Alternative VIs for In Port.vi and Out Port.vi for 64 bit Windows 7 platform

[banyal]

Hi Need to use the printer port for my application. In Port and Out Port VIs was the simplest option in 32 bit Windows XP machine. Now I hear In Port and Out Port VIs are not supported in 64 bit Windows ( VISTA/7) machine. Is there any working alternative to In/Out Port.vi ??

Thanks in Advance

The issue you have isn't a LabVIEW issue, but a Windows issue. The increased security was started with Windows Vista, and MS locks down access to the ports directly. There may be a way to get to those ports, but it would involve low-level Windows API calls. Haven't a clue as to what they would be - you'd need to Google for this.

What are you using the printer port for? Are you trying to use it as a poor-man's digital I/O?  If so, you're far better off replacing the implementation with a low-cost USB-based digital I/O.

I wanted to use the Printer port for a 2-wire communication  with a temperature sensor IC. So yes it is bascially for digital I/O. Any idea if one can use VISA read/write for this purpsoe?

VISA can easily be used to solve your problem. If using a USB -> Serial adapter it's almost too easy. 🙂

I am aware of that. But I cannot at present afford to purchase the Serial/USB adaptor. LV driver too comes free with the hardware...

Hi !

Even am facing the same issue .Is it possible to read the  data through serial communication instead of using parallel port ?

My device is 64 bit Win 7 - LV 2013 SP1

Thanks
