Can I directly communicate with an EnDat Sensor or do I need an interface?

We are using cRIO with FPGA and some DIO interfaces (NI 9411 and NI 9403). Until now we had incremental signals which are easy to detect with the DI module. But now we are have an absolute signal with this EnDat signal. Is there a way to add this signals (1Vss) ant the absolute ENDat interface with standard cRIO modules? We don't want to add an additional third party module as the EnDat Module from SEA.
Od do ou have other references to get an absolute signal?
Thanks

Hi Petric,
sorry for the questions, it's clear what you mean now. After some researches i can tell you, that it is the best solution to use the EnDat Signals is the cRIO EnDat Modul of SEA. National Instruments doesn't offer EnDat Modules, because we can't cover the whole spectrum of Modules and the EnDat Protocoll/Signal is very special and complicated. It ensures you reliable FPGA speed at a maximum data rate of 38 kHz and is a qualified product which is full supported from our cRIO Chassis. So if you want to use the EnDat Signal i would recommend you the Module from SEA. If it's possible to use other Signals like SSI, Hiperface you can look after other solutions.

    I am new to IPAD and I want o use facetime, how can I use it to communicate with my mac at home, do I need to create another account with a different email account

    do I need to create another account with a different email account
    Yes, the email addresses need to be unique to each device. You may use the same Apple ID on each device, but the email address used by each device needs to be different.

    Regardless, it is not a matter of carrier locking.  Verizon iPhone 5 phones were never GSM sim-locked to begin with.  Every iPhone Verizon has sold since the introduction of the iPhone 5 has been sold with an unlocked GSM slot, as required in the USA by their agreement with the FCC.  They have not been allowed to sell any iPhone 5, iPhone 5c nor iPhone 5s devices with GSM carrier locking in place.
    Your connection problems are from some other cause - it is NOT a carrier locking issue.

  • Why can't I communicate with both of my GPIB devices?

    I have 1 NI PCI GPIB board in my computer
    I have 2 identical devices (keithley 237) connected one at address 15 one at address 16
    and 2 different programs one program to connect with 15 and 1 to connect with 16
    after I tell the 1st labview program to communicate with 15 then I tell the 2nd labview program to communicate with 16. then both communications come back with error device timeout. one at a time, I can communicate find with either device.
    Why can't I communicate with two different GPIB devices at the same time?

    Hi mrutter,
    first I would try some other addresses, e.g. 5 and 11. 15, 16 could be
    a special address used by the controller.
    Are there any other devices on the GPIB? If so then there could be
    another instrument with the same ID. Do both (or all) devices show in
    MAX, and can you communicate with them in MAX (e.g. query a *IDN? )
    And are you sure that you *have* setup the correct addresses in the
    Keithley instruments (look in the manuals if you don't know how to
    change their addresses)? Some Keithley instrument are in local mode by
    default, and you must explicitely set them in GPIB mode.
    Sometimes, GPIB message termination can be an issue (although both the
    GPIB cards and the instruments seem to get more tolerant of this).
    Also, you must be very careful not to mix different versions of
    LabView drivers and LabView version. I once had three different
    LabView versions on a PC, it was terrible. We had to format the
    harddisk and start afresh since we couldn't remove all of the older
    versions.
    I first try all GPIB instruments in MAX. If all devices appear there,
    and I can query commands in MAX, then I usually write my own LabView
    drivers with the standard GPIB-read and -write VIs. I write them with
    my oldest LabView version (say 5.1), then I am sure they will work
    with all versions up to 7.1
    Actually I once had a project where *no* GPIB instrument worked 100%.
    We could never really find out what was the problem (it was probably a
    bad PC <-> Win98 <-> GPIB card <-> LabView 5.1 constellation).
    Good luck.

  • How can AII/OER communicate with ERP if both are in same system ?

    I have an ERP 6 EHP7  system with SAP AII/OER.   How can ERP communicate with AII/OER ?  Is PI/XI still required ?

    Hi @Denise Carew,
    One of the deployment options for SAP AII is that it can be installed as an add-on on the SAP ECC system. Not sure if deploying OER on the same box as SAP ECC has been an SAP approved/suggested deployment.
    When you say "I have an ERP 6 EHP7  system with SAP AII/OER" does that mean you have SAP AII component and SAP EM component installed at two different stages or has OER(AII+EM) been purposefully installed on SAP to be used as your enterprise repository?
    When AII is installed as an add-on to SAP ECC it will have access to the master data (like Product/Material master, corresponding GTINs, etc). There is no need to communicate this master data.
    But if you need to use "Secure Track and Trace" scenario in SAP OER then SAP PI is a mandatory software component. (Please refer to SAP AII 7.1 Master Guide section 2.4,Software Component Matrix, and other follow-on sections that explains this).

