order a fan with USB6251 and the Daq signal accessory

Hello

I have a school using Labview project and the USB6251 connected to the Daq signal accessory card.

The Labview program must read continuous temperature (Ia 4 channel, internally) temperature probe connected to the accessory of Daq Board signals. When the temperature reaches an established value, then a led on the front panel should be lit and a singal output data acquisition should start a fan connected to the acquisition of data which cools down the sensor, then stops.

Would it not be possible to do something like that? Even if I generate a square signal and the fan only works on the State of the signal. The fan requires at least 120 mV DC current. I'm afraid that if I take these courses for the acquisition of data, I could damage the unit.

Thank you.

I guess you mean 120 current my DC . If you look at your spec of daq card, you will find that the current max are far below 120 my. This applies to the two analog out and digital out. Take a look at this site, it may be useful to some. site nice http://www.me.umn.edu/courses/me2011/robot/TechNotes/motorcontrol/motorcontrol.html . If you want the speed controller, you have two options PWM or voltage of the motor regulation.

Good luck

  • Want to Phoenix 860-010: problem with fonts and the noisy fan

    I have a new machine, just a day old, and I'm having a problem with fonts.  The file Explorer, Edge and other similar programs seem to go from a very readable font that lights up in half a second or less whenever I move down on the page in these applications.  Police that results is much more difficult for me to read because of the lightness that results. I have not met this problem before.  Frankly, I don't know the source of the problem.  Is it hardware (video card) or (Windows 10) operating system software?

  • HP Envy 15 "touch screen power LED appears, but the fans does not and the screen does not light

    Hello!

    I'm a student in computer engineering at the University of Waterloo 1A, and I run a very serious problem with my HP Envy 15 "TouchSmart laptop computer running Windows 8.1. It is a problem that just started today, and I'd rather have a first support here before going to see the technical support Office sometimes tomorrow. It has to do with the screen and the fans where the Power LED lights in white, just as when the laptop works properly.

    (I have warranty on the laptop when it was purchased last June, except that if I find that I need to get a replacement, I'll lose all my work, I did on that since I started my semester.) It's so silly of me not to have all my work saved on a backup, because I have an external hard drive. Problem is, I've had too many problems in getting myself organized, I'm not being open-minded as I should, and worse, I'm not a balance between life and work at home.)

    Before I had my MATH 117 conference (Calculus 1 Engineering), I was in a nearby lab where my laptop was open and turned, works correctly. I've had NetBeans IDE running since I wanted to work on the second part of my current assignment of CS 137 (principles of programming). Because it was almost time for my presentation, I closed the laptop by simply moving the screen down on the keyboard, where it goes into mode 'sleep'. (Whenever I flip to the top of the screen, the laptop is supposed to return, and the sliding screen of Windows 8.1 connection will appear.)

    When I took my seat for reading, I wanted to spend a little time to work on my programming assignment. However, after the reversal of the screen to the top, instead of having the login screen appears, I encountered the problem: the power supply light is showing a white light, but I don't hear the fans between the ventilation openings on the left side of the laptop and the screen does not light. I tried to take the power for several seconds and once button at least 10 seconds, except that the power light continues to display on a white light. The Commission of the Wi - Fi light is not displayed.

    Whatever it is, I don't want to take out the battery because I have that on my last laptop, and it's from there that I couldn't turn to the former, a new market. If I leave the Envy laptop battery, it will short-circuit the connections between the battery and the computer, and so several components will FRY. For now, what I do let the laptop is to empty the load on the battery. Then, once I noticed that the power light does not project a white light, or plug in the AC adapter and try turning the laptop on the power button.

    It will take a little while for the circuit drain the load on my battery but...

    Anyway, please would you be kind enough to help me with this problem? I would really appreciate if you can give me several recommendations. Thank you!

    Concerning

  • Problem with LED and the comparison.

    Hi everyone, I have trouble with this application, so I hope that someone could give me some advice. Im going to explain as best I can...

