Hello, Peter.
I don’t know much Labview, but I know that other customers have had success controlling our products from LabView by using some sort of serial port control that allows them to calculate and send bytes on a serial port. This post shows how to control the Maestro using LabView, and it might be useful to you:
Please note that the Maestro has a different serial protocol than the jrk, so you would have to change the bytes that are being sent. You should also set your jrk’s input mode to “Serial” and set its serial mode to “USB Dual Port”.
