The iMac has a digital input?

• Digital inputs only noisy when the laptop is plugged

  I had problems with loops of Earth and power supplies for laptop in the past.  But it is the first time I got it so wrong that it makes the digital inputs which are both related to the ground and the debounced software cannot be used.

  It is NOT material OR.  It's a DT9816 of data translation, a USB DAQ Multifunction with small budget.   The laptop with the problem is a refurbished Dell, with a very obvious not Dell PSU who throws to the top of the warning in the BIOS and scales back from the processor.  (Danger Will Robinson!)

  The problem with the digital entries shows only upward on the Dell when it is plugged into a power outlet.  On all other machines and with the printer unplugged Dell, digital inputs floating.  But those that I have attached to the Earth is rock solid and work very well.

  What surprises me is more than the noise is so bad that even tied to the ground with a half second debounce, I get always false triggers.  I have not brought to power, but considering that it sounds really loud, I suspect that it looks pretty bad.

  I think I'll try a powered USB hub.  If this does not work, then I think that the customer will have to replace the power supply on the laptop.

  However, I was surprised.  I used a lot of USB DAQ hardware, and it's the first time I've never seen a problem like this.  The NI USB 6002 I tested on this same laptop does not seem to show the same problems.  Even if it is true that this is a different software and the test was brief.

  I'm curious to know if other developers have found something similar in the past.

  I can confirm that using a USB hub external powered eliminated the problem of noise in the original post.

  Interesting things.  I had not seen this before.  Now, I wish I had again the NI DAQ USB I had here last week so I could test that.

  Looks like I'll use a hub powered on this project.  But I think I will recommend always replace this power.  Although a lot of noise coming from the power supply, probably isn't good for nothing plugged it... or even sitting near him.

• Digital input to Toshiba 46TL-> no analog audio output to amplifier

  Hi all

  When I connect a video source (e.g. computer laptop via DLNA) to my 46TL, output TV audio analog (red/white taken connected to an amplifier) does not work.

  It does, however, watching television.

  Is it possible to configure the TV to read the audio data from digital input (HDMI/DLNA) to the analog output?

  Thank you for the help

  Not quite what series of TLxxx you have, but for example the TL938 supports a digital (optical) audio output port that provides a digital audio signal.
  Why n t connect the amplifier to the TV using this Jack?

  Connectors for component video / audio to the rear of the TV are the ports of ENTRY and not the OUTPUT ports. So, you can send an audio signal to the TV and not the amplifier output.

• The firewall on the iMac should be turned ON or OFF?

• You can synchronize digital input with an analog input on a 6034e?

  Is there a way to synchronize the digital input and analog input on a 6043e?

  I tried the test application "SyncAI_ReadDigChan", but it fails during the humor tick Verify():

  "The requested value is not supported for this property value.

  Property: NationalInstruments.DAQmx.Timing.SampleTimingType

  You asked: NationalInstruments.DAQmx.SampleTimingType.SampleClock

  "You can select: NationalInstruments.DAQmx.SampleTimingType.OnDemand.

  I'm currently collecting analog input data for the duration of a digital input pulse.

  Thanks for any help.

  No, you can't.

  The problem with E-Series cards, is that they have just static DIOs, so you cannot have their clock.

  You would need a M-series card for that where you have correlated DIOs.

• With the help of digital input for Boolean control?

  Hello!

  I have spent a lot of time to search but have not found a solution to this...

  I have LV 2015 with chassis NI 9188 and module NI 9425 DI.  Try to use the input signal to assign a State structure machine program and/or events in real time.  It would be acceptable to have an indicator show the status of the input line, since I can use it elsewhere with Value (Signaling).

  Please do not ask for the code - the problem is quite simple.  I just want to use the digital inputs to program control as a T/F.  I want just the program to analyze the State of the input and decisions - a bit like a PLC.

  All I seem to be able to extract is data of digital waveforms with a task DAQmx.

  It's not a trigger - I already use a trigger to start the analog acquisition.

  Formulate the problem in a simpler way...  What to do if you had a digital input module and you wanted to see the status of each input line in the form of a LED on your face in real time.  How would you do it?

  I really appreciate the help!

  I would like to write what has been read to the Terminal.

  From what I can tell, you want to just read a single static value from your digital line.  You can then simply read the value of one and do some logic with her.

• PCI-MIO-16-1 shows the digital inputs 1-7 on, without same cable connected

  Max, my PCI-MIO-16-1 shows the digital inputs 1-7 as having entries of tension without same cable connected to the Board. No amount of spin with her (to the MAX) seems so he can act correctly in input or output mode. It's true, there are voltages on these pins. If I connect my cable (to a TBX-68 block), I see that it has on $line0 (on port0) 0v, 5v on line7 and 2, 5V on the rest. Trying to put these lines to something else in MAX seems to do nothing. (I also can't control the OD, either.)

  This card has tried to get a couple of have Weiwei at high speed. Now that I'm branching out, I found a strange behaviour. Of course, I tried to restart and turn off the computer and turn it back on. Automatic test MAX Returns instantly with a message "transmitted", that gives me hope, even if I don't trust the speed at which it seems to perform the check.

  I'm a complete noob at this stuff. Is there something obvious that I might be dominant? Is there a way I can test more deeply that the card works as it should?

  The open connections to the TTL inputs are usually detected as logic 1. You are not testing properly. Connect an entry to two gnd or + 5V. Don't let them ever floating.

