DAC output without using DAC configure mode

Hi,
I am using NI-5640R and labview 8.2.
Is it possible to send out anything without using DAC configure (single or quadrature) mode?
Actually, what I am trying to do is to send out to DAC whatever comes in, like attachment

ADC to DAC (FPGA).JPG ‏36 KB

Hi there:
I am also using the the NI PCI-5640R and I've been "studying" the program: "Frequency Translation", my intention is to modify it and produce a  closed-loop between I and O. 
I am also interested in transferring what i am reading through the
input port, directly to the output port but filtered and with a
phase-shift (final Objective: Q-Control). 
I need to visualize the signal in the HOST, so I need both FIFOS (DMA FIFO and  Local FIFO), and the "Quadrature Mode DAC Configure"
I would like to know:
1. How can I directly transfer the data acquired through the ADC port into the DAC?  (it is unclear due to the Event structure in the "Frequency Translation" example)
2. How can I configure the "Quadrature Mode DAC Configure.vi" for it to bandpass-filter the signal comming from the ADC at a given frequency and BW, specified by the user in the HOST?
3. Is it possible to configure the "Quadrature Mode DAC Configure.vi" to produce a phase-shifted signal (phase shift also specified by user in the host)
I've been working for almost 2 months trying to program the 5640R, doing examples, and modifying them.  After playing with different examples I've come up to the conclusion that the "Frequency Translation" example is the one that best-suites my application.  My problem now is that I AM LOST because i need more information regarding the configuration parameters of ALL the different VI's inside the NI-5640R VI Tree  to exploit them correctly, specially the "Quadrature Mode DAC Configure.vi".
Can anyone please help me?
Cheers, Antonio

  • Original photo size without using full screen mode...

    Like in Preview. Is there a way?

    You could use the Edit in Separate Window mode and enlarge the window as big as you'd like. The toolbar would still be there but you can cover up the rest of the iPhoto window if you'd like. The arrow keys will then let you scroll thru your photos.
    TIP: For insurance against the iPhoto database corruption that many users have experienced I recommend making a backup copy of the Library6.iPhoto (iPhoto.Library for iPhoto 5 and earlier) database file and keep it current. If problems crop up where iPhoto suddenly can't see any photos or thinks there are no photos in the library, replacing the working Library6.iPhoto file with the backup will often get the library back. By keeping it current I mean backup after each import and/or any serious editing or work on books, slideshows, calendars, cards, etc. That insures that if a problem pops up and you do need to replace the database file, you'll retain all those efforts. It doesn't take long to make the backup and it's good insurance.
    I've created an Automator workflow application (requires Tiger or later), iPhoto dB File Backup, that will copy the selected Library6.iPhoto file from your iPhoto Library folder to the Pictures folder, replacing any previous version of it. It's compatible with iPhoto 6 and 7 libraries and Tiger and Leopard. Just put the application in the Dock and click on it whenever you want to backup the dB file. iPhoto does not have to be closed to run the application, just idle. You can download it at Toad's Cellar. Be sure to read the Read Me pdf file.
    Note: There's now an Automator backup application for iPhoto 5 that will work with Tiger or Leopard.

  • Global Configuration Mode (Aironet 2600i)

    Hello to all,
    It's my first time in the forum, I thank any help possible. I bought a Cisco Wireless AIR-CAP2602i-E-K9 and have some practice on Cisco routers, but can not log in "Global Configuration Mode", not existe the command "Configure". How active configuration? Thank you for your attention.
    Helio Viegas

    Hello Helio,
    As per your query i can suggest you the following solution-
    Cisco IOS Command Modes
    The Cisco IOS user interface is divided into many different modes. The commands available to you depend on which mode you are currently in. Enter a question mark (?) at the system prompt to obtain a list of commands available for each command mode.
    When you start a session on the access point, you begin in user mode, often called user EXEC mode. Only a limited subset of the commands are available in user EXEC mode. For example, most of the user EXEC commands are one-time commands, such as show commands, which show the current configuration status, and clear commands, which clear counters or interfaces. The user EXEC commands are not saved when the access point reboots.
    To have access to all commands, you must enter privileged EXEC mode. Normally, you must enter a password to enter privileged EXEC mode. From this mode, you must enter privileged EXEC mode before you can enter the global configuration mode.
    Using the configuration modes (global, interface, and line), you can make changes to the running configuration. If you save the configuration, these commands are stored and used when the access point reboots. To access the various configuration modes, you must start at global configuration mode. From global configuration mode, you can enter interface configuration mode and line configuration mode.
    For more information please refer to the link-
    http://www.cisco.com/en/US/docs/wireless/access_point/12.2_15_JA/configuration/guide/s15cli.html
    Hope this will help you.

