Two types of keyboard interfaces are used in Compaq systems: PS/2-type and USB-type. System
units that provide a PS/2 connector will ship with a PS/2-type keyboard but may also support
simultaneous connection of a USB keyboard. Systems that do not provide a PS/2 interface will
ship with a USB keyboard. For a detailed description of the PS/2 and USB interfaces refer to
chapter 5 “Input/Output” of this guide. The keyboard cable connectors and their pinouts are
described in the following figures:
