Also, whilst the keyboard data stream is a serialised one, it's not RS-232, which is what your suggesting when you talk about serial ports - which is probably why figuerres introduced the possibity of it being an RS-232 device - I'd doubt it.
You'll also need to explain what you mean by doesn't work. eg it seems to be getting no power, etc.
Hi. I am sorry I got everyone mixed up. It has a ps/2 connector. It is working fine when I connect it to the ps/2 port of my desktop. It can read the barcodes and send the data to the desktop. However when I use a ps/2 usb adapter converter (my laptop doesnt
have a ps/2 port), my computer does not recognize the barcode scanner anymore. The adapter converter is working fine when I tried to connect other devices like a mouse.
