Product information

Description

The StarTech USB C to RS232 (DB9) Adapter Cable, 40 cm, provides a direct connection between a USB Type‑C port and RS232 serial (DB9) devices. This compact, male‑to‑male cable enables legacy serial peripherals—such as PLCs, barcode scanners, receipt printers and serial modems—to communicate with modern laptops, tablets or desktops that offer USB‑C. The cable is USB powered and supports plug‑and‑play operation across common operating systems, simplifying integration in field service, industrial and point‑of‑sale environments.

Advantages

The adapter delivers a straightforward USB‑C to serial interface in a single cable, eliminating the need for separate adapters or external power supplies. Its 40 cm length balances portability and reach for desktop and mobile use. Cross‑platform compatibility with Windows, macOS and Linux reduces configuration time and supports varied IT environments. The cable’s black jacket and molded connectors offer a discreet, durable solution for both temporary and permanent installations.

Suitable for

Connecting PLCs and industrial controllers to modern computers
Integrating barcode scanners and receipt printers with laptops and POS systems
Linking serial modems and diagnostic equipment to USB‑C devices
Field service tasks where a compact, portable serial interface is required

Key specifications

Connector type: USB Type‑C (male) to RS232 DB9 (male)
Cable length: 40 cm
Power: USB bus‑powered (no external power supply required)
Compatibility: Supports Windows, macOS, Linux (plug‑and‑play)
Color and construction: Black jacket with molded connectors for durability
Compliance: CE and RoHS compliant

How to use

Plug the USB‑C connector into your host device and attach the DB9 connector to the serial peripheral. The cable draws power from the USB‑C port, so no external power source is necessary. On most systems the adapter is recognized automatically; if required, install available drivers for your operating system following the manufacturer’s instructions. Verify serial port settings (baud rate, parity, data bits, stop bits, flow control) in your application or terminal software to match the connected device.

Usage recommendations

For reliable communication, use the cable in environments within the host and peripheral manufacturer’s specified operating temperatures and avoid excessive bending near the connector ends. Confirm serial settings with the peripheral device before starting data transfer. In mixed OS deployments, test connectivity on each platform to ensure correct driver installation and port mapping.
