Multi-Function-Synch AO-Write Dig Chan.vi

Bonjour,
Ce post est en rapport étroit avec ce dernier :
NI Discussion Forums : La communauté française : Discussion de produits NI : Le terminal source à co...
Où on m'avait suggéré un exemple montrant une sychronisation de deux tâches d'acquisisitions (1 analogique + 1 numérique) Multi-Function-Synch AI-Read Dig Chan.vi J'ai donc reproduit cet exemple en transformant les tâches d'acquisitions en tâches d'écritures... Et là, surprise, cela ne marche qu'à moitié : seule la voie analoqique sort un signal.
Je vous joins une copie d'écran de mon diagramme, en espérant que vous pourrez me dire ce qui peut bien m'échapper.
Merci d'avance pour toute aide.
Cordialement,

Bonjour,
Effectivement, merci de me l'avoir signalé, mais il ne s'agit que d'une faute de recopie... En ayant correctement défini deux tâches de sortie (numérique et analogique), seule la sortie analogique fonctionne. Je précise que je dispose d'une carte ni USB-6259. Dans mes recherches je suis tombé sur ce post qui explicite un point des caractéristique de cette carte :
"622x, 625x and 628x M Series DEvices all have correlated digital I/O on port 0, meaning they must use an external sample clock." - John Passiak -
Qu'en pensez-vous ? Est-ce pour cela que j'ai tant de mal à faire avec le numérique ce que je fais très facilement avec l'analogique ? Est-ce pour cela aussi que je ne peux pas candencer une horloge d'échantillonnage avec OnBoardClock pour source ?
M. Passiak cite ensuite les 621x et 623x : Est-ce que j'aurais rencontré les mêmes ennuis avec l'une de ces cartes ?
Cordialement,

  • Multi function synch AI-AO

    Hello all,
    I would like to synch the Analog input and two separate Analog outputs (Ao0,Ao1) of a NI-6040.
    I first used the  multi function synch AI-AO vi from the examples and added a second AO as picture 1 indicates, without synchronizing and it worked fine.
    But I also want to synch the second AO (Ao1) with the acquisition. I tried this as pic 2 states but it always indicates "error: 50103 the specified resource is reserved"
    Does anyone know how to do this??
    Thanks,

    Hello Adao,
    Actually, you will find an explanation in the following document : Simultaneous Analog Output Tasks on the Same Device.
    The solution to use only one task is the only solution.
    This is due to the fact the all Analog outputs use a single clock, so-called AO Sample Clock. It is not possible to create different clocks for the outputs of a single card.

    Hello,
    I am trying to read the task name, channel name, and physical channel from a configuration file and using this information create a DAQmx task and two global virtual channels. Everything seems to be working ok (no error) until I am trying to write to one of the channels, then I get an "Error -200428 occurred at Write Dig Chan.vi". What am I doing wrong?

  • Fax via Network Multi-Function Printer

    I own a HP Multi-Function device to print, scan, fax, etc. My home network is set up to PRINT wirelessly from my computer to my printer, but for some reason I am unable to FAX wirelessly. As of now I must first print the document then fax it manually, when I'd much rather skip the middle steps of printing and just fax it directly using my network. The only way I can send a fax from my computer is bypass my wireless network and plug directly into the HP printer via USB. I think if I can print wirelessly why can't I fax wirelessly too? Any suggestions?

    TC (and airport extreme) peripheral support falls into universal (ethernet) and special (usb).
    Anything that can be connected to the ethernet port will be translated through the wireless system and work just well (or not well) as it would if connected via ethernet. Devices plugged into the USB port (directly or through a hub) require special support by Apple. Apple writes drivers for these and adds a tab to the airport utility software. This used to be just printers. Currently, this is limited to printers and hard drives. MFCs go beyond the simple printing function Apple is trying to support via USB.
    In my case, I have a Brother 7820n MFC. Its designed to operate over ethernet. Plugged into the TC, this means printing, scanning, and faxing (right out the phone jack) wirelessly - from every computer in the house.
    Does your MFC offer an ethernet upgrade?

  • Multi-function printer compatibility

    I have read in a few places that a multi-function printer (print, scan, fax, copy) will not work with all of the computers on the network plugged in to the USB port of the time capsule
    to anyone that has the time capsule, is this true?
    will all computers on the network be able to print?
    because it is not too crucial for me to be able to scan to and fax from other computers on the network, will the scan and fax functions be usable on at least one of the computers?

  • What's wrong with a multi-functional audition?

