Triggering problems with IMAQ PCI 1411 using NI-IMAQ 2.6 drivers

I am having problems with the NI-IMAQ triggering mechanisms. I would like to use imgSessionWaitSignalAsync to register a call-back function to be repeatedly called on rising edges on the external trigger line. Now the external trigger line is connected to a photocell that is low when there are no objects in front of it and is high when there is an object in front of it. Unfortunately, when running my application, the callback function is not always triggered when an object moves in front of the photocell, and it is often triggered when no object is in front of the photocell. The callback function is not called anywhere else in the code.
An engineer at my company hooked up an oscilloscope to the trigger l
ine and we found that the photocell performs as expected. So I am looking for help to ensure that every time an object starts to pass in front of the photocell, the callback function will be triggered.
System Details:
Windows 2000 PC
Visual C++ 6.0
2x IMAQ PCI 1411 installed(one is revision A, the other is revision C.) I have the same problem even if I switch to the other card.
NI-IMAQ 2.60.0 drivers
Thanks in advance,
Michael

Bruce,
In fact that was my problem. The XC-73 operates at 30 Hz. My strobe
lighting was not triggered at 30 Hz. Once they matched, the
interlacing problem I described went away.

Imaq pci 1411 soft triggering?

How do you trigger a IMAQ pci 1411 without using the external trigger. I'd
like to triger it based on an event from a sub VI.
I don't realy want to use the external trigger for this.
Thanks
Champlain Landry

You could use occurences.
In the image acquisition VI, use a sequence with sequence 0 containing "Wait
on occurence" and sequence 1 containing one of the IMAQ sub-VIs (IMAQ
Start.vi or IMAQ Snap.vi or IMAQ Sequence.vi or ....).
When you want to start the acquisition, set the occurence from anywhere in
you application.

Imaq pci 1411

Hi all,
I am looking at upgrading an old system with NI IMAQ PCI 1411 card.
Could anyone tell me if that will work with the latest NI LabVEW/IMAQ drivers?
Thanks,
Peter.

Google them to confirm the settings that you need for the outgoing server, then check the setting you entered on the pad. Pay real close attention to the outgoing server name, and port. You may need to change in on the pad.

Problems with a shared calendar using Outlook 2007 and Exchange 2010

Hello all,
We are having a problem with sharing a calendar using Outlook 2007 and Exchange 2010.
I will start with some background. I have just started my position with this company. I have been working with networks for awhile at the small business level. I have not had much production experience with exchange. There is only myself and my supervisor
who has inherited a midsized network which was built by five previous techs that are no longer with the company. Of course, the previous techs did not leave much documentation, so the original hows and whys for our system setup has been lost.
One of the managers has a calendar she shares with some of our users. I believe this calendar has been in use since sometime in 2006. A mailbox was created to hold this calendar to keep it separate from the managers calendar. I am not sure what version
of exchange they were using at that time, but I assume there was one or two migrations of it getting to its current state on our exchange 2010 server. At some point it was observed that the other workers she was sharing with were not able to access it correctly.
I am not fully sure what the original problem was (possibly some people not being able to see or connect to the calendar), but it was decided to give everyone who needed access to this calendar full access permissions through exchange. Correct me if I
am wrong, but I believe that gave everyone connected the ability to do anything with the calendar. Of course the manager was not happy about that. This is where I started working on the problem.
I removed everyone, except the manager who wants to control the calendar, from having "Full Access Permissions". This did have the effect of making some people just able to see the calendar and not make changes. Though there were others that were
able to connect to the calendar who I thought would not be able to. The manager that originally created the calendar did try to manage access to it through the Outlook interface, though it currently does not seem to be fully in effect.
So, to get to the point of what we are trying to do, is there a way to get the original manager back into control of the calendar though Outlook? It would be preferred to be able to keep the history of what they tracked of this calendar, so starting a new
one would be something we would rather avoid. After that, getting all of the users that need to connect to the calendar reconnected with the correct access permissions and making sure they are all synchronized.
I realize this is a big mess, and your help would be greatly appreciated.

Hi Nigel,
How is the impact, just one user or all users, Outlook or OWA?
If just one user, it seems like an issue on the Outlook Client side.
Please trying to re-create new profile to fresh the caches.
Please runing Outlook under safe mode to avoid some AVs, add-ins and firewall.

To map the drive on your computer click on Start - RUN - type "\\192.168.1.1" and click ok... When prompted for Username and Password type "admin" and click ok... Now you will be able to see the folder which you have shared on your router, right click on it and select "Map network drive" and click on finish.
Now it will map the drive on your computer and you should be able to transfer the file from your computer to the USB drive.

Problems with a VBA Userform using Multipage (2) and DTPicker.

Hi
Problems with a VBA Userform using Multipage (2) and DTPicker (4)
On Page1 I've got 2 DTPicker, one for the date and the second for the time.
Same thing on Page 2.
Problem:
Only one set will work, if I close the Userform with" MultiPage"on page2, only that set will work.
Same thing if I close on Page 1 then just the set on Page 1 will work.
As anyone seen this problem and any work around you may think would help.
I'm using Windows 7 , Ms Office Pro. 2003
same problem on Windows Vista , XL2003

There are a number of issues relating to the way that date pickers are handled, but the most important is that their output is text. In order to get the values into Excel, you need to format the Excel columns as Date and Custom (time format) and convert
the output to the worksheet from text to date values.
Date pickers also display a few anomalies on multi-page forms, so you need a belt and braces approach. Personally I would put the code to call the form and enter the values in a standard module (as now in the example) and use a belt and braces approach to
maintaining the format.
I think you will find the example now works.

