how can labview communicate with barcode scanner of USB interface

[RAVDM]

I have no idea that USB barcode scanner is within USBTMC or not

and there is no information available from the BCR supplier about the communication.

Is there anyone give me suggestions?

See if the manufacture has a driver like a DLL you could call from LabVIEW.  I always have used the bar code scanner that plugs into the keyboard input.  Very simple to integrate.

A usb bar code reader should not be a test & measurement class device. The ones I use are HID which means they install as another keyboard. Communication is just like entering text from your other keyboard which is likely to also be usb these days.

Hi Karthick

I could not read out the data from PS2 connected barcode scanner.

Could you please send your vi to me?

RAVDM is talking about a USB barcode scanner...

Have you tried opening an application like Notepad (if running Windows) and scanning a code?  Does it simply write the code to Notepad?

As Dennis explained, that is usually how a USB barcode scanner works. It behaves like a keyboard.

Can anyone share a simple source code on how to read the bar code using bar code scanner, and printout the data at textfile?

thanks in advanced

[Dennis_Knutson]

All that you need to read the scanner is a string control - just like you were entering the code from the keyboard. Could not get any simpler.

another noob question, what does this symbol mean?

where to find it?
