• Data drops using reading series visa

  I'm having a problem using reading series visa when you transfer a picture from one PC to another.  Writing PC transfers data systematically as seen by the probe on the chain get into writing.  Exe read the string displays however the string table once and then on the next reading displays an empty string.  It seems new and fourth without a complete data string and an empty string.  The vi that data comes displays a table updated consistent but the exe read the matrix (via RS 232) switches the vacuum to the full establishment of the loop rate which is fixed at 1 Hz.

• 700 - 147C envy: cannot change bios to boot from backup USB Acronis. Startup command problem

  I tried to boot from my USB Acronis boot device to clone my C: drive to another HARD drive, but I was unable to set the boot order (first USB) because it keeps resetting & put the USB back where it was before.  I've done this before without problem; I wanted to boot from an external USB Acronis rescue disk & run the procedure to clone of it. The USB is listed in the startup as list "Sandisk Cruzer 1.27 & it's the ISO boot Acronis on this file but I failed to get the pc to boot from it.» (not this time in any case). After a needless frustration 3 hours I ran successfully clone of C: drive procedure.  I checked the clone by disconnecting the source & boot from it, but it works "BOOT PXE ON IPV4 followed by PXE BOOT ON IPV6 before it starts the clone. The startup disk is listed before the lines of IPV in the bios then why what is happening?  I disabled the 2 procedures of IPV with F5 & now it starts normally, but I do not consider this problem solved, because I have not yet able to boot from USB & I don't know why I had to disable these 2 lines.

  Addendum: I revisited the right bios & reactivated 2 disabled lines & it is now booting properly, no nonsense IPV. Go figure.

  Help!

  I've seen similar problems before.  I solved me my clearing the CMOS and then start with only a UEFI (the main HD) compatible device. After that the problem had gone away, I reconnected it and then my other active UEFI device.

• How to stop the series 'VISA read' the sends packets instead of bytes available.

  Dear Labvillians,

  Highlights:

  How can I stop series "VISA read" send me packages rather bytes?

  Background:

  I have a system which publishes series of 14 bytes on a semi-regular interval packets.

  At busy times, the producer of these these queues of data packets, effectively producing Super-paquets multiple of 14 times larger than 8 packages (112 bytes) bytes.

  My protocol handler is designed to process bytes, packets, or packets Super.

  Now, my request has multiple devices and the order of message processing is essential to the proper functioning.

  My observation is that read VISA waits until the end of a package / super package before moving the data to the application code. (See chart below)

  My expectation is that VISA read should give me bytes available, get too smart for itself and not wait for a package.

  

  .

  

  I noticed this on PXI, PC shipped, PSC and, more recently, cRIO

  I've experimented with Scan interface the cRIO rate, which helps to reduce the backlog of packages but don't decide to package under read byte.

  I understand that a solution is FPGA code write to handle and pass the bytes by R/T-FIFO, and there are some great examples on this site.

  Unfortunately, it does not help with FPGA devices not.

  I have also dabbled in the event based sequential reads, but he is evil on vxWorks devices.

  Any help is appreciated

  It is helpful to sometimes talk to yourself.

  

  

  I hope that is useful for someone sprinkle in the future

• LaserJet Pro P1102w installation problems - USB not recognized during installation

  Struggling to configure the P1102w - using the installation DVD that accompanies it, I go through the steps. When I get to ' turn on the printer, connect the USB cable to the computer ' the printer is not recognized. Is not dismiss it, he just can't get it - it is with Windows 8.1.

  Tried it on another laptop running Windows 7 - same problem. The installer sat on the market "in waiting to connect to the printer via the USB port.  When you connect, Windows recognizes a USB device and tried to install the device - came with an error that could not be recognized and need to contact the manufacturer for the installation files.

  Update Windows, computer rebooted several times, deleted the HP installation files and tried with drivers downloaded from HP website - same problem.

  Any ideas?

  I had the same problem when working on a clients computer.

  (1) it has been infected by viruses, so we had to make a Virus removal on his computer.

  So you want to make sure that your computer is virus-free

  (2) in most Windows 8 HP computers in particular, drivers automatically installs on the computer.

  Check your device manager and click on printers. It will show what is connected.

