Setting up a VISA for a TCP/IP connection

I am trying to write a program in LabVIEW that will allow me to take data from my LeCroy Wavejet 354 and display it in a LabVIEW interface.  I have installed LeCroy's VICP passport.  I have no problems pinging the device so I know my ethernet connection to the computer is good.  It is not clear as to how I can use VISA to establish the desired connection for TCP/IP connections. In MAX, the remote systems function doesn't detect the o-scope's IP address.  I also tried creating a new device under devices and interfaces in MAX and after "create new" it gave me no option to create anything.   Do you have an example VI that can help me see how VISA can be used to establish this connection or know of some other way I could get this to work?  Thanks for the help.
Solved!

Hi BYULab,
Alan from LeCroy Tech Support here...    Unfortunately, the "Accepted Solution" isn't correct.
When using the VICP Passport, you cannot create a TCP/IP resource in MAX for the scope. You can create an alias in MAX via the VISA Options... but it isn't necessary at all.   In fact, you don't need to do *anything* in MAX to connect to the scope.
To connect to the scope, simply enter into the VISA Resource control the following string:  VICP::<ip address> (example: VICP::100.100.100.1)
I've attached a screenshot...

  • I want to set up my router for Peer To Peer connection.

    I recently started playing a new game that requires Peer to Peer connection, and I lag a lot when I log in, so I was wonder what options I would have to check, How to enable/disable options to optimize my gaming connection.
    What kind of router I have is MI424-WR Rev. E Actiontec. Or something along that line.. I was researching what to do and it had a lot to do with DMZ, Ports, and firewall. But any help would be appreciated.
    Im off for tonight so I wont be able to check the post until like 9 hours from now. Goodnight
    Oh if you need to know what game it is for some odd reason its Dungeon Fighters Online, or http://dungeonfighter.nexon.net/
    I like arcade style games.
    Oh and my brother connects to this router to and i want him to keep internet so none of the options can interfear with his internet connection.

    I took a quick look at the www site for the game, but did not see anything definite from the vendor on what port(s) the game uses. 
    You would need to set up you gaming machine with a Static TCP/IP Address and configure the Verizon Router with Port Forwarding of the ports used by the game.  I would ONLY set it up in the DMZ if all else fails.
    Note that the Verizon Router has a small NAT Table which may effect your ability to play a P2P game for extended periods of time.

  • I need help setting Win7 Advanced attributes for the USB drive connected to my EA4500 router

    I can drill down to the Permission Entry for [foldername] window for a folder on the USB drive. There I learn that user group Everyone does not have the Full Control permission box checked. When I check the box and then click Apply, I get an Error Applying Security window. If I click Continue there, I get a Windows Security window that says "Unable to save permission changes on [foldername]. Access is denied." with no way out but an OK button.
    I have Administrative authority in Win7, but maybe I need to know some Unix voodoo to come to terms with my router-mounted drive. I put the drive on the router to make always available, and I'd like to get it to work. For example, I can't turn the archive bit off for any file or folder on that drive when it's mounted on the router. Not with ATTRIB -A and not with XCOPY /M.
    Just to stuff it in my face, XCOPY /M returns a two-line error message for every sub-folder that exists in the target folder:
    Access denied
    Unable to create directory - foldername
    Help! And thanks in advance.

