How do I set a PFI to High on a 6602 Board with DAQ Traditional

[otheredward]

Dear All,

I am using LabVIEW 8.5 on 32-bit Windows XP with an NI 6602 DAQ board. In the past I've used DAQmx but for compatability with older software I need to do a few simple things using Traditional DAQ, which I have never used. Specifically I would like to make a simple VI that sets PFI 5 to high when the user presses a button and then low when they press the button a second time. How do I set PFI 5 for output and then write true to it?

Thanks,

Ed

Dear All,

Apparently its as simple as using the Write to Digital Line VI. However, the non obvious thing is the port width of the 6602 board is 32 not the default 8. Buried in the LabVIEW help files is a list of physical port widths that one must stumble upon. Like the bat cave. In the attached image of the super simple VI I've made the 16 refers to PFI 16. Good to know.

Best,

Ed
