• Camera HDR-AS50 disconnects right after that QR Code is scanned

  Hello

  I have problems connecting my new ActionCam AS50 on my Android (Samsung Alpha) phone.

  Steps to follow:

  (1) first of all make sure that WIFI is on in the camera.

  (2) then I scan the QR code.

  (3) it asks me to connect. I say ok

  (4) it is said connection and turn for a while.

  (5) then he said: DISCONNECTED or failed to CONNECT.

  How to make this work?

  You scan the QR - Code and then go to the settings of your phone.

  Search you for WiFi hotspots and select one that has your camera model name in it.

  Then, you paste the string of letters and numbers in the field password and connect to your camera.

  After that, you open the application again.

• QR Code pop camera to scan problem

  Hi, I'm scanning the QR code with my code. My code works well with OS 5.0 phones (Bold) and 7.1 (Torch). It works well with 7.1 and 5.0. but give problem when running with 6.0 OS (Bold 9700). The problem is - "so that the attempt at analysis of QR code, app scans the QR code but the device screen is not pop and remains at the front. Event, that is not able to hide using the ESC key." Please help me to solve the problem with os6. Ankit

  Hi all

  I solved my problem for os 6. After the sweep of QR code, close all the connection reader and scanner.

  Used-

  If (_scanner! = null & _scanner.getPlayer ()! = null) {}
  _scanner.getPlayer (). Close();
  }

  It is useful for me.

• Error - 410 after scan

  I'm programming a Keithley SourceMeter 2430 to run a scan. Using a similar code to scan no I've never had a problem. I run a scan on the GPIB-USB-HS. First time works fine, but when I try to get a second series of readings, I get the error of request interrupted-410. If I restart my software can I get again a series of measures before the error. I fought with this for a few days and I need help.

  Here is my code.

  Thank you

          readString = InsertCommonEscapeSequences(ControlObjects.Keithley2430.ReadString())
          VI = Split(readString, ",")
  

  The two problems are solved now. I found that if I put any of any delay, readstring somehow made a statement break the vb code until the scan is done.

• scan with ni9401 mode

  Hello, I use the scan mode and the module ni9401, and I'm under codes in labview with a timed loop

  When I try to change the loop timed to dt = microsec and scan period<1ms in="" compact="">

  Compact rio is disconnected! why I got this problem?

  Maybe I can use scanning with scan time mode<>

  Hi, mariomoskis,

  Unfortunately, this is part of the limitation of the scan Mode. You can basically think of scan mode as a train that toured all the modules collects data and it falls on the drive and there is only 1 train for the entire system and it runs at a speed (scanning speed). The fact train one passes each interval of scanning speed, so if you want to produce a train of pulses to a little less than 1 kHz you will get aliasing. However, cRIO should unplug any, I don't know what the problem is here, but it seems closely related.

  There are two solutions to this problem, but the two would require changes.
  1. you can avoid all these problems and the resolution time get down to a 25ns (or less) If you set the mode FPGA. We can use the existing code of NI.com/IPnet to implement a pulse generator to train with the custom calendar settings and pulse on any module.

  2. some modules support digital modes specialized, making essentially a pre-built section of the FPGA code (in scan mode) that support some common functions such as Pulse Width Modulation. With these modules, you can request a rate (which will update at 1 kHz)-specific, but the actual timetable for the module is managed at the hardware level. There are only a few modules that support it, and they are listed in the link below.

  I hope this helps.

• LaserJet 400 colorMFP M475dn: my printer will not scan

  The printer worked perfectly for yearsnuntil today when he not scanning to an e-mail saying: username or password is incorrect and to ensure the user name and password are valid. I never set up with security by password. I read the entire manual and cannot figure out what to do. I'm desperate, since I use this for my work. Thank you very much!!!

  Hi Helen,

  We gladly invite you.

  Please open the printer homepage, to open it click on the Configuration icon on the screen of the printer and select reports, then tap report Configuration to print a report.

  Locate the registered IP / IPv4 / URL in the network information section, then go to the URL from the web browser on your computer...

  Click Scan in the main menu, and then click e-mail profiles outgoing in the button left of andclick pane change to the active scan profile.

  Updated the SMTP password with your new password, check that the PIN in option values empty unless you do not want to set a 4-digit code to scan from the front panel (sometimes, the browser can automatically fill these).

  Click on save and test, and then allow the test complete the scan to e-mail function should work again.

  Kind regards

• barcode analysis code

  Hello

  I want to develop the qr code barcode scanning in blackbery.

  Please help me if someone worked on it.

