How to disable SP-DIF (digital) output on Audigy

Hi, I am using Audigy 2 soundcard connected to Altec Lansing ADA885 speakers. These speakers have built-in Dolby Digital Decoder, and of course SPDIF input for this. Additionally, they have inputs for analog front and rear speakers signal. They can be switched to different operation modes : Dolby Digital decoding, Dolby ProLogic decoding, stereo, and quad modes. I have connected them to my Audigy 2 using analog connections, and also digital output. The problem is, that they process both kind of inputs (analog and digital) all the time in most modes simultaneously. For example, when I set them to "quad" mode (for gaming) they process analog signal that Audigy deli'vers them, but also they attempt to decode the signal from digital input. This produces some kind of phase distortions (basses dissappear and the sound becomes slightly muffled). Possible solutions could be : - disable digital decoding in speakers when using analog output from Audigy - this can't be done, these speakers' decoder is not configurable, - disconnect digital cable when using analog output from Audigy - obvious solution, however not very comfortable - disable "ON-DEMAND" spdif output on Audigy card and enable it when necessary. This would be most satisfying option for me. But.... is it possible at all ? Just something similar to the "Digital output only" setting in soundcard panel, but in my case i'd like to have an option of "Analog outputs only". Thanks in advance for any help Greetings, Martin

  • How do I keep a digital output from SCC DO01 from fluctuating states?

    Background: Hooking an ohm-meter across a digital output from a SCC DO01 isolated optical switch shows that the resistance fluctuates and at times goes open circuit. It appears directly related to the LabView code where I'm writing to this digital line within a WHILE loop. The loop has a variety of other operations going on. These other operations, I believe, are causing this problem due to timing or something.
    How can I improve the reliability of this digital output? There must be some method of establishing priority within a WHILE loop.
    Really appreciate the help.
    Hunter

    Howdy, Justin
    Thanks for your reply.
    I've actually been connecting the meter across Vss and Vout. Actuating the digital output, I can see the state of the switch. Attached is the VI which involves this DO01, specifically, it's associated with the VFD RUN/STOP.
    Since I sent this question out, I've actually gotten some help from Andy Watchorn of NI. This switch holds state much better.
    All the best,

  • How do I control a digital output on NI9144 FPGA with fpga code running on NI9082.

    Due to a recent change in our hardware configuration I need to locate my various I/O modules in various locations around the facility. I am attempting to use an etherCAT setup consisting of an NI9082 and multiple NI9144 (for now only one NI9144). I need both devices to run code in the respective FPGA and make the results available to the other devices and for user interface software. My question is is it possible for the two FPGA code segments to communicate directly with each other without going through the RT or computer interfaces. I need to fire a digital output bit on the NI9144 based on logic running on the NI9082.
    Are there any good code examples around that someone can point me to?
    Thanks for the help.

    Hi, you can include trigger conditions (digital, or analog) on your FPGA VI and connect directly the I/O from module to module (analog with analog & digital with digital), however, if the chassis are meant to be at different locations the cable used to connect the ports is equals the length in between each device and that could degrade the signal if we are taking about a couple meters or kilometers. The most reasonable way to send/receive data from great distances is through ethernet using a regular communication protocol (such as TCP/IP, network streams, network shared variables...etc).

  • How to I connect Sourcing digital output from My Interface Board to NI USB 6501 channel configured as Digital input

    When I connect an input to DI channel of USB 6501 card  from my board which has sourcing Output t, iIn the Off state it is not pulled down properly. The volatge on the port in is 2.1V -2.5V based on the pull down resistor on my board. I suspect that  it acts as a voltage divider.
    The state on the card is still show as "HIGH "state, even my sourcing output driver has a pull down  resister.  when I use this interface board for PCI mseries devices it works fine. Do the pull down resister on my sourcing output is not worth. Is this because of pull up resister 4.7k inside USB card 6501.
    USB 6501 specifications shows the Digital input accepts both source and sink modes. By default the card is in sourcing digital input mode. How do we can convert this in Sinkind digital input mode.
    Could anyone Please give your suggestions to overcome this issue .
    Thanks you.

    You really should not have both a pull up and pull down on the same line.  Really weird things can happen.  If you insist on having a pull down on your board, then I highly recommend putting a digital buffer chip between the DAQ and your board.
    Some boards with DIO have a pull up, while others have pull down.  You just have to watch the specs.

