It is going to be tough to give you explicit help because none of us on the forum have your hardware. We could not get your code to run if we wanted to.
Do you have any documentation for the control? The manufacturer would be the people to ask. A VB program would be very helpful because VB translates almost item for item into LabVIEW. Be careful about the ActiveX event callback in your code. The VI you attact to it will be called everytime the control fires that event regardless of the dataflow on your VI. Look in the shipping examples for help with that node.