  Thank you

  It provides only QRCODE;

  You can add all formats: replace here:

   Hashtable hints = new Hashtable();
   Vector formats  = new Vector(1);
   formats.addElement(BarcodeFormat.QR_CODE);
   hints.put(DecodeHintType.POSSIBLE_FORMATS, formats);
  

  as:

  Hashtable hashtable=new Hashtable();
  Vector formats=new Vector(10);
  formats.addElement(BarcodeFormat.QR_CODE);
  formats.addElement(BarcodeFormat.PDF_417);
  formats.addElement(BarcodeFormat.CODE_128);
  formats.addElement(BarcodeFormat.CODE_39);
  formats.addElement(BarcodeFormat.DATA_MATRIX);
  hashtable.put(DecodeHintType.POSSIBLE_FORMATS, formats);
  

  that way, you can add all Blackberry barcode formats provided by blackberry. and run the application;

• My CC InDesign generated QR code reveals the empty email address

  Good afternoon

  When I generate a QR code in InDesign CC and set the specifications for a recipient to scan email, it does not have the email address I identified in the box "edit the QR Code. This happens with several different readers of QR. Am I missing a step?

  "E-mail QR" flavor which creates CC seems to be the MATMSG format. According to zxing.org, your image decoding without error

  MATMSG:
  TO:[email protected];
  SUB:Wouldn't Miss It! You guys rock!;
  BODY:I'll be there.;;
  

  and the QR code scanner that I use correctly opens a new mail with these information fields. So it seems that it is just a problem with your "QR readers several different".

  That is to be expected; the QR code standard is for plain text, and there is No standard to 'read' as Web Page, telephone number, E-mail, or other. There are only a few conventions, such that "this text begins with http:// , it should be a web page. Your example decodes correctly, so at least IDCC follows the format MATMSG by creating the QR code. But that doesn't say anything on decoders that may be using your users.

  There's another way to open an e-mail, but is no guarantee that it will work with your QR readers or those of your customers (of course!). Try this; Enter plain text and make sure that there are no hard returns or spaces inside. The lines have been broken to make it fit on the screen.

  mailto:[email protected]?subject=Wouldn%27t%20Miss%20It%21%20You%20guys%20rock%21&body=I%27ll%20be%20there%2E
  

  The result is this QR code. Scan to see if your player now creates an e-mail.

  

• IV curves

  Hello

  I need to make a program using Labview to obtain IV curves when the characterization of solar cells.

  I have two engines that move in the direction of X and Y. choose a Y, the Xmotor moves a distance regulatory and stops at a time determined by a series of steps. What I need is to add the IV curve measurement in each of these steps. I Keithley2400 drivers, but I don't know if it would be better to use VISA, no idea how to do this? (it s the first time I will use resources VISA or similar)

  Thank you very much

  You'll find plenty of screws in the related forums the 2400, swept some of them specifically for IV (with the drivers or VISA).  I posted a piece of my code to scan IV here before...  http://forums.NI.com/T5/instrument-control-GPIB-serial/how-do-I-set-a-source-current-and-measure-the...

  I find using VISA provides a little more freedom in communication, but of course, it can lead to more errors.

• How to insert the PIN by E-mail of the documents

  When you try to e-mail a document, the askes of screen for my PIN, which I am, but how do you I insert it with no keyboard?

  Hi @cyclops2,

  Thank you for taking the time to answer my questions.  It is appreciated.

  The Photosmart series 6520 printers have a touch screen, when you are prompted to enter the pin code for scanning to e-mail, please type in the field to display the virtual keyboard, then you can enter your PIN.

  If the virtual keyboard doesn't show up when you press the field to enter the pin code, then please call HP Cloud Services at 1-855-785-2777 if you live in the USA/Canada region. If you do not live the USA/Canada region, please click here to find the number of Technical Support for your country/region.

• analysis of the chain does not recognize the AM/PM indicator

  Hello

  I'm using Labview 8.6. I want to parse a time string, with an AM/PM indicator on the inside, but the format of time code 'string scan. '

  "%<%d/%m/%Y % I: % h: %p %s > T ' does not recognize the AM/PM indicator. The other strings contains the AM/PM indicator.

  Best regards,

  Is the solution:

  define the symbols AM and PM in the control linguistiques\Options settings\time Pffffffffffffffffffffffffffff

• Magnetic lock Lenovo A1000

  Hello world

  How long are allowed to try out the code by scanning on smartphone Lenovo A1000 before it crashes all the time?

  Yes, I forgot my code to hit.

  Thank you very much

  Hello

  I still don't know how many tests are allowed before the phone 'locks '... BUT... I tried more than 50 or 60 times and he has not yet locked.

  If Lenovo had allowed allows you to see the shot as it happens, (change from blue to red when the model is incorrect, as do many other phones), we would have had it open now.