  • PCI-7352 DAC Output

    I'm using the PCI-7352 to drive a Physik Instrument C809 amplifier and M230.25 linear acuator.
    I've run into some issues with the speed and following error.  I've finally been able to track down that the DAC seems to be operating around 5V as it's 0 velocity point (based on the output from 1-D interactive in NI-MAX and also in the Read DAC.vi during motions).  Basically, if the voltage is >5 then the actuator extends and likewise if <5V it retracts.  Since the DAC can output +/-10V the motor can retract faster than it can extend (extension speed is much less than the rated velocity; 0.4 mm/sec versus 1.5 mm/sec).  This is very odd as the actuator is rated to go the same speed in both directions, and in fact it does on a completely different controller (Newport ESP300).
    So, I have been in contact with Physik Instrument as I don't understand the issue.  Their response at this point is:
    "At the input of the C-809 it expects 0V for stand still, +10 V for
    maximum positive velocity and -10 V for maximum negative speed. The
    customer has to achieve this at the output of his DAC. If the customer
    doesn't achieve this voltage levels he has a problem inside of his
    software and not a problem of our hardware."
    Based on the output from 1-D interactive and the Read DAC.vi there is clearly a discrepancy.  Is it possible that the PCI-7352 is really operating around 0 as the zero velocity point, when 1-D and Read DAC seem to indicate otherwise?
    At this point it appears as though I'm going to have to manually see what the DAC is outputting, but without a breakout box I'm afraid I'm going to have to purchase a cable as a donor to slice and dice.
    Thanks for any help.
    -Derek

    Derek,
    that's strange behavior. In a closed loop system the controller's output value is defined by the characteristics of the plant. The Read DAC vi returns only the value that is sent to the DAC, but it doesn't measure the real voltage output. One chance is that there is something wrong with the DAC. E. g. I could think of an extremely high offset of -5 V or something like that. Here is an idea how to get a better understanding what's going on:
    Disconnect the C809 from the 7352.
    Configure the board for open loop stepper operation. This will unmap the DAC from the axis.
    Use Load DAC.vi to write a value directly to the DAC.
    Measure the voltage at the analog output. Depending on the cable that you are using, this might be a little bit tricky. If you can't do the measurement directly at the cable, you could ask your local NI branch if they could loan you an UMI-7764 and an SH68-C68-S cable.
    Please let me know how things are going. As the drive and the motor work fine with another controller, I don't think that the C809 has a problem. Stil I have good contacts to PI, so I could talk to them if required. 
    Another question: Have you tried the second axis on the 7352? Do you see the same issue with this axis?
    Thanks and kind regards,

  • Connect to Oracle using DAC Client in command line

    Hi,
    I'm trying to connect to Oracle DB using DAC client. I have configured a connection and tested, it works. When I use the connection to connect to the DB, its giving me an error
    "unknown error, please start in command line mode and see the stack error"
    How do I start in command line mode? Could anyone provide more information on this.
    Thanks in advance,
    RK

    In oracle db, you can create 3 different types of users:
    (1) create user x identified by pwd.
    In this case the user x will connect to the db using username/password, in this example x/pwd
    (2)create user ex identified externally;
    In this case the user ex will connect to the db using "/" and the sqlnet.authentication_services parameter value in the client and server sqlnet.ora will be used in determining the oracle external authentication adapter to use. For oracle windows client/db server, this is by default set to NTS. NTS is the oracle windows authentication adapter.
    (3)create user gx identified globally as 'CN=gx,O=Oracle';
    In this case also the user gx will connect to the db using "/" and oracle ssl will be used to authenticate this user to the db.
    It would not be possible to "Create user x identified externally" and connect with x/pwd.
    Please clarify.
    To help you in isolating the problem, I will need the following info:
    (1)
    what are you connecting as to execute your plsql. Are you using sqlplus ? How are you connecting (connect "/ as sysdba", connect "/", connect x/pwd) ?
    (2)
    what create user statement did you use to create the user
    (3)
    is odp.net and the db server on the same machine.
    (4)
    did you run your plsql from the same machine as the db server.
    (5)
    if odp.net is on a different machine than db server, did you try connecting from odp.net machine to db server, using sqlplus ?