    You can only decellerate the speed: see CTR Pulse Config.vi (see hierarchy

  • Make USB-6001 digital output always high or low in C

    Hello all,
    I am new to the NI DAQ interface. I have an USB-6001 and I am trying to use this device to control some logic circuit in C. So what I want to do is:
    * set some digital output lines to high or low levels, and change their status when needed (in C).
    I have tested the device in NI MAX -> Test Panels, and found that the device is able to do this. Then I try to do it in C. I hace checked the examples, and the function I should use is the one called "DAQmxWriteDigitalU32". I have problem in understanding its input parameters. I have tried something with my own understanding, but it does not work as I expected. Here is one test I did:
    uInt32   data=1;
    int32 written;
    TaskHandle taskHandle=0;
    DAQmxErrChk (DAQmxCreateTask("",&taskHandle));
    DAQmxErrChk (DAQmxCreateDOChan(taskHandle,"Dev1/port0/line7","",DAQmx_Val_ChanForAllLines));
    DAQmxErrChk (DAQmxStartTask(taskHandle));
    DAQmxErrChk (DAQmxWriteDigitalU32(taskHandle,1,1,10.0,DAQmx_Val_GroupByChannel,&data,&written,NULL));
    taskHandle=0;
    DAQmxErrChk (DAQmxCreateTask("",&taskHandle));
    DAQmxErrChk (DAQmxCreateDOChan(taskHandle,"Dev1/port0/line0","",DAQmx_Val_ChanForAllLines));
    DAQmxErrChk (DAQmxStartTask(taskHandle));
    DAQmxErrChk (DAQmxWriteDigitalU32(taskHandle,1,1,10.0,DAQmx_Val_GroupByChannel,&data,&written,NULL));
    I want to simply set "Dev1/port0/line7" and "Dev1/port0/line0" to high level, but only "Dev1/port0/line0" responds me. The second parameter of the function DAQmxWriteDigitalU32 corresponds to numSampsPerChan. If i replace it (currently 1) with a larger value, e.g. 100, I can see that "Dev1/port0/line7" sends a number of 1 out, then return back to 0. So I guess the problem is just that I do not understand well all parameters of the function DAQmxWriteDigitalU32. Can anyone please tell me how I can set a digital output line to 1 or 0? 
    Thanks!

  • How to give delay in switch on digital output lines

    Hello All,
    I am working on PCI-6514 Digital IO card, I am writing a sequence to my application using DAQmax for  Digital input and output lines
    I want to switch on one output line0 and after a delay 5sec switch on line1 output and after a delay of 3sec switch on line2 output and sense input line 0 and line 1 .
    How can we know the status of output ie output is on or off.
    Since i am using the IO card for first time suggest me in this.

    Hi
    I am going to assume that you are using LabVIEW 7.1 for this application.  If you are trying to acquire data from an external device after outputting data to that device, the DAQmx tristate property node will give you this functionality.
    You will then need a DAQmx write.vi to output your digital data followed by a DAQmx channel property node. Select Digital Output>>Tristate on the property node and wire a true constant into it. After the property node, you can use a DAQmx read.vi to read the data coming into the digital lines. By using the tristate property node, you can avoid stopping the digital output task and starting an entirely new task.  I am attaching an example program that will demonstrate this.

    Hal L.

  • How do i create 6 digital 25Hz PWM output signals with my PCI-6221 card?

    Hi!
    I´m a student, who´s trynig to control a gasturbine process for my diploma thesis. The control program should be written in LabView 8. I need to control 6 25 Hz PWM signals for the gasvalves. The  needed accuracy of the duty cycle has to be about  0.1 %.
     A  tech. engeneer from  NI  told  us , that  we can  do this by using one single digital output for each PWM.
    Now, after a while, i need to implement it into my program. But there are troubles:
    My NI-PCI-6221 standard card only has 2 couteroutputs and only the first of the 3 ports seems to be buffered (Error Nr.  201062)...
    I tried to do the programming, by manipulating the "DIO_PWM_50Hz.vi" I found in google.
    Does anyone of you have any information or helpful examples how i can create these PWM with my card, or did I get a wrong Information by the salesagent (...not the first time....)?
    Thanks for your help
    Tobi

