In fact I pitched those 9-pin cable mouse devices years ago, but the pin-out is still good. Circular Mini-DIN Pin LocationsĮditor note it's been a number of years since I've had or seen a 9-pin mouse port on back of a PC. The personal computer uses a 5-pin mini DIN for the Keyboard interface. The Sun computer used a 8-pin mini-Din for the Mouse interface, also replaced by USB Sun Mouse Pinout. The MAC used a 4-pin ADB interface for the Mouse interface, now replaced by USB. D-Sub 9-Pin Connector Serial Mouse Pin Out Pin No.
The standard cable length is around 4 feet, 6 foot and 10 foot extension cables are also common for the PS/2 mouse interface.įor additional data on the DB9, refer to Dsub 9 Mechanical Dimensions. The Mouse interface runs using standard TTL signaling levels. Many new Motherboards just use the USB port as the mouse interface.
Most personal computers stopped using the serial mouse around the year 2000, in favor of a mini-DIN.įor a description of the electrical interface, refer to the RS232 page. The mouse used a female plug connector, while the board-side connector used a male jack connector. This page provides the pinout for a serial mouse, or a mouse that uses the serial port via a 9-pin D connector. The Mouse port found on most Personal Computers uses a 6-pin mini DIN connector and has the pin out shown the PC Mouse pinout page.Īll thought not as common as the PS/2 Mouse interface, a mouse may also be found with a serial interface. The serial mouse port is not in common usage.
