Product information

Description

The Trendnet TU-S9 Serial Cable is a USB-to-serial adapter with a blue USB Type-A connector on one end and a DB-9 (RS-232) connector on the other. It enables connection of RS-232 serial devices such as modems, industrial controllers, or legacy peripherals to a computer USB port, providing compatibility between older hardware and modern desktops or laptops.

Advantages

The TU-S9 offers plug-and-play connectivity for many operating systems and a compact, durable cable design that reduces signal loss and wear. Its standard USB Type-A to DB-9 configuration simplifies wiring to legacy serial equipment without requiring internal card installation.

How to use
