Can I multiplex data inputs direct-DAQ PXI and SCXI?

Hello

In a PXI chassis - SCXI - combo PXI1052 (PXI-6602/6052E/SCXI1112/1125, LabVIEW 7), I know how to read the different SCXI Modules in multiplexed by DAQboard controller mode

e.g. SCXI module 1 - module 2 SCXI data - SCXI module 3 data - data of the module 1 SCXI module-...

However, I would like to use the direct entries in DAQ cards as well. for example

PXI MIO grabs - SCXI module 1 data - module 2 module SCXI - SCXI module 3 - inputs PXI MIO - SCXI module 1 data-...

I couldn't find a solution in the documentation or discussion. Thus, this task can be a) impossible or b) trivial. The obvious solution to use 2 different PXI-MIOs is only as a last resort.

Thanks for your help.

Hi Michael,

You can add HAVE strings of the MIO to the same task DAQmx SCXI modules. If you use the DAQ Assistant, hold down the ctrl or shift during the selection of channels to select channels from multiple devices, or click the '+' to add more channels to a task existing DAQ Assistant. If you use the DAQmx API directly, go ' PXI1Slot4 / ai0:15, SC1Mod1 / ai0:7, SC1Mod2 / ai0:7 "(or something similar) in the DAQmx setting create channel physical channels. You can also call DAQmx create channel several times with the same task handle, which is useful when multiple channels must measure different types or channels of communication.

  • Can you stereo audio input in an iPhone and listen in real-time?

    Well, it's rather a strange question, so I will explain briefly the background... I am a user of the hearing and I'm considering the purchase of hearing aids new fantasies that are capable of connecting to an iPhone (wireless via THE Bluetooth); This allows several things, including the ability to listen to the audio from the phone.

    I currently don't own an iPhone but wonder if buying one, as well as these hearing aids (Starkey Halo 2, if you're curious) might be a good option.

    The thing that is currently my attention is: is there a way that I could use this configuration of audio stream of (for example), a TV or a stereo directly to hearing aids? To do this I would need power audio * in * the iPhone and do share the same audio output for hearing aids. The audio input should be high enough quality and (especially!) in stereo, not mono; so we couldn't use the 3.5 mm jack. Ideally, I'd like to audio input via a digital SPDIF (PCM stereo) connection; If this is not possible then via a signal analog stereo level line (preferably via XLR, but failing that would make a jack or RCA). Another important thing is that (except what is inevitable due to the nature of the Bluetooth connection), this should be pretty low latency.

    I guess I would need some kind of accessory for this and perhaps also additional software.

    How possible it seems?

    You might want to repost on in the forum "hearing". There seems to be a number of users of Halo.

  • The differences in code main PXI and SCXI

    The similarity is code written for a target SCXI and PXI? Is it reasonable to say that if you are comfortable PXI targeting devices, that knowledge is transferable to SCXI. We are planning to move to this platform and I was wondering that maybe the inpact on my code.

    Secondly, PXI is newer than the SCXI? It seems to me that you can do most of the things SCXI on a PXI system. I must be wrong about this, otherwise why would there be combined chassis?

    much thanks in advance

    The big difference is that the channel names naming conventions are different because SCXI adds another level of multiplexing for your i/o devices.

    Yes PXI is newer than the SCXI.

    PXI is a hardened verson of the PCI which the standard bus, you will find in PC towers. With the right interface, you can do DMA and no matter what else supported by the PCI bus.

    SCXI is a bus structure that allows the addressing of points of e/s and their routing to an A/D converter. For centuries, this A/D converter has been on a devices PCI or PXI (which also has the logic of selection SCXI contrlled) but recently the A/D converter and the control logic were placed a device USB PCI or PXI are not required in all cases SCXI longer.

  • Inputs voltage DAQ affecting each other and the camera, they save you of

    Hello world!

    I use ELVIS II + and LabVIEW 2012 to register a device with a resistive sensor voltage (voltage see with ELVIS II.jpg for VI). The device (device + ELVIS II Schematic.jpg) measure the voltage across the resistive sensor and is controlled by a msp430. If the msp430 believes the change of voltage of the probe is above the threshold, a light is on. There is a motor function on the device and the LED is normally not on when the engine is turned on. I found that registration with the acquisition of data affects the behavior of the device. The reasons daq hardware and devices are connected. During data acquisition does NOT record, gross and analog sensor in tensions are constant (and the LED off) while the engine is on (Figures.doc; (A). when data acquisition IS recording, the engine power seems to distort analog in / raw voltage of the sensor causing the LED lights up (Figures.doc; (B).

    The trials that did not issue (led on while engine):

    1. registering with new ELVIS II + DAQ

    2 separate inputs raw and engine sensor on data acquisition

    The tests which fixed the problem (any engine LED is off):

    1 grounding gross and/or motor sensor

    2 separate channels of raw and engine sensor in the wizard DAQ (Figures.doc; C: shows engine and raw sensor separated by A_VCC. Figures.doc; D: where engine and gross sensor are side by side). I don't know why the order of the channels in the DAQ assistant would affect the behavior of the sensor signal.

