Looking at the documentation available, I am not sure whether the panther can take step and direction signals or it can only take RS-232/485 commands for its programming. If the first one is the case, you can always use one of our 7334 motion controllers and the NI-Motion driver which comes with labVIEW libraries in order to achieve your motion. If the drive does not take step and direction signals but only RS-232 you can always use the labVIEW VISA functions to communicate the serial commands from your PC to the Panther. This woudl be more like making your own driver.
