DELOCK USB RS-232 Adapter USB 2.0 to D-Sub 9 Male with Nuts, USB Type-A to RS-232, 0.5 m, Black

The DELOCK USB RS-232 adapter converts a USB 2.0 Type-A port into a D-Sub 9 male RS-232 serial connector, providing a compact solution for connecting legacy and industrial devices to modern computers. It features a short 0.5 m cable, a black housing and is supplied with fixing nuts for secure attachment.

Advantages

The adapter offers plug-and-play connectivity for devices that require RS-232 serial communication without needing a separate serial port on the host. Its compact RS-232 plug design supports easy handling in tight spaces, cable glands and patch panels. Gold-plated contacts and a well-known FTDI FT232R chipset ensure reliable signal transmission and driver compatibility across many systems.

Suitable for

• Connecting meters and measurement instruments
• Point-of-sale (POS) systems and receipt printers
• Modems and routers with serial interfaces
• Industrial controllers and IoT devices that use RS-232

When it may not be suitable

This short 0.5 m cable is intended for close-range or external connections; it is not suitable for long-distance serial cabling. The adapter provides a D-Sub 9 male RS-232 interface only, so it will not replace devices requiring different serial standards or additional signal lines beyond the RS-232 specification.

Key specifications

• Cable length: 0.5 m
• Host connector: USB Type-A (male), USB 2.0
• Device connector: D-Sub 9 RS-232 (male)
• Chipset: FTDI FT232R
• Data bits supported: 7, 8
• Connector contact plating: gold
• Colour: black

How to use

Connect the USB Type-A plug to a free USB 2.0 port on the host computer and attach the D-Sub 9 male connector to the serial device. Use the supplied fixing nuts to secure the connection if required. Install drivers provided by the operating system or from the FTDI vendor if the host does not automatically recognise the adapter. After driver installation the serial port appears in the system and can be accessed by terminal software or device-specific applications.

What to consider before purchase

• Required cable length — 0.5 m is suitable for short, nearby connections
• Device compatibility — target device must use RS-232 D-Sub 9 male interface
• Host support — ensure drivers for FTDI FT232R are available for your operating system

Recommendations

Use the adapter for local, short-range connections and secure the D-Sub 9 connector with the supplied nuts to prevent intermittent contact. Verify and install the correct FTDI drivers for stable serial communication, and avoid running the cable near high-voltage power lines to reduce interference.
