Position encoder works with PCI-MIO-16E-4 but not with PCI-6062E, why?

I am using A BNC-2090 to connect Agilent HEDS-6540 position encoder to my PCI-6052E. The application works fine with my 12 bit NI card PCI-MIO-16E-4, But with the new card I get extra counts in my position. ex 1052 pulses when it is only supposed to be 1000 counts in a complete revolution. This setup still works great with the old card, meaning I can just plug into the other card and run the same app on the same computer, just a different device number. I have not been able to figure this out.

You might be seeing the affects of dithing with your signal. I'm not sure why it would be on one board, though not the other, one counter must be more sensitive. Anyway, dithering is caused by vibration or other outside forces that cause small glitches that add to the count total for the counter. There is a way around this, and that is to use a counte convertor. There is a page on this website that tells how to make one. The link is below. I would sugget trying this to see if it will fix the problem.

  • HP LJ4mv wireless printer worked with OS 10.5.5 but not with 10.6.3 - help!

    My ancient HP worked with 10.4.11 and 10.5.1 thru 10.5.5 wirelessly. With 10.5.6 thru 10.5.8 installed, the printer did ot work and only the Adobe printer appeared in the Printer/Fax setup. With 10.5.5, I was experiencing random horizontal gray lines, polygons with gradient colors (cyan and magenta) flashing on and off and smeared dialog boxes and drop down menues. So, I upgraded to 10.5.8 and lost the artifacts and my wireless printer. All drivers are current (Software Update delivered/installed updated drivers today.)
    10.6.3 is now installed and I still do not have a wireless printer. The Adobe PDF printer pops up and in the Printer/Fax dialog, it indicates "Kind" as HP LaserJet 4V/4MV Postscript. The Default button is active but all other buttons are grayed out and my printer does not appear.
    Summary: the printer works, the wireless router works and the drivers are current.
    Q. How can I get my wireless printer back? I need it badly.
    Thanks.
    Leonard

    Kappy, thx.
    The driver that is appearing now with the Adobe printer worked fantastically with 10.5.5, HP LaserJet 4V/4MV Postscript. This is from Apple, I believe. My printer does not show up when + is selected in the Print & Fax dialog and the Printer Name/Kind list appears. Only the Adobe is there.
    I d'l'd/instld the Gutenprint. I cannot select it until the printer appears in the Printer Name/Kind field.
    What is SL? :S
    Greg, thx.
    The printer is cat 5 to the ISP's wireless router and I am wireless. This has always worked up to 10.5.5. I incrementally d'l'd os upgrades 10.5.6, 10.5.7 and 10.5.8 and found the printer would not appear when I tried to add it. With Leopard, up to 10.5.5, my printer appeared automatically and I just had to make a selection from the "Print Using:" drop down.
    Bruce, thx.
    AppleTalk was a part of the setup and in 10.6, I cannot find AppleTalk. So you may be right about the IP route. Would Apple change this in the middle of Leopard with 10.5.6 (it worked up to 10.5.5) and not with 10.5.0 or 10.6.0? Would there not be an announcement that AppleTalk printer support was ending? No one in these forums knows that AppleTalk printer support was ended (I first posted in the Leopard forums)?
    Sorry for the skepticism. I just did not think this was a possiblity but maybe you are right.
    Is there a way to get an Apple reading on this? Should I set up a print server for wireless access? Any other suggestions?
    Thanks again all. I much appreciate your help.

  • Printing from web pages is excruciatingly slow with most recent upgrades of Firefox .Use an iMac and an HP officejet printer. Printer works fine with Safari and woodprocessed files, but not with Firefox and web pages.

    Printing from web pages is excruciatingly slow since downloading most recent upgrades of Firefox Mozilla. I have a desktop iMac, OS 10.6.8, and an HP officejet printer 4500 G510n. The printer works fine with the Safari Browser and with woodprocessed files, but not with Firefox and web pages. Help please! It used to print fast with earlier versions of Firefox.

    Hello and welcome to the Apple Discussions Forum.
    I have hardly any experience with HP printers but since your posting has not been replied to yet I thought I'd offer some assistance.
    With the printer status and ink levels working, it shows that you have a connection to the printer. So I would look at the issue being with the protocol being used for the print queue on the Mac.
    Since you have XP and Vista working, I would check the printer queue configuration on either box. In XP, go to the Properties and select Ports. Click the Configure Port tab to view the connection. If you are using RAW, then this is known as HP Jetdirect-Socket on OS X. So if you are not sure what protocol was used before I would create another printer queue, this time selecting IP > HP Jetdirect-Socket. Then enter your IP address and select the K5400dn from the Print Using menu.
    If this still fails to print then please reply. There may be limitations with adding the HP driver this way that I am not aware of. There may also be other driver options you can look at, such as HPIJS. If Greg Sahli reads this posting he has expert knowledge on this matter and will be able to offer some guidance.

  • Errors with sdk 1.4.1, but not with 1.3??

    I just upgraded to the j2sdk 1.4.1 yesterday from 1.3, and I'm getting a weird compile time error from an import statement that never used to happen. I'm just importing another class I've made, other imports from java.util etc. work fine, but not classes that I have made. Here's the code that gives an error.
    import java.io.File;
    import java.util.Vector;
    import java.util.Enumeration;
    import listDir; // only this line gives an error
    and here's the error.
    C:\kevin\listAll.java:4: '.' expected
    import listDir;
    ^
    1 error
    Anyone have any idea why that happens? Have the rules changed for importing since sdk 1.3? This worked just fine 2 days ago with 1.3. Thanks for any help.

    Hi all,
    This is what I found will work with the stand alone classes (not package classes).
    1) Do not use import MyClass; in your java app.
    2) MyClass should be in the same directory as you java app, unless you have set up your CLASSPATH to point to MyClass.
    Here is the listing
    //import MyClass;
    class HelloWorldApp {
    public static void main(String[] args) {
    String strNewPwd = null;
    System.out.println("Hello World!"); //Display the string.
    MyClass myClass = new MyClass();
    //Do something to call your class
    System.out.println(myClass.getMsg());
    It seems to work now. If someone knows where I can find an updated documents on how to include classes on 1.4.1, please reply to this message.
    Beside this problem, I am trying to use Tomcat 4.1 to develope a web application. I have similar problems finding my classes. On Tomcat 4.0, the app runs fine. I've try the above work around (not include import MyClass), but still does not work. Any suggestions?

  • Formatting of a chart works on a vi in labview but not with the same program as a .exe

    I am trying to make a labVIEW program into an exe using the application builder. I have managed to fix the other problems I encountered but there is one that I cant figure out. On the main screen of my program there is a chart with a drop down menu that displays different information. There is a subVI that I made to change the size and number of columns of the chart depending on the item chosen in the drop down menu. This seems to work fine in the program when run using labVIEW, but once I made it into a .exe file, the width and number of colums seems to have defaulted and will not change for each item chosen in the drop down menu as it did before. I am sure that I included the vi
    that controls this, but i cant seem to get it to work with the program as an exe.

    I cant find the runtime menu file. Maybe I explained my problem incorrectly. I am not using a runtime menu, I am using a menu ring. . .if there is any difference. I am attaching an example of what I suspect is causing the problem in my program. If you still think I need to include the runtime menu file, can you tell me where I can find it?

  • ITunes Home Sharing with Apple TV2, works with one Win 7 PC but not with the other

    Hopefully someone out there can help with this, I have gone through all of the troubleshooting procedures that Apple provides, and have spoke to thier 'fast track' technical services department and we cannot resolve this. 
    My probelm is that Apple TV does not recognize my Win7 PC that has itunes running in Home Sharing mode.  In order to test my router, network configurationand the Apple TV, I put iTunes on a laptop on my network running Win7 as well, and the Apple TV had no problems sharing with that computer.  I have opened all of the ports in my firewall that Apple recommended, and tried to make it work both with and without my anti-virus software, but still no sharing of iTunes with this computer.  We are working with the latest version of iTunes and Apple TV, both updated today.
    Has anyone run into this problem?
    Thanks

