• 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

• Why is there not coherent diode to 0,7 v voltage drop?

  Evaluation version of Multisim11 students. In a domain controller series simple circuit with a resistance of 10 ohms and (3) in4148 diodes before biased, voltmeters through each equal tension to the diode with each diode, but when the dc supply voltage increases, the voltage at the terminals of each diode increases. A technician quiz (and the theory of diode) indicates that the tension will change not through the diodes and should stay at 0.7 to 1 diode, 1.4V 2, 2.1V through all three together, even while the supply voltage is increased, but why not Multisim reflects the basic diode theory? I use the default settings for counters and components. This was also a problem for reverse and measured from current levels of polarization tests. I'm almost never able to get the same results, as provided for in the school laboratories.

  10vdc, I get 1.593V each diode

  Get 3.777V each diode to 30vdc

  What's the dealio?

  I can I answered my own question by experimenting with the circuit. The value of 10 ohms resistance is not high enough to avoid overloading the diodes. A value more realistic of 1Kohm and tensions of 5-10 v using 3 diodes BAS16 show diode drop of tensions in the range of .691mV to .750mV. 30V even still shows a drop of .836mV diode.

  So what kind of diodes would work correctly in this circuit with a resistance of 10 ohms in series and a range of 10 - 30V dc voltage? The quiz of technician stated that this circuit has a resistance of 10 ohms. Maybe it was a typo?

• Why has the drop-down list of search engines under a simple list to a field of identical icons?

  Until the most recent update from the drop-down list of the available sites in the search box was easy to read and simple to use. Being able to target its research so easily and conveniently was one of the attractive features of Firefox.

  Now, I am faced with a range of more often indecipherable and in many icons that can lead to confusion of case. I hate it and I want my simple ad verbal back!

  Yes, mousing over the icons and hovering will reveal what they represent. But to have to do this each time which was a quick routine and practice irritating slow and clumsy.

  Please give us at least choose to have icons or a list. Please...

• Why large images will not open in full screen on first click?

  I'll open an image (jpg, png) that has a size in bytes of 2000 x 3096. What ends up happening, is that it is initially open a window full screen, and after a second or two, this window full screen will be reduced to a window screen. Now, I have to click on the maximum window size button in the upper right to expand the window to full size, click with the right button on the image, select Image seen on the menu drop down and then finally click on the image so that it can display in its original size.

  Y at - it a plug-in or a config. setting I can use, so that the image opens in the mode full screen from the beginning?

  Is it with a link to the opening image of a web page or to view pictures that you have already stored on the computer?

• Why the first drop function in Adobe Reader DC move then all the downs only works if the application is restarted? [iOS]

  Any help on this would be greatly appreciated.  I have a file with several drop downs.  Whatever one you choose first works, then when you try to select other or re - edit selection down down cannot unless you close the application completely and restart.  Then it it works again.  Very annoying!

• Why the Adobe drop would be even with CC?

  It is not acceptable that Premiere Pro CS6 download is the only way for the CC to author DVD customers. Besides mauled Adobe that greatly with so little communication on this subject.  I myself am bounced three representatives of different media before that someone had told you to download again with Premiere Pro CS6.  The DVD market and the demand is much too large to be cut at this time.

• Why does the drop with a Spry Widget 2.0 last two taps to turn on iPad?

  I have the 2.0 Menu pretty well composed Spry in the way I want it.  When the user clicks on the menu item from an iPad or iPhone also, however, press the drop-down menu twice to make it work.  All the menu items work very well on the first tap except those that have a menu drop-down.  Is there a way to get the drop of pop and work on the first valve of an iPad?  Here is the code of this aid.

  Well, I was able to find a work around for a post in the forum a similar problem.  Here's what they have posted and it worked for me.  I just hope this does not break anything else.

  Change the lines above the lines on the bottom.

  I was able to actually understand the other night.  I needed to change that:

  var MenuBar = new Spry.Widget.MenuBar2 ("#MenuBar", {}
  widgetID: "Menu bar",
  widgetClass: 'MenuBarRightShrink the menu bar. "
  insertMenuBarBreak: false,
  mainMenuShowDelay: 100,.
  mainMenuHideDelay: 200,.
  subMenuShowDelay: 100,.
  subMenuHideDelay: 200
  });

  TO:

  var MenuBar = new Spry.Widget.MenuBar2 ("#MenuBar", {}
  widgetClass: 'menu bar MenuBarRightShrink '.
  });

  I hope that doesn't ' t mess up anything else, but no problems so far.

