USB–PS/2 Adapter Perixx 19998 — compatibility adapter for USB and PS/2 devices

Perixx 19998 is a compact USB–PS/2 compatibility adapter that allows connection between USB and PS/2 input devices. The adapter enables keyboards, mice and similar peripherals to operate across the two interfaces without additional driver installation, offering a straightforward hardware solution for systems that mix legacy PS/2 ports and modern USB connectors.

Advantages

The adapter provides simple plug-and-play functionality and a small footprint that fits into crowded workstations and desktop setups. It supports hot-plugging in many system configurations and requires no software configuration. The device is mechanically robust and designed for repeated insertions, making it practical for environments that swap input devices frequently.

Suitable for

• Connecting USB keyboards or mice to PS/2 ports on older PCs and terminals
• Using PS/2 keyboards or mice with systems that expose only USB ports (when supported)
• IT maintenance, testing and troubleshooting of mixed-interface workstations
• Office desktops and industrial PCs where legacy peripherals remain in use

Key specifications

• Compatibility: USB-to-PS/2 interface conversion for standard HID devices such as keyboards and mice
• Form factor: compact inline adapter suitable for constrained spaces
• Power: bus-powered from host connection; no external power required
• Plug-and-play: no additional drivers required for most operating systems
• Durability: designed for repeated plug cycles with common connector housings

How to use

To use the Perixx 19998 adapter, insert the adapter into the appropriate port on the host device (USB or PS/2) and then connect the peripheral cable to the adapter. Ensure both host and peripheral are powered according to their standard procedures. The adapter is intended for direct hardware-level conversion and typically works without driver installation; if a device does not function immediately, power-cycle the host or reconnect the peripheral.

Usage recommendations

Use the adapter with standard HID keyboards and mice. Avoid forcing connectors; align plugs carefully to prevent damage. For critical systems, verify compatibility with the specific peripheral model and host operating system before deployment. Store the adapter in a dry, dust-free environment to preserve connector integrity.