  On my computer it shows printers >

  I had to uninstall it, to install the software. Once I did that the computer was able to recognize the USB cable.

• After reset, problems of internet connection due to problems during installation of updates

  Original title: recently reset computer - internet connection problem

  I used hundreds of gigabites and most of it was unknown, so I decided to reset my computer and do a clean install. He started very well, the instalation process.

  But once I jumped on the desktop, I noticed I could download windows updates, but not browse the internet. Just of left me with a white screen without end and says "waiting for google.ie" solve problems no problem, this isn't even not aware that there is a.

  I finally just hoped windows update could solve this problem, so I tried to download and install all updates. He failed and left me in an endless loop of "reboot...". "until I restarted my PC 3times to reboot and installed an other clean.

  Then everything seemed fine, I could browse the internet immediately. I downloaded google chrome, traveled to youtube and finally installed Norton internet security. But when it restarted, google chrome would not meet any time I started and internet explore doesn't load pages, just like before.

  I installed the 100 pending updates immediately, and the problem persisted. It can always downlosd updates to windows, but won't let me access the internet. I really need help, it only happened on this computer before. It may not be a problem with my modem, he's always been compatible

  Installing another batch of updates - 9 of 95...

  This problem is fixed after this last batch of updates, if I were to turn off manually the update screen because pc had glitched. Windows is full of unwanted confusion today

• Writing series visa delays

  Hello

  I use the LabVIEW Vi series to send commands to a DUT. I use the a Sparkfun USB to Serial converter cable for the interface, by connecting directly to the TX and RX pins of my DUT (an MCU). I am able to send and receive data without any problem or data corruption, it is really slow.

  There are up to a 5 second delay between writing the message get written in series VI write and actually see me this post to the MCU. I have a scope attached to the TX/RX signals to see when this happens. Fortunately I do only 2 entries of 4 bytes, so there is only an additional 10 seconds of delay, but with it, wrapped in a teststand sequence, delays will be added through hundreds of iterations.

  Anyone seen this before? Any ideas what I might be able to try?

  Thank you.
  Mark

  Well, the post was premature. A co-worker pointed out my mistake.

  I use 2 queues, one for reading, one for writing on the port series. The problem is that I use the VISA Read.vi timeout for reading queue loop and the Dequeue Element.vi for writing loop. By chance, I had configured the read timeout set to 10 s. Given that the serial port is the same VISA session, these are not truly independent of queue loops. the function Read series was blocking the write function of occurring for at least 10 seconds. Once playback Vi has expired, the writing was able to sneak in and get the message written.to the port.

• Creating a string of bits to send through questions series VISA, complete noob here...

  Hi all

  I'm trying now, to browse the values I have on my collection of GUI and with these, construct a message to send through VISA.

  I have the usb-> rs232 cable and NO, and I have attached a connector, with the pins 2 and 3 tied together so that I can loopback and see the messages I send.

  I'm supposed to (from the instructions that I read on a design doc) will send a message of length of 24 bits.

  And please bear with me, I've never worked on this low a level before, nor with the serial interfaces, so I can be completely off on how I'm doing... and this is my

  first really relay with LabView for this project.

  I have some time execution of every 20ms in a loop.

  I have a structure of the event looking for user actions on my front.

  I also breast that everything in a loop, a flat sequence structure... my assumption was, every 20ms, the flat sequence structure would run, except where it is interrupted by an event... that could trigger and then continue with the flat structure...

  I have seen that the entry VISA (and read) take a string.

  So, I started the flat structure with build my string of bits/bytes outgoing... first section is coded hard and then, through the two sequences, loop it and based on the values of the controls within each cluster, I concatenate to my outgoing string... in which case, I send by the visa by the closure, and post it on the message indicator.

  It seems that I can send on only 8 bits at a time through VISA... so, I try to understand (and I wonder people with the req on this part) why they said to send such a long chain... or am I supposed to send each message of 8 bits, one at a time?

  If one bit 8 message at the same time, I wonder how I have let him know when I am finished?  I have heard and read things about start and stop bits, but I don't know where to put them.

