How do I get LabVIEW to recognise a Gaussmeter as a device through COM port 1?

Hello everyone.
I am trying to do display the readings from a GM05 Gaussmeter in LabVIEW through COM Port 1 on my computer.  I have installed the relevant drivers and MAX recognises that something is plugged in by listing COM 1, COM 2 and LPT 1 under devices, but it does not recognise the Gaussmeter as a device (it does not say 'device #' in brackets next to COM 1)..  Therefore when I come to create a new Virtual Channel in the Data Neighbourhood I cannot select my COM port as a device.  Can anyone help me to solve this problem, any advice would be greatly appreciated.
Regards,
Rob.

Unlike GPIB the com port or serial communication usually does not have an identify query, so it wont auto recognize the device.  You should look in the manual of the device and send an appropriate string (there might be a self-test or identify string) and check for the correct response.  Not all devices communicate both ways (some are talkers, some are listeners and many are both).

  • HT1473 I want to keep my music on my external hard drive to free up room on my computer how do i get itunes to recognise the hard drive to play the music?

    I would like to keep all my music on my external hard drive but I can't seem to get itunes to recognise my hard drive.  How do I get itunes to recognise my hard drive so I can play the music off there rather than copying the files over each time?

    Click the icon to launch iTunes
    Immediately press and hold down the shift key
    Keep holding shift until asked to create or choose a library
    If iTunes opens normally close and go back to step 1.
    Browse to the iTunes Library.itl file you want to open.

  • When i download a file from the web i get "Anti-Virus Program not found " message. This has been happening since I change anti-virus programs for CA etrust to Sophos. How do I get Firefox to recognise my new Anti-virus program?

    every time i download a file from the web (ie. a PDF file) i get "Anti-Virus Program not found " message. This has been happening since I changed anti-virus programs for CA etrust to Sophos. How do I get Firefox to recognise my new Anti-virus program?

    That is a very good warning provided by the Download Statusbar extension. Something like that should been built into Firefox. I filed this Bug report a couple of years ago, about the lack of a warning like that. <br />
    https://bugzilla.mozilla.org/show_bug.cgi?id=480855 <br />
    I have looked everywhere that I can think of to find a list of '''IOfficeAntiVirus providers''' ''(as mentioned in the Bug report)'' that will work with Firefox, so I can't answer that for you.
    You might want to ask the developer of the Download Statusbar extension about it. He might know which AV programs are compatible with the Windows API that Firefox uses for the download scan. <br />

  • How do I get iphoto to recognise my external hard drive

    how do I get iphoto to recognise my external hard drive

    DO you mean, how to put a Library on an external?
    Make sure the drive is formatted Mac OS Extended (Journaled)
    1. Quit iPhoto
    2. Copy the iPhoto Library from your Pictures Folder to the External Disk.
    3. Hold down the option (or alt) key while launching iPhoto. From the resulting menu select 'Choose Library' and navigate to the new location. From that point on this will be the default location of your library.
    4. Test the library and when you're sure all is well, trash the one on your internal HD to free up space.

    Hi Mark, my problem is very similar. I have registered myself as Service Provider at the OCP member-only page, after it I have created my account on the ePeople site where I registered my certifications, but the status is "Pending".
    Does anybody know what to do?
    Mark, did you completed the first 2 steps that I mentioned?

  • IPhone **** cannot be used because it requires iTunes version 10.6.3 or later - I get this error message yet I have 10.6.4, how can I get itunes to recognise my phone?

    The iPhone **** cannot be used because it requires iTunes version 10.6.3 or later - I get this error message yet I have 10.6.4, how can I get itunes to recognise my phone

    You must be referring to OS X 10.6.4, because there is no iTunes version 10.6.4. You can download iTunes 10.6.3 here:
    http://support.apple.com/kb/DL1575
    Any reason why you have not updated to OS X 10.6.8? If you did, you could then run iTunes 11.0.1.

  • How do I get iMovie to recognise & allow me to use the built in iSight camera?

    How do I get iMovie to recognise & allow me to use the built in iSight camera?

    You do not mention what version of iMovie you are using, so I will assume it is the same as mine, iMovie '11, version 9.0.8
    When you launch iMovie you should see, just above the Event Library, a camera icon. Click that.
    Once you click it you will see a new window labeled "Import From: Built-in iSight." In the bottom right corner there will be a button labeled "Capture." Use that when you are ready to capture your video.
    Best of luck.

  • How do you get iTunes to recognise new/changed Airport names? These Airports have attached speakers.

    How do you get iTunes to recognise new/changed Airport names? These Airports have attached speakers. Itunes showes the old names of these Airports but they have been renamed in a newly reconfigured network. Itunes will play through the attached Airport attached speakers. The Airport utility shows the correct new names.

    Hi turingtest2 - thanks for the reply. As you say It is how it is - and I have three workstations in this home (not counting three for my children and one for the family) and I pretty much always have more than one OS on each - that's how it is for me. I shouldn't have to worry about how many OSs I have (or how often I change them) just to have music while I'm working - through the PC sound system that is. I never have to worry about any other software, only iTunes. Once in a while (in the past) I've made a vendor call if I changed to many things to often (like CPU, GPU, memory, etc - or even a replacement MB) - but that hasn't happened in a couple years (at least since Vista) so I think (hope) they have fixed that for good. And even then it was a quick call and problem resolved. The only (glaring) constant problem is iTunes - limiting my own use of my own music (by counting an OS as a physical PC). Even with VM (which is just another OS) - although you can Attach things to multiple active OSs - it's still your own (purchased) music - and all on one PC. Thanks again!

  • How can I get iTunes to recognise 2 different iPads?

    Just bought a new iPad2 but when I connect to iTunes, it thinks it's another iPad we have in the family (we share the usic library). How can I get iTunes to realise it's a different device?

    That is one of the most bizarre things that I have seen reported, but nothing is impossible.
    Quit iTunes, restart your computer, reboot your iPad and then connect it again.
    Reboot the iPad by holding down on the sleep and home buttons at the same time for about 10-15 seconds until the Apple Logo appears - ignore the red slider if it appears on the screen - let go of the buttons. Let the iPad start up.

  • How do I get the correct ICloud account on my iOS devices?

    Hello. A few days ago, I changed my Apple ID username from my old email to my new one. Everything worked fine and I was able to re-login to the App Store, iMessage, etc. A few days later, I got a message from iCloud asking me to login. When I tried to login it failed and I realized that it was using my old Apple ID email to login to iCloud. So I went into accounts and tried to delete that account and add the account with the correct Apple ID. When I tried to delete the account it asked for my iCloud password to confirm, which doesn't work because it is using my old Apple ID. I then tried to add my current iCloud account without deleting the old one, but when I did it said it was already on the device. How do I get the correct ICloud account on my iOS devices?

    Log out of the old ID, then login using the new one with the correct pw.

  • Since update of my MAC my Notes no longer appear on my Mac but are still available through iCloud on my iPhone and iPad. How do I get my MAC to sync with the other devices as e'thing else has synced on my MAC through iCloud.

    Since update of my Mac Book Pro my previously drafted Notes no longer appear on my Mac but are still available through iCloud on my iPhone and iPad. How do I get my Mac to sync with the other devices as e'thing else has synced on my MAC through iCloud. Also since the update Notes no longer appear as a folder in "Mail" but are now a distinct programme-is there any way of returning Notes to the Mail programme?

    Thanks, but I've been on the phone with AppleCare US (where I am and live) and AppleCare UK. They continue bouncing me back and forth without helping resolve the problem.
    Perhaps someones knows how to further escalate the issue at Apple?

  • How do I get Adobe reader to be recognized on my Devices and Printers?

    How do I get Adobe reader to be recognized on my Devices and Printers?

    CutePDFWriter is a third-party application, which Adobe doesn't provide support for. But, I did find the following on their website:
    "Requires PS2PDF converter such as Ghostscript (recommended).
    You can get the free GPL Ghostscript 8.15."
    Here's a link to their website:
    CutePDF :: Product :: CutePDF Writer
    So, it looks like it creates a PostScript file for you, but then you need additional software to convert the PostScript file to PDF.
    Best,
