Cavo adattatore InLine USB a seriale USB Type-A connettore maschio / DB9 connettore maschio ca. 0,2 m

The InLine 33304 USB to Serial Adapter Cable converts a USB Type-A port to a DB-9 (RS-232) serial connection. At approximately 0.2 m long, the cable features a USB Type-A male connector on one end and a DB-9 male connector on the other, with a blue transparent jacket that allows visual inspection of the cable. It is intended for connecting legacy serial devices such as mice, modems and other RS-232 equipment to modern computers with USB ports.

Advantages

This adapter provides a compact and convenient way to link DB-9 serial devices to USB ports without requiring internal cards. The short 0.2 m length reduces cable clutter and the visible blue transparent housing helps identify the cable and inspect its condition. The standardized USB Type-A and DB-9 male connectors ensure compatibility with common ports and serial equipment.

Suitable for

• Connecting serial mice and pointing devices
• Linking external modems to USB-equipped computers
• Connecting RS-232 industrial or measurement equipment
• Temporary console access to network or embedded devices

Recommendations

Use this short adapter cable for close-proximity connections to avoid strain on ports; for longer distances, choose a longer shielded serial cable or a USB-to-serial adapter with an integrated longer cable. Ensure drivers are compatible with your OS and verify serial settings match the connected device.
