Connecting the utility cable
The Multifunction connector, CN5, implements the following interfaces:
• AT keyboard
• Speaker output
• System reset input
• Battery input
To use these interfaces, you must connect to the Multifunction connector, making sure the orienta-
tion of pin 1 is correct. If you are using the Multifunction cable from our cable kit, the cable provides
a small speaker, a 5-pin PS/2 connector for the keyboard, a push-button for resetting the PC/104 sys-
tem, and a lithium battery to provide backup power to the Real Time Clock.
To connect individual devices to the Multifunction connector, please see Multifunction Connector,
CN5 on page 35 .
