Problem with the serial port and external DLL

Hello

I have a Platinum (innco systems CT 0500), which is connected via a USB-RS232 to PC Converter. I want to fight in LabVIEW.

The software CD contains a DLL and a header file - I imported both in LabVIEW.

But I am unable to get a connection via LabVIEW COM port. There is an error of the adage about function ConnectTurntable() return code 'could not open port - port address is unknown to the PC or port is used by another program.

The demonstration of the delivered CD software works - the connection to the COM port is working with him, so there must be a mistake in my LabVIEW Code.

Thanks in advance

  • 3 laptops different ALL been facing intermittent problems with the USB ports.

    We have 3 laptops at home, running 3 different versions of winsows 7... Home, Professional and Ultimate. They have in recent months ALL given intermittent problems with the USB ports. A device that worked on a port stops working. It may or may not work on another port. A week later it could very well lead again on the port that wouldn't work. This applies to all types of devices.

    A few more questions:

    Is there a USB device that you use with all three computers?

    This problem occurs with all kinds of USB devices?

    The is the problem with all the USB ports on each laptop?

    Have you tried to reinstall the USB drivers? As in, uninstall via the Device Manager, restart your PC and allowing Windows to reinstall?

  • Equium L10: Problem with the main battery and battery RTC

    Hello

    I have the Toshiba Equium L10 and it is about 14 months old and I have problems with the battery and how much time it takes after a full charge. I also have problems with the RTC battery and an ERROR 0271: check date and time settings message when I turn on the laptop.

    Regarding the battery, I can fully charge it upward in about 3 hours, but when I start to use it, apparently in the last few hours around one and a half or so and then it needs to be recharged. I can have down for about 40 minutes and then turn it off and come back later or in a day or two. How long should I expect from a fully charged battery?

    About the batttery RTC, it really becomes a pain and I only started to get the message of the ERROR 0271 start-up, in recent weeks. I can charge the battery pack and then leave for a few days, but when I turn it on, I get the message ERROR 0271 on the date and time incorrect. Surely after a full charge, the RTC battery should last longer than a few days?

    The manual says that if the RTC battery is exhausted or becomes weak, you must charge the battery of the CCF for 24 hours, in a different part of this manual indicates between 24 and 48 hours, but how can load you for long when the sections concerning the charging battery pack status after charging the battery you unplug the power adapter because leaving connected will shorten the life expectancy of the Battery Pack. So, how we can charge the battery of the CCF for 24 to 48 hours if we shouldn't leave the AC adapter plugged in once the battery is charged - which is nearly three hours. Suggestions about these problems would be appreciated.

    Besides we all know that it is easy to change the CMOS/RTC battery in your desktop base unit, but is it easy to change in a Toshiba Equium L10?

    Concerning

    Brave0

    Hi Brave0,

    The normal recommendation for the CMOS (RTC) battery is to leave the laptop connected to the power supply at least 12 hours when the main battery is fully charged. The charging circuit is going to hijack the current to the load automatically RTC battery and no current will be forwarded to your main battery.

    Recommendation do not leave the power adapter is plugged in the main battery is fully charged is really only applicable to older laptops that used no batteries Li - ion and therefore they had to be completely discharged before recharging to avoid any effect 'memory' of the battery.

    With modern Li-ion batteries, it is quite safe to leave the battery when fully charged and still power the laptop from the AC adapter. The charging circuit will pass all the battery charge if it is fully charged.

    Kind regards

  • problem with the Finder - files and folders displaying incorrectly

    After acquiring a new iMac, I noticed a problem with the Finder - files and folders are displayed wrong (see table).

    This is what happens always after the files have been transferred from one folder to another. I was reminded of my days of using Mac OS in the 1980s when automatic setting of files was not so "automatic." I use Mac OS for decades and I don't remember the last time I had to think about GUI problems like that.

    Other problems in the graphical display of files and folders were introduced, such as when you have hundreds of files in a single folder, you end up deleting about 30 to 40 of them say in a particular section, and you end up with gaps of the ChartSpace where files used to be, that is the remaining files automatically rearrange themselves (fill in these gaps) - never. A week later, you open the folder, and the gap of GUI is still there.

    I decided to do a clean install of the operating system but nothing works.

    Is there some setting in Prefs I'm missing?

    Hi there highland99,

    Looks like your folder icons are not accommodating themselves automatically you plan to do. To me, this indicates that you have organize by the None value in the view menu. You can change the way files and folders are prepared automatically by clicking on view > reorganize by and selecting how you would like that fixed.

  • I started having problems with the wireless mouse and the carpet of my laptop - Lenovo ThinkPad T420 mouse.

