The clearest reason to buy is its practical combination of a three foot cable and a selectable 5 Volt output, which removes the need for a separate power supply when interfacing with low-voltage peripherals. In testing it behaved predictably on current Windows and Linux systems, and the industrial focus is obvious in the supported signal set and regulatory approvals.\u003c\/p\u003e\n\u003ch2\u003eKey Features\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDB9 Male Port:\u003c\/strong\u003e Adds a 3ft.
