DAQmx Reset Device hangs

I have PXI-8110 controller with 10 PXI cards in them. When I try to reset these cards using "DAQMx Reset Device.vi", code hangs. There is no way to recover from this but to cycle power on the PXI controller.
Ofcourse, this happens rarely.
I'm using LabVIEW 2009, MAX 4.6.1f0

Hi Appu,
Do you receive any error message? Are you handling the errors with a Simple or General Error Handler? Can you manually reset the devices in MAX?

Delay after reset device?

I want to reset my device, including both modules and chassis if the device is a cDAQ chassis, and then proceed to setting the device up for aquisition. I find that if I do not include delays after the DAQmx Reset Device.vi, I get errors when I go on to setting up the channels and tasks. As shown in the attached vi, the delays work, but I think this is not a robust method. Is there a way to know, after a DAQmx Reset Device, when the device is again available for further interaction?
Thanks.

Reset Devices (SubVI).vi ‏22 KB

Hi Alejandro,
Here is my version of your suggestion. I used serial number rather than device type. Note that I want to reset all the devices in a chassis, plus the chassis itself, if the device is a chassis so I build an array with the module names followed by the Chassis name and then do the rest and wait for serial number operation on the array, one at a time.
When I use this immediately before a vi that does some moderately extensive DAQmx channel and task setup, the setup vi still fails. It gives the following message
Error -201003 occurred at DAQmx Create Channel (CI-Position-Angular Encoder).vi:4
Possible reason(s):
Device cannot be accessed. Possible causes:
Device is no longer present in the system.
Device is not powered.
Device is powered, but was temporarily without power.
Device is damaged.
Ensure the device is properly connected and powered. Turn the computer off and on again. If you suspect that the device is damaged, contact National Instruments at ni.com/support.
Device Specified: cDAQ2Mod1
Task Name: _unnamedTask<D7>
I am including snippets for both the Reset vi and the Is Device Chassis? vi. The is Device Chassis vi is one I worked out a long time ago by empirical experimentation. If you know of a better way to do that check I'd be glad to learn that too.

Resetting devices and counter states

How frequently should one make use of Reset Device? I have placed it at the start of a LabView program so that it runs every time this program is called. This is because we sometimes use Traditional DAQ applications and sometimes DAQmx. Is this necessary?
Also, I would like the counter to initialize at 0V. Now it puts out 5 V after Reset Device. I am using the NI6715 PCMCIA card. Right now, I reset the device and then ask for 2 ticks high (the minimum) and 1000 ticks low with the Idle State on Low. Then I call for Start Task and Wait Until Done to force the counter low. There are times when the counter needs to be forced high. With DAQmx, what is a good way to toggle the counter as needed? The counter is controlling a switch that sometimes needs to pulse and sometimes needs to remain in one position or the other.
Thanks,
Peg

Hello Peg,
Reset device is only necessary if the device is left in a state that
the driver will not be able to communicate. This can happen if a
previous task is not stopped/cleared and a new task is created or
sometimes when going from one driver to another (Traditional DAQ to
DAQmx or vice versa).
If you are not getting an error when you start your code, the reset is
not necessary. If you happen to get an error, you can manually reset
your device in MAX, or you can even conditionally reset the card in
your code (i.e. try to create and start your task and if an error
occurs, call the reset device function and rerun the code.
You do not need to completely run a task to set the idle state. You
can use a DAQmx Control Task function with the action set as "commit"
to make the idle state take effect. First you would configure the task
you eventually want to run on the counter, then commit it. Later when
you want the counter output pulse to run you can call the DAQmx Start
Task function. When you need to change the idle state, simply clear the
task and begin a new one in the same manner with the appropriate idle
setting. A digital line is an alternate option which can be simply
written high or low.
Hope this helps,

