Parallel port based daq and drivers

[ramkis]

Do the following third party parallel port based daq requires driver

Hi,

I couldn't open the PDF, would you try to give the information another way? - maybe a screenshot?  I also could not find the device using Google.  What does 'VAD' stand for? - this may help.

From what I did see, it is an interface board used for education/training.  We probably don't have an 'instant' LabVIEW driver for the board but if it comes with a DLL and some decent documentation, you should be able to get it working quickly.

Thanks,
Jim

Hi,

I could read the second attachment.  The device looks like it will be a lot of fun!!   It can be programmed in LabVIEW by using 'Port I/O VIs' - 'In Port' and 'Out Port'.  There are a lot of example programs in the document that use the functions of the device and can be easily re-written in LabVIEW.   I can probably help you get started - for now look at the In Port and Out Port VI's - Writing and reading to locations 0x378, 0x379, and 0x37A is all that is needed to control the device.

Thanks,
Jim

Thank you jim,

That means it wont require driver software to access this daq(VAD 104).Am I right........??

As u mentioned I cannot find port I/o vi in function palette(fun -connectivity). I don't have printer port in my laptop.

When I try to insert inport vi throgh labview help, it shows following error

Object not found.  Possible reason includes:

The object might exist in a different palette view.

The object might not be supported on a target in the project explorer window

The object might belong to an installed package that  now has an expired license...

But I can find inport and outport VIs in some example programme ...

Hi,

I noticed that the vi's are not accessable in Vista or Win7 because of security concerns.  I remember using these vi's a few years ago to use the parallel port as a digital port.  I also remember having some problems after updating XP and needed a DLL in order to get it to work. 

Do you plan on generating the software on the laptop and transfering to a desktop?  What OS are you planning to use?  I can do a little research and let you know what I find.

Thanks,
Jim

Hey,

I did a search on the LabVIEW board for "Parallel Port" and there was a lot of information.

The following link may be helpful for you:

After you get the In Port and Out Port functions working, the rest is pretty easy.

Thanks,
Jim

HELLOW JIM HAPPY NEW YEAR

I am using labview 2010 32 bit

My os is windows 7 64 bit

I cannot find those vi s in palette, but i can find it in labview help but i cannot insert those vi from there also...

I can  find those vi in example programs also...

i have one more doubt

I have read  parallel port can transfer 8bit of data at a time.

if so,how the daq i have mentioned earlier can able to transfer data more than rated through parallel port.

(That is if i use all the available digital i/o lines and analog i/o lines simultaneously...)
