USB to RS232 converters create a virtual port in your operating system. You should make sure that you chose the correct port in your LV program (I believe you'll need to restart LV after connecting the USB device before you'll see the port in the VISA resource list) and that all the serial settings are configured correctly both in your program and in the OS (Control PanelSystemHardwareDevice Manager in Windows).Normally you can configure the port using VISA property nodes, so there shouldn't be any need to configure the device in the OS as well. Thanks for reply, but the problem is not it. Hi,When you use USB to Serial Converter then it's like your giving USB connectivity to your PC but latter it will convert to Serial by that converter. So it means at Laptop side you have USB device only but if you want to link any Serial (RS232) software/application with this USB to Serial Converter then you need two types of Driver1) USB device driver for that converter2) VCP i.e. Virtual COM Port, Which will create one virtual COM Port for your Software application and link it to USB Physical portGenerally it will create COM port with Address COM4, COM6 like that.

So you need VCP which will be dedicated for that USB to Serial Converter.ALL the Best:manwink.