    Yep - have had the same problem, especially since IOS5 came about and no solution has worked.  I've fought this one for a while, I come back to it every once in a while when I see something that might be a new tack but no joy.  I've also tried all that stuff, but none of them fix it.
    I can tell you a couple of things I have found out along the way:
    First off, there is some kind of issue with the Apple Mobile Service that causes it to not stay working.  If you stop the service and start it you may be able to make the sharing show up for a bit, but it will eventually disappear.
    Secondly, there may be a network routing factor to this too.  Apple doesn't like to use the same kind of protocols as many sharing schemes do, instead preferring something known as "Bonjour".  Bonjour uses multicast routing, and appears to either be programmed badly or in a non-standard way - or maybe there just is no standard.  In any case what you find is that it just doesn't work, and there is no current fix. 
    Keep trying though, maybe you can figure it out.  If you do, please come back and post what you did, I'd be very interested.  Sorry I couldn't be more helpful, but I can at least tell you that you're not crazy, there are others out there having the same problem with the same bleak outlook.  By the way, mine used to work until iOS5.

  • Lion, Mail, and Outlook. I can't get preferences in Mail to accept Outlook as the default mail program. Outlook works fine within the Office world but not with Preview or Lightroom (to choose two that I've tried today). Any ideas?

    As per the heading, I can't get Lion to accept Outlook 2011 as the default mail program. When I go through the Preferences in Mail to set the detault mail program, I can see Outlook, I can select it, but it doesn't "stick." As soon as I reopen Mail, Mail is the defailt mail program again. It also doesn't work though the Outloook Preferences menu. I'm a recent transfer to Macs, and could use some help. Any ideas?
    Thanks!

    There is a forum specifically for MS Office for Macs, just click Office for Mac Product Forums and post there, they should know.

  • JVM Crash: with jre 1.6.0_18 but not with 1.5.0_14

    Hello everyone,
    I got the problem that my JVM crashes when I am using the jre 1.6.0_18 but the same code runs with an jre 1.5.0_14. The code contains some JNI parts and
    is compiled with a JDK 1.5.0_14. The crash can not be reporduced within a debugger. The crash either occurs in the jvm.dll - as in the error log below - or when acessing the ntdll.dll.
    Any help is appreciated!
    Thanks in Advance!

    If I load a webpage with an applet (http://java.sun.com/applets/jdk/1.4/demo/applets/Fractal/example1.html) and then move to a non-applet webpage, and have the Java console up, it stays up (alive) for about a minute before it closes. In the case of my applet it closes much faster.
    When I refresh, the second instance of the applet might be starting in the same process as the first process which is in the middle of closing (I am new to Java and JNI, so I might be using the wrong terminology). But with JRE 1.6.0.25 I was not seeing the crash on refresh. It manifested itself with the update to JRE 1.6.0.31
    I did realize the codebase was wrong. This is what I have now:

  • Adobe Reader docs appear washed out and faint with Firefox 6.0.1, but not with Internet Explorer. Running Windows 7

    The PDF docs opened in Firefox are very light and the color of print is multicolored shaded. Different parts of display different shades of any color but black. Just loaded newest Adobe Reader, did not help. Previously running Reader 9. Haven't had a problem till Firefox 6. If I fool with the Window Color in 7 I can effect the PDF doc. Lowering saturation level to nothing helps, but doesn't fix problem.

  • Ora-01882 "timezone region not found" with 3.0.03.97 but not with 3.0.03.45

    I installed the version 3.0.03.97 of SQL-Developer and now get an ora-01882 when I connect to a DB. I don't get this Problem when using version 3.0.03.45.
    Putting "AddVMOption -Duser.region=DE" in the sqldeveloper.conf didn't solve this problem though.
    The problem happens both with the connection-type "simple" and "TNS".
    I am on 32bit Windows 7 Professional.
    Java JDK is jdk1.6.0_23.
    Oracle Instantclient is 11.1.0.1.0
    Database is version 9.2.0.1.0
    Anyone got this problem too? What changed between both versions of the SQL-Developer?
    Regards
    Markus
    Edited by: Charon on Mar 24, 2011 11:52 AM

    I found something but need confirmation:
    SQL-Developer says my timezone is "Europe/Berlin".
    If I run this:
    SELECT *
    FROM   V$TIMEZONE_NAMES
    WHERE  tzname LIKE 'Europe/%'I get no hits with "Berlin" in it but quite a few others.
    One of them is "Europe/Istanbul".
    If I now add "AddVMOption -Duser.timezone=Europe/Istanbul" to my sqldeveloper.conf I can finally connect to my Database!
    So does version 3.0.03.97 of SQL-Developer somehow check this view for available timezones? Did the previous version not check this? Whats the solution for me then? (using the Istanbul timezone here doesn't seem right to me)
    Regards