Obtain the determinate data from the NI-DAQmx Simulated Device

Dear All,
       How to config in MAX in order to obtain the determinate data from the NI-DAQmx Simulated Device?
       For example, the vi will run when the Digital I/O line is High, but using the Simulated Device, the result is random. In another word, I can't set the line is high or low.
       Would you please give me some suggestion?
       Thank you!
Hugo

Here is what I mean of stopping the DAQmx stimulated device. I do from step A - E; and step E is what I mean stopping the DAQmx stimulated device.
3. Use the NI-DAQmx Task in VI Logger Lite to complete a data logging application.
a. Open VI Logger Lite. If you do not have VI Logger Lite, download it or request a free CD.
b. Right-click My System>>VI Logger Tasks and select Create New.
c. Select Using NI-DAQmx and click Finish.
d. Select the NI-DAQmx task for the NI-DAQmx simulated device. Leave all settings in the defaults, and click Run task in the toolbar.
Figure 9. VI Logger Lite data logging task.
The data logging task begins. Data from the NI-DAQmx simulated device is displayed in the Real Time Data viewer.
e. Click Stop task.

After resetting devices in Netflix, Apple TV is not finding my Netflix account

Apple TV was reporting that it couldn't connetct to Netflix and to try again later. My MacBook and Wii were fine. After several days of this, I reset my Apple TV settings and reset my devices in my Netflix account. All devices are back up, including my iPhone, except my Apple TV. Because I reset devices in Netflix I had to reenter my login and password to Netflix. This worked on other devices. Apple TV said it couldn't find my account. I reset my password in Netflix and tried again. Again, all other devices are still working, but Apple TV cannot find my account. I'm confident that I'm entering the right login and password because I did it successfully on every other device.
Ideas?

I'm having the same issue. I live on a farm and the only internet fast enough is from my phone. I've connect the hotspot, but I get that same error when I try and play something. What does work, however, is if I pull up the netflix app on my phone (a different phone from the one I am using as a hotspot), play it from there, and airplay it on the apple TV. It's a big pain and it effectively slows my connection because I'm streaming it through the hotspot onto my phone and then pushing that back through the network onto the Apple TV. Any way to play it directly from Apple TV??

In MAX, I don't have the option to create a DAQmx Simluated Device. Why not?

I'm new to LABView. I installed the software, including the Measurement & Automation Explorer (MAX). Within MAX, I am trying to create a DAQmx Simulated Device, as suggested in a training guide (which I quote below). I don't have the option to create such a thing upon right-clicking on "Devices and Interfaces". I am given the option to create a new GPIB-VXI Interface, a Port, VISA TCP/IP Resource, and GPIB-ENET/100. I'd appreciate if someone can help me to create a simulated device according to the following steps, given that I currently lack the option "NIDAQmx Simulated Device":
3. Create a simulated DAQ device for use later in this course. Simulated devices are a powerful tool for development without having hardware physically installed in your
computer. Right-click Devices and Interfaces and select Create New…»NIDAQmx Simulated Device. Click “Finish”.
4. Expand the M Series DAQ section. Select PCI-6220 or any other PCI device of your choice. Click “OK”.
Thanks.

It sounds like you didn't install DAQmx. Open MAX and get a list of the software present. If you don't see DAQmx listed, install it from the CD/DVD or download the latest version.

IOS 5.0.1 upgrade, devices hangs in shuffle mode

Hello, I have an original iPad and the newest iPod touch and ever since the iOS 5.0.1 upgrade, both devices hang after a while when playing either all songs or a playlist in shuffle mode. It gets to a point where the song playing doesnt match the song displayed then on the next song it hangs. At this point I have to close iTunes and start over. Sometimes it hangs after a few songs and sometimes after 30-40 minutes.
This has made shuffle mode unusable ( which is what I primarily use). It never did this prior to 5.0.1. Thoughts?

I did the back-up / restore option all from within iTunes. Still no problems so that appears to be the fix until Apple recognizes it and puts out a fix.

ISync 'Reset Device' resetting speed dial?