  • How can my applet communicate with servlet via HTTPS?

    hi all,
    I'm using jdk1.4.2_03. Tomcat 4.1.27/29.
    My applet used to communicate to serlvet/JSP via http protocol. However, I wish to apply SSL in my tomcat standalone. Is there any implication towards my existing applet to servlet codes?
    For example,
    URL servletURL = new URL("http://www.myhost.com/Shopping");
    // open connection between applet and servlet
    URLConnection servletConnection = servletURL.openConnection();
    servletConnection.setDoOutput(true); // allow connection do output
    servletConnection.setDoInput(true); // allow connection do input
    servletConnection.setUseCaches(false);
    servletConnection.setRequestProperty("Content-Type", "application/octet-stream");
    ObjectInputStream input = new ObjectInputStream(servletConnection.getInputStream());
    resultset = (Vector)input.readObject(); //get Object from Servlet
    input.close();

    http://java.sun.com/j2se/1.4.2/docs/api/javax/net/ssl/HttpsURLConnection.html
    I never used it though, you can check for some code here:

  • Can my computer communicate with my cellphone to transfer photos?

    I just got a new cellphone, and it has Bluetooth. It's a *Samsung SCH-u410* Camera phone. I was wondering if there was a way, via Bluetooth, to transfer the photos I take with the cellphone on my Macbook Pro?
    Anyway to take the pictures from my cellphone and put them on iPhoto via Bluetooth?

    To copy photos to your Mac that were taken with the iPad, copied to it via the camera connection kit, or saved from emails/websites then see this page - on a Mac you can use Image Capture, iPhoto and Aperture.
    To copy photos that were originally synced from a computer you will need a third-party app such as Simple Transfer which can copy them off via your wifi network. But as photos are 'optimised' when they are synced to the iPad, any that you then copy back to a computer may not be exactly the same as they originally were on your computer.

  • How can an ipad communicate with another ipad to show a presentaion from one to many others in the room with ipad

    Hi,
    I would like a ipad to talk to another to do a presentation . Ideally one ipad will be the main presentation tool and the owner will turn pages on his and then the other ipads will do the same without anyone touching them.

    1. Drag and drop or by selecting the pics you want to move and then clicking on the + button on the toolbar...
    2. Yes
    3. Select a pic and right click on it. Select Get Info:
    4. At this time you can only change dates on photos.

  • Can't communicate with the standby IP

    I can no longer communicate with the standby IP address configured on the inside interface of a secondary ASA5510. Just a couple days ago I could snmp, http, ssh, and ping it.
    From the switch that is directly connected to the inside interface I'm getting unexpected results when viewing the the arp table. The switch is saying the IP address associated with the ASA's inside interface has mac address 0023.3353.bcc8 but the ASA is saying its inside interface mac address is 0023.33bb.8362
    Furthermore when I issue the "sh mac address-table interface f5/46" command on the switch i see multiple macs on the interface that is connected to the inside interface of the ASA...

    Hi Bro
    Maybe the 5/46 has been configured as a trunk port? Could you paste your switch and FW config here, so that everyone here can assist you.

  • Can't Play DVD (with VLC, Totem, Xine, MPlayer), But Works in Windows

    I have a DVD that I can't play for the life of me in Arch. I've tried VLC, Totem, Xine, and MPlayer. And I do have libdvdcss installed. Other DVDs work fine.
    With VLC the DVD menu comes up, but when I hit play I get choppy sound and no picture. And I get these errors:

    With Totem I get the DVD menu and when I hit play it just freezes.
    With Gxine I just get a popup window that says "Media stream scrambled/encrypted" (but again I do have libdvdcss, libdvdread, and libdvdnav installed). In the terminal Gxine reports it's using libdvdcss to get the encryption keys and it appears to all go fine, but then I get the "Media stream scrambled/encrypted" popup window.
    Mplayer plays the the DVD but the image is scrambled and the sound is a little choppy.
    On the other hand, in Windows, on the same computer, the DVD plays fine with an older version of VLC (0.8.6d) and with Media Player Classic with the K-Lite Codec Pack.
    I'm especially baffled that VLC does it in Windows, but not in Arch (nor in Debian).
    Any thoughts? Thanks.

    That's interesting. I didn't realize it was all css. But how does that explain in this case the DVD did work with free players in Windows. As I said, both with Media Player Classic with the K-Lite codec pack and with an older version of VLC (0.8.6d)? Thanks.
    That is very possible. All those players use (or can use) direct show. As soon as you have the needed filter installed by SOME software all those players will be able to make use of it. And i think Vista even had dvd filters pre-installed.
    Btw. One of the more common protections on dvds is called arcos and is developed by Sony. Google for it