  In addition, is the string that I'm supposed to put them together to send something waiting for data series bits/bytes? I saw a reference to a string of bytes while the research, but I Coulnd't ' t find a piece of string byte on the pallets.

  And when I run the present (a simpler example of my real application, simply to show here the parts I am trying to figure)... the message echoing again to me is:

  111000010000\n

  When if I have all the tubes with a value in them... I want to get something new like:

  1110000111111110111111110\n

  I'm also noting that messages do not seem to be transmitting every 20ms... seems only to get a message back when when I trigger an event, as the option switch on the LED.

  In any case, I'm confused, I think that, on certain basic principles and hope someone can maybe send me some links or give me some advice on where I'm wrong so seriously...

  Is my construction of the right to follow path string message?

  Is something wrong with the flow of the program... the events + flat sequence structure?

  I received this property by searching for forums and other papers OR, but I'm stuck sort of and confused I think on some concepts with read/writes...and possible VISA my flow control.

  Any suggestions and/or links GREATLY appreciated.

  Thank you

  PS. Some asked to record for older versions, so I enclose a copy saved to more 2011 v10

  Cayenne,

  Your sequence structure is not necessary.  You have a dependency on the data, as well as the structure of sequence is not really do anything for you.  Seems to me that what you want to do is to build the table of your clusters that you already own and send the table directly in a > 0? function.  It will accept berries and an array of Boolean output.  You can then use the Boolean array to the Number function to create a U8.  Do this for each of your clusters and integrate the results in a table of U8 and fixed data.  Then use the array of bytes to the string function to get a string to pass in the VISA to write it.  Without loops or the necessary structures.  Any additional manipulation you need, I recommend to the byte level.

• Sensor USB - RAW VISA MAX Sylvac

  Dear community

  I am a new user of LabView and I would like to read the data from a distance sensor Sylvac USB (see here for the link to http://www.sylvac.ch/index.php?page=shop.product_details&flypage=flypage.tpl&product_id=201&category... sensor).

  When I use the software provided by Sylvac, no problem everything works fine.

  Note that it is not possible to create a secure Channel as Sylvac does not provide drivers for this particular sensor unlike this post http://forums.ni.com/t5/LabVIEW/How-to-read-out-data-via-usb/td-p/2042980 .

  I created the driver NI-VISA following this procedure (Assistant of the Driver NI-VISA)

  http://www.NI.com/white-paper/4478/en/

  In the MAX, the sensor is correctly detected.

  With the help of a Cokehead USB (USBlyzer) and using Sylvac software and drivers, I found that the software sends a command for the sensor to apply for the position (? \r or 3F 0d in HEXADECIMAL) and the sensor to respond by sending the position (see attachment for USBlyzer report).

  When I do the same thing with MAX test panel and drivers of NI-VISA, I am able to see the 0d 3F, then the 2-byte buffer, but no return of the sensors (see attachment).

  Anyone know what I am doing wrong, or what direction I should look for?

  Thanks in advance

  Best regards

  Florian

  I finally "solved" the problem by changing the sensor with the USB to one with RS232. Thanks for your replies.

• Money from Microsoft 2003. USB key to the high problems.__Windows Vista.

  I usually backup Microsoft money to drive flash usb without problem. I just bought a new larger Lexar usb flash drive that works perfectly with all the other functions/programs outside Microsoft money. It backs up the data so then he said to put in the next floppy disk. I tried to format the flash drive in various formats, but it still will not be considered like a flash drive. The flash player works fine in all other aspects, but it seems to be a problem with Microsoft money recognizing the drive. All responses appreciated

• * USB ports and my printer problems

  My laptop is Windows Xp edition sp2 family.

  My old HP laptop computer of 4 years has 4 USB ports. Unfortunately, 3 of the 4 ports broke physically, so I only have a single functional port.

  A port that works cost of my cell. So I know it works. But now, only 40% of the time it will print when I plug my 750 HP printer all in one in it.

  Otherwise, it will display a "?" on the printer in the taskbar icon. Once, I unplugged the USB cable and plugged into the broken USB port holding it still and it actually print my papers.  But as I said I have been lucky that day cause these 3 ports are broken.

  What can I do to make the only port 1 have, can work for all devices I. It seems not only act with the printer.

