COM port doesn't recognized in Measurement and Automation

[Cobmetal]

Hi , im using labview 2014 , and i'd like to initialize an srial communication , i built an vi , using VISA , but i cant choose my com port .

I dont have an COM port on my pc , im using USB to COM converter , it works great with arduino and HyperTerminal . I tried to check the Measurement and Automation , and i found that my COM port is not recognized there.

What should i do ?

thank you in advance .

Hi Cobmetal

If you are using Arduino before you may leave your serial port busy, so LabVIEW does not recognize . Try resetting your port.

What chipset is in the converter?

I've seen this type of problem with si labs needing to be installed multiple times because of enumeration conflicts.

And what version of NI-VISA is installed?

And,  Now that I think of it,  Do you have the power mananger option turned off so Windows does not shut off the USB Port?
