Keep legacy serial devices connected without redesigning the endpoint. Digi EdgePort 301-1001-11 converts one RS-232 DB-9 serial port to USB, giving modern systems a practical bridge to older hardware that still depends on COM-based communication. The included non-captive 1 meter cable adds installation flexibility, making it easier to position the adapter where cable routing and access matter most. This is the kind of adapter teams choose when device continuity matters more than replacing proven equipment. It helps preserve workflows around barcode scanners, industrial controllers, lab instruments, and other serial peripherals that remain in service because they still do the job well. By translating USB to RS-232 at the edge, it reduces the friction of keeping mixed-generation environments operational. For infrastructure teams, the value is in controlled compatibility and fewer endpoint changes. Digi’s EdgePort line is built for environments where serial access must remain predictable, and this single-port model keeps the footprint small while supporting a direct connection path. When a legacy device is too important to retire, this adapter keeps it usable on current USB-based systems.
