There is a way, though I'm not sure it will be what you want.
BDC-COMM has a command prompt option.
LabVIEW can interface to the command prompt, or directly to library functions. I can tell you right now this will be a lot of work.

The other way would be to drop the BDC-COMM completely, and make your own. If you do this, make sure you use the firmware TI provides on their website, not the FRC firmware, because otherwise you won't be able to set the output. (That is, unless you are up to cracking the tokenization)

In short: you have the opportunity to do some low-level interfacing that we don't normally have to do in FRC. If you enjoy that, go for it! If you don't, it might be best to look into a different option.
