Product Details

PS/2 Connector

PS/2 Click has a PS/2-style 6 pin mini-DIN connector used for connecting some keyboards and mice to a PC compatible computer system. It was irst introduced by IBM way back in 1987. It works on a serial, synchronous and bidirectional communication protocol.

Full N-Key Rollover

PS/2 Click is used in certain high-end keyboards, especially for gamer keyboards as it supports n-key rollover. This means that each key is scanned entirely independently by the keyboard hardware, and thus, allowing the high-end keyboards to handle any number of simultaneous keystrokes.

Why PS/2 over USB'

Though superseded by USB, PS/2 connectors are still used. The PS/2 connected keyboards are faster, and have slightly shorter effective scan intervals than their USB counterparts. PS/2 supports full n-key rollover, whereas USB keyboards can handle typically two to six keys at a time.
