Why Digital Edge in Trigger.vi start to make some sort of timeout?

Hi I do a manual release on my hardwareboard by inserting a 5 volt source the triggerchannel selected a few seconds after I push the Start button.

The generation ever begins. But if I put the trigger very equal to the sample clock external works listed in annex vi.

For example, I use PFI7 as source of outbreak which is also the source of the sample clock.

Could someone explain to me?

Sincere greetings,

Lasse

We can't simply insert a wire with a 5 V potential to PFI6 for example if PFI6 is used as a trigger for "Start Digital Edge" daqmx - vi. The PIN is floating and inserting just 5V does not guarantee a low aboard high.

If I use a potentiometer to pull on the low channel first, and then increse the tension, the trigging happens.

  • Why does microsoft word has a Starter? Why it seems to load whenever you click on it?

    The computer is a compaq presario CQ57. What is the significance of a pause button. How can I restart the computer if I type this

    button. Is it possible to disable this feature?  Why the start of the 2010 microsoft Office feature seems to make it harder

    to use, I mean it loads for a long time before its opening? Why MicrosoftOffice 2010 uses the term Starter? Why not just say that it is a

    first instance? It gives the wrong impression. Isn't this just make things more confusing?  Should I try to load office 2007. I don't want

    be optional?

    Hello

    I too hate this pause button. It is for many people who want to play media without having to turn on the machine (well at loading Windows). Turning it off can cause some other headaches later.

    1. this is how Microsoft wants people to buy its full product later.

    2. I think that Office (not Windows) 2007 and 2010 the TWO ribbons of use, not like the old 2003, and I also hate. We are talking about recycling for 40 thousand people here, not just you and me.

    3 good Office starter is a marketing ploy. Misrosoft gives a little HP (and other vendors) in OEM of Windows license fees and other suppliers HAVE to advertise for Microsoft.

    You can remove Office starter if you wish by using the Microsoft.

  • Satellite L50 - C starts to make mechanical sounds of cracking

    Dear Forum,

    I bought a Toshiba Satellite for Christmas and I was very satisfied, until my laptop started to make sounds remarkable. Sometimes, often, when I was game for a period extended (1 to 2 hours), the laptop starts to make mechanical sounds of cracking. These sounds is different from a regular cooler sound. Instead, this looks like a gear in the cooler is hitting something. Is this normal, or should I worry?

    Kind regards

    Peter

    Looks like something is stuck in the fan.
    A Toshiba repair center should be able to remove it.

    If you got less than a month ago, it is still under warranty of 90 days (I think), so take it back to the Apple Store you got OR no matter what Apple Store close to you if you bought it online.

  • the analog inputs with digital edge trigger

    I am currently triggering a readout with a digital trigger using a 0 - 5v as the digital source encoder.  I am running LV 8.2.1 DAQmx 9.0 and a PCI-6259.  I use a VI I wrote and which is very similar to 'Acq & chart voltage-Ext Clk.vi', and using the one-pulse encoder connected to PFI8 as the clock source for the sample clock vi.  The only major difference is using the channel of the Z-trigger as a software reset inside the While loop with the DAQmx reading.  Currently, the sample clock doesn't allow that either read the lower edge or an increase of PFI8, so I get a sample by one-pulse.

    I need to double the rate of analog playback for a given tree rpm and encode them, so I need to read on the fronts and edges of the one-pulse encoder.  The sample clock can be reconfigured for the detection of changes and still read the PFI8 port to increase and decrease as inputs of physical channel, or do I have to configure detection of modification of the task/digital input for a single line and use the "ChangeDetectionEvent" as the source for the sample clock HAVE? Detection of Timing/change DAQmx can still use the signal in PFI8, or should I use DI ports, and which ports are DI should I use?

    Thanks in advance!

    In fact P0.8 is.  I was looking at the pinout for the 6251, no 6259.  Sorry about that.
