  • LeCroy LT344L, MAX, IVI and the Ethernet connection

    Howdy!

    I installed lcltxxxx IVI driver of the NOR for the scope of LeCroy LT344L.

    IVI Compliance Package: 4.5

    MAX 5.4.0f0

    I want to use an ethernet connection, but the area of selection "Descriptor resources" does not offer a resource ethernet (see photo).

    With the help of the software ScopeExplorer of LeCroy confirms a working communication between the PC and the scope.

    I do not use the two program (MAX + ScopeExplorer) at the same time.

    Thanks for the help!

    Oh...

    In addition, the 'LeCroy ACIP passport' is necessary for communication via TCP/IP: http://teledynelecroy.com/support/softwaredownload/vicppassport.aspx

    As "Resource Descriptor' the text 'VICP::172.30.2.26' (IP of my scope) works for me.

    I compressed upwards and tied the ethernet driver that shows support for the hardware ID you have validated, below.

    You will need to manually install the driver as follows...

    Download and uncompress the file that I attached to his record.  Do nothing with the files in the folder.

    Go to Device Manager and click on the ethernet controller requiring driver.

    Click on the driver tab, click on set to update driver.

    Select her browse my computer for driver software option and navigate to the folder you unzipped.

    Make sure that the include subfolders is selected, and I hope that the driver will be installed.

    Then restart the PC and see if you have network connectivity.

    Can someone help me how to solve this problem.

    Kind regards

    If it is an Oracle database, you connect to so be, you must enable the custom URL and change the url to server connection: port: sid to the server: port / servicename

    Also you can get better Planning_WebApp.log that is located in the directory the plannning managed server logs the log information.

    See you soon

  • Do I need a PCI Ethernet card on my Mac mini to connect to the Ethernet connection?

    I tried to set up my mac mini on my ethernet newly updated. Nothing seems to work. When I scanned the information system and click on the Ethernet cards, I received the message: this computer does not have any Ethernet PCI cards installed.

    He may be waiting the connection end. Network connection attempts take awhile to timeout - the order of minutes. If you are debugging in the Simulator, you shot above the MDS Simulator? If a device is connected?

    You can also take a look at the CoverageInfo class as a way to check the availability of connection before you actually start a connection.

  • What's happening: exception 'RTCError' with the message "connection failed"?

    Hello

    I focused the second time this week that there are problems with the connection to the servers of low-COST airlines. Last problem was at about 10:30 CEST. It takes at least 15-20 minutes - I know not how long this problem has really, because I know about this than if my customers report a problem. For the same reason, I don't know if this has not happened more often, because I'm not check every 5 minutes.

    When this problem occurs, I have exception:

    'RTCError' of exception with the message, "Cannot connect" in /var/www/lib/LCCS/lccs.php:774

    Stack trace:

    No idea what is worng? Some work on the Adobe servers?

    I hope it will be useful for people with similar problems.

    We sought with Jamie Ho where is the problem, but it is impossible to detect the reason. Traceroute test shows nothing interesting. Newspapers to also analyze.

    The solution we found another server (hosting in other place / data center) uses as a portal to communicate with supply services. It has helped, and that door connects no problem now.

    But what is strange, we tested more servers and it is a lottery. One of our test servers could not make any connection with procurement services. I found here http://forums.adobe.com/thread/772442 that this is not a new situation.

    This is what it looks like now. We monitor it all the time, but for now this Portal Server solution seems good and he is the only one that solve problems.

  • Have the intermittent connection when you use WiFi and conflict error IP address when using Ethernet

    I have intermittent problems with my wireless internet connection. I contacted the ISP and they analyzed the configuration of the modem-router, changed some and told me to try to reconnect. I try again and the connection is OK. The ISP has caress each other on the back and sent me on my merry way not-so-small. Problem is at an unpredictable time, problems (do) happen.

    Usually the failure scenario does not have a huge problem - plus one
    gene as a problem. I just keep trying to connect through Windows
    Network and sharing Center, and possibly the connection is made. But in some cases, time is critical; I eventually lose 10 to 20 minutes of typing-search-typing-correction-etc in a web form when the connection disappears before making a SHIPMENT. (Some time, after the failed wireless and re - connect, I was actually able to recover pretty quickly that the site has not been exceeded me.) So in this scenario I can't lost any strike.)

    I would like to connect my pc to the internet via an ethernet cable
    the modem-router. I could take this approach right after the wireless
    connection failed. Or in a preventive way, when I know I'll be typing-
    mode of research-type-fixed-etc and I want to be really sure. When I tried this, I get the error "Windows has detected an IP address conflict.

    What I do at this point to get around the Wi - Fi connection and connect through the Ethernet cable?

    [Original title: LOST INTERMITTENT WIRELESS INTERNET CONNECTION]

    It is not clear what parameters your ISP technology management may have changed on your modem/router.  As a general rule, the ISP concerned the link between their server and your modem, but any fiddling with settings that control this link will not effect either on the link between your computer and the modem/router.

    If you still haven't reset your router to its default settings, do not unless you know the necessary internal router settings for you connect to your ISP.  If you have a cable Internet connection, the default settings may work OK, but if you have a DSL, they probably won't.

    You should not get this "IP address conflict" error when you connect the Ethernet cable.  Follow these steps:

    Open the "network and sharing Center" and then click on "change adapter settings".  You should see an icon for your wireless network adapter and an icon for your 'connection to the Local network' (your Ethernet connection).

    • Right click on each of the icons, and select 'properties '.
    • There should be a list titled "this connection uses the following items."  In this list, select "Internet Protocol Version 4 (TCP/IP)" and then click "Properties".
    • The radio buttons to "Obtain an IP address automatically" and "Obtain DNS server address automatically" should both selected.  If this is NOT the case, do so and OK your way out.  Furthermore, cancel your way.

    If a card has been configured to use a specific IP address, your "IP address conflict" should now be fixed (you may need to restart the computer for the change to take effect).

    If cards were already configured to obtain its IP address automatically, the problem lies in the configuration of your router.  You will need to access the router's Web utility to study and make changes.  To help you provide the brand and model of the router of the label on the back or the bottom.  Also do the following to a time where you have an Internet connection:

    Open a command prompt window (type cmd in the search box and press enter)

    1. In the black command prompt window, type the following command, and press ENTER after each line

    ipconfig/all > "% userprofile%\Desktop\ipinfo.txt".

    Notepad '% userprofile%\Desktop\ipinfo.txt '.

    output

    1. In the opened Notepad window, click Edit > select all (or press CTRL + A) and then click Edit > copy (or press Ctrl + C)
    2. In the body of your Question, right-click > paste (or press CTRL + V) the data of the Notepad window
    3. Close Notepad and remove ipinfo.txt from your desktop

    Help, please!

    The secure connection failed

    I think it's a problem with the validation, verification and update of better weather its works or not!
    Thank you.
