The first thing is to give us more information. A sentance of "we have encountered serious difficulties" is pretty vague, could mean that you hooked up the power backwards and burned down the building, or that you haven't figured out the communications protocol. What are you attempting to do, what have you done so far, what are the results/symptoms? We (the community of LabVIEW addicts) will be happy to help.