    So in this VI, I have 4 signals that I need to compare them, I need the smallest and largest value, so I used a restructuring of business to do. I do 2 groups to be compared, and then the result of each one of them receives another comparison to get the values that I want. My problem is, for the largest value of all the 4, I need an LED to indicate what is most great, and something I have is in my attachment. I take my first group two and put 2 LEDs, so when the comparison occurs, you turn and the other goes OUT, (which indicates that one is the largest and the other is the smallest), and again the same thing in the other. But as you can see, when running I have two LEDs indicating, in every comparison, which is great, but I need a LED lights up when this value is present. and the other three offshore. I know that work in this way, the result I m going to get, but I can understand how to continue with the result of this step, I need.

    As far as I know, there is no way to compare more than 2 signals at the same time, so I tried to merge the signals, but this didn t help me at all (maybe is something that I do not understand how to merge works, so if anyone has an example on how to do things, i´ll check).

    All data are dynamic, a NI 9237, but since its a laboratory, I can't get a lot of time trying different solutions, so I did a test TDMS file and change the DAQ Assistant for a reading of file of the measure, but the rest is the same.

    Use 'antenna bundle' to build a picture of your values of 4 controls. Return the index of the max and min elements, use 'table max and min. From there on, it should be a wink to indicate the corresponding settings.

  • Computer is humming, fan turns on and the screen is blank when I start computer

    This problem happens every 90 days. When I took the computer to the repair shop, he had no problem with him right there.  If the computer remains stationary, the problem persists, but once it is moved in a certain way, it will start normally. Specifically, I spilled on the computer and the problem stopped.  I have a hard time to explain a problem to the repair shop when it no longer exists at the time wherever I have it get there. Is there a more permanent solution that mess up the computer?

    When I tried to turn on my computer, I get a buzzing sound, then the fan came and the screen remained blank.  I tried to restart after an hour, but it's the same, what's the problem? >

    Hello DempseyBullock,

    Sorry, you experience this problem.  The first thing I would say is contact the manufacturer of your computer.  Also, I suggest to go to the manufacturer's Web site to confirm that there is no news updates for the drivers, firmware, or BIOS updates.

    If you are unable to start your Windows XP-based computer, try the steps in the below links:

  • HP ENVY 700-000z Desktop PC with 8 and the need to know if I can install Windows 7

    Just bought HP ENVY 700-000z Desktop PC equipped with 8 and need to know if I can install Windows 7 on this computer without problem.  My work does not allow the use of Windows 8.  If I can install Windows 7, what version of operating system do I need to buy to do a clean install.

    If I understand correctly, I could order the Windows 8 Pro, who has right to demotion and then install Windows

    7 pro, I have then I should be able to get the drivers, I need HP is correct.

    WARNING *.

    HP does not recommend installing Windows 7 on a computer comes with Windows 8, and it will support the installation of Windows 7. HP doesn't provide drivers for Windows 7 and the appropriate drivers are not available for the hardware in the computer. In addition, Windows 7 can not take in charge some of the hardware or software designed for the computer.

    Make sure you create your media recovery HP or USB Flash Recovery discs before you edit or change anything.

    You should ENABLE 'Secure Boot' and maybe 'Legacy Support' in the 'BIOS Setup boot secured' on the settings page below, before you try to install Windows 7;

    or

    In addition, as the hard drive is partitioned as TPG, you must start the computer by using the "UEFI - CD/DVD drive" in the start menu "F9". If "UEFI - CD/DVD drive" or something to that effect does not exist in the start menu, please post a screenshot and/or make startup listed options.

    I suggest using Windows 7 SP1 for the best installation experience. If you need Windows SP1, see 'How to install Windows 7 without the disc' to download and create your own. If the DVD does not start as UEFI, you may need to use a USB Flash drive (can ask "Quick start" DISABLING in BIOS) as the installation media. Please download the Windows 7 USB/DVD download tool to create a Windows 7 SP1 USB Flash drive.

    Most of the Windows 7 drivers from the drivers of HP Pavilion p7-1299 c desktop PC page should work on your desktop HP ENVY 700 - 000z CTO. Both models use a variant of the motherboard HP Jasmine. If you have missing or unknown devices after installing the drivers, please post the "Hardware ID" Device Manager for devices as shown in the example below.

