Why choose this product

Bridge Your Old and New Tech

Many critical industrial, scientific, or older computing devices still rely on RS232 serial ports. This TRIPP LITE adapter, imported directly from the USA, ensures you can connect these vital legacy systems to your modern USB-equipped computers. Unlike generic adapters, its premium double-shielded cable with gold-plated contacts and tinned copper braid minimizes interference, safeguarding your data integrity. This imported solution offers a reliable bridge, preventing costly equipment obsolescence and maintaining operational continuity for your specialized needs.

Who Should Buy This vs. Who Should Skip

Ideal for engineers, IT professionals, or hobbyists needing to connect older serial printers, lab equipment, industrial controllers, or legacy modems to a computer. It's perfect for users who require a stable, interference-free connection for data logging or device control. Skip this if your device uses a different serial standard (e.g., RS422, RS485) or if you need a USB-to-Ethernet or USB-to-parallel connection. Also, ensure your target device has a true RS232 serial port and not just a proprietary connector.

How to use

  • Connect the Cable to Your Devices — Plug the USB-A end of the TRIPP LITE adapter into your computer's USB port. Connect the DB9 or DB25 end (using the included adapter if needed) to your RS232 serial device.
  • Install Drivers (If Necessary) — For most modern operating systems (Windows 10+, macOS, Linux), the adapter is plug-and-play. If prompted, install drivers from the manufacturer's website or the included manual.
  • Configure Serial Port Settings — Open your serial communication software. Ensure the COM port settings (e.g., COM3, COM4) match the port assigned to the adapter in your system's device manager, and configure baud rate (230 kbps), data bits, parity, and stop bits to match your serial device.