Hello, I am using an aftermarket plug-in to iSync with my SE w580i, as it is not officially supported by iSync, HOWEVER, I had this issue with my SE z520 which WAS supported officially by iSync, so I suspect that the plug-in is not at fault...
I have several numbers set up to speed dial, so I can press '1' (or any other numbers) and call, instead of having to enter the full phone number. I noticed with my old phone, and now with my new phone, that if I 'Reset Devices' (thinking that only my calendars and contacts will be reset), my speed dial gets reset and I have to reprogram it. In a way, I understand, as after the reset, the phone sees all new contacts, BUT if they have the same name, why is it a problem?

The "Reset Device..." command in iSync does exactly that - so any settings you've applied in the phone to specific Contacts (such as speed dials, custom ringtones, caller ID pictures) will also get wiped.
If you think about it, you assign a speed dial to a contact. Resetting the device wipes that contact, so the speed dial setting has no contact to be assigned to.
iSync is unable to retain (or even see/access) any of the custom settings you apply to contacts in the phone, so every time to reset the device you'll have to re-apply any custom settings.
This could also apply to changes to data within a contact, because Sony Ericsson phones don't allow a Contact to be modified over Bluetooth, so iSync has to delete the contact and re-send the edited one, thereby removing any custom settings applied to that contact in the phone.

PXI-6509 Error occurred at Reset Device

Greetings Everyone,
     I recently had three (3) PXI-6509's fail in one of my Test Stations. I tried to reset them in MAX and received the following message: "The device reset has failed. The error report from the device driver is as follows: Error -224903 occurred at Reset Device.". I also received "Error -50152". After that while I had the stores list up of all installed boards, the three (3) PXI-6509's removed themselves from the list.  I'm wondering what these error codes are telling me.  The pop up error dialogue box stated that the "Possible Reason(s): Internal Software Error occurred in Static_Digital_software". I'm also curious as to what this is relating to. I replaced all three (3) board from a NEW chassis that I'm bringing up for use and everything thing is fine. I tried plugging these failed boards into my other chassis and the computer will not even boot up. Thank you in advance for any information that you provide that will help me in understanding what may have caused this to happen. The system was working fine up to lunch time and after lunch is when the problems started.
Regards,
Scott
Solved!
Go to Solution.

Greetings Nick,
Here is the course of events that led up to the problem being described.
While testing UUT’s (Company Product): (PXI-1044 with PXI-8101(XP), GPIB Controller and various PXI cards installed)
Before Lunch everything was working well. It was after lunch that the following events took place.
a)     Test Sequence hung up during External Power Supply ramp up in which the D-I/O are used to switch relays inside the ITA (Interface Test Adaptor) to connect the DMM to the Power Supply that is in use at the particular time in the test sequence. This has happened a couple times before, but NO error ever happened and just re-booting the system cleared it.
b)     The next thing that was performed was shutting down TestStand and Labview.
c)     The next thing that was performed was executing “MAX”.
d)    Once in “MAX”, I normally try to RESET all of the PXI cards, which is usually successful, but not in this case. The error pop up came up with the two (2) different error codes (-224903 and -50152). Please explain what the “Static-Digital Software is?
e)     I shutdown “MAX” and Re-Booted the system.
f)      After Re-Boot completed, I executed “MAX” once again and clicked My System, Devices and Interfaces and PXI-1044 “Chassis 1”.
g)     I tried to reset the NI PXI-6509 “PXI1Slot7” and received the pop-up error as described.
h)    Upon clicking OK. The PXI1Slot7 and PXI1Slot8 removed themselves from the stores list of cards installed and the icon next to NI PXI-6509 “PXI1Slot9” changed from a little green board icon to a white board icon with a little red ‘x’ inside it.
i)      Next, I removed all three (3) PXI-6509 from a NEW chassis in a NEW TestStand that I planned to bring on line in a couple of weeks. I placed these boards into the TestStand that is failing and everything is working well once again. I ran some diagnostics and everything checks out OK.
j)      Next, I took the failing boards and placed them into the NEW chassis and the computer wouldn’t even boot up.
k)    Next I removed two (2) (PXI1Slot7 and PXI1Slot8) of the boards and tried to boot the computer and the computer booted up.
l)      I proceeded to execute “MAX” and check the stores list only to find that the board (PXI1Slot9) was not even in the category of the PXI-1044 Chassis1 but outside it and it also had the white icon with a little red ‘x’. It also affected the PXI-2575 in PXI1Slot10, which had a white icon and little red ‘x’. I removed the board from PXI1Slot9 and re-booted the system and PXI1Slot10 recovered with the normal green icon that is usually next to it.
What I need to understand is what “Static-Digital software” is and what the errors are telling me. The fact that three (3) NEW board installed into the chassis and function 100% tells me that there is something wrong with the three (3) boards that I removed from the chassis and that nothing else seems to be wrong with the chassis.
The fact that installing the three (3) boards into a NEW chassis and the computer not booting is something of concern. I’m trying to understand what could have caused this to happen in the first place so I can be prevented in the future.
Regards,
Scott