    Bill Dennes,
    (Solutions/Work-Arounds below this paragraph, but sets up some useful information.)
    As for the Security tab, I'm unsure of exactly why it doesn't appear on the tab itself for folders; however, clicking "Advanced -> Change Permissions -> Edit" will display the permissions; although, this doesn't appear to be a part of the problem in a sense. Additionally, “Everyone” always only has read & execute and is also not a part of the issue. To go further with this, the only users that have delete permission are “0” and “root” and since we can delete, we “should” be logged in as one of them and as such have “Full Control.”
    As for the drive type, I'm unsure of why it "changes" it from FAT32 to NTFS (probably something to do with how it handles permissions); however, this is also not a part of the issue.
    I have a flash drive formatted to FAT32, albeit only a 4GB and on an EA6500 with secure sharing enabled, that it does these both to and "xcopy testfolder Y:\ /e /m" works on it when all files and folders have the A attribute; however, disabling secure sharing makes it fail.
    I’ve looked further into this and there are three ways I know of, as of right now, to make copying files with the bat file work for you:
    The first way is to enable secure sharing and map the drives using it, once that is done you won’t need to enter the password again and your script will work as you currently have it coded. Given you have no need for the secure sharing, but it’s a simple solution. This is also the only way to be able to modify any attributes, although the only ones I know of that it will accept are R and A.
    The second way is to instead use ROBOCOPY with the options /e, /m, and /copy:dt.
    For example: "robocopy testfolder Y:\ /e /m /copy:dt"
    /e = Copy subdirectories, including empty ones. (or use /S which will not copy empty folders)
    /m = Copy only files with the Archive attribute and reset it.
    /copy:dt = Copy data and timestamps, does not copy attributes, security, owner info, or auditing info.
    The only important option to use is /copy:dt, the others can be replaced with whatever you need. Note that things like Song Author will still get copied as they are a part of the data section. I don’t believe XCOPY supports doing this, and in either case robocopy is a better solution that comes with Windows Vista and up, and can be gotten for those below Vista.
    The third way is to add a section to the script to remove attributes from all folders before using xcopy to copy to the NAS, or modify the section that is causing the folders to have the A attribute as xcopy will gladly still copy them with /E or /S enabled.
    The issue seems to be that when secure sharing is off, the server refuses attribute changing of folders, which is what is causing XCOPY to fail, as I suspect it attempts to change the attributes on the folders. Similarly, using robocopy without /copy:dt will also fail but gives you “Error 5 … changing file attributes [folder/path] Access is denied”. This is why I suspect that when XCOPY says “unable to create directory” that it is actually trying to change the attributes of the directory. Furthermore, it seems that the reason this works while secure sharing is on is that while it is on, the server pretends to accept the attributes but in reality ignores all attributes besides R. The server then adds the A attribute to all files put onto it, which you can only modify when secure sharing is enabled for some reason. The exception to this is that in either case, any file with the “H” (hidden) attribute, will not be copied, even if explicitly told to copy it. (This is true for both robocopy and xcopy; you also cannot manually add it afterwards.)
    Is there an issue with the files on the NAS having the A attribute? If so the only way I currently know of to get rid of it is to enable secure sharing and have the script remove the attribute after copying. For example, when you look at the permissions, the user "0" and “root” have full control as I've previously stated. You can tell Windows to specifically use one of them when mapping the drive, which in turn should give you full control; however, the server still refuses modifying attributes without secure sharing on for some strange unknown reason. Although, I am no "UNIX gearhead," so there may in fact be another way that I do not know of. The only time they are not listed as “Full Control” on my end is when a file was previously marked Read-Only, in which case they all share the same limited control. When I said in the beginning that the permissions are not a part of the problem in a sense, it’s more of that for the general case of what you need to do, they aren’t the problem as long as you don't need the R attribute and having the A isn't an issue, as it seems to be more of the server is refusing attributes even though we should have permission; however, they do appear to be a bit weird and are possibly displaying incorrect when secure sharing is disabled.
    I'd like to apologize in advance for any unclear, weirdly stated, or just plain odd things said in this post as I was pulled away to do a bunch of things and ended up editing, adding things, and finishing it late into the night and hope that one of the above is an acceptable resolution to your issue.

  • Prevent TCP IP connection to be interupted

    Hi!
    What would be the best way to ensure that TCP IP connection remains open (continious read from device) and uninterrupted.
    I have two software that connect to device via TCP/IP. I developed one software in Labview and reading from device is successful. The problem is that if I connect with other software while I am connected through Labview the connection on Labview breaks and I get an error. 
    Is there a way to ensure uninterrupted TCP/IP connection in Labview?

    Technically a TCP/IP connection is defined by the four specific information points IP address and port number on both ends. At least one of them needs to be different for a TCP/IP connection to exist more than once between two endpoints. So assuming you open a connection from the client side using autmatic port assignement (the default since a client usually doesn't care on which port the local side of its connection is bound), this should work.
    However that is the specific capability of the TCP/IP socket library routing capability. A client and/or server or a specific protocol can impose additional limitations on this. As it is described here, the server application seems to accept new connections even if it is already serving another one but then drops the first connection forcefully. That is unusual but definitely possible to implement in a server, possibly intentional but just as possible a bug in the server application.
    That is if you don't (have to) specifiy a local port on the client side. If you do then yes the new connection started on the same machine will have all four information elements to be the same for both connections and whoever comes last in establishing such a connection will snatch it away from anyone else. In that case this is an inherent property of the TCP/IP spec and there is no possibility to avoid this, safe from using different local port numbers on the client side (if the server allows that!) It's possible to imagine a server application that only allows connections from a specific port (range) although that would be a pretty unusual TCP/IP protocol specification.

