labview not detecting COM port

[Noelprashant]

Hi

I need to read the data from the PSoC using rs-232 and display on labview. I created VISA and created resource name control. But it is not detecting the COM ports present in the system. The only thing I get is refresh.

I tried pumping data and checked through hyperterminal and it works well.

Please help me in this regard.

Thanks in advance.

You need use Visa find resource for check if Labview find your port com. Example with visa find resource you can find : ASRL1::INSTR

ASRL1::INSTR is a COM port

After do that you need to use visa open visa read or write and visa close at the end of your program

Is ASRL1::INSTR a COM port? It is likely, but not necessarily! What if that VISA resource has been aliased to a different kind of port?

You can use the property node shown in the picture below to find out:

Let's go back a few steps: Have you installed NI-VISA? What shows up in MAX?

Backing up even further-

The Cypress PSoCs interfaces via USB.....(or I2C....but that would be ridiculus)

Did you install the Vitrual Com Port driver?  Does the Windows Device manager see the port?

Your device manager is showing an issue with COM8 (possibly a conflict).  I'm not sure what is up with the rest of your ports.  If you open up MAX (Measurement and Automation Explorer), do the ports show up in there?  What version of LabVIEW are using?  What version of VISA?
