Your barcode scanner, label printer, or old POS terminal has a DB9 port. Your new PC doesn't. That's the whole problem, and this adapter is the whole solution. Plug the DB9 end into your legacy device, the USB end into your computer, and you're back to scanning, printing labels, or running that PDA workflow. 45cm of cable gives you enough reach to sit the device on the bench without a tangle. No IRQ conflicts, no driver headaches. Data transfer over 230 kbps keeps it snappy for everyday retail and warehouse tasks
