Our county motor vehicle department uses handheld bar code scanners. Their current model has a keyboard wedge Y cable with a PS2 connector. We are replacing some of their computers and the new machines do not have a PS2 port for keyboard or mouse. Rather than buy a PS2/USB adapter for the old units, we purchased a Unitech MS180 barcode scanner that connects via USB. With no special programming, it correctly reads the bar codes on the DMV license renewal forms, titles, etc. for their software applications. However, the users report that the new scanner needs to be held so much closer to the document before it recognizes & scans the barcode. I cannot find any information or instructions on how to adjust the sensitivity or scan area (or whatever) that would help resolve this issue. The user's guide has several pages of bar code programming options but I am not familiar with the application's programming code or scanner configuration lingo to figure out what options might work. Does anyone have any ideas on this for me?
