Can I change the default settings for the latency time Serial Windows with LabVIEW

I have a wireless data collection device that my business is that I am using for the test one of our other wireless products. The device sends data series to a PC via a USB port. I wrote an automated LabVIEW program to test all the functions of my new product. However, after firing in the data, I realized that the serial data coming very fast and requires me to change latency of Windows by default for the port COM 16ms 2ms Miss not nothing. It's pretty easy for me to do locally on my machine, but much more difficult for me to spec for an off-site CM.

Is it possible to have my LabVIEW program change the latency time of the COM Windows port of 16 ms to 2 ms automatically?

Are you talking about the FTDI driver? I know that they allow these changes through registry settings. Thus the approach would probably be to have a small registry script that updates the parameter of function. Most likely, this will have to be run with elevated privileges, as these parameters resident generally in the HKLM or HKCR rather than the HKCU one hive.

  • How can I change the installation directory in windows PC where to deploy the package to the series of licenses?

    I started to deploy in the victory of the client PC with command line like below,

    msiexec /i exsample.msi TARGETDIR = D:\test

    or

    msiexec /i INSTALLDIR = D:\test exsample.msi

    Installation was completed though, apps had been installed in the defalt directory "C:\Program files".

    In CC helps Packer said as the folliwings on the location of the Installation,

    "The Application Manager offers you the following options for the deployment location:

    Deploy in the default directory of the application: the player is by default the system unit; the default path is \Program Files in Windows/applications under Mac OS.

    Specify the directory for the deployment: allows users to end to specify the installation path when the package is deployed. On Mac OS, users are invited on the user interface, while on Windows, it's a command-line only option.

    ' Specify the directory: enter the path to the location to a specific installation location.

  • How can I change the destination folder to Windows Picture import in the Vista autoplay version. ?

    The destination folder somehow Autoplay went under the windows default 'Photos' parameter in a subfolder in 'Photos' when you use the option 'Import using Windows' Auotplay. Default AutoPlay program area does not choice for import folders, only actions to choose from. How can I change the default import folder back to 'Pictures' Autoplay when importing photos using Windows Vista import?

  • Very slow access to data on HP MIcroserver Gen8 warehouses. Can not change the system of booking resources with vSphere client.

    I did a clean install of ESXi 6 with HP supplied image (ESXi-6.0.0-2494585-HP-600.9.1.39-Mar2015).
    Access to and from the warehouses of data over network via vSphere Client (6.0.0 - 2502222) is very slow - ~ 10 Mbps (there are several hundred under ESXi 5.5)
    I suspect that ESXi 6 limited CPU resources used by the host to 230 MHz system.
    I can't change the settings 'System Resource Reservation"(unlike ESXi 5.5, where I can change and switch to Simple or advanced mode).

    Hey ArnisR,

    I finally found the problem. In the last 5.5 ESXi and version 6.0, they replaced the driver hpvsa (HP ISO vSphere!). With these drivers, I have known major problems with banks of data and, therefore, the controller B120i (RAID) of the Gen8 MicroServer HP.

    The problem is caused by the last (HP) ISO (from March);

    -Mar2015.iso 5.5.0 - Update2-2403361-HP - 550.9.2.27 VMware ESXi

    -Mar2015.iso 6.0.0 - 2494585-HP - 600.9.1.39 VMware ESXi

    I found out (because I had an older ISO), the ISO VMware ESXi 5.5.0-Update2-2068190-HP-5.77.3-Nov2014.iso works well! With this ISO standard, all performance issues disappeared.

    The difference between the ISO is as follows. The former ISO contains the driver of storage scsi-hpvsa 5.5.0 - 88OEM. ISO (s) of March come with new storage driver scsi-hpvsa 5.5.0 - 92OEM or scsi hpvsa - 5.5.0 - 90. These drivers are the cause of the problems in the controller of B120i!

    Installing ESXi 5.5 or 6 since last ISOs, you must manually install the old driver of storage (SCSI hpvsa - 5.5.0 - 88). I tested with the HPSA file scsi vib - 5.5.0 - 88OEM.550.0.0.1331820.x86_64.vib. Then I adjusted the ISO HP and equipped with the old driver. Now I can install ESXi 5.5 or 6 ISO (custom) of HP, which includes the former driver.

    I hope this helps!

  • How can we change the ESXi time for logging?

    Our newspapers to ESXi 4.1 files do not show the exact time. They are about seven hours in the future. We in vCenter configuration of time servers NTP and they show the exact time but Im assuming that the newspaper does not use these time servers?

  • How can we change the TCP/IP ports used by LabView?

    I'm under LabView 8.2 on a computer running windows XP sp2.  This computer is connected to a compact RIO via Ethernet.  The system works very well, but now I am trying to add an IP intercom function (acoustic digital ii3) this intercom uses a program called talkMaster to communicate with the host computer.  I can't communicate with the intercom because this program needs of ports 3000,3002,5000 and 5006.   I used a program called Currports to see what ports are used, and a program called lkcitdl.exe (National Instruments Logos product name) uses port 5000.  Is there a way to change this? I contacted digital sound technical support and they said there is no way to change it at their end.

    Any help would be greatly appreciated!

    Thank you

    Jason

    I believe that we have an article on this somewhere, but I don't have a link at the moment. Under Windows, you can set the port range used by the protocols of Logos in the registry. Reach

    HKLM\Software\National Instruments\Logos\Ports

    You will find two values DWORD here, FirstClientPort, and FirstServerPort, which defaults to 5000 and 6000 respectively. Logos will search for the first available port in the range [FirstClientPort, FirstClientPort + 1000] or [FirstServerPort, FirstServerPort + 1000] when starts a server or a client. By adjusting the registry, you should be able to find a port range that does not conflict with your software. You need to restart all programs OR after you make this change (probably easier to simply restart the computer).

  • How can I change a default install for Flash Player/ActiveX directory

    Hi all

    I try to change a default installation directory:

    The 'Test' folder is created, but completely empty.

    so, I can change a destination for Flash Player folder?

    Thank you

    Hello

    You cannot change the default location for installing Flash Player.  Flash Player installs in a specific directory and browsers know what directory to locate the Flash Player in.

  • How can I change the file association in Windows XP

    All my WORD documents and such are automatically saved in a WORDPAD document, how can I stop that?

    While the file associations in windows do not address how a file should be opened,

    It does not address how a file should be saved.

    the method of saving in a program is controlled by this program.

    Therefore, if you use word 2003, then you must change to save documents rtf to word documents.

    try clicking on Word Tools Menu then Options file.

    then under the tab backup, do not forget to select the right format for saving your documents, IE Word documents (* .docs).

  • Can I change the server port, but Windows Mail continues to change at 25

    I can get my outgoing mail working by changing the port from 25 to 587, but whenever I close the Windows Mail application and re-open it, it comes back to port 25 (and will not work). Thanks for the help!

    You should always back up when you use a Microsoft product.  Your hard drive may die too.  But deleting the e-mail account does not delete messages, and repair the database will not ruin it.  I have not had one person complaining about this program (WMUtil) except for one person who said their antivirus software falsely reported that the file is infected (it was not).