    Original title: right click on the mouse itself activating

    I borrowed a USB to a person at work and I started having problems with the wireless mouse and the carpet of my laptop - Lenovo ThinkPad T420 mouse. The left click of two devices works normally, however, sometimes she does not respond to clicks and it takes a few seconds to work. The left button was constantly starts to turn on, as if he was stuck. After that I hit Alt + Tab and modify windows it stops for a few moments and starts at a later date. I havo not found a specific condition or a combination of keys that may trigger the fault.

    I read a few posts on discussion forums, but all say that it could be a hardware problem, which I think is not, because both devices have the same problem and I'm sure it all started with the insertion of the borrowed memory stick. I scanned the readers to help Symantec's EndPoint Protection and installed Microsoft Security Essentials and performed a full scan, but found nothing. I even restored the system, but the problem remains.

    Should I get a different antivirus? How can I find the cause so I can find a better targeted solution?

    Try to install the drivers from this link and check.

  • I get the message: Photoshop has encountered a problem with the display driver and has temporarily disabled GPU enhancements. Visit the Web site of the manufacturer of the video card for the latest version of the software.

    Photoshop has been giving me the warning:

    Photoshop has encountered a problem with the display driver and has temporarily disabled GPU enhancements. Visit the Web site of the manufacturer of the video card for the latest version of the software.

    Also other programs are affected.  I suspect a recent download of Adobe.  Can anyone HELP.

    No, it has nothing to do with updates of Adobe. There is a problem with your video card driver.

    Go directly to the Web site of the manufacturer of the GPU for updates (not Microsoft, not a System Builder).

  • How to solve the problem with the wacom tablet and the polygonal lasso tool. It does not work with a pen.

    How to solve the problem with the wacom tablet and the polygonal lasso tool. It does not work with a pen. I have install windows 10 and fresh, new drivers for wacom bamboo, could he makes problems or there is a problem of photoshop?

    It should do.  You use one of the buttons of pen maybe?  Just touching wheels with the pen with no buttons or modifier keys.  Press ENTER to close the selection.

    Personally I never use the lasso, Polygonal, but rather just the Lasso tool by using the ALT (Opt) to operate the Polygonal tool.  I also use the mouse instead of the Tablet for the selection of cutting edge.  It is a little too uncertain where the point will go when hovering the stylus above the image.

  • Problem using the serial port with windows 7

    Hello

    I have a modem of SIM cards (used to update remote controller of the electronic gate) that connects to my computer via the serieal port (COM1).

    The modem comes with its own piece of software that worked fine on my old computer with windows 7 (I had a similar problem, but then I just need to update the driver).

    I now have a new computer and I am unable to connect using the modem (I think I'm using the latest drivers for the serial port).

    Is it possible that I need an older version? If so, how can I get a?

    My motherboard is a GIGABYTE H81M-D2V.

    Any ideas?

    Thank you

    AVI

    Hi Avi,

    Thank you for the update on the issue.

    The UART, or Universal Asynchronous Receiver / Transmitter, is a characteristic of your microcontroller useful to connect serial data (text, numbers, etc.) to your PC. The unit switches incoming parallel information (in the microcontroller/PC) to series data that can be sent over a communication line.

    According to the description you provided it seems that your modem isn't connecting with your Windows 7 computer, then I would contact Duetech Berès your modem manufacturer, so that they provide you with the steps to set it up.

    Get back to us after contacting them and please get back to us with your question was last updated.

    Kind regards.

  • When I try to record photoshop mi account, there is a problem with the internet connection and I can't continue. How can I solve it?

    I bought a book on Photoshop CS many years ago, and once I installed it in my computer it says I should I enroll the account in order to use Photoshop (or something similar), and it also has a link to go directly to the website of the registry. The problem comes when I try to access this link given, which is an internet link. It appears that my Internet connection is not secure, so I'm not allowed to continue the process, even if I don't really no problem with the connection. As I'm talking about an older version of Photoshop CD, the problem might be that something related to the incompatibility with my version of microsoft. How can I solve this problem, if there is no possible solution?

  • Did anyone else had problems with the serial number below MyAdobe does not?

    Try to re - install CS4 to work on something, and when I downloaded the installer and unpacked, it rejected the serial number on my page MyAdobe to the CS4 Master collection. Is there another number somewhere I should be entered or something?

    IF you are sure that you download the correct suite, you must contact Adobe Support by chat or phone when you have the serial number and activation problems.

  • Problem with the serial numbers on the laptop?

    I have CC on my desk at work with a composition of the team, I was told that I could use this subscription even on my laptop at home to work at home. However, when I downloaded the CC and the programs I need, whenever I try to open a program, it tells me I need a valid serial number, who said an administrator at work that it was not necessary and should be a problem with the other adobe programs I. I recently reformatted my computer and only Adobe products, I think I would have left perhaps are pdf reader and flash for Web sites.
