be disabled through SETUP. A connector, utilizing PS/2 pinouts, is located on the rear
panel on the system PWA. To meet the requirements for UL compliance the Vcc pin
(pin 4) was connected through a fuse prior to connection to the external connector.

Universal Serial Bus Connectors
The Universal Serial Bus (USB) is a communications architecture that gives a PC the
ability to interconnect a variety of devices via a simple four-wire cable. The USB is
actually a two-wire serial communication link that runs at 12 megabits (Mbs) per
second. USB protocols can configure devices at startup or when they are plugged in at
run time. These devices have been broken into five major classes:
•
Monitors
•
Communication devices
•
Audio
•
Human input
•
Mass storage
More classes will be identified as the USB Standard matures.
The IN440EX is equipped with two USB Serial Ports. This permits connection of two
USB peripheral devices directly to the system without an external hub. If more devices
are needed, an external hub can be connected to either of the built-in ports.