    Nobody wants to pay for a multi-functional software when they're only going to use a portion of that functionality for the work they do.  But if making it multi-functional means that the program endures and continues to evolve, then why not just do the math (ie decide if the price of an upgrade is worth it) and ignore the bits you don't use?  For instance, I would describe myself as a 10% user of Audition - I reckon I use about 10% of what it has to offer - but I'm happy to have that other functionality on board as long as I can do what I want to do.  However, recently I've started using MIDI, and that's why I'd be happy if Audition had MIDI functionality.  More recently still, I've started getting involved in video, and so I'm happy that Adobe's treating Audition as a software for video editors.  And those two instances seem to be occasions on which the program offered something I was moving into, which *might* be an argument for 'Audition's good even if it does do stuff you're not yourself the least bit interested in  - somebody's gonna benefit from this, even if it isn't me.'  Somewhat selfless - yeah, I realize that. But if you can think of a better forum to have this discussion in, then take it there.

    I am not sure if I follow you completely on your work-around.
    Everything I have to say on this topic is based on obesrvations and threads I have read on Info-LabVIEW. Therefore it is subject to corecttion by those who know better.
    LV is smart enough to know when "something" that had been opened, can be closed. It is not perfect.
    If for instance you open a VISA refnum and pass the refnum  to a LV2 AS A REFNUM the refnum in the LV2 stay alive as long as the VI's are running.
    If you start another VI that uses the LV2 to fetch the refnum, it should get a valid ref as long as it starts before the first goes idle.
    You then be able to work with refnum usign the VI launched second as long as stays active.
    I often create action engine that can be invoked where required throughout an application. If the action engines get a ref in one state (like init) and use it another, I will generally write a "tester" that calls the action engine action to test the engine. In this case, my "tester" stays live and it keeps the ref's fresh.
    I suspect if you tried to trick LV you could. If you type cast the ref nums to I32 and stored those in a LV2, I could see how LV could loose track of the resource sharing, but that is something I would avoid.
    So I encourage you to do some experimenting with keeping track of who's running when to see if your work-around will work.
    If you think you understand it better than I explained it, please post.

  • Printing Booklets to an HP Color LaserJet 9500w/Multi-Function Finisher

    I work for a private art school with a strong Graphic Arts program. WE recently purchased a Multi-function Finisher for our HP Color LaserJet 9500 hdn which has duplexing capabilities. Weve run into a road block trying to output booklets from InDesign that are saddle-stitched, folded and stapled.
    The HP support people are recommending that I take a step backwards and try outputing from MS Word. Not really an option at a school where we consider the page layout standard as Adobe InDesign.
    If anyone can shed some light on workable settings for this in CS3 please contact me at: [email protected] Many thanks.

  • Wireless print server that suppports multi-function?

    I have a family member who has an HP multi-function USB only printer (can't remember the model offhand). They are looking to get a laptop soon. I was also gonna then hook them up with a wireless router for their home & DSL connection. The current HP printer is USB, but I would like to somehow make it wireless. I have used several wireless print server devices for USB printers, but none of them support the multi-functions (scan, copy, fax, etc) and simply allow you to do basic printing wirelessly. Short of buying a totally new wireless printer and/or network printer of some sort that can plug into the router & then handle all these functions wirelessly, is there possibly any wireless routers or wireless print server devices out there that will FULLY handle HP multi-function printers?

  • 10.6.8 Snow Leopard loses HP multi-function scanner connection when users are switched.

    I've got 10.6.8 (Snow Leopard) installed on an iMac with a USB attached HP multi-function printer/scanner/fax.
    I've removed all HP software and got the latest HP drivers from Software Update.
    The software was able to scan appropriately using Preview and Image Capture until my wife signed onto the computer using her id.
    (She switched users and logged into her account on the same iMac.)
    Upon switching back to my user id, there was 'No scanner detected.'  I removed and re-added the printer.  No luck.
    (In fact, upon re-adding the printer, the connection just showed 'USB' instead of 'USB multi-function', and doesn't find a scanner.)
    Rebooting solves the problem (until the next time we switch users).
    Anybody have any ideas?
    Thanks,
    Jimmy

    Is it possible to run the Macgames Realmyst disc on Snow Leopard10.6.8 at 64bit?
    I believe RealMyst is a "pure" is only PowerPC.  So it doesn't matter whether you boot in 32 or 64 bit but it does matter whether you installed Rosetta on your system (optional when you installed your system) to handle the ppc code.  Even with Rosetta there's no guarantees that app will run in 10.6.8.
    Also RealMyst is for OSX.  SheepShaver is for emulating Clasic OS9 so forget about that.

  • Have an Epson workforce 600 worked fine until new router and Lion installed.  Now when I try and scan with the all in one I get a "POWER PC APPLICATIONS ARE NO LONGER SUPPORTED"  and my IMAC does not recognize that the Epson is a multi function printer.

