Ugreen 20222 USB to RS232 (DB9) Converter Cable 2m

UGREEN 20222 USB to RS232 DB9 Converter Cable – 2 Meter Serial Adapter

UGREEN 20222 works as a USB to RS232 converter. Cable length sits at 2 meters. The USB plug goes on one end, and the DB9 serial connector sits on the other end.

Older equipment like barcode scanners, label printers, networking gear, POS systems, and industrial machines still run on RS232 serial ports. The problem is, most laptops and desktops stopped including serial ports years back. Manufacturers dropped them to save space and cut costs. This cable fills that gap when such devices need connecting to current computer systems.

Two-meter length gives enough room between the computer and the serial device. Standard desk setups and workstation arrangements fall within that reach. Not too short that it restricts placement, not overly long that excess cable clutters the workspace.

The DB9 end follows the usual RS232 pin layout. Nine pins arranged in the standard configuration that serial devices expect. Equipment reads the connection without compatibility issues on that front.

UGREEN built model 20222 for setups mixing old serial hardware with new USB-only computers. Technicians servicing legacy systems use these cables. Warehouse operations running older scanners need them. Small businesses with working serial printers that cost too much to replace rely on adapters like this one.

One cable does the job. Plug the USB side into the computer and the DB9 side into the serial device. Signal conversion gets handled internally through the cable. The computer sees a serial port; the device sees a serial connection. Both sides communicate.

UGREEN listed this under model number 20222. USB input, RS232 DB9 output, 2-meter cable length. Covers basic serial connectivity for machines missing native RS232 ports. Nothing extra packed in, nothing left out from what serial communication needs.