  • RemoteFX Display problems with Windows 8.1 VM but not with Windows 7 VM running on Hyper-V VDI Server 2012R2

    Has anyone seen anything like this?
    After many, many, hours of wading through and eliminating potential variables the issue has been narrowed down to being present with a Windows 8.1 VM and not on Windows 7 VM.
    The problem is with glitchy display issues (Random Pixellation, Fuzzy Screen areas, Entire Screen filled with random shapes/colors etc.).  
    This is a Server 2012 R2 environment it is running Hyper-V Remote Desktop Virtualization Host.
    An Nvidia Quadro K2200 adapter has been enabled for RemoteFX and passed through.
    Also have tried Nvidia Grid K2 adapter. Both adapters use same driver set and multiple driver versions have been tested.
    Two Generation 1 VM's have been created.  One for WIndows 8.1, One for Windows 7.  All updates installed.
    Each VM uses the same set of Hyper-V resources, Virtual Switch etc.  (The settings for each VM are the same).
    With RemoteFX disabled on each VM the issue is not present on either VM.
    With RemoteFX enabled on each VM the issue is present on the Windows 8.1 VM and not the Windows 7 VM.
    There is no difference if only one VM at a time is enabled and running.  (Not GPU load related)

    Hi,
    Generation 2 virtual machines have a simplified virtual hardware model, and supports Unified Extensible Firmware Interface (UEFI) firmware instead of BIOS-based firmware. The majority of legacy devices have also been removed from generation 2 virtual machines.
    You can check below article might helpful for your case.

  • I can live with iphone 4 antenna problem but not with proximity sensor...

    I did not face much trouble with antenna issue.. may be I am having good signal.. but certainly I am facing proximity sensor issue.. out of every 5 calls I have problem with at least 2 to 3 calls going to mute or starting facetime or opening address book etc...

    I feel 100% the same. I am wondering if all these people complaint of the signal strength issue are really actually experiencing the proximity problem and just don't know it. This is beyond annoying.

  • I can not get Firefox to play music backgrounds on pages in browsers it works in IE and other browsers but not firefox, what HTML or Jave script do I need too use to make them work?

    I'm having a problem with firefox playing background music on some sites, it works with IE and other browsers but not with fire fox, what html or java script do I need to add to the pages so that they play the music?
    I develop my pages in Front Page and I know that the music only works in IE, so if someone can tell me how to correct this problem as it is important as I use fire fox as my main browser.
    I thank you in advance

    If a website uses BGSOUND then it will only work in IE.
    BGSOUND is not compatible with other browsers like Firefox.

  • I can use iMessage with all iPhone uses except for ONE person.  That person can use iMessage with all other users, but not with ME.  What's the problem???

    I can use iMessage with all other iPhone users that I communicate with, except for ONE person.  When I send to that person, it always goes through as a text message.  This person can use iMessage with pther people, but when they send me a message, it always goes as a text.  Why can we both communicate with other people using iMessage, but not with one another?

    Hi Russell,
    1) If you have OD set up and "editor" has UID 1111, then when they log in to any machine that's bound to OD as editor, they will get UID 1111. Therefore, there won't be any of these permission errors. This is typically the recommended approach.
    2) I assume you mean "You'd prefer to not using open directory?" Whatever the case, OD isn't mandatory with Xsan -- it's just that with multiple user accounts, managing them centrally tends to be easier. For 3 or 4 accounts and 3 or 4 machines maybe it's no big deal. If you go larger, it could get a lot more complicated. That said, if you set it up such that each machine has the exact same set of users (as you said, Mary = UID 502, Fred = UID 503, William = UID 504), then you can do what you want. Mary can log in from multiple machines at the same time, and in general you won't have permissions problems. Of course, if you try and read and write the same file from multiple workstations at the same time, you will get file locking issues, which will prohibit somebody from successfully writing the file.
    File locking issues are different from general permissions errors. The former basically says "hey, someone else is editing this file. Therefore I won't let you edit it right now... you can read it if you want though." Permissions means somebody saves it, and Xsan thinks you saved it and own the file, when you really don't.
