Connection to the meter via LAN without VISA library

I connect my HP33410A via a LAN cable to my PC using the VISA library. I'll send SCPI commands and everything works OK.

But my application must also connect without a VISA and for me it's a big problem. I read some information, I have to use the SOCKET connection with the TCP feature.

Is there a simple way to do this? I was punctuating certain functions in LabWindows supporting TCP protocols and socket. SDK library also support the SOCKET connection, but for me it's black magic

Could someone post here a code to query a simple as command "* IDN?" in this interface LAN without a VISA?

I would be grateful

(Sorry for my English I hope you could understand the problem, I describe )

I solved the problem. It is more simple than I thought you just have to connect to the TCP server. Earlier, I tried to do that, but with the incorrect port number. I think that for most of the devices Agilent TCP port number is 5025 (I've read that in manual for SOCKET connection)

I stayed here a piece of code that shows how to establish a connection with the agilent device:

ConnectToTCPServer (& tcpHandle, 5025, '169.254.4.10', TCP_Handlig_Function, 0, 0);
ClientTCPWrite (tcpHandle, "* IDN?", 5, 0);

ClientTCPRead (tcpHandle, buff, 50, 0);

And that's all you need to do. Is not as simple as that?

  • Re: Satellite Pro L670-103 - not able to connect to the internet using LAN

    Hello

    I am unable to get my L670-103, in the case of Windows 7 Pro (x 64), to connect to the internet via the ethernet jack.

    I tried running the troubleshooter in windows and reinstall the driver ethernet with no luck.
    The computer used to work fine with the same network (I have no control on the network itself, as I'm on a University campus), and my other, much more old laptop (with XP), connects with no bother.

    I'm sure the question is focused on software that - I tried to go online on the same socket after booting from an Ubuntu live CD, and it worked fine.

  • Win 7 cannot find the driver on the laptop to HP Deskjet 5600 connected to the office via WLAN

    I have HP Deskjet 5650 color printer connected to desktop Dell Dimension 2400 under Windows XP Home Edition Ver 2002 SP3. I just bought a laptop Dell Inspiron N4110 running Windows 7 Home Premium SP1 64 bit.

    I am trying to connect to the printer via my home WIFI network running through a Netgear Wireless-N 150 WNR1000 router.

    When I add a printer on the laptop, it shows on the list of printers available on the select a printer screen, but when he tries to connect, it returns with a message, "cannot find a driver for HP Deskjet 5600 series on the network.

    I tried to locate the driver manually, but without success. I have an older HP laptop that is running Windows XP, which has always connected to the printer via the WIFI network very well.

    Can I connect the printer directly to the new laptop via a USB port and it recognizes, installs and runs very well.

    But I need accessible and connected permanently to the desktop from the laptop when it is connected to the WLAN.

    Can someone tell me how I can get my new laptop to locate driver files on when connecting via the WIFI network, please?

    Thanks for your help!

    Very well!!  He finally got!

    had to go to the properties of the computor, advanced system properties, system, device installation settings and game to install drivers from windows update if it is not found on my computer.

    Then, it would finally be search on windows update for drivers, but would not yet find a driver even from windows update to the printer when installing it as a network printer.

    I had to add a printer as a local printer, and then select Create a new port, local port, and the port name, I had to enter the path through the network computer to the printer (as "\\desktopname\printername").

    Then and only then, did that pick me from a list of printers, and we found a driver on windows update.

    Yet once again, I appreciate your help! Looks like we may have learned something from this experience.

  • Connected to the ASA via the "VPN Client" software, but cannot ping devices.

    I have a network that looks like this:

    I successfully connected inside the ASA via a software "Client VPN" tunnel network and got an IP address of 10.45.99.100/16.

    I am trying to ping the 10.45.99.100 outside 10.45.7.2, but the ping fails (request timed out).

    On the SAA, including the "logging console notifications" value, I notice the following message is displayed:

    "% 305013-5-ASA: rules asymmetrical NAT matched for flows forward and backward; "Connection for icmp src, dst outside: 10.45.99.100 inside: 10.45.7.2 (type 8, code 0) rejected due to the failure of reverse path of NAT.

    I have a vague feeling that I'm missing a NAT rule of course, but not all. What did I miss?

    Here is my configuration of ASA: http://pastebin.com/raw.php?i=ad6p1Zac

    Hello

    You seem to have a configured ACL NAT0 but is not actually in use with a command "nat"

    You would probably need

    NAT (inside) 0-list of access inside_nat0_outside

    He must manage the NAT0

    Personally, I would avoid using large subnets/networks. You probably won't ever have host behind ASA who would fill / 16 subnet mask.

    I would also keep the pool VPN as a separate network from LANs behind ASA. The LAN 10.45.0.0/16 and 10.45.99.100 - 200 are on the same network.

  • Satellite C660D - error 651 attempts to connect to the internet via modem

    Hello

    I'm so stupid with this stuff so please make all responses for a 3 year old can understand.

    The problem - since a few years, I used a desktop computer and connected to the internet via modem wide empty tape and USB connection. Last week bought a Satellite C660D installed Windows 7 os provided and tried to connect with my modem, but failed miserably.

    I get the error message 651 but do not understand why.
    I use wired ethernet (because my friend does on their laptop) and tried the cable on their system, and it worked very well, so I don't think it's that.

    If someone is kind enough to explain what I do, I'll be able to keep this computer connected to the internet with usb and connect the laptop with an ethernet at the same time, so I can read the instructions while I go or I'll have to print the instructions and disconnect the Office before retrying the laptop? Yes, I'm dumb and I'm not even blonde, lol

    Thanks in advance for those who have the patience to try to help me.

  • Satellite A60: Unable to connect to the internet via a modem - no dial-up

    In my Satellite A60, WinXP Home, when I try to connect to the Internet via the modem of Toshiba, I get error 6: handle not valid, and after a few attempts, I get error 50: all devices connected / request not supported.

    Device Manager / network / card Asynchronous RAS displays an error (black exclamation point on a yellow background).
    The driver is asyncmac.sys = MS Access Remote network serial driver.

    I have:
    -tried to uninstall the RAS asynchronous card, but no luck, didn't say it may be necessary to start
    -modem uninstalled / reinstalled
    -update of Windows XP through windows update
    -update of the bios / modem / network drivers from Toshiba

    No luck, the RAS asynchronous card error is still there.

    Any suggestion?
    Thank you
    Alessio - Italy

    I think that this problem is Windows XP and map Asynchronous RAS, not the modem.
    The modem correctly composed the number, negotiates the user and the password, and then I get error 6 and 50.
    On the internet I found this tip for uninstalling and reinstalling the RAS asynchronous card:
    http://forums.practicallynetworked.com/showthread.php?t=6781
    I followed the instructions and run RArepair.exe.
    It uninstalls and reinstalls the map Asynchronous RAS, but RAS is still in error (the yellow field in the Device Manager).

    How can I connect to my Personal Hotspot iPad2?

    Thank you

    Phill

    Hi Phill,

    A Hotspot is limited to a certain speed by the operators. Access point might not meet the requirements for streaming the video data on the Internet.

    So, the Home Theater system cannot be connected to the Hotspot.

    The Internet speed should be 2.5 Mbps for SD videos streaming and 10 Mbps for streaming HD videos.
