Trouble communicating with GPIB-232CT-A

I can not communicate with my GPIB-232CT-A. I can send commands over the serial port, but I can't even get a light on the GPIB-232CT-A (except power and ready) to turn on. From what I have been reading, a driver is not necessary in S mode which I'm using. Is there a way in Java to make the GPIB-232CT-A recognize that I am talking to it? I have a mac with os X so none of the ni drivers will help. I am considering writing my own driver, but I'm not really sure about the syntax. I would be happy if the GPIB-232CT-A even somewhat recognized anything I send it.

Hi,
You do not need NI-488.2 drivers to talk to the GPIB-232CT-A in S mode. This is because it is simply a serial instrument in this mode. Have you gotten the device to work at all in S mode? A good way to check this would be to use a Windows PC and use Hyperterminal to talk to the GPIB device. Refer to http://digital.ni.com/public.nsf/websearch/61BA0EE248FB0B328625660B0066858D?OpenDocument for more information on how you can do this. If you are not able to do this successfully, then we may have an issue with the hardware. Please try this and let us know if you have any problems. Hope this helps.

  • I'm having trouble communicating with a transducer (Keyence LS-3100 laser scan micrometer) via the serial port. It works in Hyperterminal. Any suggestions?

    Its not a simple baud-rate or parity error. If I issue the command to send data (X1) in hyperterminal I start to get data. If I then switch to Labview I still get data. However if I try to issue the send-data command via Labview I get nothing (i.e. I can read from the device, but not write to it).
    I am on a Windows 98 (version 2) PC, running Labview 5.1.1

    Try adding a carraige return to the end of your command.

    Welcome to AD!
    I have a regular post for the top 3 or 4 fixes for that 9808 error. Obviously you are going to skip #1, since you've already tried it. Let me know how you get on with the next 2.
    The top 3 fixes to itunes error 9808 seem to be
    1) Go to Start > Control Panel > Internet Options > Advanced, make sure that SSL 3.0 is checked and TLS 1.0 is checked. Also under Security make sure that the “Check for server certificate revocation (requires restart)” is unchecked. Then click ok and fire up iTunes.
    2) The culprit was Norton. The users are set up as Admin and Standard. I have Parental Controls turned on in both Vista as well as Norton. Admin users had no problems connecting to iTunes. Standard users would get the error. I had to go to Norton’s Personal Firewall and add the program “iTunes Helper.exe” and set the option to “Allowed” (”iTunes.exe should already be in the Allowed category.) in order for the standard users to be able to connect.
    3) close iTunes if you have it open right now. Then go to C:/Documents and Settings/username/Local Settings/Application Data/Apple Computer/iTunes. Delete or cut the preferences.xml file which contains your iTunes preferences. Then go to C:/Documents and Settings/username/Application Data/Apple Computer/iTunes and delete or move the preferences.xml file. For Mac users, there is only one file you must delete or move a to a new location and is located at User > Library > Preferences > com.apple.itunes.plist. Restart iTunes and it will recreate those two (or one) files with the default settings. Feel free to set your preferences back to what they were and then connect to the iTunes store and enjoy!
    And #4, see if you can get into the iTS from a different windows admin account on the same PC.

  • Establishing communication with GPIB devices

    I am a newbee to GPIB and a novice at VB (6.0). Have been unable to establish communication with devices from the VB .exe. I think I am not declaring something in the right place? Any suggestions?

    TG,
    What kind of trouble are you having reading data from the instruments? There's information that addresses some of the common issues about why communication with instruments might fail. For more information, please refer to:
    Why Can't I Communicate with My GPIB Instrument?
    A couple of useful tools that you can use to check out communication to the instrument before writing your Visual Basic app are NI-488.2 Communicator and
    Interactive Control (IBIC)
    If you are still having trouble after trying out some of the suggestions listed above, it would be helpful if you capture the ibwrt and ibrd calls using NI Spy, save the Spy capture, and then attach it to this forum. If you are unfamiliar with Spy, here's a link with information about how to use Spy:
    NI Spy
    Hope this information helps with getting data back from the instrument.

    If you tried every possible solution in the all those links baltwo provided, there is nothing more anyone here can suggest other than waving a wand over the computer or you throwing salt over both shoulders. 
    Take the computer to an Apple store or an AASP.  Whichever is more convenient for you.  Let the geniuses there figure it out.  Diagnostic testing is free.