Can anyone please help me out in solving this issue.
May be the cause for this is :
1) The Wrong URL format
2) CLASSPATH is not setted properly..
Can you look more into this stuff.
Thanks,
Soorya.

Hi,
To access any database fromm XI, using the JDBC adapter, the corresponding drivers have to be installed on the XI server.
Just check this note 831162.
Also, check this PDF to install Drivers in XI,

I saved a new workspace and it did not help.
No problem before I went to Maverick.

Is anyone using iPhoto having a problem with the slide show using shatter where it does not let you put a title over photo?

Is anyone using iPhoto having a problem with the slide show using shatter where it does not let you put a title over photo? It use to work but it no longer lets you place a title over the opening photo.

Is your signature still current?(iPhoto '08, OS X Mountain Lion (10.8.4)) I can confirm this for iPhoto '11; Shatter will only show the text slide title between the slides. Ken Burns and Classic theme can still be set to overlay the caption and title directly over the slides.

I had a problem with slowness so I used "reset". The popup ran forever so I stopped it. Now I can't remove or add the program.

Blur video frame with NI PCI-1411 and JAI CV M-300 camera (urgent problem)

Hello,
I am new with Vision and I need some advice with a problem, which I encountered.
I have a computer with integrated NI PCI-1411 board, which is connected to a JAI CV M-300 camera. I am measuring a steel part which is positioned in a dark chamber. The part is put on a glass board and is illuminated from underneath with light.
The part is moving. I have to measure this part when it reaches the camera region. I have made a test with not-moving part and everything is perfect. Now, when I move the part I get blur frames from video (with these no part measurement is possible). I need specify, that the camera has no trigger, so it makes video all the time (this video is later inspecting with Vision Builder).
I have tried to change parameters in MAX, but no involvement. I have found no proper icd/file for the camera.
I also could use a SONY DXC-950P camera, if this is better.
How can I eliminate the blur from video frames? Or what am I doing wrong? Is the camera not good enough? Camera + trigger would get better images.
I have attached the video frame with moving object (static) and the blur video frame with moving object (dynamic).
Please give me a answer or ideas as soon as possible.
Thanks.

You are using an interlaced camera. It takes half the picture (every other line), waits a split second, then takes the other half of the picture (the other lines). When it puts the two images together, you can see the two positions it was in when the images were taken.
The best solution is to use a non-interlaced or progressive scan camera, which takes the entire image at one time. The Sony might be this type of camera, since it has a P in its name. I didn't look up the specs.
If you can't get the right kind of camera, your only other option is to use fields instead of frames. One field is the half image taken at one time. The image will be half the height of the original image, though, which can mess things up.
Another possibility is the reduce the resolution of the image. If you take every other pixel in both directions, you will have a very clear image that is half the size of the original. You can do this with Extract in LabVIEW, not sure if it is available in VBAI.

Problems with a PCI-7344 motion controller

Hi all,
I've run into a weird problem with a NI PCI-7344 motion controller, where I
have a program that provides the motion control for my program that works
reasonably well, but when I make minor changes gets motion errors. The changes
are not specifically to the motion parts, just changing a couple of globals
that provide communication with another part of the program (and another piece
of hardware). The errors I get indicate that I am trying to enable limits
switches at the wrong time in my program. I will add that I do not get any
errors when I go through the program in debug mode
Tnx,
P.W.Monroe

The portion of my program that gets the errors uses the "Flexmotion" Find Home
and Find Index routines, which are built into the 7344 controller. In the
exampes for using these VIs, they are followed by a loop that has a VI that
monitors the status of these VIs for completion, both move complete and Home or
Index Found. The globals that I mentioned are being used to terminate the loops
if an error condition occurs elsewhere, and do not cause the program to do
anything other than terminate looking at the status and then go into a wait
loop. It crashes when it goes into the loop when I substitute a different
global, which is baffling to me, as they aren't triggering something that would
result in a race condition.

Problems with older PCI-Videocards on K8N SLI Platinum ??

Hi there,
i just recieved my K8N SLI Platinum (without NEO) yesterday. Unfortunatly my new PCIe-Videocard isn't here yet,
so i just built my rig with an old S3 Trio64 to install Windows etc. and to have at least my PC for some surfing and so on...
The problem is:
The Card is marked with an ! in the device-manager. It says the card couldn't get its required resources, and that i'd have to
disable some other device of the system first to fully use the videocard. I checked for IRQ's, but the card has an exclusive one.
I put it in the second (middle) PCI-Slot on the board. Due to that error, the drivers are not installed correctly and the performance
of the display is ... well its even to slow for scrolling pages while surfing ... thats realy anoying, and my PCIe-card will not be here
until the end of next week
I even manged to get another old PCI-dinosaur, but with no luck. The same Problem persists. So i think it's some problem with
the board or some iossettings. The only thing regarding display in the bios was the PCIe / PCI switch which is correctly set to PCI.
So if anyone knows how to get an old PCI-card running in that board, please help me
[ApoC]

Well,
"f***ing up" the OS is not a problem, i got a GHOST of my perfectly fresh & clean OS.
I have disabled:
both SATA-Controllers (still running on good old ATA Samsung SpinPoint P80)
the FireWire-Controller (which is shown in Windows anyways )
I changed the videocard from PCI 2 to PCI 1, with the only result that it shares IRQ with the OnBoard-Soundblaster in slot1.
In slot2 it gets an exclusive IRQ. The problem is, i can't even see what resources are making trouble since Windows doesn't
show any information in the cards resource-infos but that it ain't working (say what?)
*sigh*

Edith says:
I remember problems with the APIC-Mode on many nForce-2 Boards. Could this still be a problem? Any infos on that matter yet?
