so I'm stuck with XP - but the card works fine and I can get today with the built in Intel GMA chip, giving me three exits (2 x VGA, 1 x DVI) video. Perfect!

  HTH,
