InLine 33304X USB to Serial Adapter Cable with Ferrite, USB-A to 9-pin Sub-D Male

The InLine 33304X USB to Serial Adapter Cable is a reliable solution for connecting legacy serial devices to modern computers via a USB port. Featuring a USB-A connector and a 9-pin Sub-D male interface, this adapter allows for seamless integration of hardware such as modems, ISDN systems, and PDAs without the need for a dedicated serial port on your computer.

Advantages

This adapter cable is equipped with an integrated ferrite core that effectively reduces electromagnetic interference, ensuring stable and consistent data transmission. It supports data transfer rates exceeding 500 KBit/s and operates without requiring an interrupt, which simplifies system configuration. The compact design and simple installation process make it an efficient tool for maintaining connectivity with older peripheral equipment.

Suitable for

• Connecting modems to USB ports
• Integrating ISDN systems
• Linking PDAs and legacy hardware
• Industrial and office equipment communication

When it may not be suitable

This adapter is designed for standard serial communication and may not be suitable for high-speed industrial automation tasks that require specific hardware-level timing or non-standard voltage levels. It is also not intended for use with devices that require a physical serial port integrated directly into the motherboard for specific legacy software compatibility.

How to use

To use the adapter, connect the USB-A end to an available port on your computer and the 9-pin Sub-D end to your serial device. Since the device does not include pre-installed drivers, you must visit the manufacturer's website to download the appropriate driver for your operating system. Once the driver is installed, the system will recognize the adapter as a virtual COM port, allowing you to configure your serial device through your software settings.

What to consider before purchase

• Verify that your operating system is supported
• Ensure your serial device uses a 9-pin Sub-D connection
• Check if your software requires a specific COM port assignment
• Confirm that you have internet access to download the necessary drivers

Usage recommendations

For optimal performance and to minimize signal noise, ensure the cable is not tightly coiled and is kept away from high-voltage power lines. Always download the latest driver version from the official manufacturer website to ensure compatibility with newer operating systems.