  • Does anyone have a set of .VIs for talking to a generic modem?

    Hi and thanks for reading.
    I don't want to have to know AT commands, just what I want to do. Such as go off hook, dial a number, wait for answer etc.

    Stan,
    Maybe the attached VI will help. This VI library contains utilities to talk via the serial port to a modem. Sending standard Hayes-compatible AT commands to the modem allow it to dial a number, send data, hang up, etc.
    If you have the Internet Toolkit, it assumes you already have a valid TCP/IP connection. However, many web browsers such as Netscape and Internet Explorer have auto-dialing options that will start dial-up networking automatically when you launch your browser. The only trouble is that the auto-dial wizards can require the user to push buttons, but there is a Shareware program called DUNCE which will take care of the button pushes for you in the auto-dial wizards so the user does not have to intervene in the dial-up process.
    You can la
    unch the browser from LV and then have the browser configured for auto-dial and that should take care of the problem. I did not actually try this out myself, but in theory, it should work.

  • HT4576 I want to set up appointment times for an overseas trip before I go, and see those local times in the places I visit, but also be able to set new appointments while I am traveling, in the local times.  Can I do this with Time Zone Support?  If not,

    I want to set up appointment times for an overseas trip on my iPhone 4S before I go, and have them appear as I put them in (for the local time) when visiting other countries.  I also want to be able to adjust times and set up new appointments when I am overseas for the local time.  Can I do this using the Time Zone Support or any other way? 
    Basically I want to do what I can do with a piece of paper - write down the time for when I will be there, and have it viewable when I am there, but also be able to put down new times while there.

    Hi.
    Regarding your question about reverting back- yes, I think you can. If you make a backup of your current configuration in Server Admin (by dragging the configuration file to your desktop- cool, no?) then you can load that one back in should your configuration not work. If you have the manual from Apple it should describe this process.
    Network speed post-op? I don't think you will need to worry. Even using home directories stored on our OS X Server there is no network slowdown (that you can notice or that impacts the wider LAN in any case). It shouldn't slow down access to files, applications (which still come from the local drive anyway) or individual internet connections (even with filtering).
    In our experience some of these things have actually got faster- but a lot of that is user perception. Same goes for people who will know you have configured the server and that they are now accessing files through your network from the server, and who really think it is slower. File coming from your local hard drive will always be quicker- but network access isn't that bad that it will make you barf and run in the opposite direction.
    Something to look at: connection speed between clients and switching technology in your office. In other words, what kinds of switches are you using, what line speed have you got (100MB/s?) and is the connection from your server to the switch gigabit? Make sure it is.

  • The TCP/IP connection does not closed after a VISA close

    I am using the VISA functions to communicate with a Sorenson SGA power supply from a Windows XP computer.  I have the VISA TCPIP Resource defined in MAX and use this alias name in the VISAResourceName for the input to the VISA Open.  Then I write a SCPI command, such as *IDN?, and read the repsonse.  Then I close the VISA session.  When I look at the TCP statistics using the netstat -n command, I get the following response:
    Proto           Local Address                 Foreign Address    State
    TCP            10.10.10.9:3881              10.10.10.1:111       TIME_WAIT
    TCP            10.10.10.9:3882              10.10.10.1:111       TIME_WAIT
    If I query the ID again, I get 2 more TCP connections with different local ports numbers.  Every time I perform the query, I get 2 more TCP port connections at different local ports.  It takes about 1 minute for the TIME_WAIT's to time out.  If I query the Sorenson enough, I can fill up my allowable local port connections.
    1)  Why doesn't the TCP connections go away after the VISA Close?
    2) Should I be opening and closing the VISA session every time I want to talk to the Sorenson?
    3) What does the VISAResourceName control or constant actual do to resolve the alias into a IP?
    This Sorenson power supply does not seem to be very quick to repsond to TCP requests.  If I set the timeout on the VISA Open to anything less the 100ms, I cannot get a session open every time.  It will fail about 50% of the time.
    Has anyone had experince talking to the Sorenson power Supplies using VISA TCPIP?
    Thanks,
    Julia

    Hi Julia,
    Let me try answering your questions here.
    1) I'm actually currently looking into this to see if this is expected behavior, and I'll definitely post back to let you know what I find.
    2) You do not need to close a VISA session everytime you want to communicate with the device, you can leave the same session open and keep using that session, instead closing it out at the end.
    3) The VISA aliases and what they correspond to are stored in a visaconf.ini file. There is more information about this file and where it is located on your hard disk in this KnowledgeBase article here. This visaconf.ini file is checked to see what the actual resources being looked up are.
    Let me know if I answered your questions, I will write back with more information on question 1.

