• USB ports still under voltage after power off

  Hi, I use a sleekbook of 6-1260ez want on Win8 x 86. After I power the system off, the USB ports have always power. The wired mouse LED is still. In addition, the laptop batteries are drained after 2 or 3 days without being plugged in, although the power is off.

  I installed the latest chipset drivers. the option "Scan now" on your support page is not find old drivers. What can I do? Is this a warranty case?

  P.S. This thread has been moved from the Notebook - HP ProBook ZBook, EliteBook, Compaq, slate/Tablet PC, Armada, LTE for laptops - pavilions, Presario. -Hp moderator of the Forum

  This computer has a usb 2.0 support. That so you can recharge your cell phone or your mp3 player with the computer turned off. I found and read the manual of the computer.  That is why your mouse is always on.  Then you'll have to unplug the mouse when you're not using it. I hope help you.

• NEITHER USB-6343: erratic low frequency 1 counter measures

  Dear members,

  I'm looking for help with a measure of low frequency counter.  I tried to make it work for a week or two, but I keep getting erratic measures.  It will read the rpm properly for a second or two and then it will give a ridiculous value on the order of 10,000 times the correct value. I can not get a constant value.

  I use a DAQ series X NI USB-6343 multifunction with Geartooth Honeywell GTN1A111 sensor. I enclose a sketch of the wiring configuration.  I think that it is correct.  Sensor output to the door of the meter.

  To try to solve this problem, I hooked the sensor to an analog input channel to make sure that I was getting a TTL signal by sensor.  I noticed every once in a while I'd see a glitch of little noise in the signal and I guess that's what is causing my problem with the meter.  I inserted two waveforms of the sensor signal (one with the clean signal) and the other with the glitch of noise.  My understanding of a TTL signal meter channel will examine LO voltage when it is below 0.8V and HI when it is larger than 3.8V.  So I really do not understand why these little glitches could be the cause of the problem because they are well below and above 0.8V and 3.8V, respectively.  I think that the noise comes from a frequency converter used to drive the engine.  I tried the system as much as possible of the Earth.

  

  

  I guess I'm looking for another approach.  I could potentially use a digital filter to help with noise? The glitch is in fact the problem or I forgot something.  The VI in question is attached.

  Thanks in advance,

  Mike

  Have you tried to set up a digital filter yet?  Obviously the seeds are collected as an additional transition (the method of low frequency counter 1 measure the period and then reverse, so a short glitch would record as a very high frequency).

  You can enable the digital filter with the following property node:

  

  Min pulse width is guaranteed pulse past the filter, so it should be low enough for the real signal is guaranteed to pass through (but high enough so that the glitch is always rejected).

  Best regards

• NEITHER USB-6343 analog and digital grounds

  In the manual for the NI USB-6343, it is said that the mass input/output, analog and digital terrestrial are related, but by a small sign. For my application, I am attaching all 3 these grounds to exit the box (I'm tie all areas with physical threads). It is perhaps a silly question, but it's OK to do, correct?

  This should be OK unless there are large currents flowing on ground conductors.  If you have important currents in the ground, you have other problems that must be resolved before you connect the DAQ hardware.

• USB ports suddenly freeze and stops working for 10 sec after power off or powered speakers

  Original title: Usb Ports stop working for 10secs after power off or powered speakers!

  Hello

  I have no why, but my usb ports suddenly hangs for 10secs when my speakers turned on or off the power in case of operation of pc... And I have a usb mouse usb wireless keyboard and... with this problem that I can not work properly... and some times my mouse work in early upward and then I should use my keyboard to restart the pc... Then it works very well! Help me please. !

  Hi Thierry,.

  This issue does not appear with Windows that even after you perform a clean installation. So for me, it looks like a material damage. I would recommenmd get you in touch with the manufacturer of your computer and to do the repair.

  Do not hesitate to contact if you have problems with Windows in the future.

• Simple examples of analog output USB-6343

  I've tried passing by 'find' examples and does not know how to find what I want.

  I'm doing a simple analog output on a USB-6343.  Examples of waveforms say they work with the USB-6343, but I really don't want a waveform, just analog of output does not exceed 10 Hz speed of renewal.  Some of the more simple examples show that they work with the pcie-6343 but do not list USB-6343.

