BLACK BOX The World s Source for Connectivity SM Tech Reference: Pinouts for Keyboard and Mouse Interfaces his Technical Reference describes the pinouts defined for many different keyboard and mouse interfaces. Given the Tuncertainties about these mostly proprietary interfaces, and the speed with which new I/O devices render older ones obsolete, this document is not intended to be authoritative, comprehensive, or exhaustive. We hope you will find it useful as you study, shop for, build, or troubleshoot devices and cables; however, we make no claim that it is absolutely correct, and will not be responsible for any damages or losses resulting from its use please exercise caution. Notes: All connectors are shown in front view (wires exit from the rear). The pins on male connectors are typically metal prongs or teeth, while those on female connectors are typically metal-lined sockets or grooves. I. Keyboard Only and Integrated Keyboard/Mouse Interfaces. IBM PC/XT, PC/AT compatible and Commodore Amiga 000/000 keyboard Pinout on -pin DIN ( DIN- ) connectors: Keyboard Clock Timing Computer Ground Ground n/a Keyboard Data Data Keyboard + VDC Voltage Computer Keyboard Reset Control Computer. IBM PS/ compatible keyboard A. Standard pinout on 6-pin mini-din ( mini-din-6 ) connectors: 6 6 Keyboard Data Data Keyboard + VDC Voltage Computer Reserved n/a n/a Keyboard Clock Timing Computer Ground Ground n/a 6 Reserved n/a n/a This line/signal was used by XT and very early AT computers to reset the keyboard. Contemporary AT compatible computers either do not use it or do not connect it, and it is not connected on the Amiga 000 and 000. This interface is also used by many other computers, including the IBM RS/6000, some Silicon Graphics and HP workstations, the DEC Alpha, and the Commodore Amiga 000. These pins are normally not used or not connected.

ACCESS.bus-compliant pinout on 6-pin Shielded Data Link (SDL) connectors: 6 6 Reserved n/a n/a Keyboard Clock Timing Computer Keyboard Data Data Keybd/Computer + VDC Voltage Computer Ground Ground n/a 6 Reserved n/a n/a. Apple Desktop Bus (ADB Apple Macintosh keyboard and mouse) Pinout on -pin mini-din ( mini-din- ) connectors: Bus Data Data Keyboard/Mouse + VDC Voltage Computer Reserved n/a n/a Ground Ground Ground. Sun Microsystems keyboard and mouse Pinout on 8-pin mini-din ( mini-din-8 ) connectors: Ground Ground n /a Keyboard Transmit Data Keyboard Ground Ground n /a 6 Keyboard Receive Data Computer + VDC Voltage Computer 7 No Connection Mouse Receive Data Computer 8 + VDC Voltage Computer These pins are normally not used or not connected. The mouse transmits its data to the keyboard on this pin; the keyboard then adds its data and transmits it to the computer.

Commodore Amiga 000 keyboard Pinout on -pin DIN ( DIN- ) connectors: + VDC Voltage Computer Ground Ground n/a Keyboard Clock Timing Computer No Connection Keyboard Data Data Keyboard The Vocalyst keyboards are basically PS/ compatible with added audio-i/o support. They have a built-in mike, speaker, and headphone jack. PS/ compatible mice are attached to this keyboard using a standard PS/ mouse interface (see page ). When headphones are not plugged in, the Left and Right Headphone signals are summed and output from the keyboard s speaker. Current Vocalyst keyboards do not implement this signal, which causes compatible attached CPUs to automatically mute their audio output.

Most contemporary SGI computers use the regular IBM PS/ mouse interface (see page ) instead. This interface is designed to support several types of pointing-device peripherals, as shown in the table. These are linear 70-kΩ (±0%) potentials.
