Agreement between MAX and Windows serial port.

I use a laptop running Windows XP and LabView 8.5.  I have a variety of USB to serial port devices that I use from time to time.  In the past (from what I remember), has accepted the name assigned by Windows, and MAX (COM1, COM2, etc.).  Recently however, MAX seems to think there are three serial ports on the computer, but the tags with a little black 'x' by saying that the device is in a State of 'unknown '.  Using the Windows Control Panel, I see that no serial port is listed in the system until I have Plug one of the converters in.  When the converter is connected Windows automatically recognizes and says it works normally.  It seems that MAX does not allow me to delete the serial ports that scored because they did not add statically.

Is there a way to clear the MAX?  This has not caused any problem I was not able to get around yet, but it should be clarified.

Thank you.

    How can I fix the link between adobe and windows if I see .pdf not win32 application, without the disc?

    "Adobe" is the name of the company that provides a great many different applications.

    Adobe Reader is free and allows you to view pdf files.

    Adobe Acrobat is expensive and allows you to create, edit and view pdf files.

    Assuming that you are referring to the reader, uninstall all the versions of it using the control panel > add or remove programs.  Then either

    1. go to http://get.adobe.com/reader/?promoid=BUIGO and download the current version (remember to uncheck the box to install McAfee Security Scan Plus.

  • Cannot move files between Mac and Windows

    I'm Fusion 8.1.1 and OS X 10.11.5. I can no longer move files back and forth between Mac and Windows (7 x 32 or 7 x 34) while in a single window. In addition, the unit is not available (grayed out). I did a Windows Update for virtual machines two days ago and also a recent update of OS X 10.11.4 to 10.11.5 so I don't know if that's the problem. Everything seems to work another Mac running Fusion 8.0.2 OS x 10.11.5. Do not remember if I've recently updated Windows because the dates are meaningless to me.

    Advice as to why it happens? In the meantime, I'll try to recover a backup of virtual machine before my recent Windows upgrade.

    The fixed! I reinstalled VMware Tools on the W7x32 and W7x64 VMs and found unity and two-way drag and drop. I do not uninstall, just ran Virtual Machine > install VMware Tools in the menu bar. There was no option to reinstall VMware Tools, so I guess that the corrupted Windows VMware Tools update that was there before the update of Windows.

  • MAX sees no serial port of the computer (RS-232)

    Hello

    MAX (measures and Automation Explorer) cannot see the computer s (9-pin RS - 232) serial ports.  I'm using Labview 7.1 and Windows XP (although I think that the manufacturer has also installed Windows Vista).  When I go into control panel > system > hardware > Device Manager > Ports, I see both ports (COM1 and COM2) and both have the latest drivers on them.  Anyone know of any way to add the "Ports" sub-branch under the direction of "Devices and Interfaces" in Max Configuration tree?

    Thanks in advance for your suggestions.

    PS Labview had been stopped in the middle of editing a block diagram, a number of times before and I have reinstalled it a couple of days (without getting rid of the problem, unfortunately).  I wonder if this problem with MAX is somehow linked to the...

    You could try upgrading to 4.5 or simply unistalling/reinstalling the version you have.

  • YouTube videos are green for a few seconds when they start, quickly moving and switch between fullscreen and windowed mode

    suddenly, last night something happened with youtube. whenever I run a video on youtube its green for a few seconds, then it goes back to normal. its also green when I fast forward/jump and when I change between full screen and windowed. I linked to a screenshot of how it looks as if I googled this problem I find something else where people get a green screen but no picture at all and that it lasts the entire video.

    I tried updating the drivers for my graphics card. I tried to play on my nvidia card rather than use my intel graphics hd 4600 and still got the same result, but instead to get a green image, it was really dark almost black. I also tried to reinstall flash even downgrade to an earlier version, but nothing does. and the strange thing is that I only have this problem on youtube and only through firefox so I even tried reinstalling firefox, but that did not work either

    I found 2 things of this kind of help.
    the first solution is to disable hardware acceleration, but instead to get a green image for a few seconds, image frozen for the same period of time and then play and she is like when its Green, when I start it up, jump and change to full or windowed.

    the second solution I found in support for mozilla, to change the HTML5 player. But even if this player works great I really like it. for some reason any the break from the drive when I change between full screen and windowed mode and I don't like these pop-up windows get you that its now in full screen and I can press ESC to quit.

