DELOCK USB RS-232 -adapteri USB 2.0 – D-Sub 9 pistoke muttereilla, USB Type-A – RS-232, 1,8 m, musta

The DELOCK USB RS-232 Adapter converts a USB 2.0 Type-A port into a D-Sub 9 male RS-232 serial connector. The cable is 1.8 m long and the compact RS-232 housing with fastening nuts enables secure attachment to devices with a serial interface. The adapter is black and supports common serial data settings for connecting legacy equipment to modern PCs and laptops.

Advantages

The compact RS-232 plug offers small dimensions for easy handling and convenient connection in tight spaces. Gold-plated connector contacts improve contact reliability, while the FTDI FT232R chipset ensures broad driver support and stable USB-to-serial conversion. The included fastening nuts allow a secure mechanical connection to devices with a D-Sub 9 socket.

Suitable for

• Connecting modems and POS terminals to computers
• Interfacing industrial controllers and meters with PCs or embedded systems
• Using printers, scanners or other legacy serial peripherals with USB-only computers

When it may not be suitable

This adapter provides a USB 2.0 data connection and a standard RS-232 signalling interface; it is not intended for use where hardware-specific voltage levels or isolated serial links are required. It may also be unsuitable for devices that need a permanently wired serial connection with custom pinouts or for systems that require higher-speed or multi-port serial interfaces.

Key specifications

• Interface: USB 2.0 Type-A (male) to RS-232 D-Sub 9 (male)
• Cable length: 1.8 m
• Chipset: FTDI FT232R
• Supported data bits: 7, 8
• Connector contact plating: gold
• Colour: black

How to use

Connect the USB Type-A plug to a host computer's USB port and attach the D-Sub 9 male connector to the serial device, securing it with the supplied nuts. Install any required drivers for the FTDI chipset on the host system if they are not automatically provided by the operating system. Configure serial port parameters (baud rate, data bits, parity, stop bits) in the host application to match the connected device.

What to consider before purchase

• Verify the target device uses RS-232 signalling and a D-Sub 9 serial connector
• Confirm the required serial parameters (baud rate, parity, data bits) are supported
• Check whether driver support is available for your operating system
• Ensure a single, 1.8 m cable length is sufficient for your setup

Recommendations

The adapter is intended for standard USB-to-RS-232 connections; for noisy industrial environments consider using an isolated serial adapter and verify driver installation before deployment.
