StarTech - 1 Port Professional USB to Serial Adapter Cable with COM Retention - Black

  • Model: ICUSB2321X
  • SKU: 9782977

The ICUSB2321X Professional grade USB Serial Adapter cable converts a USB 2.0 port into an RS232 serial port allowing you to connect to, monitor and control your serial devices. A durable, single cable design makes this the perfect solution for mobile technicians/administrators that require serial connectivity. Once connected, the USB to serial adapter retains assigned serial COM port values, allowing the same values to automatically be re-assigned to the port provided by the adapter in the event it is disconnected, then re-connected to the host computer.

This innovative adapter offers a professional grade solution for connecting legacy or industrial RS232 serial devices to more modern computers, or computers with unused USB ports - perfect for connecting serial modems, barcode scanners or any device with serial sync through USB, eliminating the expense of upgrading the serial peripheral for USB compatibility.

Backed by a 2-year warranty and free lifetime technical support.

    Would've been great if the specs had mentioned that this doesn't work with VISTA. Now I'm stuck with another piece of CPU aftermarket junk., that's not worth the time and money to return.

    No, I would not recommend this to a friend
