## Summary description

The ATEN KU2-232A Short is a compact USB to serial (RS-232) converter designed to connect legacy serial devices to modern USB ports.

The adapter enables straightforward data transfer and control without altering device hardware and simplifies integration in workstations and embedded setups.

## Long description

The ATEN KU2-232A Short is a compact USB 2.0 to serial (RS-232 / COM) adapter that connects legacy serial devices to modern USB ports. It uses an FTDI chip with a 96‑byte buffer, supports data rates up to 1 Mbps and is supplied with a driver CD. The short form factor and included 0.8 m USB extension cable make it suitable for installations with limited space. Compatible with a wide range of Windows versions and older macOS systems, the adapter allows connection of modems, cameras, chip programmers, card readers and other RS-232 peripherals.
Advantages
The adapter provides reliable USB-to-RS232 conversion using an FTDI chipset, offering stable data transfer up to 1 Mbps and a built-in 96-byte buffer. It does not require IRQ configuration and supports serial mice. Its compact short cable design plus the included 0.8 m USB extension cable simplify placement in constrained environments. Drivers are provided on CD for legacy systems.
Suitable for
Connecting RS-232 modems to notebooks and desktops
Interfacing industrial equipment and POS devices with USB-only hosts

How to use

Usage recommendations
For stable operation, use a direct USB 2.0 port on the host rather than an unpowered hub. If modern OS versions provide native FTDI support, confirm the driver version matches the adapter to avoid compatibility issues. Keep the CD or driver download source available for installations on legacy systems.
