The following functions are available on the connector:
•
Speaker: An 8 ohm speaker can be directly connected to pins 7 and 8 of J3. All
necessary drivers are on the VIPer.
•
Keyboard Disable: The keyboard can be disabled or locked up by shorting pins 9 and
10 of J3.
•
Hard Disk LED: The onboard IDE interface activates an external LED. The LED
must be connected anode on pin 16 (J3) and cathode on pin 15 (J3). No external
current limiting resistor is required since one is already present on the VIPer.
•
Reset: The VIPer can be reset by shorting pins 13 and 14 of J3.