  I worked with USB-6009 in the past, but when I try to use an analog output task that uses 1 sample on request, I get the error "not buffered operations clocked by the hardware are not supported for device and channel type.»  Set the size of greater than 0 buffer, do not set up the timing of the sample clock or the value Type of sample On Demand time"

  I tried samples N, 100 samples to write to 10 Hz - the same error.  Samples of continuous - same error.  1-sample - timed HW - same error.

  There is a series of examples of I/O for the X series?  Is it possible to search the device examples rather than go through all the examples and by checking the list of devices individually?

  Is 'size of the buffer' the 'writing samples"in MAX?

  After contacting the support I was provided with the names of the more simple examples for analog i/o:

  Analog output-Gen power Update.vi

  Analog Input-Acq & chart voltage-Int Clk.vi

  They are found in the getting started screen of

  Click 'Find examples' near the lower right corner

  Filter the results to material by clicking on the menu drop down for the material in the lower left corner and selecting USB-6343 (only connected equipment will be displayed)

  Don't forget to check the box "limit results to material" below.

  In the center pane, double-click 'Material Input and Output'

  Double-click DAQmx

  Path for the analog input - double-click Acq & chart analog measures - double click on tension - tension-Int Clk.vi

  Double click on analog generation - double click on Power - Gen Update.vi of analog channel output voltage

  The examples are for the single data point.  Samples and exit multiples are produced by putting the writing or reading VI inside a loop.  The beginning and the clear functions should be out of the loop.

  Additional information, I need technical support was how material-filter results and identification of more simple examples which were not obvious from the examples of names.

• NEITHER USB-6501

  Hello

  Could someone give me some information about whether it is possible to use the

  NEITHER USB-6501

  As a generator PWM to control the dimming of 18 power LED function?

  calendar is not so relevant and if the pulse width can be controlled in the PC itself application the purpose would be financed

  Hello ONavarro,

  It is technically possible, but please note that USB-6501 as only software clocked e/s digital (e/s static). In other words the duty cycle of the PWM periodocity Ant you want to generate will be determined by a loop software, so depending on your system and the USB bus. I think that you will not be able to get a better rate of loop (ability to change the State of a digital line) less than some milliseconds (depending on the system).

  By example, if the loop runs at 5ms, and I want 10 steps in my PWM, this means the period will be 50ms, therefore a 20 Hz base frequency. If you can't reach 1ms, you will get 100 Hz. If you want more than 10 duty cycle value, you reduce the frequency.

  And it is NOT stable (loop software 5ms, first delta 5.8ms, then 4.9ms, 5.1ms, 6.7ms, and so on), because it is based on the software. If you need something stable and faster, choose a device with hardware synchronizing.

  Best regards

• Measurement of temperature using NI USB-6343

  Hi all

  Someone at - he temperature ever measured using an NI USB-6343 or something close to it? Encountered problems?

  I was reading on the device and it has been suggested that the conditioning of signals may not be required, and I'm a little worried...

  Normally I use a DAQ Agilent but this specific project, I'm working on that will require a unique moment and USB-6343 handles a majority of my problems along will be many examples of coding.

  -scrider

  Scrider,

  You want a device that has USB connectivity like the 6343? If so, we have several hardware based USB DAQ for thermocouples. The links below will show 3 devices, we have:

  http://sine.NI.com/NIPs/CDs/view/p/lang/en/NID/208177

  http://sine.NI.com/NIPs/CDs/view/p/lang/en/NID/201881

  http://sine.NI.com/NIPs/CDs/view/p/lang/en/NID/207471

  Now, I know that some of them will probably not ideal for your app, but I wanted to just give you options. It also depends on how fast you want your sample rate is. These devices are specific for the use of thermocouple, but you can still use them (excluding the tc01s) for voltage readings. I hope this helps!

• NEITHER USB-6008 connect to thermocuples and pressure sensors, control valve

  I am endevoring to build a gasification plant biomass for bench scale test process control plans. NEITHER USB-6008/6009 will be adapted for use as a data acquisition. I'll take RTDS, thermocouples and pressure sensors. I don't want to use industrial automation controllers.  It is also possible to use the channel of analog output for sending signals to a control valve position (using sufficient current/voltage between the two drivers).

  (1) OK.  I just wanted to be sure that you were aware of the potential dangers.

  (2) an RTD is a resistance that has small changes in resistance per degree of temperature change. To measure that you have need of a current source and a sufficient resolution in order to detect small changes.  At 25 degrees C a typical RTD is 109,73 ohms and resistance ohms 0.38 per degree changes.  If you had 1 my crossing this RTD voltage through it would be 109,7 mV and the voltage change of 0.38 mV by degree.

  The resolution of the 6008 on the most sensitive range is 0.49 mV > 1 degree.  The accuracy of the 6008 is 1.5 mV typical.

  For a Type K thermocouple, voltage at 25 degrees is 1.407 mV and change by degree is 39 µV.  Millivolt solving half of the 6008 translates into about 12 degrees.

  If you need a source of excitement for RTD and a kind of amplification for thermocouples and RTD before she would make any sense to try to use USB-6008.

  (3) I have not used anything except LabVIEW with DAQ devices and drivers.  I think DAQmx can be used with MATLAB and other languages.

  (4) the 6008 is the low range made by NOR. You will need to go to a more expensive camera or add signals conditioning circuits.  Talk to your representative OR assistance in the choice of a suitable device.

• Frequency counter measurement crashes when you're away point zero (NI USB 6343, error-200284)

  Members of the Forum,

  I have problems with a measure of the frequency on a DAQ Mulitfunction of NI USB 6343 X series.  I use the meter 1 (door axis for frequency signal, PIN to DGND 82 77). The couple HBM T10F flange that I use (powered by a power supply of 24V) emits a signal of frequency between 5000 and 15000Hz with 10000Hz being the zero point. Couple flange has a capacity of 5kN.m (15000Hz = 5kN.m; 5000Hz = - 5kN.m).

  I have been using the VI attached for a few months now without any problems.  Now, the VI works fine as long as the couple remains inside a few hundred Hz of the zero point.  However, when the frequency increases further reading couple begins to freeze and finally I get either of these two errors:-200279 or-200284 related samples is not not available.  I noticed that the light on data acquisition close compromise during these periods of frost.

  Here is an example step by step my problem using cal shunt of the flange of the couple:

  1. I have run the VI and couple bed properly around 10000HZ (Active light, indicator light ON)

  2. I have apply the excitation of 5V to the shunt cal and frequency climbs to about 50% of the ability to couple brackets (as it should)

  3. as soon as I remove the excitement 5V playback freezes and the light on the acquisition of data.

  4 if I apply the 5V once again, until the timeput occurs, the led turns on and the acquisition of data reads the signal correctly.

  This type of problem would be more DAQ-related or is it the flange of the couple itself.

  Thanks in advance,

  Mike

  Solved.

  I did some troubleshooting this morning and it turns out that the vibrations of the system had not tightened a screw that was connector to the stator flange torque causing a bad electric signal of the torque flange itself.

  Everything works fine again.

• EliteDesk 800 G1 USDT: usb ports do not provide enough power

  We have a scanner usb requiring 500mA of power.  However, for many of our clients using HPs, the usb ports do not provide enough power to the scanner causing the application to crash.  Some customers use the HP EliteDesk 800 G1 USDT, others use HP zero client t310.  Connect the scanner to a usb hub powered solves the problem every time.

  Y at - it changes, they can do for the Bus USB controllers to ensure that a particular port will be able to provide 500mA so they did not need to buy a usb powered a system hub?  Or do you have another suggestion?

  Thanks in advance.

  I'm not familiar witht eh models accurate but 500MA is the output for USB 2.0 max but 3.0 can go higher have you tried usingn 3.0 ports if not you can also get a cable Hat uses the power of 2 ports.  Many systems have problems with the only Scanners USB and power supply.

• Airport Extreme (ME918LL/A) must be Factory Reset after power cycling

  whenever I power cycle the router (at the suggestion of Cox), I end up having to reset completely by holding the small button in the back (for factory reset).
