delayed pulse Generator Config

[jbirdthe3rd]

I am using Labview 8.2 and I am trying to upgrade some labview 6 software that did not load into the newer labview. In labview 6, there is a VI called "Delayed Pulse Generator Config" which configures a counter to generate a single, delayed TTL pulse on its OUT pin. I cannot for the life of me find an alternate replacement VI in Labview 8. Is there a VI in labview 8 that will delay a pulse just like this VI in labview 6?

That VI was part of what is now called Traditional DAQ. By default, only DAQmx is installed but traditional DAQ is on the device drivers CD that you got with 8.2. As long as you are using the same DAQ board as before and configure MAX to use the old driver, you shouldn't have any problems.

Thanks for the response, but I have a question. How can I use both NI-DAQmx and Traditional NI-DAQ applications on labview 8.2? Do I need to install that Traditional DAQ library into my machine from the CD to make the old VI's work?

[Dennis_Knutson]

I don't think you can use both at the same time - at least not for the same DAQ board.

Yes, if you install traditional DAQ, the old VIs will find the functions and if you only use traditional DAQ, then it should work. If you have a new DAQ board that is not supported with traditional DAQ, then you will have to rewrite the program to use DAQmx.

i am facing a similar problem.

is there a way to switch from tranditional DAQ and DAQmx more conviently without reinstallation?

Is the Delyaed Pulse Generator Config.vi an actual VI that i can put it in the sub folder? or is it a feature that is no longer supported?

andrew,

If you are transitioning to DAQmx from legacy Traditional DAQ, then I would take a look at this excellent tutorial:

Transition from Traditional NI-DAQ to NI-DAQmx in LabVIEW

To start using DAQmx, you must install DAQmx. The version of DAQmx you should install depends on your LabVIEW version, but any LabVIEW version later than 8.5, you should install the latest DAQmx driver, 9.3.

As for the "Delayed Pulse Generator Config.vi": you will have to implement this functionality in DAQmx. The DAQmx pulse train examples in the Example Finder (LabVIEW » Help » Find Examples » Hardware Input and Output) are a good place to start.

Hope that helps.
