Metrologic USB Voyager scanner

I recently installed a USB voyager scanner. The scanner was working fine, however it only read 13digits. So i referred to the user manual and found the solution. However after doing this the barcode scanner stopped working. e.g. i scanned a product, it beeped however no digits appeared on screen or in notepad.

I then referred to the USB settings in the manual, and used the 'Enable USB Interface'.
This seemed to help, e.g. When i scanned a product details appeared in notepad however these details werent entirely correct. The code would appear 3times even after scanning once.

Is their another barcode or setting that i have to enable to resolve this?
