VISA problem read: after a while the device stops responding

Hello world

I am faced with a really strange bug than anything I've done him could not solve. I have a camera that I made myself communicating with LabVIEW by a RS232-> USB converter. Everything seems to be ok, but all of a sudden (it can last 30, 45 or 50 seconds), judgments of LabVIEW and data reception, as well as other buttons are no more, not even the stop button. I have to remove the usb converter to get the buttons answer once again, and then I got the error:

Other programs that opens this same terminal can communicate with my camera for hours without errors. I have of course the session open and close only after the while loop. Can someone help me?

How fast your VI reads the com port?... could he try to read too fast?... Add a waiting in your VI and see if that helps.

Just a thought...

  • Multicard reader W540 disappeared from the Device Manager

    I just got a brand-new W540, used the DVD that accompanies him to the level of W7 to W8 and then updated to W8.1. It works fine, but my integrated memory card reader doesn't seem to work. I tried to download the driver of multicard reader O2Micro W8.1 compatible web-support Lenovo, and he asked me if I wanted to repair or uninstall; to which I replied "fix." The process is finished, I rebooted upon request, but still the card reader does not. Or I see in Device Manager, and I did not all devices of unknown type or problems and manually install the driver (as existing device, using 'Have disk' etc) did not help.

    Searching on the Lenovo support web, I also found a Realtek driver multicard supposed to be done for the W540, but this does not work either. Both packs driver install without a hitch and lies in programs & applications after installation, but the rest useless memory card reader. I went straight for an OS update when I got the computer, I have no idea if the card reader used to work in Win 7 or vanilla 8 win, but I * think * I spotted under 'Storage controllers' before you try to install these packs pilot (but that could have been on another computer).

    Any ideas?

    As a last desperate resort, I ran an update BIOS and for some absurd reason the SD card reader on my works now W540.

  • J4580 print cartridge problem: [Tri-Color] refer to the device Documentation

    Well, I'm starting to feel like I knew better, buy another HP printer after dismal luck with two all-in-one before.

    My J4580 already gives me headaches after only 6 or more months of use.

    The unit refuses to print, declaring "print cartridge problem: [Tri-Color] refer to device Documentation to troubleshoot."  Nothing in the help documentation.  The Habs is always 90% full.  Sometimes pulling the Habs and placing back in crazy wil it restarting.  When it restarts, it prints perfectly.

    I tried the ubiquitous "clean the contacts" and other instructions help generic that I saw, but those who were without help.  The "Solution Center (Yes, good)" appears and all ithas is a link to buy more ink (!).

    Someone has an idea?  I'm about to throw it through the window of stores office, given that I can't throw it out the window of HP.

    Thank you!

    Yes * I know * and I'm sorry that I forgot to come back here.  I had a major system crash and I had to reinstall a lot of drivers for my multimedia player, GPS, and printer (!).  As this occurs, the device did not return this error - touch wood.

  • All the devices stop, while the computer is unattended.

    Recently at random, all devices stop working and I have to manually restart the computer, the mouse no longer responds, keyboard stops and the monitor says there is no signal, I unplugged and restarted all of them and run a scan and Defrag virus. I have also diagnosed the material and check the drivers and all seems good. This happens more frequently, but never while I'm on the computer as long as it's the mode 'sleep', I think. Food would be bad or what else could be the cause? It is a HP pavilion 3120

    Thanks for your reply,

    I noticed that the computer seems to be running much hotter than normal, I opened the box and the cooling fins were clogged with dust. I cleaned it up and see if this corrects the problem. I hope it's something as simple as that. If this isn't the case, I'll try the steps mentioned above.

    Thanks for your help!

  • OnLoad does not start after you restart the device

    Hello

    is it possible that "onload" in the body section is executed when the application is actually open?

    What I've noticed is when the device is restarted and the app is started after the boot process, then I need to open the application until something works. Is this as expected?

    Is it possible to run that a hat of javascript function will be executed after the application is started after a reboot?

    Thank you.

    I think you need to add

        
    

    in your config.xml file where the file name is the file that you want are running in the background.

  • Lack of Smartphones blackBerry messages (e-mails) after re - initialize the device through BES

    Hey there,

    One of my colleagues got just his BB and indicating the device simply synchronized or him remove the profile. Lack of contacts, emails were gone, schedule meetings missing etc... I have connected to our BES server, set the password activation and pushed to the device. I have connected since in the device, recreated his e-mail account of company and all seemed to have finished initializing. Noticed that the zone has taken time to initialize loooooong. I checked the time and date and both were correct. I checked his contacts, schedule meetings and everythin seems due back again all its e-mails are not returned. I sent many emails internally within our network of e-mail and outside my test hotmail account and unit did in fact bring but only after the re-initialzation I did this morning. Whatever it is before today was not returned.

    Any ideas?

    Thank you

    It is likely that his unit ran down on the memory and delete the data. But there is no "unsync" from the server. When the unit is short of memory it will erase the data in order to continue to run.

    The reason for which old emails did not return when you activated on the BES is this feature only works when you add a new device (new pin code) on the account, or if you delete and re - add the account. If you simply re-enable the device even on the BES you won't get old emails filled again. If you Google the mail in question you will find there is a solution but, if I remember it's kinda a hack of the BES to operate.

    Here are a couple of KB which deals with the issue of the mail:

  • After the updates of windows, the computer stops responding with a black screen at startup of the system

    Original title: Windows XP does not start after the update, no error message

    Has made no changes to the system, but the last thing that happened was an update of Windows security on stop.

    Now when I boot, the BIOS p.o.s.t. shows good HDs, good DVD-Rom, RAM, but Windows never starts, goes just a black screen, HDs are not accessed.

    -F8 does nothing, can't use the last known good Config or Mode safe

    -Change boot order in the BIOS to boot from the Windows XP DVD, hoping to get the recovery console, but the same thing: black screen, no attempt to spin-up DVD or HDs.

    -Removal of mobo battery to reset the CMOS, no joy.

    -Checked and re checked all connections inside.

    -Stripped devices and added one at a time, no joy.

    -Traded-in an old video card in case it was difficult to generate the higher res gfx, no joy.

    I was construction/upgrade / repair my own PC for 3 decades and can usually solve the problem and fix it myself, but this one me completely baffled.

    Any suggestions?

  • TBird causes the computer stops responding.

    TBird 38.1.0 (automatic update on), Lenovo T61, Win 7 Pro (auto update on), Microsoft Security essentials (automatic update on).

    Problem started a couple of days after, add a calendar on (lightning?) had installed without authorization or request. TB started, but then PC unresponsive shortly after. A message or two can download before the full stop. PC must be turned off using the power switch.

    From TB in SafeMode with shift seems to restore normal operation. By using the safe mode start, all the addons have been deactivated and deleted. Or at least I think.


  • Shared variable problem reading after deployment

    Hello

    I tried to create an OPC client to communicate with a server KUKA. I have a project with an i/o library configuration server. When I run the project, I can perfectly read/write my variables using the Distributed System Manager. If I put all the variables, I can read the correctly updated value at the server end. However, as soon as I start a VI that contains variables (which deploys them automatically), everything stops working and I can not write them to the VI or the DSM.

    I would be very happy if anyone knows how I could handle it.

    Best,

    Glauber

    OK, so it seems that the problem was that the request from the client to the server rate was too high. I added a wait on the loop that r/w, the variables and now this works. There is no need to be a single writer, and the autodeploy option can be.

    in any case, thanks to those who responded to the message.