• the value of the digital inputs to change the field

  Hi all

  I have an edit field that has a digital text filter that only accepts phone numbers. Users have the choice to load these numbers from address book or direct entry.

  I used the digital filter to allow only numbers. .

  But when I tried to load these address book.  with editField.setText (phoneNum); It is to throw IllegalArgumentException.

  How to set digital inputs to the editField?

  Hi thanks for all your entries!

  My issued are resolved. I used BasicEditField aulieude EditField to solve this problem. the basicedit field allows the digital text and it solved the problem.

  Thanks for all your interest...

• My new provider password has 10 digits, but TB only accepts 8. If I can't get the full password.

  My employer moved to a new provider email accounts and I got a new password consisting of 10 digits. The computer of the company uses Outlook and there is no problems. But they also want to get my emails on my computer private, where I use Thunderbird. And TB does not accept the last two digits of the new password. What can I do?

  @Matt: it took me a while to find the check box "Show passwords", because in my version, it's hidden in "edit - preferences - security - passwords - passwords saved. But finally, I arrived and saw that even the old password of the old provider has been stored. And who had indeed exactly 8 digits. So I clicked on 'remove' and deleted the old password, thinking that this might be the reason for tuberculosis to accept only 8 digits. But, @Zenos: then I tried again to "get the job", has requested a new password and had the same problem as before. Entry stops after 8 characters.

  @Both: thank you, however!

  Edit: So I've completely closed TB and opened once again, while he tried to get my emails automatically. And even once asked me for the password, and this time he accepted all 10 characters! Problem solved!

  Thanks again to you both!

• My iMac has been slain on the wheel that turns for hours after I entered my Apple ID in the Setup

  My iMac has been slain on the wheel for hours after I entered my Apple ID in the installation program do I do?

  Hold the power button until the screen goes black.

  Wait at least 10 seconds, then press power once to turn back on.

  If you still have problems, boot in Safe Mode boot Safe Mode.A removes the system caches that can help.

  Upper left corner of your screen, click on the Apple  > Shut Down.

  After your Mac stops, wait 10 seconds, then press the power button.

  As soon as you hear the startup tone, hold down the SHIFT key. You must press the SHIFT key as soon as possible once you hear the startup tone, but not before.

  Release the SHIFT key when you see the gray Apple logo and progress indicator.

  Once you are in Mode without failure, return to the menu Apple . In the drop-down list, click: reboot

  On Safe Mode

• Unable to connect to websites using safari, although my wife use the imac, which has a separate login id can?

  When I open Safari from the dock it shows as usual, but when I try to connect to it looking for Web sites, it does not. can't display preferences etc either. Also, my wife uses the Imac and has a separate login ID and its works very well for her. Worked ok until the end of the week. Any ideas how to fix? Have tried to install the latest version of Mac OS X, but nothing helps.

  What version of Mac OS X is installed, your profile shows 10.7 but I suspect that it is not correct.

• Read the digital input, update display counter, email me info counter file

  Hello guys,.

  I would like to create a CVI program to read a digital line connected to an external switch. View the number of times that the switch has been pressed and save the data to a csv file. I'm eble to create some tasks of DAQmax project and I also created a text box (do not know if I have to use a textbox) to display the number of times is based on the switch. I just can't understand how to write update the text box, or save to a file. Any help will be greatly appreciated.

  -Rookie CVI.

  Have you tried the example program? This will show you the necessary elements which must be added to the project. In particular, you will not find any item in the menu Instrument linked to the Commission and no component in the project tree (well, actually samples use NOR DAQmx IO control instrument, but it's just to populate the controls in the UI for demonstration purposes, normally programs do not have need of these components to work).

• Reduce the period of sampling of the digital inputs of NOR-USB-6009

  Hello

  I need to read a line of digital input in the NI USB-6009 using NOR Express 2013 Signal box. I selected 1 sample (upon request) as acquisition mode. I need to define a smaller sampling period as 1 MS, but it gives error too short sampling period: "the current sampling period is too short.  Please specify a longer sampling period. ».
  I do not understand the reason for it and a way to slove this.

  Any help would be greatly appreciated!

  Thank you!!

  The 6009 doesn't have a clock that you can set for a sampling period. According to the specifications, the digital I/o is software programmed - sample on request you use now. I'm not at all familiar with SignalExpress but I don't think that you can find near a reliable khz sampling frequency on Windows or any other os non-deterministic.

• simultaneous monitoring of the digital input lines when executing digital writing tasks

  I'm writing a multithreaded application in C on Windows 7, using the 9.6 DAQmx API and device USB-6509. This requires that we constantly monitor several lines on the 6509 for entry, digital using the change of the device detection feature. You must also write the digital output without having to stop monitoring the input rows. It is very important that the input rows be monitored continuously for the duration of the project.

  In the DAQmx manual reading, it seems that it is impossible to make a digital reading as well as a digital writing occurs, even if these tasks are performed in different threads. (The same I understand, that it is impossible to have several tasks of digital entry running simultaneously.)

  It seems that it would be possible to launch the task for reading (configured with the change detection), to pause playback, start the writing task, pause the task of writing, and then re - start the task of reading. But - and this is the important part - for the duration of the writing task is running, is it possible to configure it to the task of reading will always monitor the lines, even if it's just stores the data in the buffer for these periods? The key is that the data will be lost.

  Thank you

  Each channel is independent. If you can get the input data that you export a value. You need not make a break each task. The two tasks are parallel.
