LabView 8.0 - Windows 8 - serial port

[andrea_001]

I have LabView 8.0 working under Windows 8, but cannot install the original device drivers because the new operating systemis not supported.

I need to use the serial comunication port; is there a solution? Maybe some dll library?

Thank you.

LabVIEW uses VISA for serial communication and that is most certainly supported. If you are using something else, why? Since you have not said what other driver you are using, impossible to say how difficult the conversion would be.

Dennis is inferring that you need to install the latest version of NI VISA that is compatible with Windows 8.  I'm actually surprised you managed to get LabVIEW 8.0 working.  It didn't want to work for me on Windows 7.  I highly recommend moving to LabVIEW 2012 or 2013 since those are supported for Windows 8.

Thank you for your reply. In fact I have now downloaded and installed the last version of NI-VISA and things seem to work. I have only noted that the time to shut down and to turn on the computer has now been significantly lenghtened since NI-VSA installation; any suggestion to lighten the system?

Thank you again.

Hello Andrea_001,

As one thing to try, this may be related to Windows Fast Startup as detailed here:

NI Tutorial: Frequently Asked Questions about Windows 8; My Windows 8 system is having issues detecting or using my hardware.

The Fast Startup feature involves a partial hybernate that caches driver settings on shutdown and reloads them without reinitializing when the system powers back on.  I've not looked into this, but I'd guess that this would affect your boot times, particularly if VISA needs to be re-initialized for any reason.
