P0.0 6516-setting PCI to high causes the voltage drop across the external power supply

Hello

I use a PCI 6516 for 24V output. I have my power supply connected to pin 5 positive cable and the negative to pin 19. When I put the port 0, line 0 (P0.0) high heat, I have a voltage drop on the power supply to about 1.9V. There is no other son so there is no short circuit anywhere. The rest of the lines work very well when I put them on high. The automatic test works very well, and I tried to reset the unit several times. Could there be potential damage to this specific port? All the solutions to this problem, or anything that may have caused this behavior?

Thank you
Ahmed

  • Problems with the DC Power supply QL 355TP: I can not set the tension level

    Hello

    I'm trying to control a power supply DC via GPIB. The power supply being used is the QL355TP of society Thurlby Thandar Instruments (TTi). There are no drivers of OR to control the instruments, then I need to download and install the driver from the website of TTi: the package I installed is as follows:

    "QL - P power supplies, (including QL Series II) series pilot National instruments (Labview and CVI)"

    and I also installed the following:

    "QL - P power supplies (including QL Series II) series, IVI driver"

    So, my problem is that when I try to use the sample application of the driver 'Volts.vi DC Ouput'; defines a specific level voltage, does not work properly. The application gives no error, but it is not set the specific level voltage. However, other functions work properly, as the measure or activate the output. I tried a lot of things, but I don't know why it does not work.

    I enclose the block diagram of the application and the front panel:

    I must say that I barely control instruments using Labview and is possible that this problem would be because I did not consider things basic and mandatory.

    Any help is appreciated.

    Thank you.

    p.s. Try to replace the decimal comma to period. It is possible that the driver does not correctly handle the comma.

  • PCI-MXI-2 causes w/SP3 Windows XP Pro to freeze

    Here are the specifications of the test machine which is the gel with the PCI-MXI-2.

    Motherboard: C7P67 (supermicro)

    Mobo has no embedded video so I've tried three different cards PCIe...

    Currently installed: Geforce GT 430 DDR3

    RAM: VS2GB1333D3 total (Corsair): 8 GB RAM

    PSU: 550W

    No other devices are installed.

    We have 2 cards PCI-MXI-2 and the two freeze Windows XP Pro w/SP3 at startup.

    It gets to the desktop and then, about 30 seconds everything is frozen, unresponsive keyboard/mouse, nothing...

    Removing the PCI-MXI-2 causes the operating system to work properly.

    I installed the NIVXI331 software for the driver. We tried an another C7P67 motherboard, same problem.

    I also tried different revisions of the BIOS as well as the latest BIOS for the motherboard, the same question.

    We are trying to solve this problem with this particular motherboard (C7P67) for our client.

    I have read the manual for the PCI-MXI-2 card and the rocking U17 matches what is on the card for a 'normal' functioning (1, 2, 3 switches are "off" with the exception of switch 4 "CT")

    I also tried the two PCI expansion slots are available on the motherboard, the same question.

    Any suggestions please? Thank you!

    Thanks for your response! For some reason, the cards work now with the motherboard. Nothing has changed.

    It was strange.

  • When Firefox crashes and restart is necessary, Firefox always try to open the same tabs that caused the failure before.

    I use tabbed browsing all the time. When I open a tab of a Web site that poses a problem, freezing Firefox (but not the computer), I find that I can delete the Firefox problem only by restarting the computer. I am so appalled to find that Firefox then tries to recreate the same set of tabs that caused the problem in the first place, causing Firefox freeze again. Usually I can get it out by closing Firefox and very long wait for Firefox to close completely so that it can be restarted again.

    This problem occurs in version 4.0 as well as in the latest version of 3 that I had. I remember that in some versions previous Firefox asks if you want to recreate your tabs or open in a new browser window. I always took the second option. This choice is no longer makes its appearance.

    Set the pref browser.sessionstore.max_resumed_crashes to 0 on the about: config to get page the on: sessionrestore page immediately with the first reboot after a failure has occurred or the Task Manager was used for the closing of Firefox.

    Which allows to deselect the tabs that you do not want to reopen, but will reopen the other tabs.

