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) port 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.
