Max doesn't add cp2102 device

[Dennis_Knutson]

Why would you reinstall LabVIEW? If you were to reinstall anything, I would start with the USB driver, then NI-VISA, and then MAX.

Is the device's virtual COM port (VCP) showing up in Device Manager?  Can you communicate with it through an interface like HyperTerminal or PuTTY?

Honestly, it sounds like the driver's not installed.

If I remember right, the driver you download is just an installer for the driver.  There's a check-box in the downloaded installer to launch the VCP driver installer that isn't checked by default, so if you just next-next-next-finish through the installer the actual drivers probably aren't installed.

Yes, I communicate with Hyperterminal very well, where do i find the driver for recognize the CP2102 in MAX?

Is this link http://joule.ni.com/nidu/cds/view/p/id/2914/lang/it ok for NI-VISA driver?

If you're talking to it with HyperTerm/PuTTY, the VCP drivers are installed.  You're communicating with the device as a COM port.

Take that COM port and bring it into LabVIEW as a constant into the configure-serial-port.vi.  See the example I posted, but I don't see anything wrong with what you did either.

Ok, I resolve the problem, i installed the NI_VISA and the block diagramm works!!

Thanks to all