    See:

    To open the topic: config page, type Subject: config in the address bar (address) and press the 'Enter' key, as you type the url of a Web site to open a Web site.

    If you see a warning then you can confirm that you want to access this page.

    You can use the filter at the top bar of the on: page config to more easily spot a pref.

  • 5V power supply seems to have failed on PCI-6221

    I recently had a test set-up down, and it seems that this could be linked to the + 5v supply.

    When I connect 5v to the unit via an external power supply Board, the Board draws 50ma, far as the 1A, according to me, the PCI-6221 power is specified as being able to provide.  When I connect the camera Board to the PCI-6221 via cable, only 0.67v are measured on the map.  However, when the cable is not connected to the card of the unit, I measure 4.5V on the power supply 5v card PCI-6221.

    I couldn't find a standard of accuracy for the power supply of 5v, but I expected to be less than 0, 5V.  It seems that my PCI-6221 power can produce a voltage in open circuit, but decreases rapidly under a load condition, which seems that the jury didn't.

    Ideas?  Thanks in advance.

    Hi Scott,.

    Terminal on the 6221 5V is rail 5V PCI bus with some type of lighter, so the accuracy will depend on the computer's power. Would you be able to try this card in a machine that has a work data acquisition card? This would exclude any power problem on this computer. If this test fails, it is likely that there is a fuse and you will need to contact us as Josh mentioned for an RMA number.

  • several PCIe - 6363 s in the same computer

    If I install 4 32 channel PCIe-6363 on the same computer (I found a Gigabyte motherboard with 5 PCIe connectors) and gains of the analog data at full sample rate (2. MECH / s on each card) on all inputs of 128 (4 x 32), I would be able to record all these data on a standard hard drive 3 gb/s, or would choke the system with this amount of flow? It could also be cooling or power with the installation of 4 PCIe_6363 issues cards on a single machine?

    Thank you!

    Stephen

    Hello Stephen,

    For PCIe-6363 devices, it is important to realize that they can taste at 2 MS/s with a single channel and multichannel rate is 1 MECH. / s, which is distributed among all the channels that you use in the task. This is because the 32 channels are multiplexed to a single analog-to-digital converter (ADC)

    This behavior is true among all our Multifunction DAQ hardware, except for simultaneous sampling (as the SMU-6368) devices, which sample of each channel to 2 MECH. / s, because they each have their own analog digital converter.

    So you would be able to acquire all 128 channels without problem, but they would be at a speed of 1 MECH. / s / 32 channels = 31.25 kech. / s per channel.

    With regard to the total disk write speed for 4 PCIe - 6363, it would be 4 devices * 1 MECH. / s per unit * 2 bytes per sample = 8 Mbps. Office of the hard drives can easily achieve this.

    You don't want to connect with a RTSI cable to make sure they all use the same clock sampling and relaxation at the same time. These devices comply with the PCIe specification, and so you will have no problem with the power supply or cooling on this motherboard. They require no external power supply unless you need additional source on their line of + 5 V, in which case you would use the motherboard connector hard drive.

    Does that answer your question? Do you really need 2 MECH. / s on each channel? Let us know if you actually need 2 MECH. / s on each channel, and we can rework the math with the SMU-6368 and discuss considerations.

    Best regards

  • HP Photosmart more B210 - printing is too high on the paper.

    The text is too high on the paper.  I can solve this problem when you generate letters and reports, etc. by simply letting a larger margin superior, but I cannot produce sheets of labels.

    I tried to change the paper size under tray settings/Main properties/device of the "letter" to "A4" - click on apply and OK - but when I check that the setting is always "letter".  Don't know if this is causing the problem, but if the book 'Letter' measures are lower than those of the A4 paper, he could be--and I wondered why I couldn't set this parameter.

    The printer is related to the Windows XP laptop and desktop Windows Vista computers.

    I hope someone can help.

    If the changes are not stick when made directly in the driver, the driver is probably corrupted. Try to uninstall and reinstall the printer driver and software package. I'll link the latest version below. Let me know what happens.