  In addition, supplants ports broken something painful, costly or difficult to do? I know it can vary depending on the brand of the phone... But overall, it might be an easy solution?

  Thank you all in advance...

  I have created a key to reset Windows 7 password on a USB key according to the instructions. When I tested it, the computer he labeled as being in drive F, but he gave only the insert options in the G or H drive. The only way I could make it work was to use two players to jump. Then he would see the reset key in the drive I have and I would go forward. How can I fix?

• Without end error App 606 torch reset problem

  Hello

  I am developing an app for the devices RIM supporting the OS version 4.5 and 4.6 +.  In my 4.6 + branch, I ran into a huge problem with this binary file on the torch on the last two official versions of the OS (6.0.0.246 and 6.0.0.449; Versions of Rogers).  Code is built using JDE 4.6, signed using the private key of my company and the RIM SDK buttons.

  If my request is properly installed (loading cable using javaloader - no previous version installed) and as long as it normally stops before the reset, I encounter problems.  If I installed a previous version using javaloader, or I pull the battery when the application is running, the machine can finish is no longer the boot process.  The torch passes through the full operating system loading process, and everything as network connections begin to come to the top and before the coming carrier screen, I get an alert saying "Eception exception: NullPointerException", another alert saying "Eception exception: java.lang.Error" and then a white screen saying "App Error 606" and a line below to say "Reset".  After reset of the device this ever again, no matter how many times I reset.  The device is actually brick until you force remove my application using javaloader, after which, the unit returns to the normal operating state.

  This problem does not occur if the application has not been used (I can install over it as much as I like, as long its persistent store has not been created).  This leads me to believe that there is a bug in the implementation of permanent storage in these OS versions.

  Attach the debugger through the startup process gives a large number of unknown uncaught exceptions during the final stage of startup (several hundreds).  The most interesting part of the log, contains the following debug messages, probably from the implementation of the Application Manager.  This is repeated several times, indicating that the AM cannot go beyond initialization after several attempts to start and dies by timeout in an unrecoverable state:

  AM: Started net_rim_bb_browser_daemon(300)
  AM: Exit net_rim_bb_browser_daemon(300)
  AM: NullPointerException
  AM: No detail message
  AM: net_rim_bb_browser_lib-3(4D389E92)
  AM:  BrowserDaemonRegistry
  AM:  
  AM:  0x226F
  AM: net_rim_bb_browser_lib-3(4D389E92)

  AM:  BrowserLoader
  AM:  main
  AM:  0x81
  ApplicationManagerImpl.processExited : process process switching to background:  pid=300
  

  I'd be more than happy to send a replication mechanism binary and full of a person on BOARD to help solve this problem.

  I solved the problem and I thought that others here could benefit from my experience with this.

  In the code of my Persistent Store app, I was stretching from ContentProtectedVector and ContentProtectedHashtable and marking these as Persistable classes so that they could make in the persistent store.  For example:

  public class Attributes extends ContentProtectedHashtable implements Persistable
  

  Neither the compiler nor the JVM complained when these classes have been committed in the persistent database, and they behaved properly on simulators and devices with OS versions 4.5 - 5.0, without any problem.  Versions 6.x BBOS will accept this code as well, but on a cold (battery pull) start, I got the following error in the log (id and package name changed to anonymize my organization signatory):

  CMM: net_rim_cldc-11(5967) no sig from 0xFFFFFFFF
  module 5967 cannot reference com.xxxxxxx.client.model.Attributes
  

  While the API seems to confirm this, something in the cldc seeks to inspect the store persistent on cold start, and it seems to fail when it encounters an object that is a subclass of a Persistable class pre-existing and Persistable.  If this behavior is that it should be in the documentation Persistable and all classes of the RIM that implement Persistable.

  Since the current Persistable JavaDocs:

  A class must explicitly implement this interface for the system store instances of the persistent class. Subclasses inherit any implementation of this interface. In the following example, Bar instances may persist, because the class does not explicitly implement the Persistable interface (if you try to store an object of bar in the persistent store, the camera fires a JVM error):

  This seems to imply that extend a Persistable class and Persistable implementation is the path provided (for example, if you do not want to stock the bar from the example of the JavaDoc).
