Note 1: Pull-up to 3V3 supply
Note 2: Pull-up to RTC-Voltage
Note: For Engineering build, 26 pin header is mounted, causing INTRUDER#, GND, SMBC and SMBD
signals (pin 1, 2, 29, 30) to be unavailable.
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.
+3V3
(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, for instance pin 10.
EXT_BAT The on board battery circuit makes sure that the external battery will not be recharged.
The external battery 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
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, WinNT, and Win2000.
FAN3OUT FAN 3 speed control OUTput. This analogue voltage output controls the Fan's speed.
FAN3IN FAN3 Input. 0V to +5V amplitude Fan 3 tachometer input.
+12V
TEMP3IN Temperature sensor 3 input.
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)
SMBC SMBus Clock signal
SMBD SMBus Data signal