    Here you can find an example, how to do this:
    http://sine.ni.com/apps/we/niepd_web_display.display_epd4?p_guid=DE27921DB53A4D8DE034080020E74861&p_...
    As the text says, best would be to use the counter. As your Hardware has only 2 Counters, you would need additional hardware. Best would be to use a Counter-Card (660x), thes boards have up to 8 counters, so you coulkd control your 6 gasvalves indipendently.
    The soultion with the timed digital outputs of the m-series boards would only work, if you can use the same timing (one counter) for all 6 outputs.
    Hope this helps!

    Hi,
    the digital pattern generator (marching values) only shifts the binary value of the first signal and sample to the next signal/sample.
    Have you tried generating your waveforms via build waveform and use t0 terminal to change the lead delay?
    In general, this DAQmx example could be helpful which you can modify to your needs.

  • How to use Digital output to turn on sensor for Analog Input?

    I am trying to use a digital output to turn on an array of sensors that I then wish to read on 16 analog input lines. I have a 6024E DAQ card. I am planning to take data at 10-20 hz, so not terribly fast, but I will be acquiring for long periods of time (days) so I will be streaming data to disk.
    I have a fair bit of experience in Labview basics, but can quickly get out of my depth when I try something new (like this). I have V6.01.
    It looks as though the best way might be to do the DO and then a single AI as individual events, then write to disk and continue through the loop. I am puzzled, however, how to keep this cycle on schedule given that I don't know how long it will take to sample 16 channels
    , write the data to disk and get back to the starting point... perhaps this is so fast that I don't need to worry about it? The actual timing of the samples (be it 10 or 20 hz) isn't too critical, as long as I can record at what time they were taken... it would be frustrating to find that I was several seconds off after days of data.

    Hello,
    Thank you for contacting National Instruments.
    If you are worried about the time of your acquisition being off, then you should associate each voltage measurement with a timestamp. This will allow you to know the exact time at which the sample was taken and you will never be off. You can use the Get Date/Time in Seconds.vi in our while loop with your AI code so that you can read a sample and read the time. You can than log the voltage value and the timestamp to your file.

  • How to combine Digital Output, a delay and Analog Input in a fast loop

    I need to develop a process loop that runs at least at 250 Hz that performs a Digital output, than a delay of 50 microseconds and than an analog input of all the channels. All will be done using ATI MIO 64E3 card. Of course, the acquired data will be processed, displayed and saved. The loop will be running for several minutes until user stops it.

    The fastest and most precise timing will occur if you use hardware timing. You can apply hardware timing to analog input on the E Series boards, but not the digital lines. Let's focus on the analog input first. Continuous waveform scanning uses a scan clock, which can be the board's internal one or an external one which you apply. If you want to scan all the channels 50 microseconds after a digital rising edge, then you need an external signal to signify that scan clock.
    The E Series boards also have 2 counter/timers onboard that you can use for this purpose. You can set up a retriggerable pulse generation operation, where the counter receives a trigger and then on the user specifications, produces a pulse. You can have that route to the analog input scan clock.
    The trigger signal for the counter is that digital pulse. As I mentioned earlier, there is no hardware timing for the digital lines on an E Series board. We do have other digital boards (653x family) that have hardware timed operations if precision is important. If you are satisfied with software's resolution (in the milliseconds), then you can call the E Series board digital function in a loop with a software timer. That digital line can route to the counter to act as the trigger.
    So, on the programming side, you can have three separate and independent operations in parallel. One is for the digital function to output on that line every so often. Another is for the counter set at the retriggerable pulse generation. The last is for the analog input. I will describe this in terms of LabVIEW, but it can be done in a similar fashion with the NI-DAQ function calls or Measurement Studio.
    The digital examples are in the LabVIEW >> Examples >> Daq >> Digital >> E-Series directory. The Generate Retriggerable Pulse example is in the LabVIEW >> Examples >> Daq >> Counters >> DAQ-STC directory. The E Series boards use the DAQ-STC timing chip.
    Go to the LabVIEW >> Examples >> Daq >> anlogin >> strmdisk.llb directory and start with the Cont Acq to Spreadsheet File. This shows how to continuously acquire data and stream it to disk while displaying the data on a chart. Streaming to disk is the efficient way to save data while you are acquiring, as it eliminates the overhead of always opening and closing the file through the iterations of the loop. This saves to a file that can be opened by other applications (Excel, Word, etc.), but it is not as fast as writing to a binary file, which must be opened and read back through LabVIEW. However, for your ~250 Hz rate, it should be fine. Then, go to the LabVIEW >> Examples >> Daq >> anlogin >> anlogin.llb and look at the Acquire N Scans -ExtScanClk example. This shows how to apply the scan clock. Here, the AI Start that you saw in the previous example is replaced by 4 VIs (3 AI Clock Config's and the AI Control). Make those changes to the first example and then add a constant 0 to the AI Control parameter for total scans to acquire. That specifies the continuous operation. The File >> VI Properties >> Documentation menu item of the example describes the physical connections.
    If you aren't using LabVIEW, use the NI-DAQ User Manual and the NI-DAQ Help file installed on your machine. You can look at your AT E Series User Manual at the http://www.ni.com/manuals pages for more information on the hardware. Also, if you want to route those signals internally on the board, you can find some entries in the KnowledgeBase at the http://www.ni.com/support pages.

