• The interface usb audio of Behringer U-Phoria UMC404HD work with Garageband?

  I just got an interface USB 4 channels for recording guitars and microphones. It has no driver, but instead uses the Mac OS. I implemented the sound control panel to recognize the device input and output, can I use the Audio configuration utility and MIDI to fit a recording at 192000HZ.

  My problem is that as soon as I open GarageBand 192000HZ setting falls down to it is more low 44100 HZ. It is a flaw with the audio interface Behringer or is it a problem of system software?

  I will mix Behringer messages on this problem, a guy says that the interface has a bad component castigates other Garageband.

  I would appreciate hearing from anyone with any interface from Behringer, who used it to 192000HZ using Garageband.  Any other comments welcome.

  

  

  I have this problem on 3 different computers using systems to a new installation of 10.11 10.6.8. A few different USB cables. More recently, on an I7 Mini with memory 16 concerts with 10.11.6. Currently on Garageband 10, but the same problem with Garageband 6

  I talked to an Apple technician and the answer is that Apple has "capped" sampling in 441000HZ setting.

  Thus, in spite of the box is designed to accept 192000Hz sampling, apparently GarageBand has been paralyzed for a lower sampling only to the adjustment system. Another program audio I, Amadeus Pro, has no difficulty with the parameter to 192000.

  TSK, tsk Apple...

• Timed signal generation TTL with the NI USB-6501 to be read by Arduino Uno

  First of all, I want to apologize - I am very, very new to LabVIEW and brand new to the development of the software of control equipment in general. I tried to find an answer to this question already, but I'm not entirely sure what I'm looking for.

  I have currently a work program LabVIEW which operates a gun card NI USB-6501. Due to the nature of having a machine that springs from a powerful beam of electrons, we want to assure you that if the computer controlling stalls or fails for any reason, we have built-in security that can stop the gun. Our current idea is to connect an Arduino Uno on a PIN on the USB-6501 and LabVIEW to generate a timed signal, which may read the Arduino. If the signal fails (indicating that the control computer has queued or off), the Arduino triggers a power relay that is independent of the control computer and turns off the gun.

  I understand that the USB-6501 operates on TTL signals, so the signal that I should be something in the sense of "output TTL high, wait 1 second, output low expectations, a second, repeat TTL ', but I have no idea how to go about programming in LabVIEW. My first thought was that it is a square wave by using the function "simulate the signal" output, or to have trigger an iterative Boolean signal, by using the function 'DAQmx write', but I don't really understand how do to implement or another idea, or if an idea would even work.

  Any advice would be greatly appreciated.

  Hi Elizabeth,.

  THINK THE STREAM!

  When do you DATAFLOW think everything falls in places!

  Several problems:

  -You have to put that MAKE impulse VI in his own loop parallel to your main VI!

  -When you place this generation of impulses in the effects loop ("TTL arduino low-high") you should put the CreateTask and StopTask outside the loop: no need to create/stop the task in each iteration.

  -Why are there points of constraint to waiting functions?

  -Why is there bent wires? You know Ctrl-U?

  -LabVIEW comes with an extensive library of example screws: you looked at all these examples DAQmx?

  -Suggestion: Learn more about the "structures of producer-consumer"!

• Equium A60 issue of the wireless USB mouse

  I bought 3 optical mouse for my equium A60. The first 2 have worked for a short period, but then appeared to be very erratic, beating on the entire screen and the slightest touch. I just bought a third and spend money on it to combat this problem, but it's always like it. It's a belkin wireless optical mouse. The connection is USB and I have no driver to install. It flies just all over the screen completely uncontrollable. Please can someone help.

  Hello

  Have you checked the pointer options in the properties of the mouse?
  In my opinion, you should try changing the query options to slow down the pointer options.
  In addition, improve it the accuracy of the pointer must be marked.

  Good bye

• Simulator of 9550 with the issue of the interface user of Eclipse

  When I use the 9550 Simulator provided with eclipse UI simulators for the 9550 wrapper (which makes the phone looks like a phone) disappeared. It's just white. I can click on the harware buttons and they respond very well. It's really strange. Is there a work around? And no I'm not set in single mode LCD. Other emulators provided with the Eclipse plugin like the 9700 do not have the same question.

