Signal Description
INTRUDER, may be used to detect if the system case has been opened. This signal's
INTRUDER#
status is readable, so it may be used like a GPI when the Intruder switch is not needed.
EXT_ISAIRQ# EXTernal ISA IRQ, (active low input) can activate standard AT-Bus IRQ-interrupt.
EXT_SMI# External SMI, (active low input) signal can activate SMI interrupt.
PWR_OK PoWeR OK, signal is high if no power failures is detected.
SB5V StandBy +5V supply.
SB3V3 Standby 3.3V. Max. load is 0.75A (1.5A < 1 sec.)
(EXTernal BATtery) the + terminal of an external primary cell battery can be connected
to this pin. The – terminal of the battery shall be connected to GND (etc. pin 10). The
EXT_BAT
external battery is protected against charging and can be used with or without the on
board battery installed. The external battery voltage shall be in the range: 2.5 - 4.0 V DC.
+5V Max. load is 0.75A (1.5A < 1 sec.)
General Purpose Inputs / Output. These Signals may be controlled or monitored through
GPIO0..7 the use of the KONTRON API (Application Programming Interface) available for Win98,
WinXP and Win2000.
FAN 3 speed control OUTput. This analogue voltage output signal can be used to
FAN3OUT control the Fan's speed. The output has 16 values in the range from 0 – 5V. For more
information please look into the datasheet for the Winbond I/O controller W83627.
FAN3IN FAN3 Input. 0V to +5V amplitude Fan 3 tachometer input.
+12V Max. load is 0.75A (1.5A < 1 sec.)
Temperature sensor 3 input. (Recommended: Transistor 2N3904, having emitter
TEMP3IN connected to GND (pin 25), collector and basis shorted and connected to pin23 (Temp3-
In). Further a resistor 30K/1% shall be connected between pin 23 and pin 24 (Vref).
VREF Voltage REFerence, reference voltage to be used with TEMP3IN input.
IRRX IR Receive input (IrDA 1.0, SIR up to 1.152K bps)
IRTX IR Transmit output (IrDA 1.0, SIR up to 1.152K bps)
