Hello Matias,
You must have LabVIEW 7.1 to use the PDA 7.1 module. You cannot install the PDA Module 7.1 with LabVIEW 7.0.
There are no new sound VIs for the PDA module. Instead, the LabVIEW sound VIs now work with the PDA module. The Sound Input and Sound Output VIs now work with either the PocketPC PDA module or the Palm module (as noted in the
Getting Started with the LabVIEW PDA Module manual, on page 15.)
These are the exact same VIs found in the Graphics and Sound >> Sound >> Sound Input/Output palettes in LabVIEW 7.0.
I hope this helps! Please let me know if I can provide further assistance or information.
