• How NI PCI 4474 DSA detects an overload to the input channel?

  I read "Manual user OR dynamic signal acquisition." It is written that NI PCI 4474 support only digital overload detection.

  Here's my question. What is the detection of digital overload? If an analog signal is already converted to digital signal, it can not be signals exceeds the limit. Or the DSA may already be damaged during the CDA process, if there is surcharge from the input signal. Thank you.

  Yes, the chip has more information about the Board and apply factors of calibration, which is how it can overflow.

  What we call "detection of overload analog domain" requires more equipment (i.e. a comparator circuit) to observe the input signal.  Given that the Committee in question is not a comparator to check the input signal, and the way we want to give the user an idea of whether or not their signal is too large, we simply use the mathematics inside the chip. It's better than nothing.

  Oh, and I should mention that the protection is managed by a completely different circuit.  The specification should say how much voltage you can apply to the Commission before the protection comes into play.

• Card PCI-6259 is compatible with the Dell Precision 390?

  Hi all

  I need help in answering this question.  I want to buy a better computer for my data PCI-6259 acquisition card.  I tried to search to see if the card is compatible with the PC and there's previous numbers with this set-up before other users.  Do you have a link to the list of the DAQ cards with tested PC configurations?  I want to just make sure that when I buy the computer, everything will work without problem because I only have one shot at this.

  Thanks to all in advance.

  Kind regards

  justdomechanicalengineering

  Hello

  We do not have a link to specific DAQ board/PC pairings, but the specifications for the Dell Precision 360 indicate that she has three ports PCI 5V which must be compatible with your PCI-6259.

• increase the counter timebase pcie 6259

  Hello

  Im trying to perform 2 two edge measures 2 TTL signals separation using pcie 6259. I get an error msg 200140 ' 2 active edges consecutive input signals occurred without an edge timebase counter.

  Hi the polar bear,

  Ive tried steve's idea to generate the PWM and it feeds my ctr and it works fine. If the problem was with my coupled signal with voltage comparator... you think you genius!

• What is this on my PCI DAQ connector? (PCI 6259, M-Series)

  I'm building a new rig which includes a PCI-6259, am confused by this connector:

  

  What this is, and which mates with it? This is the place where I expect the power connector PCI-E to the power of the system, or the 'hard drive connector"that the M series is supposed to have. But this has about four times as many pins I guess than to have. It is not schematized or mentioned in any job I can find online.

  Yes, version PCIe card has the supply and on the back of the card connector.  The PCI version does not work.  I think it's because PCIe is a lot of current as long as PCI, so the extra power is needed.

  Both versions have if the RTSI connector.

• My PCIe-6259 will work in a different PCI slot?

  I have a DAQ PCIe-6259 case in an old computer that experienced a motherboard failure.  I'm looking at building a new computer, but I wonder if I have to get a motherboard that has a dedicated x 1 PCIe slot, or if I can put my PCIe-6259 in a different PCI slot?  I would also welcome the recommendations of the computer/motherboard.

  Your knowledge would be greatly appreciated.

  Thank you!

  It must be a home PCI Express (PCI, not), but it doesn't have to be a PCIe x 1 location; Peripheral PCIe work in PCIe connectors longer, they don't just use the additional lanes.

• Bad drift with USB-6259 devices and acquisition of data PCI-6259

  We have both a USB-6259 and PCI-6259 installed on a single computer, linked to a SBC-68, with Matlab and Toolbox of data Acquisiution.

  For the purposes of test base, I wrote a script that generates a sinusoidal signal output based MATLAB, for a single DAC output.  I wired this single DAC output to two channels of ADC of entry.  For each sample output DAC, the script also takes a sample entry of ADC on each channel.

  --> Ideally, if everything works correctly, after you run the script, I see two channels of input ADC vector.  Tracing of each channel should give me a nice sine wave in Matlab.

  --> When I made trace data, here's what I get (see attachment).

  -->, I looked at the DAC output with an oscilloscope, and the DC offset is very close to 0 (this indicates to me that the part of output DAC works very well).

  Why is there this negative DC drift on two entries?

  Forgive my lack of knowledge - I know the difference between the DIFF and CSR connections, but I don't know where is the 'setting' for DIFF/CSR (what is a button/switch on the USB-6259 case?  Is it a software control in the code?)

• A single device showing on MAX for PCI-6259

  Hello

  I'm having a problem seeing all the channels available in a card PCI-6259. In MAX, the card is correctly classified NI PCI-6259, however in the tree view of the devices only one device is indicated 'Dev1' - where is "Dev0?

