Visa test panel works, but visa write that VI does not work

Hello everyone, this is my first post here

I'm trying to communicate with an instrument of piezo controller using my serial port.  I can successfully write a command using the Panel to test visa, "AV20\r" for example sets all channels of voltage of 20 volts.  In my labview vi, I set up the serial port with the same settings as I see in the Panel to test and run it, but the device does not respond.

Any suggestion would be greatly appreciated, I'm sure I must be missing something simple here...

Thank you

Brian

Are you sure your string constant or control in LabVIEW that contains the string is configured to show the \codes attributes?

  • Clip don't disconnect but Windows says that it does not recognize it?

    I loaded my Clip - when I pick up the computer, it shows that its connected and it will not power off - the screen which shows just its connected to the computer and fully charged, also when I plug it into the computer, I get a message that says: "one of the USB devices attached to this computer has malfunctioned and Windows does not recognize it." and told me to try to reconnect the device.  I've updated the firmware.  I just bought this in September-Help!

    With the Sansa unplugged, press and hold power button for 20 seconds, then exit (Clip +), or slide the switch to the position and take it 20 seconds (Clip).

    Then try to turn on normally.

    will update the driver stack.

    Now, go to the system manufacturer's website and download the latest driver for the camera and the other related camera

    You may have installed one or more variants of the malware "VSearch' ad-injection. Please back up all data, and then take the steps below to disable it.

    Do not use any type of product, "anti-virus" or "anti-malware" on a Mac. It is never necessary for her, and relying on it for protection makes you more vulnerable to attacks, not less.

    Malware is constantly evolving to work around defenses against it. This procedure works now, I know. It will not work in the future. Anyone finding this comment a couple of days or more after it was published should look for a more recent discussion, or start a new one.

    Step 1

    VSearch malware tries to hide by varying names of the files it installs. It regenerates itself also if you try to remove it when it is run. To remove it, you must first start in safe mode temporarily disable the malware.

    Note: If FileVault is enabled in OS X 10.9 or an earlier version, or if a firmware password is defined, or if the boot volume is a software RAID, you can not do this. Ask for other instructions.

    Step 2

    When running in safe mode, load the web page and then triple - click on the line below to select. Copy the text to the Clipboard by pressing Control-C key combination:

    /Library/LaunchDaemons

    In the Finder, select

    Go ▹ go to the folder...

    from the menu bar and paste it into the box that opens by pressing command + V. You won't see what you pasted a newline being included. Press return.

    A folder named "LaunchDaemons" can open. If this is the case, press the combination of keys command-2 to select the display of the list, if it is not already selected.

    There should be a column in the update Finder window. Click this title two times to sort the content by date with the most recent at the top. Please don't skip this step. Files that belong to an instance of VSearch will have the same date of change for a few minutes, then they will be grouped together when you sort the folder this way, which makes them easy to identify.

    Step 3

    In the LaunchDaemons folder, there may be one or more files with the name of this form:

    com Apple.something.plist

    When something is a random string, without the letters, different in each case.

    Note that the name consists of four words separated by dots. Typical examples are:

    com Apple.builins.plist

    com Apple.cereng.plist

    com Apple.nysgar.plist

    There may be one or more items with a name of the form:

    com.something.plist

    Yet once something is a random string, without meaning - not necessarily the same as that which appears in one of the other file names.

    These names consist of three words separated by dots. Typical examples are:

    com.semifasciaUpd.plist

    com.ubuiling.plist

    Sometimes there are items (usually not more than one) with the name of this form:

    com.something .net - preferences.plist

    This name consists of four words (the third hyphen) separated by periods. Typical example:

    com.jangly .net - preferences.plist

    Drag all items in the basket. You may be prompted for administrator login password.

    Restart the computer and empty the trash.

