USB Connector
Use the Universal Serial Bus (USB) connector to attach one or more USB devices, such as a mouse, to the computer. USB is a peripheral bus standard that enables
automatic detection of USB-compliant peripheral devices.
PS/2 Connector
Use the 6-hole, miniature Deutsche Industrie Norm (DIN) PS/2 connector to attach PS/2-compatible devices such as a mouse, keyboard, or external numeric keypad.
If you reconfigure your hardware, you may need pin number and signal information for the PS/2 connector.
NOTE: Make sure that no books, papers, or other objects block the transmission of data between the two infrared devices and that
the two devices are within the 30° cone.
