USB Connector

The USB connector supports the use of a USB hub device to attach multiple devices. USB
devices are typically low-speed peripherals such as mice, keyboards, printers, and computer
speakers. The APR docking solution has two USB connectors.
NOTE: If you are using a USB external keyboard, do not enter the System
Setup program by using a keyboard command on the external keyboard.
Instead, press <Fn><F1> on the computer's keyboard.
PS/2 Connector
Use the mini-Deutsche Industrie Norm (DIN) PS/2 connector to attach PS/2-compatible devices
such as a mouse, keyboard, or external numeric keypad.
NOTE: If the computer is in standby mode when you attach a mouse, you can
use the mouse when the computer resumes normal operation. Otherwise, you
must reboot the computer to use the mouse. While the mouse is attached to
the computer, the DualPoint™ integrated pointing device is disabled.
Connecting an External Mouse
You can attach a PS/2-compatible mouse to the computer's mini-DIN mouse connector, as
shown in Figure 4.
