4 Port Professional USB to Serial Adapter Hub with COM Retention

This Professional grade USB Serial Adapter converts a single USB port into four RS232 Serial Ports, allowing up to four serial devices to be connected simultaneously. Once connected, the adapter retains assigned serial COM port values, allowing the same values to automatically be re-assigned to the serial ports 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 to a host computer USB port, eliminating the expense of upgrading the serial peripheral for USB compatibility.
