Eaton U209-005-COM USB to RS232 Adapter Cable
The Eaton U209-005-COM Tripp Lite USB to RS232 adapter cable adds an RS232 serial connection to a computer through an available USB-A port. It uses an FTDI chipset, connects USB-A male to DB9 male, and supports serial data transfer speeds up to 230 Kbps over a 5 ft (1.52 m) cable.
USB to RS232 Serial Connectivity
The U209-005-COM is designed for computers that need to add an RS232 serial connection through USB. The USB 2.0 adapter uses a USB-A male connector on the host side and a DB9 male connector for the serial device.
The FTDI chipset supports Windows, Mac, and Linux systems. The adapter is USB-powered, so it does not require a separate external power supply.
COM Retention and Auto-Sensing
COM retention automatically reassigns the same COM port values to each port when the adapter is disconnected or the system is rebooted, reducing the need to reconfigure serial connections.
An auto-sensing feature helps resolve DCE/DTE conflicts without requiring cross-wired serial cables or adapters. The adapter also supports remote wake-up and power management.
Shielding and Serial Data Transfer
The Eaton U209-005-COM supports data transfer speeds up to 230 Kbps and is compatible with USB 2.0. Foil and braid shielding helps protect the serial signal from electromagnetic and radio-frequency interference (EMI/RFI).
Applications
- Connecting RS232 serial devices to computers through USB-A
- Point-of-sale printers
