Connecting the utility cable
The Multifunction connector, CN5, implements the following interfaces:
AT keyboard
Speaker output
System reset input
Battery input
Vpp to program 12V Flash SSD devices
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 circular DIN connector for the keyboard, a push-button for resetting the PC/
104 system, 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 39.