    If you have any other questions, feel free to ask.

  • Problems with fonts and the Fontcache.

    Recently, I noticed that a Svchost was running constantly at high CPU usage, as well as a few programs had stopped working on my PC. After doing some poking around, I believe the problem to be with Fontcache and my fonts. It turns out that my partner has installed a large number of fonts, which I suspect to be corrupted. Unfortunately, I can't open the fonts folder, or the section fonts in Control Panel.

    In an attempt to put an end to the use of the processor (which I think is of Fontcache constantly trying to start upward - and otherwise), I have disabled loading in services, however it still loads up when I try to start a program like InDesign. InDesign will also not load, I suspect that for the same reason.
    I could not remove all the fonts, or find no way to remove them, without access to the section fonts in Control Panel. I tried to access via a command prompt and just can't take the ownershop/control of them to remove them. All of the guides I found on the internet forced me to open the folder of fonts/Control Panel and manually change the permissions using the Windows user interface, but obviously I can't do that.
    Does anyone have a solution to remove fonts or an another workaround for the problem?
    Thank you

  • My computer will not sleep, the display shuts off for a while but the fan still works and the keyboard lights stay on, and then eventually he dies just

    Imen quite so much as the title, when I try to put my computer to sleep the screen turns off but the computer is still running. My computer is a HP pavilion dv6 is a little more than 3 years. He used to do whenever a while, but now it's every time I try to pause. I'll close the top cover, but the fan still works, the hp on the lid logo light remains lit, and if I reopen it cover the power light is always on and the lights on the keyboard caps lock and wireless keys. The same actions occur when I try to put it to sleep manually (from the start menu). It does not at all I have to do another that now hold power, but even when I do nothing, it will stay here like this for awhile and then just turn off completely.

    When it starts up, it gives me the options to start in safe mode or start normally, and when I am connected and it gives me the "windows has recovered from an unexpected shutdown", I see that there is a minidump file in windows that has something to do with it. I tried to search for the file and the problem together, and then each separately, but nothing I've seen described really my problem, so I thought I should just ask on my problem.

    I read what made other people, changing advanced power settings, changing the media settings, etc. and did those things, but to no avail. It's not a huge deal, because I can just turn off my computer whenever I'm done with it for now, but I don't know if it's a bad omen for the future of my poor computer. So if someone could give me a hand with this point in mind, I'd be very happy. Let me know if provide more details (OS, processor, my favorite color, social security number, etc.) that would make it easier to solve. Thank you
    Also, either by the way, if this is in the wrong forum topic, please let me know.

    If you use a wireless keyboard or mouse to your computer, these items can keep your computer enter standby mode automatically because they constantly send a signal to the system, thus preventing downtime. An optical mouse (that changes color) causing a similar problem.

    Hmm, it seems that it could be anything really.  Did you follow protocols of discharge of static electricity when you deleted the C2D?  If so did you remove the radiator and the fan of the C2D for a reason, then put back on the C2D when you re-installed?  It could be that the thermal paste is not contact correctly and the system is overheating.  If none of this applies, I unplug the unit, unplug the processor fan and remove the processor, making sure that none of the pins are bent and is clear and try to put everything back in and locking down.  It could be something as simple as a card not in place or something.  Are there patterns of diagnosis on the xps210? Or no beep codes?

  • HP OMEN: Windows 10 fan HP Omen and the keyboard does not

    Hello, I own a HP 15-5013dx Omen and I reserved a copy of the update of Windows 10. Since I installed the update, my HP OMEN control program could change aspects of my machine.

    I used to be able to edit the variable my fan speed and the back lighting for my keyboard on Windows 8.1, now I can't do that.

    It is a great concern that fans help to keep my calm of laptop for watching movies, surfing the net and playing games. Where I write this, I have a zero of my fan operation. No cooling that does so ever.

    FN + f does not respond, I practically lost control physically and virtually. Does anyone else have this problem?

    p.s. I deleted my Windows.old folder by accident, so I can't downgrade to Windows 8.1

    Just make sure you change the model to YOUR specific model. It should be the same for all the omens, but just to be safe, go to yours in the link.