    Thanks for the flag J.K. - they contaced me and solved my problem.  On this account (which I created just to ask this question), I log in with my email rather than my user name (mtalldud). On the account that I was having trouble with, they told me to use my user ID instead of my email to log in and it worked. This is a bit confusing and seems a bit inconsistent but at least I don't need this temporary account any more to get into this community and find answers!

  • GPIB communication with GPIB (NI PCMCIA-GPIB)card in Visual Basic

    I have a old program in Visual Basic which works fine in windows 98 using the desktop, but using my laptop with windows 2000 on it and NI PCMCIA-GPIB card it fails to communicate and running the program does not recognize the sendIFC command. I am new to VB, so can someone tell me what am I missing here. thanks

    Hello,
    Is the PCMCIA card recognized by the NI-488.2 driver on your laptop? Are you able to communicate from Measurement and Automation with your instrument? What do you mean it does not recognize the sendIFC command? Does Visual Basic give you a runtime or a compile time error? Are you using the latest version of the driver? (Usually 2.1 unless you're on 95 or NT with your card)
    You can try out the Visual Basic language examples in the 488.2 directory under Languages as these will let you know whether or not the driver is installed correctly.
    Let me know if you need more assistance by replying here.

  • Trouble Communicating with Document-Style Web Service

    I have a flash app that currently communicates with a
    RPC-style web service. I changed the web service to be
    document-style, and the flash app no longer sends valid requests. I
    was under the impression that one could simple swtich styles, and
    flash would play along. Apparently, this is not the case. Does
    anyone have an insight in this area?

    Clarified with Partick Calahan, who is maintaining this tool.
    Currently, doc style is not handled by this tool. I guess it will be
    supported in the future.

  • "Trouble communicating with iCloud ...try again"

    Several weeks ago I updated (managed)my Apple ID with a new primary email address and moved the old address to the alternate address.  Thinking that I was also updating iCloud, I deleted the old iCloud account and tried to add the new updated Apple ID and password. I cannot access iCloud in System Preferences. "Cannot communicate with iCloud --try again" is the response.  I have updated my iphone with new iCloud/AppleID information and all is well.  iCloud.com is fine.  Cannot log into AppStore with new Apple ID but iTunes works fine.  After reading and trying lots of things, I have learned that the original iCloud ID is the only one iMac will recognize.  I do not have that ID any longer.  Will I ever use iCloud on my iMac again?

    For those reading for the same issue, Atom has posted on two separate threads the same resolution and I can say that at least for me it did work.  Thanks Atom

  • LaCie DLB trouble communicating with DVD Studio Pro 4

    I have built and formatted my 5gb dvd properly inside of DSP 4. I have LaCie DLB External firewired in and set properly. When I go to burn the tray comes out, it muxes...but when the formatting begins it stops and I get this message; "Formatting failed. The recording device reported the error #6: Power on, reset, or bus device reset occurred. (0x29, 0x00). I know the burner works if I use Toast...but I want it to work directly from DVD studio pro 4. My question is...1) what is that message? 2) does dvd studio pro 4 and LaCie work together? LaCie says they don't support dvd studio pro 4. 3) would it just be easier to install a internal dual layer burner?

    Delete the "com.apple.dvdstudiopro.plist" before or after you install the update but before you repair permissions.

  • Troubles printing with networked printers

    I have a printer connected to a Mac Mini (with Leopard installed) and am trying to send something to print from my G5. The computer sees the printer but it always comes back saying "com.apple.print.recoverable-warning". Apparently it is having trouble communicating with the printer. The computers are connected through a wireless connection using a airport extreme base station. The printer is physically connected to the Mini since the usb has a external drive connected to it. There are no problems printing from the Mini but only when trying to do it from another computer on the network.
    Anyone have any suggestions?
    Thanks,
    D.J.

    I get the same message (com.apple.print.recoverable-warning), but my printer is on, plugged in to a USB hub which is plugged into the TC. I've re-started the printer, plugged it directly into the TC USB port, added it as a new TC printer to my printer list and selected it, but no change. I'm about to give up on shared printing with the TC and just plug the printer back into one of my Macs.
    Anyone have any other ideas? (Despite high hopes, the new Airport Utility update did nothing for me.)