  Two devices used to be, but we gave up and I don't know why.

  I tried to reconnect the cables from the Commission on the two connector blocks has BNC-2090, or tried to reinstall the card of the Manager of Windows devices & MAX, but only 'Dev1' appears after you have reinstalled.

  Any ideas?

  Thank you

  Simone

  Peripheral will appear as a single device in "Devices and Interfaces" little matter how many connectors they have. (it's a device to the driver OR as it appears as a Windows device) The second connector simply implies that, when you run a program or a test Panel, you can now select more channels in the drop down menu to have and ao. You should be able to address all the channels of the AO in the same test Panel.

• If I use a few channels on PCI-6259 to increase the sampling rate, channels numbers can I be contiguous?

  We are looking to buy a card PCI-6259 usable on a Linux machine. We would use NIDAQmx to access the card. If we were to use only a few channels to increase the sampling rate, do I need to select specific channels?

  For example, the card is 1 MHz. If I select the channel 1 and channel 2, I can taste each channel at 500 KHz. could I choose 8 channel and channel 13 and still be able to sample each channel to 500KHz? Or need of specific channels to use when a subset of channels are selected?

  Thank you

• DAQmx Base 3.2 on Ubuntu for PCIe 6259

  I'm trying to install the package DAQmx Base 3.2 for card PCIe-6259 on Ubuntu with kernel 2.6.27 - 14-generic. I followed the suggestions of other messages to convert the *.deb packages software packages, install these and rpm install the original rpm on top packages. All this worked fine, and I can update the driver with updateNIDrivers, which prints the message as shown below. But when I try lsdaq, I get the error (as also reported by many others):

  As a note, I have NOT more than 4 GB of memory installed, and I use the mem = 4096M option at boot of the kernel.

  The logs show:

  For example, libnipalu.so does not load because of problems with nipalk. I added the niSystemReport output in this file.

  How could I continue debugging this issue? Any help would be greatly appreciated!

  (5) then the updateNIDrivers should compile fine and lsdaq works

  (6) as an aside, I could even patching this kernel with xenomai http://download.gna.org/xenomai/stable/xenomai-2.4.2.tar.bz2 , and the driver OR still works.

  A few minor corrections may be needed in this procedure to solve the problems of compiling because of the gcc - 4.3.3, but all errors may be google and trivially fixed by minimal changes in the makefiles or C-files.

• Measurement of temperature using Iex thermistor with PCI-6259

  Hi all

  I have I encounter some difficulties to measure the temperature using MAX with the installation of the thermistor Iex and would like to know if I missed something important. I use external current thermistor excited with 2 ladders and card PCI-6259 with MAX.

  This is a channel that was originally set to measure voltage and MAX approx. 900mV since this channel, OK, the voltage converted temperature is about 30 ° C. Then I added a new channel and configured to measure the temperature directly with default installation MAX Iex thermistor. This is so the problem appears: I'll get a constant-273 C instead of 30 C as expected by operating the canal in MAX. I must have done something wrong here.

  Your help is greatly appreciated!

  Bryan

  We discovered that the problem came from our wiring to thermistor does NOT of installation. If Differencial has been used, the conversion of MAX worked well. If this is not the case, only directly blood pressure will work.  Bryan

• Effects inactive clip on output

  Problems can usually be broken down into the following categories:

  (1) system
  Windows 7 64-bit family

  2.) assets (Audio, video and images)

  12 + minute of the project containing images, audio, video and photo.

  3.) project (how it is configured and Preset)

  Unknown presets. I guess it's Setup is normal...?
  4.) workflow (what you do and how you do it)

  Put the titles on Audio 1, add in still images and some videos in video 1, 2... According to the needs. A lot of drag / move, quick keys, mainly using the timeline. Transitions, disc menus, effects, etc...

  Question:
  The photo frames still have effects applied to them (earthquake, old movie) and although the effect works on reading PRE/Elmts/8, it applies only during transitions of these frameworks to the next section on the output (AVI and MPEG).

  
  Pleeeeaaase help me.
  Thank you in advance.

  I use 8 items Pre and I had asked for the effects to still images, in this case. And to answer your question, I used other effects and all seem to work fine.

  After reading your comments, I had an idea that worked really out. I simply put a movement timed for the duration of the fixed image!
  My output is AVI in order to transfer it to my laptop and create the DVD it as before on my PC randomly finds and loses its detection of my DVDR...

  I will update again in a few moments, because I have not tested with the earthquake effect yet but I am sure that it will work.

  Thanks to hunt.