Cannot reset device via iTunes (Touch 1st gen)

I'm having serious problems with my iPod Touch 1st Gen.
When starting apps, I get back to the start screen after 2-3 sec.
Cannot sync with iTunes, nor reset device via iTunes.
Is there any way to factory restet the device, by pressing and holding buttons?
Thanks in advance,
Johnny

I don't know if your iPod 1st gen has this but my iPod 4th gen has this thing where you go to settings then general and at the bottom it says reset then click on reset all and earase everything

USB devices hanging system

So i recently decided to try my ipod in arch so i can finally dump windows. Everything seemed to run fine until the tracks were copying, then my wireless signal dropped by half, then i realized i had no connection at all. My wicd had frozen. So i thought maybe neither devices were running in usb 2.0. But they both show as using EHCI. So i rebooted my computer and tried again and it keeps happening. I thought it might have been KDE specific since i had issues before while copying albums to a pendrive.
I tried in Gnome, same thing. There was nothing in dmesg. All i could see was when i was restarting, the wicd daemon couldn't be stopped. Then i was thinking it could be the motherboard. It's an Asus M3A78 Pro, 780G chipset. Since it sometimes hangs on 'initializing usb devices' while posting. But i don't seem to have any usb issues in Windows. I'm using Arch 64-bit and the stock arch Kernel 2.6.28.

[edit]exciting update, sometimes attaching my ipod causes windows to reset instead of hang
Are we talking about an ipod only when this happens?
Have you tried removing all Apple software like iTunes?
What powersupply do you use?
Also turn off the restart on error in windows so you see the error.

PCI-MIO16XE-50 with DAQmx; Reset traditional driver

I am developing a C++ application using DAQmx on Windows XP. I have two boards for testing- a PCI-6229 and an old PCI-MIO16XE-50. Whenever I run my application, I get an error back when I attempt operations on the MIO16:
-89130 Device not available for routing.
The 6229 works fine.
The solution is to go to MAX, right-click on Traditional Devices and select Reset. An alert tells me that the driver was reset, then I can access the MIO16 from DAQmx calls.
Although I have Traditional NI-DAQ installed, I haven't been using it. Why should I need to reset it?
I am using NI-DAQ 7.1; would this be fixed by upgrading to 7.4?

