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 FTDI FT232RL 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 InstallationGold-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.

Connects a Barcode Scanner or Other DTE Serial Device to Your Computer’s USB-A PortThis five-foot serial RS232 to USB adapter cable turns your computer’s USB port into an RS232 serial port and avoids the expense of upgrading your reliable serial devices. No external power source is needed. Just connect the cable to your computer and insert the included CD into your computer’s CD drive in order to launch the driver and assign the cable a COM port. It supports USB 2.0 specifications and data transfer speeds up to 230 Kbps, which is almost twice as fast as a built-in serial port. It is backward compatible with USB 1.1 devices.COM Retention Feature for Convenient Reassigning of COM Values to PortsThe hot-swappable RS232-port-to-USB adapter with built-in FTDI chipset offers COM retention. It automatically reassigns the same COM port values to each port, so when the cable is disconnected or the system is rebooted, no additional configuration is needed. The cable also supports remote wake-up and power management.Double Shielding Protects Your Data from Destructive Line NoiseFoil and braid shielding helps fight against electromagnetic interference and radio frequency interference (EMI/RFI) that impedes your signal and can distort or destroy data. The auto-sensing feature solves DCE/DTE conflicts without the need for cross-wired serial cables or adapters.3-Year WarrantyThe U209-005-COM is backed by a 3-year warranty, ensuring reliability and performance.