  • How to read back the output state for digital output or anlog output ?

    I use NI-pci 6221(68PIN) Accquistion card to do measurmet,after i do digital output ,or anlog output ,I find that the output will be maitained by the card.even after i exit my accquistion program.But if i reset the card ,the ouptut also will be reset.
    Now if i don't reset the card ,how can i read back the output state,?

    Hi Mike,
    There is no way for you to internally route an analog output to an analog input. The only solution is to physically connect the two lines together with a wire.
    I came to this conclusion through the following steps:
    1- Start MAX and select the DAQmx device under "Devices and Interfaces>>NI-DAQmx Devices" that you want to internally route signals through.
    2- Click on the "Device Routes" tab on the bottom of the right hand window (It defaults to the "Attributes" tab)
    3- Line up the Source with the Destination to see if the connection can be internally routed (either direct or indirect)
    I came to the above conclusion by following these steps for a PCI-6251 DAQ device (the analog output & input do not exist in the "Device Routes" tab therefore they do not support internal routing), but you should verify this for your specific hardware. Let me know if you have any other questions/concerns.

  • Help ! SBLive5.1 and QUAD CD-P - how to swith digital output to PC

    For the moment, my QUAD CD-P seem to be getting the signal but doesn't recognize it. I thought that maybe like a DVD, the digital output had to be switched to ''PCM'' instead of ''bitstream'' but I'm not even sure if the SBLi've 5. has that possibility or if I am mistaken altogether. I would greatly appreciate any hints regarding how this could be possible and with what kind of connections (cables)I would need.

    The Quad CD-P is a CD player wich acts as a pre-amp for the QUAD 99 series. This device only has digital and optical inputs No right or left inputs. No video inputs/outputs whatsoever.
    For the moment, it is now connected to a Quad 99 - Stereo Power Amp with the usual connectors (like the one for composite video, big RCA connectors, also called 'Digital inputs')
    I experienced some problems listening to the sound of my DVD until I found on the internet that I had to switch in my DVD menu the output from Bitstream to PCM. Afterwards, I had no problem listening to my DVD on the QUAD. Of course, with this configuration, out DTS but no problem with regular DolbyDigital. Quad being such a good (and expensi've) system, It doesn't matter that much. But the SBLi've seems to be a problem. As for my DVD, the QUAD pre-amp seems to be receiving the info from my PC but does not 'render' it. No sound is coming from my QUAD from the MP3s that are playing on my PC altough I tried to connecti it with a mini stereo-jack to digital (red and white) that fit on my sound card. Having had a similar problem with my DVD (quite basic actually), I thought that could be the same thing here. I tried several configuration playing with the 'sound and audio device' options from Windows XP's control panel but to no avail.
    I'm not even sure if it is possible to listen to music coming from my computer on this system. That is why I thought I would ask here 'cause I'm getting confused with something I know so little.
    Thanks.

    Are you seeing a red light at the port? It can get stuck so that it still thinks the headphones are plugged in. Try taking another headphone jack and plugging it in a few times.