    These are just little things, but I would like to return the standard player.
    If anyone knows anything that could help me with this please let me know.

    This is the screenshot:

    What a little wild speculation?

    YouTube uses a technology that has chopped videos in individual pieces, which is probably video serve more easily, but could create more opportunities for issues when moving in the video. There is an add-on called Center of YouTube that allows you to disable this technology and back to the days of one big file. Might be worth a try.

  • Difference between left and right usb ports 2015 15-inch model.

    I recently bought a 2015 15 inch macbook pro with 2.5 GHz processor and 512 GB hard drive. IV used for only one month and I notice a difference between the left and right usbs. The base of the left usb IE the metal connector pins seem to be lower compared to the usb on the right side. Usb port on the left also seems to be a bit looser than the right, but hardly noticeable. IV barely used the usb ports and would like to know if it's the same for the other macbook pro users with the same model.

    The game is a concern, and I would take the computer to Apple for review. After all, you are covered by the warranty.

    My current MBP is that a 13 inch 2012 has only USB ports on the left side. My previous was a pre-Unibody 15 inches and I have not noticed differences in fit / release between the right and left USB ports.

  • NFC Interaction between BB10 and Windows Phone 8

    Hello

    NFC Peer communication Peer is not the case between BB10 and Nokia Lumia 820 (phone 8 window).

    communications made using the Protocol of the SNEP.

    My request in BB10 able to receive Windows Phone data, but the application in windows phone 8 does not receive the data of BB10 when app in BB10 writing data on it.

    WIndows Phone 8 application works very well (to receive and write data) when I hit with BB 7.1 (curved) Mobile, does not work with BB10.

    app in BB10 works well with all mobile BB, the problem only comes with Windows phone 8. But I could not face this kind of problem with BB7.1.

    Problem is that when I type BB10 with Windows phone 8.

    If a question is existed in app BB10, it should not work with mobile BB

    If a question is existed in Windows Phone 8 App, it won't work with BB 7.1 Mobile also.

    I don't come to the solution where the problem is present.

    Please let me know where is the problem?

    Hello

    I got a more or less immediate response from BlackBerry NFC dev team. There are a number of problems known, all rooted in problems with the device of Lumia. I am told that the NFC open P2P connection Bluetooth transfer on the Lumia is inconsistent with the NFC Forum specification. In addition, there are a problem whereby the Lumia P2P server hangs when used with BlackBerry 10. Once again, our engineers are categorically that the problem is with the Lumia. BlackBerry 10 P2P works very well with devices Android and other Nokia devices.

  • Strategy for sharing media between Mac and Windows Premiere Pro

    I hope that I write in the right forum, it's here or in the hardware forum.

    I'll take the plunge and get a pretty high-end PC to increase my aging Mac Pro for Premiere Pro CS 5.5 (and probably 6 CS as soon as the kinks are developed). Right now my online media resides on several trendy readers fast eSATA RAID 5, on my Mac Pro through some eSATA PCI cards. It works well and I have pretty good bandwidth of 200MBS to 250MBS using this method, I think enough speed for the type of media that I use in my changes, a combination of XDCAM EX, AVCHD, H.264 Canon with maybe 4-5 rivers both in Multicam edits.

    Adding from my PC to the combination will complicate things. I want to be able to access the media on my eSATA drives, which are currently formatted for Mac, using filesystem HFS +. I heard that the Mac drive can make Windows well read this file system.

    The issue is sharing this media on drives fast enough for both systems be able to modify / access simultaneously. I do not have Gigabit ethernet, but I don't think it would be pretty quickly, I think that practically it tops on about 70 MB/second. I probably need more speed.