    Installed a new router.  Installed Lion. Have an Epson Workforce 600 multi function printer.  Two problems. 
    1. I cannot get Lion to recognize that the Epson is a multi function printer.  There is no scan option on the "print/Scan" popup window.
    2. When I try and use the epson scan utility I get:  POWER PC APPLICATIONS ARE NOT LONGER SUPPORTED.
    I have tried EPSON support with no real luck as they say it is Apple upgrades that are the problem.
    Apple support was quite rude..said it was not their problem and that I should call epson.  Told the I did but it made no difference just got the same reply.
    Have no idea what to do.....seems I cannot find out which multi-function printers Lion supports.

    Not to give you another run around, but you need new printer drivers from Epson for your printer so it works in Lion.
    Now it could be that they are working on it, or that they could have decided not to provide new drivers in order for you to force upgrade.
    The only thing a user can do is decide very carefully BEFORE upgrading to a newer Apple operating system, make sure that all their current hardware and software works and make a decision for themselves.
    Since you upgraded to Lion, you can go back to Snow Leopard and your PPC software will work.
    Do you need instructions?

  • Can someone recommend a good multi-function scanner/printer/copier that works with Mac OS 10.6.8?

    I've just purchased a Canon Image Class MF4570dn. Very disappointed to find that whatever I do I cannot get the scanner to work & the Apple support board is of no help.
    It seems like there is a conflict with OS 10.6.8 that does not let the scanner get recognized by any scanning software -- either the Mac native software in Preview or the Canon software included on CD with the box & via download from Canon's site. The Canon software is called "MF Toolbox" but for the life of me I can't get it to start without instantly crashing!
    Any suggestions of set-ups that are working with you on a similar system set-up would be much appreciated!

    This is  discouraging! I ended up trying Canon because my Macbook Pro suddenly stopped recognizing my previous HP scanner -- a MF inkjet printer.
    I have been looking at HP multi-function lasers in lieu of this faulty Canon I just returned.
    I intend to be doing very simple things with whatever MF unti I end upw ith -- no printing or scanning over the network. I'm happy to connect it directly to my computer via USB. So I'm not sure I'd experience the problems you are having.
    Maybe I should go w/ one of these Brother units? Is there anyone on this board that can attest to these machines working with MacBook Pros?

  • Faxing from Mountain Lion with a multi-function printer

    I recently upgraded to Mountain Lion from Lion. Of course, my Apple external modem hasn't worked since the initial upgrade.
    I hadn't done too much about this, but it really is awfully convenient to fax from my computer, vs. printing something out and putting it in the fax machine. (I have a stand-alone one.)
    I DO have a Canon multi-function printer (the MX870). When I set it up (which was a nigthmare) I didn't setup the fax portion because I HAVE a fax.
    But now ... well, I'm tired of not being able to fax from my computer. So I know I SHOULD be able to, but I haven't been able to get it to work. I connected the phone line (it's on a splitter with the other portion going to our comcast cable modem.) But it's not visible via the "add print or scanner" preference. The manual is less than clear.
    Do I need to add some Canon software? I'm not at home now, but I'm thinking I'll try that next.
    Any help wold be much appreciated. I know I could buy a new external modem, but as I'm about to purchase a new Retina MacBook pro, I'd just as soon not!
    (P.S. Perhaps this goes in networking.)

    Yes absolutely.  I set it up last Fall and have been using it until last week, at whick time I lost wireless connectivity with router for no reason at all.  I can not remember how to do it now and I am looking for the answer myself.

  • Best Multi-Function Printer Software Compatible with OSX

    About five years ago, I surveyed Multi-Function Color Laser/Scanners/Fax, etc.  I ended up with a Brother MFC9840CDW that I loved.  I had tried HP but their software was not as good, and too many features were disabled in OSX.  Brother supported almost everything and was reasonbly reliable.  While the scanning functions remains great, my old reliable Brother is getting a bit long in the tooth in terms of print quality and speed.  I am thinking of upgrading. 
    I would to love to find if anyone has experience with Multi-Function machines, particularly in terms of their software, for OSX.  I just picked up an HP LaserJet Pro 400 M401dw B&W, so not to put too much of a load on my color machine, and frankly, it is boss.  But it is not Multi-Function.  Can those who have experience chime in with who they think has great Multi-Function software for OSX, and even better if they have experience across different vendors to (briefly) compare.  It would be much appreciated.  Much of my focus is on flexibility and ease of scanning. 

    I second your inquiry. My Brother MFC7820N just died after 5 years. Was a great monochrome laser printer, scanner, and fax machine. The software always worked. I wonder how the MFC software of Canon or Epson compares?

  • Is an OCR app included with the purchase of a Canon MF216n multi-function printer?

    Just purchased this multi-function printer and the documentation seems to imply that I need to acquire an external OCR app.  Please confirm and / or clarify.  Or do I need to download an app from the web like Free OCR to Word?
