5.03 CONNECTING INTERFACE DEVICES
(KEYBOARD, SPEAKER, RESET, LED)
Connector J5 provides all the necessary signals for connecting the keyboard, speaker,
reset, and keylock interface devices. The Multi-Function connector appears on Diagram 5-
3 at J5.
DIAGRAM 5-3: Multi-Function Connector Location
The following list includes approved vendors for the J5 connector's mating parts:
Amp 746285-3 [optional strain relief: 499252-8],
Robinson Nugent IDS-C16PK-TG,
Thomas & Betts 622-1630 [optional strain relief: 622-1641].
(16-pin flat cable connector).
The following functions are available on the J5 Connector:
• Speaker:
• Keyboard Disable:
• Hard Disk LED:
• Reset:
An 8 ohm speaker can be directly connected to pins 7 and 8 of
J5. All necessary drivers are on the board.
The keyboard can be disabled or locked up by shorting pins 9
and 10 of J5.
The onboard IDE interface activates an external LED.
The LED's anode must be connected to pin 16 (J5) and
cathode to pin 15 (J5). No external current limiting resistor is
required since one is already present on the board.
Manually reset the system by driving PBRES* to low state
(< 0.8 V).