    Any advice on this problem and ways to troubleshoot/potential long-term solutions would be greatly appreciated!

    Thank you!

    If your device has no acquisition of simulteanous, then each channel is multiplexed in the ADC. It has a capacity of entry inside your device, which gives it a 'memory '. If the voltage stored in the capacitor is not unloaded a scan before the next scan starts, then the second scan will "remember" is the result of the first analysis, give you really weird problems. More source impedance on the canal e e greater probability that the signal from the previous 'remembered '. That's why the order of the questions, the higher source impedance going first.

  • Would it not correct to say that the PCI-6110 can be set to 'redeclenchables' but the PXI-6115 module cannot use this property?

    Would it not correct to say that the PCI-6110 can be set to 'redeclenchables' but the PXI-6115 module cannot use this property?  If Yes, where is it documented the series cards can do trigger?  For example, is it possible to configure the trigger on the PXI-6124?

    Hi Joel_Neptune,

    The PCI-6110 and other materials as the PXI-6115 S series and SMU-6124 do not natively support NOR-DAQmx analog input alarm. However, you can use one of the generalist counters/timers of the Council to generate a reenclenchees pulse train, then use this as the sample clock pulse train. This transportation example shows how:

    LabVIEW\examples\DAQmx\Synchronization\Multi-Function.llb\Multi-Function-Ctr Retrigg Pulse Train generation for the Clock.vi sample

    In addition, the new material of the simultaneous sampling X series are supported trigger analog input without using a separate task of counters/timers.

  • Windows XP does not start. Can I boot Windows from a disk so that I can recover the data?

    Windows XP does not start. Can I boot Windows from a disk so that I can recover the data? This should be a CD because it doesn't have a floppy disk on my laptop drive. It is maybe that my hard drive has begun to fail and therefore cannot locate XP startup files. I can not start using one of the other methods of starting for example. Safe mode. If I can recover the data, I can then reload Windows and check the surface of the disc etc etc. Thank you all for your comments. Steve

    Lately, I'm leaning toward the Hiren's BootCD you can download here:

    http://www.hirensbootcd.NET/

    On the left, click on download, scroll down, choose the most recent version

    The download link is a little hard to see.  It is at the bottom of the page, above the drop for older versions and looks like this (click this component to download the ZIP file):

    Direct HTTP mirror + Torrent, Torrent Magnet

    Click the "Live HTTP Mirror" link to start the download and save the ZIP file on your desktop of somewhere that you can remember.

    The ZIP file is large, so the download will take probably some time to complete.  Then unzip the download to extract theHirens.BootCD.ISO file that will be used to create your new bootable CD.

    Create a bootable CD. ISO file is not the same as simply copying the. File ISO onto a blank CD.  You must use software that includes how to burn a. ISO to a CD to create a bootable CD.

    File ZIP the Hiren is the file BurnToCD.cmd that you can double-click to launch it.  The BurnToCD.cmd will use the file BurnCDCC.exe to burn the. ISO file onto a blank CD using your existing CD burner.  You can also use your own burning software as long as your software is able to create a bootable CD. ISO file.  More modern burning programs can create a bootable CD. ISO image.  Create a CD from an ISO image bootable is not the same as just the file on a CD burning.

    If you need a simple and CD burning, this is a free software popular software:

    Here are some instructions for ImgBurn:

    It would be a good idea to test your new bootable CD on a computer running.

    You may need to adjust the computer BIOS settings to use the CD-ROM drive as the first device to boot instead of the hard drive.
    These adjustments are made before Windows tries to load.  If you miss it, you will need to restart the system again.

    When starting on the Hiren's CD, you will see a menu of options.  Choose Mini XP.

    It will appear while Windows is loading and you will be presented with a desktop computer that has the look and feel of the interface of Windows Explorer, you are already accustomed to using.  You will feel at home.

    Using the Mini XP, you can access the Internet, maneuver around your system, copy files, replace the files, run the scans for malware, etc.  There are dozens of free and useful tools included in the CD that can be used to repair your system, or copy files to another device such as a USB device or an external drive if drop in trying to repair your system.

    If you want to see if you can fix your system, describe what is happening when you try to start and to answer these questions:

    What is your system brand and model?

    What is your Version of XP and the Service Pack?

    Describe your current antivirus and software anti malware situation: McAfee, Norton, Spybot, AVG, Avira!, Defender, ZoneAlarm, PC Tools, MSE, Comodo, etc..

    You have a true bootable XP installation CD (it is not the same as any recovery CD provided with your system)?

    If I put in place an openfiler VM as a data store iSCSI & vmfs on two ESXi hosts, both ESXi hosts can access two data warehouses?

    The reason why I ask, is that I have two hosts ESXi ESXi 4 running.  I do my backups with ghettoVCB, which I modified to create thin backups on one of the drives the.  I then wput them to the server, which causes them to become thick.  Directly targets the backup in a vmfs iSCSI on the server in the face shop.  It would save a step and the vmdk backup should remain thin.

    The short answer is Yes. If you allow the ESX servers to see the LUN. This setting is configured to the Openfiler.