  I checked with the two tech video card and game and they are puzzled at this.  I spent over an hour on the phone with a technician of blizzard and tried all sorts of things to the point, we ran the game to the bare minimum, and again, I got the same problem. I was also in live chat with nvidia technology and that he did not see the problem.  the only programs I have installed are windows 7, ventrilo (who was not working at the time) and world of warcraft.  I was running vista before and had no problem.  the only difference is win 7 home.  I've read several different forum and the only people who do not have a problem like mine are running ultimate.  What is the difference which would cause these spikes?  If I don't get all the answers that can help I hate to say I'm going back to my old OS and must say to others that win7 is a waste of money.  I spent too much time trying to find a better system that has been a big disappointment

  If you were also frustrated that I was u would say worse but it was not even win 7 which was my problem, I have to say.  It ended up being my new processor was too hot. thermal protection has not been applied to work at the new thermal grease, and now it's great.

• Can a module SCXI 1102 with a block of 1303 b cause some channels of reading of the voltage signals and other signals of current reading at the same time?

  Hello

  I'm trying to use two sensors of moisture Omega HX85BA and experience two CFI mass flowmeters in current loop. Humidity sensors have three outputs 0 - 10V, while flow meters have two outputs 4-20 Ma. Can I have all four sensors to wire to the same block of connection SCXI-1303 and read all the signals in the same VI? the block is connected to an SCXI 1102 b card and a 6052E DAQ of NI PCI card.

  Thanks in advance!

  Hello BBalmforth,

  Yes it can. Although you will need external resistances (I recommend resistors precision for better accuracy) for current signals. The SCXI 1102 b is indirectly measuring the current by measuring the voltage drop across the resistance. The table below describes the current diagram and how it will seek in LabVIEW and DAQ assistant.

• several daqmx read iterations do not run correctly

  Hi all

  I have trouble getting my new VI to run the way I want it. The goal of the sub - VI is to measure the voltage drop across a component when a pulse is provided for a time defined by the user and then wait for a time defined by the user. It fulfills this task exactly how I want it however, I need to set up a series of pulses with differently timed pulse lengths, queue time, voltages, etc.. So now, I have a just basic model run this twice. When he starts the second iteration, he made a strange leap like maybe the second pulse is to crush some end values of the first impulse. Even more strangely, from the second pulse, it seems to re - run the first impulse. These behaviors are quite clearly stated in the charts. I guess that the problem is in my pulse sup - VI, but I'm not having much luck trying to debug this. I use a NI 9264 for pulse generation and a NI 9205 of data acquisition. Thanks in advance for the help.

  Bradley

  Where's the second iteration? It's not not obvious from the code you set. Do you mean the second image of the sequence of flat? Why not place things in a loop? Now simply once the failure of the Subvi.

  First of all, your Subvi is extremely inefficient. To create the data of the pulse, you must use a loop FOR and autoindexing in the tunnel of output rather than build the table element by element using insert in the table. You can even use the "model pulse" instead.

  I don't know what is the goal of the iteration OF the loop. Currently it is just a glorified sequence frame.

  All your configurations data acquisition must be exactly done once at the beginning of the program, and not every time from scratch inside the Subvi. Also, it would seem more appropriate to use the same clock to HAVE and AO. There is currently no guarantee that they are in sync.

• virtual lamp

  I'm an apprentice electrician first year and that you have installed recently Multisim v11.  I can't find information in the help files to answer these questions and hope for more help.  Why a filament is sometimes Red?  Why the lights sometimes flash?

  Thank you

  Greg

  Greg,

  Multimeters of wire in each of the 3 lights.  You will see that each lamp has a different voltage through it.  If you compare the voltage across the lamp with the with the nominal value of the lamp, it follows that what I mentioned earlier.  Voltage too low, the lamp is off. Tension near the coast, the lamp is on, but not red.  Voltage equal or superior, the lamp is on and red.

  The voltage drop across each lamp is based on the setting of the voltage and the power of the lamp.  Multisim seems to use of a simple Ohm's law calculation to determine the resistance of each lamp based on the voltage and power.  The formula is R (ohms) = (v * v) / Watts.  If you are replacing each bulb with the calculated resistance, the voltage drop will be the same.

  See the attached file for the link between the tensions as well as the effect of the tension along a sine wave AC on the flickering effect.