  • Establish a connection through RF modem's on client & server side & to set up PPP communication for data transfer

    hi
    can any1 over here help me out in how to establish connection between 2 RF modem's for data transfer , between client & server USing LABVIEW?
    I want to establish a connection between 2 PC's through  RF modem on client & server side & to set up PPP communication for data transfer.
    (I have tried data transfer through RS-232 using TCP/IP whn the 2 PC's are connected over ethernet... which is working.
    I also tried connecting loopback cable between 2 PC's COM port & geting data transfer using VIsa configure serial port & other visa functions  ... which is working)
    can u guide me how to establish connection between 2 RF modem's using LABview?
    & how does the data transfer take place between 2 RF modems through RS-232?
    is it using TCP/IP?
    If you got any links to go abt this issue do send me related links .. or any examples .....
    I am currently using Labview version 8.
    Waiting in anticipation.. reply ASAP..
    thanking you
    Regards
    Yogan..

    Howdy yogan,
    Maybe you could clarify a few things for me, and we'll see how we can help ya. TCP/IP protocol occurs through an ethernet connection; RS-232 communication occurs through an RS-232 serial connection, typically through a cable that has a DB9 connector on both ends. Do you mean that the RF modems in question have the option to communicate via RS-232 and/or via TCP/IP ethernet? Specific information like the manufacturer of your RF modems, the model number of your RF modems, and how you connect the modems to the PC would enable us to give you more efficient support.
    You can check our Instrument Driver Network (IDNet) to see if a plug-and-play/IVI driver already exists for your RF modem. (You'll need to know its manufacturer and model number.) In the case that you do find an IDNet driver for your modem, you can use this KnowledgeBase article for instructions on how to use the driver.
    Another excellent resource to consider is the NI Example Finder. You can access this within LabVIEW by navigating to Help»Find Examples and then searching for serial or TCP/IP examples.

  • How do I use the VIs for the Fluke Hydra Series 2620a multimeter?

    This message refers to the VIs found at this link:
    http://sine.ni.com/apps/we/niid_web_display.download_page?p_id_guid=E3B19B3E9468659CE034080020E74861
    How do I use the VIs for the Fluke Hydra Series 2620a multimeter? I am conducting a Senior Design Project at Temple University. It is a Control System where I need to read voltages from sensors and output voltages to different system components. I am trying to set up a VI using the VIs found above to make sure that I can successfully read and send voltages. There was no documentation given with the 2620a VIs.

    Unfortunately, you've got a very old driver for an old instrument. The only available help is to turn on Context Help and move your mouse over the VI icon. It doesn't appear to have any help for individual controls and indicators. The only good news is that it appears to be a simple instrument with only a few functions. There's some main ones line initialize (to set serial port), configure channel, configure instr, and read values. One main thing is whether you're using gpib or serial, Each front panel has a setting. If it's gpib, set the port to the gpib address. If it's serial, set the port to one number less than the com port you're connected to. For example, if you're using Com1, set the port to 0. For the other controls, I'm afraid that you're going to have to try and compare what's there with the controls and settings of the actual instrument. Having access to the instrument manual will be essential. I would engourage you to experiment a little. There's probably very little chance of damaging the instrument especially if nothing is hooked up to it. Send a command and see what happens or set the instrument up manually and see if you can reproduce that via remote control.

  • How do you set up Port Forwarding for ARD 2.2 in AEB N?

    Help,
    I'm a novice at Apple Remote Desktop (ARD) - not an IT guy, so it has to be pretty basic and detailed.
    How do you set up Port Forwarding for ARD 2.2 on the Apple Airport Extreme BS router, 802.11 N. I have one at each end of the internet connection. At one end I have an Airport Extreme N router with 2 macs and eventually 1 windows XP machine (if I can) that I would like to be able to connect to over the interenet (the clients) and at the other end, I have a Mac with ARD 2.2 installed also with an Airport Extreme N router. Note: Both routers use Static IP addresses and all computers use static IP's internally not through DHCP. What are the settings or directions to do this.
    I have read and printed out the directions for Configuration of ARD 3.0 that are posted many times in the ARD discusion group, but it uses a Linksys router ( http://www.starkpr.com/ard.htm posted by Dave Sawyer). The Mac router is different, particularly with the place to set a Private IP address. I'm not sure about alot of things, but especially about the Private IP address, what number do I set it to, the one that is in my Network connections list? It automatically changes to a different number in AE N setup for Port Forwarding (by one) as if it is not suppose to the same?????
    Are there any directions available that are as straight forward for the Airport Extreme N router, as the one's that are listed here for the Linksys Router's? ( http://www.starkpr.com/ard.htm )
    Any and All help will be greatly appreciated.
    P.S. I know I should have 3.0 but bought 2.2 just weeks before 3.0 came out and they would not give me an upgrade price, so I'm waiting for 4.0 to upgrade.
    Thanks,
    Jim

