Adapt QCM serial port VIs for USB QCM

[Sicelo]

I am trying to adapt Labview VIs that use a serial port and use them a QCM that uses a USB port. Does anyone know how I can do this. I have limited labview experience.

The USB QCM gives me data for the thickness and mass gains of the materials deposited but I cannot correlate those mass gains with the pressures in the reactor. I need to correlate the mass gains with the pressures so I can know the pressure profiles of the materials I deposit. The serial port VIs (for a different QCM) save the data for the mass gain and the corresponding pressure but I cannot do that with the USB QCM. That is why I want to adapt the older programs which store all the information and use it with the new QCM.

Thanks

You would likely want to use VISA to communicate with this USB device.  If you get the VISA alias for the device, you should be able to replace your serial code with VISA code that does very similar things (such as read and write).  This link shows the kind of thing you should encounter when using LabVIEW to control a USB device.
