Easily connect serial devices through a USB port. Most modern computers and laptops don’t have RS232 (DB9) ports, making the use of legacy peripherals and high-tech devices which connect with COM ports almost impossible. The Manhattan USB to Serial Converter – with its serial RS232 (DB9) ports and Prolific PL-2303RA chipset – easily expands a single USB port to connect and support serial modems, barcode scanners, digital cameras, card readers, Ham/Amateur Radios, GPS, CNC machines, telescopes, embroidery machines, fuel injection controllers, PDUs, network switches and other devices. Quality Construction and Easy Installation Gold-plated contacts and rugged construction combine to offer a reliable connection between the computer and serial peripherals for consistent, trouble-free performance. Windows compatibility with plug-and-play installation and hot-swappability help provide seamless use without inconvenient and frustrating device conflicts.