  • How do you configure the set of port to use for FTP passive data connection

    I was able to start the ftp server xml db and connect to it locally. When I tried to connect to it from home, I was able to log in but when i do a "get" command the sessions hangs. I also tried passive mode and do a "get" command and it gives me a connection refused error. I am using the default port 2100. I think this might be a firewall issue with the data connection port. I am not sure which range of ports to open for the passive ftp connection on the server side or where to go and set them for for the ftp server to use? Or this issue might not be firewall related??? Any thoughts. Thanks.

    This is a typical problem with VPN/Firewall software and FTP on ports other than 21.
    When you open the FTP data connection the FTP Server identifies which port the data will be sent on using the PORT command which is sent on the command port (typically 21 with a normal FTP server, 2100 by default with XDB). THe client then opens that PORT to accept the data (file, output of an ls etc).
    As I understand it most VPN/Firewall are configured to monitor 21 for 'PORT' requests. They then understand to allow connection on the PORT number passed on the command PORT. Hence with Port 21 firewall / VPN software is not a problem. However since the XDB command PORT is something other than 21 they do not see / honour the PORT commands from the server and hence the client cannot open the data connection on the specified PORT
    As to how to solve it, I wish I knew (After 5 years I still can't use XDB FTP from home to a machine in the office once the VPN tunnel is open :( ). I'm sure it's going to be firewall / VPN software specific and may need the VPN servers to be configured.
    The best bet would be to run the FTP server on 21...
    Add the following line to your listener.ora file
    (DESCRIPTION =
    (ADDRESS = (PROTOCOL = TCP) (HOST = hostname) (PORT = 21))
    (PROTOCOL_STACK = (PRESENTATION = FTP) (SESSION = RAW)))
    and then restart the listener as root
    Start the listener as root.
    At the operating system prompt, enter tnslsnr with optional command line arguments. The usage is as follows:
    tnslsnr [listener_name] [-user user] [-group group]
    where:
    Table 4-3 tnslsnr Utility Options
    Option Description
    listener_name
    Specify the name of the listener. If omitted, the default name LISTENER will be used.
    -user user
    Specify the user whose privileges the listener will use when super user (root) privileges are not needed. After performing the privileged operations, the listener will give up root privileges irreversibly.
    -group group
    Specify the group whose privileges the listener will use when super user (root) group privileges are not needed. After performing the privileged operations, the listener will give up root group privileges irreversibly.
    The listener will temporarily switch to the provided user and group immediately after startup. All subsequent operations will be done with the specified user and group privileges, except the system calls necessary to listen on configured endpoints. The listener will revert to super user (root) for a short period of time to listen on reserved addresses, such as TCP ports less than 1024. After the listener starts listening on all of its endpoints configured in listener.ora, it will switch to the specified user and group irreversibly. Therefore, the listener will give up the root privilege that it initially had. In the current release, -user and -group command line arguments only accept user and group identifiers specified in numeric form.
    For example, to execute a root listener called mylsnr and have it use privileges of a user identified

    ■ Easiest method, if you allow firefox to tabs you used then on restarting I believe it also retains the zoom settings
    * '''Tools -> Options -> General -> Startup = use current pages'''
    ■ There are also extensions that can be used, some allow individual sites to have individual settings. Look at the [http://support.mozilla.com/en-US/questions/772884 this thread] which also discusses related matters.
    ■ The best method if you need the same effest accross all sites is probably changing one of the preferences within the config files, it is discussed in the above linked thread and also in this MozzillaZine article http://kb.mozillazine.org/Layout.css.dpi

  • Example VIs for winsock with LabVIEW 7.0

    Are there any example VIs for TCP communications with winsock using LabVIEW 7.0?

    I would like to join the request - I would like to know how to use WinSock from within LabVIEW to use a modem to dial a number and connect to another PC with a modem. An extra complicaiton is the fact that I need to be able to vary the number (to access numerous data acquisition stations).