• NI USB-6501 digital output problem

  Hello

  I use DASYLab v.11 and I'm working on an interface with the NI USB-6501 where I'm putting a digital high on four ports.

  With the module "NOR-DAQmx - digital input", I managed to read the digital inputs of the ' NI USB-6501 ".»

  It's only the "NOR-DAQmx - digital output" I can't go to work.

  Using 'NI MAX' of NOR I have easily can emmit my four LEDs in the way of my High/Low ports.

  But not with DASYLab. When you use DASYLab tension on the ports remains unchanged.

  Now, I have a switch module, generating 5/0, directly connected to the digital output module, which is assigned to my four output ports for my task.

  I also tried with a module of relay between the two without success. I also tried to use 1.5 above instead of 5 without success.

  I use the option 'Bus (0/5 supply) for the module "Digital output".

  "NI Max", I configured the ports as "active drive.

  Any suggestion of what I might be missing?

  Thank you

  Martin

  Hmm, four ports, or four lines?

  A port consists of eight lines. Each line can control an LED (ON / OFF ~ 0/5V).

  If you have created a task to dig-out to control a port, 5V to this port sending sets all lines of this port to 'high '.

  You need to 255 for each line one too high port (at the bit level: 128 + 64 + 32 + 16 + 8 + 4 + 2 + 1).<- eight="">

  Or, you can create a dig out tasks to control four lines of a specific port.

  Four lanes of the EEG DAQmx DigOut module.

  Each of the channels of the modul will feed a single line of the task/device.

  Four switches will then turn the lights, or turn off.

  Make sure, that the 'bitposition' is the number of correct line (see picture).

• Square of USB 6501 wave

  Hi all

  I would BE REALLY GRATEFUL if someone could help me with the following problem:

  I use the NI USB 6501 jury for an application of DIO. I would like to be able to output a form of wave digital about 1 or 2 Hz so that I can use it as INPUT for a door AND. The square waveform doesn't have to be perfect, as it is close to 1 to 2 Hz and the duty cycle is almost 50%, it's OKAY!

  The door AND has 2 entrances: the square wave is an and a Boolean control on the front panel will be a (i.e. the user can change at any time). FOR EXAMPLE, if the user sets the Boolean value of control on the façade to a '1' logic, the output of the gate AND must be identical to the other entry, which is the square wave. However, if the Boolean control is set to a logic "0", the output of the gate AND will be '0' all the time. I also want to display the 2 inputs and 1 output on a digital waveform graph based on time.

  The attached VI has connections already in loop (with everything tagged) with the exception of the graphic and square wave. THANK YOU IN ADVANCE!

  Try this simple example.

• Best way to generate the software clock for USB-6501 of Measurement Studio for c# VS2008

  Hi all

  I wonder if there is a better way to generate a clock software for USB-6501 of Measurement Studio for VS2008 in C Sharp?

  I have developed a clock using C Sharp "Thread.Sleep (msecPauseTime)"; and statements to switch digital output high and low. There are a few things I noticed in creating a software clock in this way:

  1. The smallest delay by the Thread.Sleep command time is 1 millisecond (which means higher clock period is 2 msec-500 Hz, not holding not ball account no. 2 below).
  2. Sometimes the delay I see on an oscilloscope is considerably longer than the delay that I specified in the sleep command.

  In my application, I create signals (a clock, a latch enable and data series) to control what an attenuator step through the USB-6501 RF connected to a USB 2.0 on my computer. This particular step RF attenuator can accept clocks with frequencies up to 10 MHz, so I would like to generate a software clock (without having to connect to an external clock to a line of input on the USB-6501) which is closest to this maximum frequency, and I think that the USB2.0 line could handle clock speeds over 500 Hz. Also, I would like to know why the delays that I see on the scope are sometimes longer than the time specified by the Thread.Sleep command. Is it caused by the suspension of the execution of my program processor for something else, as I suspect? Of course, this isn't a big deal, because it does not affect the time as my serial data and pieces change compared to my clock. However, I would like to know why it does this.

  I appreciate your help.

  Thank you

  Jonathan,

  Since the USB-6501 DIO is software programmed, you are at the mercy of the planning of the operating system and won't be able to work reliably with an external clock in the software.

