writing to the pararell port with LabVIEQW 6.1 in W2000

[Garcas]

I am trying to communicate with a device attached to LPT1 with LabVIEW 6.1 running in Windows 2000.

First I tried directly with the VISA functions using as a resource name ASRL10::INSTR but the VISA WRITE function generates a timeout error (?).

As I couldn�t fix the problem then I tried with the IN PORT and OUT PORT functions in the LabVIEW Advanced pallete: but when I try to write in address 0x378 the OUT PORT function generates the following error: VI Out Port was stopped at Code Interface Node 0x1BC os subVI �Out Port.vi�

I have checked in Windows that the port address is correct, I have logged in as Administrator, so I don�t know why this is happening. Any ideas ?

Thanks a lot.

You cannot use the In Port and Out Port VIs on Windows2000. You will need to install the accessHW files by running setup.exe to make direct access to memory available on Windows 2000/NT. Refer to KnowledgeBase 0TL70ATL (linked below) for information about using the parallel port pins through direct memory access.
