I am trying to gather some information on a upcoming project. I have a instrument that outputs a serial UART stream. I would like to interface this with LabView. This is the product that I am planning to interface with. http://www.pressureprofile.com/products-digitacts.php I am just learning how to use LabView so this is all new to me, any help would be greatly appreciated.

First- I would recommend takinga look into the Basic serial read and write example that ships with LabVIEW. Second, RTFM (Read The Friendly Manual) for the device. A Google search for serial comms will provide a reasonable backround for how serial comms can be configured.
As to how to implement the specific serial protocol in LabVIEW-- well, use a VISA call to the serial port to configure the various properties of the VISA ser:instr class and IF you learn the equipment's expected settings and what, and when, it responds, the "nuts-and-bolts" of wiring your device driver becomes reasonably simple.

It looks like if you use the evaluation kit you will have a USB interface. If you do not use the evaluaton kit it looks like the data will come from the UART most of the time that means TTL data levels, you would need a level converter to get it to RS232 levels, something like a MAX232 .
