USB 2.0 to RS232 Serial Adapter Renkforce RF-6801264 — 1x RS232 connector

The Renkforce USB 2.0 to RS232 Serial Adapter RF-6801264 provides a single RS232 serial port through a USB 2.0 connection, allowing legacy serial devices to communicate with modern computers. This compact adapter enables connection of modems, industrial controllers, measurement instruments and POS systems to PCs or laptops that lack native COM ports. The adapter supports standard RS232 signal levels and is designed for straightforward installation with appropriate drivers for common operating systems.

Advantages

The adapter converts USB 2.0 to one RS232 port in a small form factor, minimizing desktop clutter and simplifying cabling. It offers reliable serial communication for devices that require legacy interfaces, reducing the need for older PCs or internal expansion cards. The plug-and-play nature with available drivers streamlines setup and keeps data exchange, configuration and control tasks consistent with existing RS232-based workflows.

Suitable for

• Connecting serial modems to modern PCs
• Linking industrial controllers and PLCs for configuration and monitoring
• Connecting measurement instruments and laboratory equipment
• Integrating POS terminals, barcode scanners or receipt printers with RS232
• Field service and maintenance tasks that require serial console access

Key specifications

• Interface: USB 2.0 (host) to RS232 (device)
• Number of serial ports: 1x RS232
• Supported signal levels: standard RS232 voltage levels
• Data rates: compatible with common serial baud rates (up to USB 2.0 practical limits)
• Connector type: 9-pin D-sub (DB9) serial connector
• Power: USB bus-powered, no external power supply required
• Form factor: compact inline adapter suitable for desktop and portable use

How to use

Install the appropriate driver for your operating system if required, then plug the adapter into an available USB 2.0 port on the computer. Connect the RS232 device to the adapter's DB9 connector using a standard serial cable. Configure the host application or terminal software to the correct COM port and match parameters such as baud rate, parity, data bits and stop bits. After successful configuration, the adapter facilitates serial data exchange between the connected device and the computer.

Usage recommendations

Use shielded serial cables and avoid excessive cable lengths to maintain signal integrity. Verify driver compatibility for your operating system and update drivers from the manufacturer if communication issues occur. For industrial environments, ensure secure mounting to prevent strain on connectors and consider USB port power limitations when multiple bus-powered devices are connected.