  • Accel GPU with GEForce 9800 GTX + causes the flicker annoying when using crop Overlay, apply adjustments

    From 6.0.1 whenever I go in or out crop Overlay, the area of the entire image flashes white - that is to say the image disappears to be replaced by a full white space for about 1/5 of a second.

    This happens 100% of the time and is intensely dissonant and extremely boring.

    There is also a momentary flicker a bit more subtle when you apply the settings of exhibition/hilight/shadow/white/black.  It appears the image for a few seconds (once again, about 1/5th of a second) goes back to its base state before ANY adjustments were applied and is then updated to reflect the current state of adjustment.  Happening all the time, but enough to be annoying.

    These artifacts go away if I disable the GPU acceleration . ... what I've done so far.

  • I look at the TB dashboard seen comes from open TB. On the left, I see folders. The folder "sent", lets say, is higher than the "Outbox" folder I want to

    I look at the TB dashboard seen comes from open TB. On the left, I see folders. The folder "sent", lets say, is higher than the "Outbox" folder I want to put the "Outbox" folder above the folder "sent". How do I do this ever?

    I know that the addon will allow you to rearrange accounts, so you could put 'Local folders' over another e-mail account.
    It will also allow you to use files within an account.

    So if you have a Pop email account that uses the Global setting of the "Inbox", then it should allow you to move the position of the Outbox within this special account.

    But as the 'Outbox' is a 'Local folder' folder, I'm not sure that you can move it out of "Local folders" and reposition it on another account.

    The method for moving files is done via the menu bar.
    'Tools' > 'manually sort folders ".
    Select the folder and use "move up" or "Down" buttons.
    Then click on the button "refresh folderpane' to see the new sort order.

  • A key using self-powered USB causes the base station go "off-line".

    I found that by using a USB drive self-powered, as the WD My Passport, without a USB powered, hub attached to the base of the station USB port has caused the base station go "off-line". In fact, using a powered hub does not always remedy the situation, but it is more reproducible without one.

    This is true for the AirPort Extreme and Time Capsule 802.11ac. The problem does not occur immediately, but it may happen over several days. The symptom is that the player is no longer lies in the Finder, or the base station appears in AirPort Utility.

    My question is if others have had the same results? ... and did you find permanent solutions?

    USB key "seems" less reliable on the airports of AC model than on previous versions.

    I tend to not use USB attached to routers because I think it's convenient mediocre and poor speeds. But I tested with previous models, and it seems ok...

    KT those a few posts here a me trial there. These are not self powered readers... who I have long recommended people avoid the use (without a powered hub)...

    Re: External backup drive down regularly

    In fact, the wire is different from what I remember... Age don't you know.

    But I did the test on an AC TC. The result has been very reliable. He did not cause the TC to close... but I lost the connection of the USB almost every day... except for a trial where I kept the USB drive mounted in the Finder... so that the USB drive wouldn't turn it down. He then worked for a few weeks... until what the noise of rotation of disk (sitting next to me) drove me crazy... as soon as he was mounted is more, he would pass the same existence as before.

    The previous model TC was barely big enough for the internal use of the power supply units. So powered car running disc was impossible.

    Provide EI (GEN 1-5) at 1. 8A and 12v was adequate, but the standard USB port is estimated at 500 my wrong to manage disks free power.

    You would certainly think AC 12v 5A power supply models would have a lot of power. Yet, power problems are a major problem still. Supply is extremely sensitive and stop easily for reasons I'm still to understand.

    Where the long threads on power issues to the AE.

    Now, I'm going to speculate... I think that SOME problems are associated with power.

    What is the USB port side in airports of AC? Is it still 500ma? Apple never seem to give easy to find info on these details.

    Do you know? I haven't measured it, but I can try timing the time it takes to charge a phone.  Assuming that it will immediately trigger.

    Then he will have problems with a self-powered drive. Even if the drive has less energy than quotes, current during starting is much higher. The restriction of the power on the USB port is managed by a self regulator recovery... Once you triggered it, you must stop the power... then reboot the machine to restore power.

    Then, I also did the test with hub powered... and like your results... It was better. Longer time between the drive disappears from the network. But it was not enough to stop it.

