• USB-6289 digital output signals setting

  I use a USB-6289. I am writing a CVI application that uses this device. I need to put the digital i/o pins as outputs. In the CVI app, I know I can create these tasks with the tools-> create/edit DAQmx tasks. He created this:

  Int32 CreateDAQTaskInProject(TaskHandle *taskOut1)
  {
  Int32 DAQmxError = DAQmxSuccess;
  TaskHandle taskOut;

  DAQmxErrChk (DAQmxCreateTask ("DAQTaskInProject", & taskOut));

  DAQmxErrChk (DAQmxCreateDOChan (taskOut, "USB-6289/port0", "))
  "DigitalOut", DAQmx_Val_ChanForAllLines));
  DAQmxErrChk (DAQmxSetChanAttribute (taskOut, "DigitalOut", DAQmx_DO_InvertLines, 0));

  * taskOut1 = taskOut;

  Error:
  Return DAQmxError;
  }

  So this it puts in place but not to write the data. My question is what is the command to write the data?

  Also I was wondering if the code source of any example that shows how these commands are made? Is it possible to configure the bits individually? I only need to use 5 of these pins as outputs so t would be coll if I could write that the bits D0 - D4.

  Are there documents written on these commands and how they are used?

  Thanks in advance

  A DAQmxWrite writes the data.

  Go to help > examples > material input and output > DAQmx > digital generation.

  If you specify the lines instead of a port, you can use as the number of bits you want.

  First glance using the ICB.

• HP 50 g - PC connection series with adapter Series USB and null modem troubleshooting

  I have the calculator correctly connected to my laptop via a USB series adapter, which is plugged into a null-modem adapter, which is plugged into the serial cable sold on HP Calc.org specifically for the HP 50 g. I started XModem on the calculator, but Conn4x found nothing. Is the process different from that used for USB and Conn4x connections? The problem could be with the USB Serial Driver. I use the default MicroSoft driver installed to connect? Are there tests I can run to determine if the adapter is broken, or the computer or calculator. Thank you very much in advance for your help!

  I already tried the following:

  • The two indicators relevant system are correct for the serial communication
  • Tried to reinstall the driver
  • Google for any relevant information that is extremely rare
  • Tried with two Xmodem Kermit servers running on the calculator, press 'Connect' on Conn4X.

  Hi!, Ranothil:

  If you have the following cable "null modem" (http://commerce.hpcalc.org/serialcable.php), you can transfer, all

  data, HP50G, to the PC and vice versa, throughout the connection Kit (Conn4x), without issue.

  Please, see this link, to education, to transfer data with the serial null modem and connectivity kit cable... http://sense.NET/~Egan/SKB/ or... http://www.hpmuseum.org/cgi-sys/CGIwrap/hpmuseum/archv017.cgi?read=125259

  Note: best if you transfer data, HP50G, PC and vice versa, through the microUSB.

• synchronize two usb 6289 with a meter

  Hi people!

  I'm trying to synchronize 2 boards of the series M USB-6289 using a counter.

  I searched the forum and that you've already seen the tutorials:

  'Synchronization of series M with LabVIEW and NOR-DAQmx - Developer Zone - National Instruments'

  'Synchronization of data acquisition USB - device to several systems - Developer Zone - National Instruments'

  "The time and the synchronization of the NOR-DAQmx - Developer Zone - National Instruments features."

  However, I still have some doubts (where the post with respect to the following:)

  -If I want to use the meter as trigger for both cards do I need to export to a PFI line and connect to the Member of the Board?

  -I do the same thing with the clock signal (export to the other panel using a PFI line) or using the same frequency for two meters is enough? Or both?

  -can I use the same value for the frequency in the meter and two clocks?

  Hope someone can help out me.

  If possible, underline some examples or detachment would be great.

  Thanks in advance for the help!

  See you soon!

  Hello

  All points depend on what you need to synchronize exactly.

  As you have probably already read in the links you provided, you have the option to share a trigger, or a clock, or both.

  Of course, the best solution is to share together.

  Then, you can choose to directly share the sample of one blade to the other clock (if the two sampling rates are the same), or to move the reference clock, then, both cards will synchronize their sample (with PLL) clock on the same reference clock, as shown in the synchronization M with LabVIEW and NOR-DAQmx series.

  Exactly how you want to use your meter?

  You want to generate a single trigger pulse?

  Then, for examples of synchronization, there are some zip files at the end of the links that you have read.

  Kind regards

• USB-6289 DAQmx delay early in the program

  Hello! Anyone help me with this problem.
  I have a new data acquisition is USB-6289.
  I'm only looking for I multiply by a decimal factor, after putting this result on AUG.
  for example
  AO0 ai0 * x =
  I want to do in continuous mode and in real time, with minimum delay. When I start the program, I have a time delay which varies.
  How can I measure this delay time?
  Anyone have an example of program to do (a simple multiplication in real time) and check where I have my mistakes.

  Thank you very much.
  Jonathan

  I put my program and a few cards of my oscilloscope (ai0-signal ao0 drop signal)

  Hi Jonathan.

  The code that you downloaded was not in parallel. Flat sequence structure forces the process to the AO HAVE to wait for the update panel. You can use the "Acquisition and recording of data" model to Create... Project for a reference on how to separate the update of the user interface of the real transformation.