    Please suggest if there is a way to run .bat files using DAC ? I suppose it can be done by configuring Execution Type as External Program. Please suggest how can this be achieved.
    Thanks

    I performed the same steps given in the link and ran the ex plan, but the task shows running and never completes. In my case i have created bat file for a different purpose (not for purging cache).
    Is the path shown in Step 5 the default path or it can be any path ? Please suggest.

  • Using DAC for custom Environment

    Hi All,
    I would like to know that, can we use DAC to schedule , run the loads for custom ETL environment(not BI APPS), does DACt supports. Below is is my set up
    -Oracle 11g DB(source and target )
    -Informatica 9 installed
    -Mappings, workflows are developed
    -DAC 11g is installed
    Now I want to set up DAC so that I can run loads from DAC instead of Informatica. Please any let me know high level steps. Is it different from BI APPS environmen if so kindly let me know configuration
    Thanks in advance

    Short answer is NO...as per licensing agreements, you can only use DAC and OBIA to load a OBIA DW target.
    pls mark correct

  • Verifying the Output of a DAC IC

    I created this VI to test DAC IC's using some open source code from Aardvark. I'm using labview to test and qualify DAC IC's over a range of temperature, so I made this VI to test four 8 bit DAC IC's sequential order starting with Address 0xC, during this time the for loop increment's the output cmd address from 0 to 255 (Hex) so that I can test every bit of the DAC. Each bit enabled should create a 19.5mV increase until it reaches 5V. The output graph looks like stair steps (see attachment). Now that I have all that working, I would like to somehow track the errors if a bit did not increment to the next bit value. How can I do this? I would also like to add show the bit setting on the x-axis so that the graph represent the data correctly, y-axis = volts and x-axis = bit setting.

    Do a search for "DAC Linearity".  DACs are generally qualified by their INL and DNL values.  NI has some sample libraries available to do the analysis.
    http://www.ni.com/white-paper/5366/en  --  Overview
    http://zone.ni.com/devzone/cda/epd/p/id/4477  --  Old example code for testing Video DACs
    That should get you started.

  • Regarding REFRESHING of Data in Data warehouse using DAC Incremental approa

    My client is planning to move from Discoverer to OBIA but before that we need some answers.
    1) My client needs the data to be refreshed every hour (incremental load using DAC) because they are using lot of real time data.
    We don't have much updated data( e.g 10 invoices in an hour + some other). How much time it usually takes to refresh those tables in Data wareshouse using DAC?
    2) While the table is getting refreshed can we use that table to generate a report? If yes, what is the state of data? Stale or incorrect(undefined)?
    3) How does refresh of Fin analytics work? Is it one module at a time or it treats all 3 modules (GL, AR and AP) as a single unit of refresh?
    I would really appreciate if I can get an answer for all the questions.
    Thank You,

    Here you go for answers:
    1) Shouldn't be much problem for a such small amt of data. All depends on ur execution plan in DAC which can always be created as new and can be customized to load data for only those tables...(Star Schema) ---- Approx 15-20 mins as it does so many things apart from loading table.
    2) Report in OBIEE will give previous data as I believe Cache will be (Shud be) turned on. You will get the new data in reports after the refresh is complete and cache is cleared using various methods ( Event Polling preferred)
    3) Again for Fin Analytics or any other module, you will have OOTB plans. But you can create ur new plans and execute. GL, AR, AP are also provided seperate..
    Hope this answers your question...You will get to know more which going through Oracle docs...particular for DAC

    I am working on a similar format for a report and if possible can you please give me some guidelines. I have initially created reports using XML Publisher, but for those , the output preview format was PDF. So, if I select the preview format as EXCEL will it give me output in Excel and for this to happen, how do I define the rtf template. I believe the working will be same as for PDF, create a rdf report, get output in XML and apply the template to get the data in Excel or there is something different to this.
    Thanks,
    Sunil