    There is another interesting effect using self-powered hubs... I discovered this on a computer running Mac OS lets say! The computer would not start with a powered hub connected to the front USB. Hubs self-powered cheap, showing a defect in their design. They can refer to the USB port. In this computer, it was enough to stumble on the good power circuit and prevent the supply, commissioning... As long as the computer is running, everything was fine... but if I turned off it would not start. I finally woke up I had to exit the USB every time. At one point, I made a "special" Cup USB cable 5v line so the hub can stay connected. You can probably just to isolate the 5v of contact in the USB. Regardless of the configuration of power USB in the AE or TC is as you can assume she's sensitive enough... and at any time when the 5V on USB hub exceeds the 5V in AE it could trigger.

    The symptom is that the player is no longer lies in the Finder, or the base station appears in AirPort Utility.

    Endangered of AU base station is not uncommon.

    It responds to the pings? I guess he still has lights but is he blocked? You still get internet through it?

    Try to open it manually in to THE... use of the file / configure from others and put the IP address of EI.

    Talk with me by e-mail... It is open in the profile.

  • Portege Z30 - A - 18 M - cannot set the native resolution on the external display

    Hello

    I tried to connect two different displays full HD to my Portege Z30 - A - 18 M and I was unable to set the native resolution - maximum resolution I can put for those is 1680 x 1050... I was not so surprised by the first that I had a few problems with a native resolution when I connect to the laptop computer Satellite I had before. But then the same thing happened when I tried the other view.

    I thought that this notebook can handle a higher resolution external... Is there a way to force the native resolution of the external display in Windows 7?
    Thank you!

    Just a question: have you plugged your Portege with HDMI cable and use only the HDMI option?
    With other words went from the desktop to the external display only computer?

    I don't have this machine, but I think you should be able to see the desktop on an external device to the HD full 1920 x 1080 resolution.

    Hi CurtisHx

    Thanks for reporting this. I agree that the error message returned by the driver is very unclear and fails to a user of the API provide enough information to determine the cause of the error in the code. In addition, it seems that we don't document the correct order of operations to set up a task well (the best thing we could find was the subject of tasks in NOR-DAQmx , who actually seems to imply that the channel configuration and their calendar can be made in any order). We are producing several bug reports, to fix / improve the following:

    • The error message returned by the driver to the API.

    • The help topic for the tasks in NOR-DAQmx.

    • The documentation of the specific method provided with the NOR-DAQmx .NET API.

    To clarify the error, it seems that 'peripheral' in ' specified operation cannot be performed when no device in the task "is in fact reference to the channels configured in the task. At this point, I'm not sure what "device" can be applied to other entities in the DAQmx driver software, but I'll post at the time where I have an error message created by the development team working on it.

  • Replace step Fail State causes the sequence fail LW/CVI custom Code generator

    Hello

    I have a Code CVI generator as part of the Toolbox ATML importer.  OR kindly gave me an example of how to change the Type of step as part of the custom Code Generator DLL and that works very well.

    However, if I try to change the step Fail value causes the sequence fail to VTRUE it seems do not set the value when the sequence is examined on a test bench.

    The code I use is:

    TS_StepChangeStepType (stepHandle, & errorInfo, typeDefinition);

    -where typeDefinition can be modified to change the type of step, it works and I can change the type of step if necessary.

    TS_StepSetStepFailCausesSequenceFail (stepHandle, & errorInfo, VTRUE);

    -who does not, the box is always set to VFALSE.

    Is there something that I am missing?

    Thank you very much

    Steve

    Steve-

    You must use the PropertyObject step to change the failure step Option. There should be a line of code the generator of custom Code that calls:

    Get the step as a PropertyObject in case it is necessary to change the properties of the General step
    tsErrChk (TS_StepAsPropertyObject (stepHandle, & errorInfo & stepObject));

    The stepObject is what you need to pass to the TS_StepSetStepFailCausesSequenceFail function as follows:

    Set the Option of failure of step-by-step

    tsErrChk (TS_StepSetStepFailCausesSequenceFail (stepObject & errorInfo, VTRUE));

    Please let us know if this happens to you to correct results.
