Controlling ProScan III X-Y stage with LabView

Hi there,

I'm new to LabView and this forum, please excuse me for asking sily questions!

I am on a project trying to use LabView for automation PRIOR ProScan III x-y stage to allow Gel mapping.

The stage is connected with the computer with USB COM 5.

I have tried to use SERIAL PORT with specified parametres

It is still not complete, I was just attempting to be able to establish some sort of controls . But it doesn't work.

I kind of followed what my collegue has previously done with a actuator control , and PX GX is what I found in the ProScan Mannual as commands (later I have realised it is the command in the Prior Terminal.

I have tried to use code provided in the PRIOR terminal, it all works, so I don't think the connection is a problem. 

Also I have found some sample LabView programme from PRIOR website

I sort of understood that it is an Invoke node, but I have no idea how this will allow me to connect with the stage. How do I get the reference input?

I've been so confused and frustrated with this recently, thus dicided to ask in the forum. Any help will be appriciated.

Thank you very much
