Question about Computers & Internet
You shouldn't get a different value even if you read it multiple times... unless it isn't configured properly. If it is a RS232 interface, you have to ensure it has the correct baud rate and data bits.
Perhaps tell us more about the barcode reader. 1) Interface type. 2) model#
It sounds as though off hand it isn't working properly. Does the value you get seem close to the actual barcode? Are the numbers displayed on the barcode? Are you using a proper USB/PS2 adapter? It will be one with both mouse and keyboard sockets, if not be made of cord, with a box in the middle, with a USB cord on one end, and PS2 mous and keyboard socket on the other.