  You can try to set the priority of your thread 'generation of clock' to improve performance, however, because Windows is not a deterministic operating system, there are still no guarantees.  Operating systems are not required to honor the priority of threads.  You can find examples and information on the definition of the priorities of the threads in c# here:

• Can not find the tourmalines usb gpib interface (agilent io suite) max

  Hello

  I try to use my USB-GPIB Interface of 63488 TAMS in LabView.

  There is a manual for the use of the TAMS Interfaces in LabView. You must uninstall all Suite of IO with the exception of the CLCL-pieces. The problem is, this option is not given in the new versions of the suite that run under win7 (14.2 +). And according to driver download site, you need to install Suite 14.2 +. It is misleading. On my request for a manual for the use of a newer version of the suite I don't got no answer so far, so I'll try on own and with your help, I hope.

  To do this, I have installed on my Win7 x 86 system:

  -LabView 2009

  NI-VISA 4.6

  OR-488. 2 2.73

  -Measurement & Automation Explorer 4.6.2

  -Agilent IO Suite 15.5

  -TAMS pilot 63488 v1.2

  The driver of the TAMS works on my system. The Agilent connection Expert I see the interface and the device connected. And I can connect through this connection.

  To use this interface in LabView, I activated the NI-VISA for Tulip passport, but I had no new device in MAX I tried to activate the Agilent GPIB cards for 488 programs in the Expert of the connection, but it was not the solution.

  So I checked the DLL. The GPIB - 32.dll is replaced by Agilent, so cards Agilent must be enabled for 488 programs. But the info for the t6348832.dll says "TULIP DLL for the USB/GPIB T63488". If the 488 option can take effect, but why I have no effect on the activation of the passport for a Tulip? Any ideas?

  Thank you for your help and support.

  Michael

  For someone who has this particular problem:

  I have found a small workaround to solve this problem. For this you need a Suite of Agilent, which will uninstall VISA without CLCL (review of Agilent IO libraries M.01.01 should be the last). With a tool like 7Zip, you can unzip the single installation file to get the installation files. Now you must enable the compatibility mode for Windows XP on the installation application before you install the libraries. After that, you can proceed as described by TAMS:

• NEITHER USB-6501 not recognized by the system

  Hi all

  I wrote this simple application that writes and reads a SPI frame.

  My PC have Labview 8.5.1 and DAQmx 8.7.1 (the CD was provided with my unit NI USB-6501). Everything works fine.

  But now I need to distribute the application, and I need to run it from a computer that does not have LabVIEW.

  I installed the latest versions of the runtime of LV (8.6), and the 8.7.1, DAQmx software but the program crashes produce an error (code 200477).

  I tried to install a more recent DAQmx software (8.9 full, engine of execution of 8,9 only), but the situation has not changed.

  Also: I tried on two different PCs, and I launched MAX: one of them doesn't even recognize that a DAQ hardware is installed (even if Windows recognizes as a work device).

  Anyway, the two PCs return error 200477.

  Any help will be much appreciated.

  Best regards

  Is - this dev4 on the pc without LabVIEW? You can easily see the device name in MAX.

• USB-6501 not seen by MAX

  Hi all!

  I have a PC under WHAT XP 2002 (SP3) with two USB-6501 Renault connected on it.  I can see two devices in the DEVICE MANAGER under the heading "Data Acquisition hardware" and the two seem to have installed proper drivers.  They show their driver versions of file as 2.3.1f0.  I also have NI MAX v4.6.2 installed on the computer.  But Max, I am unable to display all the devices.  When I try and expand the section "Devices and Interfaces", the MAX software enters a State of non-response and when he answers Finally, I get the following message redirect me to the Web site of EITHER:

  There was a problem connecting to the database.

  Restart your computer.  Refer to knowledge base article 42HG08DD for more information

  and if the problem persists, contact National Instruments.  Go to ni.com now?

  I could see the two Renault to the MAX on another computer with installed Windows7 and MAX version 14.

  Just make sure you install complete DAQmx with the support of the MAX configuration.  It is possible to enter in some States strange if you have MAX and DAQmx Runtime, but not the support of DAQmx for MAX.  In addition, MAX 4.6.2 is a real version, but very old.

  Note Setup below should work and will include a version of MAX.

• USB-6008, USB-6501 and Embarcadero C++

  Hello NEITHER and NOR users,.

