BTW, barcode wands not only come with manuals more complete than a very expensive PC's manual, but they *must* come with decent manuals.
The wand can be a keyboard or a serial port to the PC, user's choice. So how do you configure the wand? You scan bar codes printed in the manual for the settings you want to configure.
@thekayfox I don't follow. The only ones I could get on the cheap are all USB.
@arielmt I wish they made USB versions.
