Tripp Lite Keyspan High-Speed USB to Serial Adapter, PC & Mac, USB-A to DB9 RS232 Male
Field work often means connecting modern laptops to legacy serial consoles on network switches and industrial hardware. This adapter translates USB signals to serial communication cleanly, showing up as a standard COM port on your system. It draws operating power right from the bus, so you carry one less wall plug in your kit.

How this one is built
Port assignment
Your machine recognizes the attached serial line as a standard COM port. Any terminal emulator or management utility that reads serial streams communicates directly with the attached device without special workarounds.
Bus power delivery
Power pulls straight through the USB connection from your computer. You do not need to hunt for an open wall outlet or carry a separate transformer block when troubleshooting equipment in the field.
Activity light
A small indicator on the body gives immediate visual feedback while you work. It shows operational status and flickers as data packets pass back and forth across the link.
Console connectivity
The male serial head mates with standard legacy serial cabling and terminal ports. It gives newer computers a direct path into switch consoles, modems, and diagnostic interfaces that lack modern USB jacks.