  I spent a considerable amount of money several years ago on a number of devices USB-6008 and USB-6501 for a class that I teach on interfacing the simulations with realworld sensors and actuators.  Write us code using Embarcadero C ++ Builder and we wrote the code to interface with the jury of EZIO AD / DA via RS - 232.  The EZIO is much too slow and limited.  Given advertising NOR, we bought these boards, but after several attempts to get some information OR on the way to talk to these devices directly via C++, we have yet no valid response.  No, I don't want to LabView or any additional expenses.  I just want to talk to them directly.

  OR: are you ready to help with this, or not?  If this is not the case, although wanting to refund these purchases.  Announce as being accessible from C++, but you are not willing to provide any help of substance to this day...

  Yes, I am self-taught, write code, and old-school enough to feel that I have a right to know how to talk to all the devices I buy.  I confess my ignorance, but I'm sick and tired of secret corporate and misleading advertising.

  Can someone please provide me with enough example of code to start.  That's what we wrote for the EZIO:

  http://www.Duke.edu/Web/ISIS/Gessler/Borland/RealWorld-Ezio.htm

  We would like to start writing similar code for these materials of NEITHER.  If possible, we can buy more.  If this is not the case, these cards are useless.

  Kind regards

  Nick,

  When you have installed the DAQmx drivers to communicate with the 6008 and 6501, I assume you also installed programming examples? It is here that they are on my XP machine: C:\Documents and Settings\All Users\Documents\National Instruments\NI-DAQ\Examples\DAQmx ANSI C.  I don't think that Embarcadero C++ Builder is one of the languages supported, so you'll need to twist your compiler, but it should give you a good start.

• NI USB - 6501 OEM more sensitive to electromagnetic interference?

  We built a NI USB-6501 OEM card in a small instrument of office dedicated to switch ultrasonic impulses 300V between 3 transducers, using reed relays not shielded high-voltage controlled by the USB-6501 (using MOSFET transistors to drive the relay coils).  The end user reported that when he operated his ultrasonic transmitter at greater than 100 v voltages, USB-6501 would break (green "heartbeat" ceases, LabView or test panels lose communication with the interface).  Lower voltages to ultrasonic had no effect. Inspection of the 5vdc supply rails when running the pulse generator showed ears LOUD noise (surprise?), so we have recreated the box so that 1) optical isolation and no electrical connection between the USB-6501 and switching and 2) pension switching was surrounded by a 'box in the box '.   During a test, ultrasonic signals apparently still radiation enough so that the USB-6501 would break as before.

  Avoiding half measures, I mounted the USB-6501 in a completely separate extruded aluminum case (the land to the USB bus, but not to "taking" of land) with optical transmitters and optical fiber plastic 3' has been the only connection to the ultrasonic switch box (which is inside its own extruded aluminum case).

  This made things better: the USB-6501 would work for a while when the ultrasonic signals were present but still crashes after a few minutes.  In addition, reports researcher that starting the engine w / controller in immediate proximity to this interface also immediately causes a crash of the USB-6501.

  Right now I do more optical cables and confirmed that the USB-6501 works thankfully when he is simply the engine optical transmitters with no ultrasonic signals in the area.  I'm surprised that this digital i/o interface seems so sensitive to environmental disturbances.

  We made sure that 1) was based on the shield of the cable USB ONLY at the end of the PC, according to the specification USB;  2) cable USB was of ferrite chokes to make it less

  an antenna 'noise' 3 the Board 6501 had connected logic ground the housing in aluminium, and 4) we have equipped the case with a pattern important

  cable and clamp to connect to a 'true' of the Earth.

  When the end user has reported that there were still problems, I went to his lab and discovered

  He assumes that hang on a couple of wires ground wire, to a strain gauge, which was stuck on a piece of 3' of the railway, itself sitting on a wooden table

  no electricity whatsoever, what meant it was "founded".  After that I am makes me sputter and him look staring in disbelief, we plugged into an electrical conduit nearby,

  and all of a sudden, the problem disappeared.

  I'm glad it works now, but the fact that turn on an instrument of motor stepper located three feet of 6501 can crash against interference if)

  the case is not grounded), stillsurprises me.  I expect to use 6501 in other instruments, it will take extra precautions on the armor.