There has been a recent (7.4 timeframe) fix for the PCI-MIO-16XE-50, but it has to do with DMA support under DAQmx, not the problem you're describing.
If you haven't been using traditional DAQ at all, I'm a bit stumped as to why you're seeing this problem. In the hopes that we can figure this out together, here's an explananation of what we did to make the Traditional DAQ & DAQmx drivers interoperable with each other:
Prior to DAQ 7.0, the behavior of nidaq32.dll was that when the DLL loaded, it would enumerate the configured devices, and initialize the driver code for each device. We changed this in DAQ 7.0 such that the device initialization wouldn't happen until the first API function was called to use the device. Also, we changed the device initialization code to call into DAQmx to disable the DAQmx driver for that device. Finally, we added code to re-enable the DAQmx driver when the Init_DA_Brds or Device Reset.vi was called (or when the "Reset Driver for Traditional DAQ" MAX menu option is invoked), or whenever the nidaq32.dll is unloaded from all processes.
So, you should only see the behavior you are seeing if the nidaq32.dll is loaded by a currently running process AND if a trad. DAQ API call has been invoked on the PCI-MIO-16XE-50 in that process. It makes sense that you're not seeing this behavior with the M-Series device, because it's not supported by traditional DAQ at all.
Can you double-check that there is not another process running on your system that has loaded nidaq32.dll? You can use the "process explorer" utility, available for free download from www.sysinternals.com, to search for processes that have nidaq32.dll loaded.
If you don't find anything, then this could be a bug. Since DAQ 7.4 fixed the DMA issue with the MIO, you'll probably want to get this version of the driver anyway, which may have resolved the issue (though I don't remember such a bug). If you can reproduce this with DAQ 7.4, we'll still have an unsolved mystery. In that case, let us know and we'll try to reproduce your problem here.
Good luck,
Joe Savage

After reset Mail hangs w/spinning ball on "Reading table of contents"

This problem is on a 17" monitor Power PC G4, 256mb DDR SDRAM.iMac, half ball bottom, with Mail, with Systems 10.3.9
After Reset, Mail is hanging with the spinning beach ball on "Reading table of contents." Quite a few emails are being retrieved and placed in the Dock before the hang, and Mail responds to mouse commands up to the "hang." Then a Force Quit is the only way to proceed. Other programs run OK, with Mail "hung."
The reason for the Reset is that my daughter reads "fan fiction," and can go through a hundred pages in an hour, and the computer gets so plugged up that it takes FIVE MINUTES to retrieve, then display another Safari window. Empty Cache does not help. So, to get things back to normal, a reset is required. Something went wrong on this reset.
This happened once before, possibly with OS-X 10.2, and I was advised to delete a file somewhere deep in Systems, and Mail apparently made a "new" file and all was fine from then on. My "guess" is that Mail then makes a new "table of contents."
Anybody know what file to delete? Or any other advice? At the moment, I am getting Mail with another IMac, with System 10.2
iMac 17" "half ball bottom" 1 GHZ PowrPc G4 Mac OS X (10.3.9)

Hello Jean.
When you use the term "reset", are you referring to a
computer restart?
On this PowerPC with 10.3.9, what is the hard drive
capacity and available free space?
If the problem Inbox mailbox is for a POP type
account, with the Mail.app quit and using the Finder
go to Home > Library > Mail > this account named
folder (named by the user name and incoming mail
server for the account) > INBOX.mbox.
Move the INBOX.mbox to the Desktop.
Launch Mail and if successful, a new (and empty)
INBOX.mbox will be created automatically by Mail
within this account named folder when receiving the
next message with this account.
This should allow the Mail.app to function properly
again while working on the old INBOX.mbox move to the
Desktop to recover the existing messages.
Control-click on the old INBOX.mbox moved to the
Desktop and at the menu window that appears, select
Show Package Contents.
List the package content file names and size of
each here.
I have had the same problem as Jean - did what you advised and now find mail runs find but need to rescue the old mail.
This is the package content of my old inbox:
content index 36 kb
content_index-computername.local-372 10.9 MB
info.plist 4 kb
mbox 939.1 MB
tableofcontents 1.5 MB
hope you can help me...