    Examples of legitimate files located in the same folder:

    com.apple.FinalCutServer.fcsvr_ldsd.plist

    com Apple.Installer.osmessagetracing.plist

    com Apple.Qmaster.qmasterd.plist

    com Apple.aelwriter.plist

    com Apple.SERVERD.plist

    com Tether.plist

    The first three are clearly not VSearch files because the names do not match the above models. The last three are not easy to distinguish by the name alone, but the modification date will be earlier than the date at which VSearch has been installed, perhaps several years. None of these files will be present in most installations of Mac OS X.

    Do not delete the folder 'LaunchDaemons' or anything else inside, unless you know you have another type of unwanted software and more VSearch. The file is a normal part of Mac OS X. The "demon" refers to a program that starts automatically. This is not inherently bad, but the mechanism is sometimes exploited by hackers for malicious software.

    If you are not sure whether a file is part of the malware, order the contents of the folder by date modified I wrote in step 2, no name. Malicious files will be grouped together. There could be more than one such group, if you attacked more than once. A file dated far in the past is not part of the malware. A folder in date dated Middle an obviously malicious cluster is almost certainly too malicious.

    If the files come back after you remove the, they are replaced by others with similar names, then either you didn't start in safe mode or you do not have all the. Return to step 1 and try again.

    Step 4

    Reset the home page in each of your browsers, if it has been modified. In Safari, first load the desired home page, then select

    ▹ Safari preferences... ▹ General

    and click on

    Set on the current Page

    If you use Firefox or Chrome web browser, remove the extensions or add-ons that you don't know that you need. When in doubt, remove all of them.

    The malware is now permanently inactivated, as long as you reinstall it never. A few small files will be left behind, but they have no effect, and trying to find all them is more trouble that it's worth.

    Step 5

    The malware lets the web proxy discovery in the network settings. If you know that the setting was already enabled for a reason, skip this step. Otherwise, you should undo the change.

    Open the network pane in system preferences. If there is a padlock icon in the lower left corner of the window, click it and authenticate to unlock the settings. Click the Advanced button, and then select Proxies in the sheet that drops down. Uncheck that Auto Discovery Proxy if it is checked. Click OK, and then apply.

    Step 6

    This step is optional. Open the users and groups in the system preferences and click on the lock icon to unlock the settings. In the list of users, there may be some with random names that have been added by the malware. You can remove these users. If you are not sure whether a user is legitimate, do not delete it.

  • I said that I have to install Chrome to place an order at Walmart. What should the Chrome that Firefox does not work?

    I have placed several orders of Wal-Mart before today using Firefox without any problems. But today, nothing but problems. I tried for more than 4 hours, get this order to cross. I told cat line of Walmart and told me that I have to install Chrome to place an order. They don't answer when I asked if Walmart belonging to Chrome.

    I deleted the cookies and cache and restarted but none of this has worked. While Chrome has that Firefox does not work? I tried Chrome before and he hated and had a devil of a time he get off my computer. I don't want to go there again.

    I have attached a copy of the message that I get seems to indicate that it is a problem within Wal-Mart, but I said that it was with my browser.

    I have a laptop Toshiba Satellite running Windows 7 Ultimate 64 bit and using Firefox 40.0.3.

    Any suggestions would be greatly appreciated. Thank you.

    Thanks for your reply. I just figured out the problem.

    All started when I tried to pay my order at 13:00 this afternoon. I am persistent and don't give up easily. Five hours later, I found an error in their programming, which allowed me to add an item to my shopping cart that was a purchase in store only. But then when I went to pay for it, he became confused and wouldn't let me order but didn't tell me why.

    I solved by moving all items in the basket to saved for later and then add one at a time, trying to get to the car after each addition. It took a while because there are 20 items. He had the same problem when I added the item in the store to the cart and tried to pay for it. So I deleted and purchased on Ebay.

    Now I know probably as much if not more than any of their populations of the Chat line that can only be read on a book script.

    It's a relief that I don't have to use Chrome. I really like Firefox and would not change.
