⚠️ Important Notice: Signal Direction & Port Assignment

1. Unidirectional Host-to-Peripheral Conversion: This active adapter operates strictly in one direction: from a USB-A host port (desktop computer, laptop, industrial PC) to dual PS/2 peripheral ports (keyboard and mouse). It cannot be used in reverse to connect modern USB keyboards or mice to older computers equipped with PS/2 ports.
2. Port Assignment Troubleshooting: The dual PS/2 female sockets provide dedicated channels for keyboard and mouse input. If either peripheral does not respond immediately upon connection, simply swap the two PS/2 plugs between the sockets.
3. Direct-Plug Dimensions: The adapter housing measures approximately 30 mm in width. On laptops or motherboards with closely grouped USB ports, ensure adequate adjacent port clearance.

Product Overview

The USB to Dual PS/2 Adapter offers a reliable, driver-free solution for connecting legacy PS/2 keyboards and mice to modern computers equipped with standard USB Type-A ports. Featuring a high-performance integrated controller chip housed in a durable translucent blue casing, this cordless direct-plug adapter frees up valuable desk space while enabling the continued use of cherished mechanical keyboards, trackballs, and vintage peripherals.

Key Features

• Integrated Active Controller Chip: Built-in intelligent IC handles active protocol conversion between USB HID standards and PS/2 Mini-DIN interfaces for lag-free typing and tracking.
• Dual PS/2 Socket Expansion: Occupies a single USB-A port and provides two dedicated 6-pin Mini-DIN female connectors, allowing simultaneous operation of both keyboard and mouse.
• Driver-Free Plug and Play: Standard USB Human Interface Device (HID) class compliance ensures instant recognition without manual driver installation or software setup.
• Compact Cordless Block Design: Eliminates dangling cable clutter and withstands frequent transport in computer repair toolkits and laptop bags.
• Hot-Swap Capability: Supports connecting and disconnecting peripherals without needing to reboot the host computer system.

Device Compatibility

Compatible with standard USB host systems and 6-pin Mini-DIN PS/2 peripherals, including:

• Host Systems: Desktop computers, workstations, laptops, industrial PCs, servers, and KVM switches with an available USB Type-A port.
• Operating Systems: Windows 11, Windows 10, Windows 8, Windows 7 (32-bit & 64-bit), Windows Vista, Windows XP, Windows 2000, Windows ME, Windows 98/SE, as well as modern Linux distributions and macOS.
• Supported Peripherals: PS/2 mechanical keyboards, standard membrane keyboards, PS/2 optical and ball mice, trackballs, barcode scanners, and legacy PS/2 input devices.

Note: Compatible systems and peripherals listed above represent functional reference examples. This list is not exhaustive; standard USB HID host ports and compliant PS/2 input devices are functionally supported.

Common Daily Applications

• Connecting beloved vintage IBM Model M or classic PS/2 mechanical keyboards to modern USB laptops and desktops.
• Maintaining and servicing legacy servers, industrial control terminals, and KVM switches that utilize PS/2 console inputs.
• IT diagnostics and computer repair workstations requiring versatile legacy peripheral testing.
• Simultaneous operation of a PS/2 barcode scanner and a keyboard on point-of-sale (POS) systems.

Frequently Asked Questions

Q: Can I use this adapter to plug a modern USB mouse into an old computer with a PS/2 port?
A: No. The internal conversion circuitry operates exclusively from a USB host computer to PS/2 peripherals. It cannot transmit data backwards from a PS/2 motherboard port to USB devices.

Q: Do I need to restart my computer when plugging in my keyboard or mouse?
A: No. While traditional PS/2 ports on older motherboards were not hot-swappable, this adapter converts the signal into standard USB HID protocol, allowing hot-plugging without restarting your computer.

Q: Why does my mouse or keyboard not respond after plugging it in?
A: Because the two PS/2 ports are routed to distinct keyboard and mouse controller channels, the plugs may be reversed. Simply swap the positions of the two PS/2 plugs, and the system should recognize both devices immediately.