  However, you must keep in mind that it is not possible to "simply to acquire a signal, multiply it and transmit" with DAQ hardware. This is because you must proceed as follows to get a signal and send it through the AO:

  1 acquire the signal in the DAQ card.

  2 send the signal to the computer via USB.

  3. ask the OS and LabVIEW process the signal to multiply.

  4. send the signal via USB in data acquisition.

  5. the output signal.

  This means that, while you can probably reduce the delay, you will always have this delay in the order of milliseconds. If you really need a shorter delay, you have a few options:

  (1) I noticed that the signal you're reading seems to be periodic. If it is a periodic signal, you can enable the regeneration in the AO and drastically reduce the delay, like the acquisition of data will just get the waveform periodical and cycle it. However, if the waveform changes, you will have some glitching.

  (2) use a multiplier circuit separated instead of data acquisition.

  (3) use a FPGA or RIO device instead of data acquisition.

  I hope this helps.

• Fuse with iGroove, speakers, USB connections

  I did a lot of scanning on these boards, try to understand something, I hope someone can help me.  (I see a lot of suggestions for Jerry-rigging through the headphone jack, which is unacceptable...)  I bought a Klipsch iGroove for out sounds mp3 on deck this summer.  I plug my fuse and receive nothing (no sound).  It is not supported, either.  I thought it was a bum unit.  So today I tried to play my fuse in my G37 cable 'iPod' resulting, and the car does not recognise anything being connected and of course no noise.

  So, you can play music via the USB cable?  The question is not really on the cable, it's the location on the device.  Think of dock.  Can connect to a set of speakers and have it reload everything by playing music on the speakers?  Even if it does not load during playback, it can even play music out of the USB slot?  Or should I return this thing and get something that can?  Any help would be appreciated.  Thanks in advance.

  It takes a SANSA compatible dock like this for it to work. Purchase of a dock that is compatible iPod will NOT work, the plugs are similar but are very different. If hold you onto an ipod docking station don't be supprised when frying your player when you try to load it. Why use the socket for headphones, a problem, there are many speaker systems that sound the same when you connect to the headphonejack as you do when you connect to the USB port, infact if you find a "Universal" dock that is how you hang you so it's not "Jerry-rig" anything the way they are designed. If your concern is the battery life and you can't find a compatible dock Sansa, try a universal docking station and a power adapter with the connected USB cable on what he's going to play. It plays when connected and charge but only with a Sansa compatible dock.

  Hi slithytove,

  Thank you for using communities of Apple Support.

  I see that you have added a friend on your Apple Watch to share activities. On your Apple Watch you don't see the results of your friend, but you can see the you and the results of your friends on your iPhone. They see your activity on their iPhone as zero.

  I just started using this feature myself. Watch OS 3 is really cool in how it allows you to share your activity with friends and family rings. I'm happy to help you with this problem.

  Please ensure that all iPhones who share the activity are connected to the Internet and signed in iCloud. Use article share your activity with your Apple Watch, more specifically, this section:
  
  

  Get help with sharing activity

  Activity sharing requires iOS 10 and watch OS 3. If more than one Apple Watch associated with your iPhone, the sharing tab appear not in the activity until you update all your watches to watch OS 3.

  If you are unable to add a friend, make sure you have a Apple Watch and that you have not added the maximum number of friends. You can add up to 25 friends.

  If your iPhone can connect to the Internet and you are connected to iCloud, you can get the updates relating to the activities of your friends every day. If your iPhone can not connect for several days, or you disconnect from iCloud, you may see missing days.

• My old iphone 6s is completely broken, it does not or registry that it is connected when plugged into a computer. I'm able to recover photos from the SIM card with an adapter USB SIM card or through any other way?

  My old iphone 6s is completely broken, it does not or registry that it is connected when plugged into a computer. I'm able to recover photos from the SIM card with an adapter USB SIM card or through any other way? I also do not save anything with AllAccess, icloud, or through my computer as you would with a digital camera.

  The photos are not stored on the sims, sorry.

  You can always try the Recovery Mode, little to lose at this point. If it doesn't, I suggest taking it to an Apple Store for testing.

  Recovery mode:

  Turn off your iOS device.

  Plug charge cable to the computer only (not to the device yet).

  Open iTunes on your computer.

  Hold the button to power on your device and do not let go.

  Plug the cable into the device while keeping the power button.

  Wait for the computer to detect the device and wait that he eat.

  Restore as New first, then restore sauvegardΘ if you wish.

• Satellite A300-19 q - how to start with an external USB drive

  Hi all!

  I have a (old) TOSHIBA Satellite A300-19 q bought in 2008. I wanted to do a clean install of Windows 7 by reformatting my HD. The problem is that my internal DVD drive no longer works. So I tried to boot from the Windows 7 DVD installation with an external USB drive.
  Unfortunately, I couldn't find a way to boot from USB devices in my BIOS options.
  My BIOS is up to date (version 4.20) from Toshiba Web site.

  So I was wondering, does anyone know if the A300-19 q can boot from USB devices?

  Thank you in advance.

  I have A300 at home but I never tried to start with an external USB device.
  Start your laptop and press F12 to get into the boot menu. There must be USB option. What happen when you try to use it?
