Signal Description
INTRUDER#
INTRUDER, may be used to detect if the system case has been opened. This signal’s
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 Max. load is 0.75A (1.5A < 1 sec.)
EXT_BAT
(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
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.
Current draw is 3µA when PSU is disconnected.
+5V Max. load is 0.75A (1.5A < 1 sec.)
GPIO0..7
General Purpose Input/Output. The GPIO’s may be controlled or monitored through the
use of the KT-API-V2 (Application Programming Interface).
FAN3OUT
FAN 3 speed control OUTput. This analogue voltage output signal can be set to output
voltages from 0 – 3V3 to control the Fan’s speed.. For more information please look into
the datasheet for the Winbond I/O controller W83627.
FAN3IN FAN3 Input. 0V to +3V3 amplitude Fan 3 tachometer input.
+12V Max. load is 0.75A (1.5A < 1 sec.)
TEMP3IN
Temperature sensor 3 input. (Recommended: Transistor 2N3904, having emitter
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).
(Precision +/- 3ºC)
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)