Google vendor ID authorization and reset device limits

Hello,
I recently purchased a book on Google Play. So I attempted to download ADE and transfer the book to my Kobo Mini eReader. I tried to authorize my devices and computer using Google. The first problem is that when I selected Google as an ebook vendor, I use my Google details to login, but it says that my information is not correct. I know that my Google ID and password are correct because just a moment ago, I used them to login to my gmail. This seems to happen to some people on here as well. Is there any fix for this at all?
The second problem is that after many times attempting to authorize both computers and kobo and failed, I reset my computer (I was using my university's computer and it runs on virtual machine). When I got the computer rebooted, I downloaded ADE and started the process again. But this time, when I opened the .acsm file from ADE, it said that my device limit is reached. I assume that this happen because I was on my university's computer and it uses virtual machine so everytime it reboots, it becomes a completely-new-and-different-computer (since there are a lot of students at my uni and each student has a unique log in details; everytime the computer reboots, it completely wipes out all of the information from the previous use, including installation, etc.). So I guess ADE treated my computer as a new device, hence the device limit reached. So my question is, how can I reset my device limits (I got this suggestion from google play support that to contact adobe for a device limit reset, that's why I post the question here.)
Thank you.

Don't you think it's about time somebody responded to this kind of problem?
The whole ADE business is a f'ng disgrace, with every roadblock known to man being thrown up when you try to "authorize" a computer. I've just tried to change a computer's authorization to be associated with an Adobe ID, and all I get is the message "You can only authorize this computer with an Adobe ID that hasn't been previously used to authorize any other computer or mobile devices. Please try again."
Of course if you are dumb enough to try again, you get the same result, over and over.
A computer died, I replaced it, now I'm getting this crap and wasting hours of my time.
As I said, a f***ing disgrace.

OS 4.5- Device hangs periodically

Hello,
I just upgraded to the Rogers version of the OS 4.5 for the Curve (8310)... Now the device appears hang or freeze for up to 10 minutes at a time... Periodically the device screen hangs or freezes and unless you pull the battery there is no way to get the screen to respond... If you wait about 10 minutes the device will start again... This appears to happen for most applications (IE I can be listening to music and the device will stop for about 10 minutes after playing 2-3 songs and then continue playing.. It also freezes on the main screen when the device is locked)... It has not frozen yet while I'm actually typing an e-mail... It almost appears that the device is doing something in the back ground like scanning a SIM card or responding to some OS request...
I had noted from one of the other forums that this could be due to a SIM card so I reformatted the card and reloaded the music and files back to the blackberry...
Any ideas on what this could be and how to stop it...
Thanks

I am betting you upgraded the OS to 4.5, and you have a Media Card in the device, and the OS is constantly rescanning the Media Card. Common issue for a few after an OS 4.5 upgrade..
Remove your Media Card, first, reboot and your BB should be fine.
Then read this on how fix the Media Card (courtesy of John Clark, another expert here in the Forum)
1. Removed the Media Card from the device and put in a card reader. This makes the rest of the process much quicker. However, you can do it with the card in the device.
2. Copy the entire contents of the card to your PC.
3. Put the card back in the device and go to Options >Media Card >Menu key >Format Card. This will wipe the card and reformat it. (if using a card reader remove the card and put it back in the reader.)
4. Now copy back JUST the media to the device. Do NOT copy back any "BBthumbs.dat" files or any system files. I went through the entire folder and deleted every .dat file before copying the contents of the music folder and pictures folders back to the device. The device will recreate these files. Also, I didn't copy the actual "music" folder but rather just copied the contents and pasted in the card's \Blackberry\music folder. Do this for each folder.
5. When finished put the card back in the device and try the Media App again. It should scan for music. If you have lots of music it can take 5-10 minutes. During scanning you can open the Music app and you should be able to see the songs moving around in the list as the device scans
If after transferring all your files back you still get a stuck scanning bar or device reboots then you have a conflicting file on the card. I've seen video files do this but it could be a music file too or (less likely) a picture file. Remove all the files you transferred and see if the reboots stop. Then add back each folder one at a time to see if you can narrow down to the folder that's causing it. Once you find the folder then you can narrow down to a particular file.
