The black 2-Port USB to Serial Adapter Hub with COM Retention from StarTech is a straight-through professional grade adapter that converts a single USB port to 2 RS232 serial ports, allowing you to connect to, monitor and control your serial devices. Its rugged metal construction and sturdy wall-mount brackets provide a robust solution for both harsh industrial environments and simple desktop installations.
Powered by USB, the device does not require a power outlet for most standard applications. For installations requiring more power through the RS232 ports, the hub supports connection of an external power adapter (not included) to the integrated DC jack or terminal block. Once connected, the adapter retains assigned serial COM port values, allowing the same values to automatically be re-assigned to the 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 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 serial peripherals for USB compatibility.