    Also the Mac can share than the SMB protocol, but does not seem to the current Mac OS 10.7 sharing SMB very well but I test it with Windows. I know for my various boxes of media player, it does not work very well, or at any time to access my Mac 10.7 system via SMB. In addition, SMB seems to be a very slow network protocol. I can share via AFP or NFS, and I think that NFS is the speed you need, do not know if Windows out of the box can cope with this Protocol.

    I know there is such a thing as "fiber channel" and other mainly tech to create a fast network, the Mac can also network via Firewire, but I don't think it will be enough or fast. I guess I could see if it was faster than Gigabit ethernet protocol using Cat 6 or what is the last type of ethernet cable. I am doing a shortcut here and see if the large number of people did and what they think works best.

    Thanks for all the tips here.

    Kind regards

    -Keith

    I guess there are a lot of variables, but change us on a network using the SMB and Gigabit Ethernet and working with fairly similar media (XDCAM HD 422, XDCAM EX, AVCHD or H264) and it works fine. We have two servers sharing between 3 and 4 editing suites. I think that if you are just sharing between two machines, it should be sufficient.

  • Secondary disk between Linux and Windows guests share

    Hi guys,.

    I have a requirement to have a guest Windows and Linux comments share the same disk (formatted in NTFS) and the two systems need full access to the shared file system.

    What I've read, it is possible in some cases, such as the Windows Server cluster.

    Has anyone tried this with Linux and Windows?


    Thank you

    What I've read, it is possible in some cases, such as the Windows Server cluster.

    Windows uses a cluster without sharing, wherever a single node has access on the drive shared at the same time. Microsoft does not support concurrent access to an NTFS file system, with the exception of Hyper-V.

  • It does not sync between iOS and windows laptop.

    I just downloaded firefox for iOS and logged into my account from firefox. I did the same thing on my windows laptop 10 and synchronized together. No story appeared. It says that I have not all devices connected to this account of Firefox to synchronize. What's wrong?

    Hello
    I understand that for the moment that history is no synchronization between a Device IOS and office. I'm happy to help you.

    First of all, what measures do you take to see this "You have not all devices connected to this account of Firefox", second, in the settings on the PC sync, is checked for synchronization history?

    For troubleshooting, first try to restart the synchronization by going to the gear icon and logout at the bottom of the menu. Erase cache cookies private then re-launch of the app and the connection.

  • DataGuard protection mode - difference between max and max performance available

    Hi all

    for maximum performance - transaction can commit both redo entries are written in redolog on the main site. Redo data is written to an asynchronous backup site.


    (T1) the main site to the backup site connection fail, recovery of desynchronization logs will sync on once the connection is established?

    to see availability max - transaction can commit both redo entries are written in redolog on the main site + 1 of the standbysite.  If the main site to the backup site connection fail, it will behave as performance Max once the connection is restored, he will return to the max availability again.

    (Q2) if the main site to the backup site connection fail, recovery of desynchronization logs will sync on once the connection is established?

    Q3) in this case, what is the real difference between mode 2 above?

    Kind regards

    Noob

    Q3 - performance Maximum does not wait do it write in standby when the standby is available; is maximum availability. If the reserves are not available, they are the same.

    Q1/q2 are the same question and the answer is 'yes '.

  • Muse different between Mac and Windows versions

    Me and a friend wanted to test Adobe Muse and we have installed the trial version for 30 days. I did it on my Mac. My friend on his Windows PC. I tried Muse, and when I wanted to show what I have done to my friend, I went to him with the .muse on a USB key file. Us, where he is very surprised that the Muse on the Windows PC could not open the file I did on my Mac due to versioning problems. We compared versions of Muse and... they are different (on Mac: 2014.2.0.569, 787027 CL; Windows: 7.4 V build 30, CL 784238). It is a problem because we wanted to develop as well on the same site, of course not at the same time, but by the way the .muse one to another file.

    Is it normal that versions between platforms is not synchronized?

    Thanks for responding!

    Marc Verschueren.

    Hi Marc,.

    The version of Muse in the machine of windows of your friend is not the latest version, this could be because of the previous installation or windows machine technical specifications are not met.

    Please check the system requirements for windows for output CC 2014:
