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 required.
EXT_ISAIRQ# EXTernal ISA IRQ, (active low input) can activate standard AT-Bus IRQ-interrupt.
Power SUpply OFF open collector output signal can be used as PSON input to an ATX
PSUP_OFF
PSU to keep it turned on until this signal gets inactive (Windows Shutdown etc.)
POWER UP, input signal has pull-up resistor to Vin. By adding resistor to ground
(threshold voltage ~1.5V) the minimum Vin can be programmed. If the input is lower than
POWER_UP
threshold voltage the board does not turn on. See also note in chapter "Power Connector
(PWR)".
SB5V StandBy +5V supply.
SB3V3 Max. load is 0.75A (1.5A < 1 sec.)
(EXTernal BATtery) option for connecting + terminal of an external primary cell battery
(2.5 - 4.0 V) ( – terminal connected to GND etc. pin 10). The external battery is protected
EXT_BAT
against charging and can be used with or without the onboard battery installed.
+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 KT-API-V2 (Application Programming Interface).
FAN 3 speed control OUTput. This 3.3V PWM signal can be used as Fan control voltage
FAN3OUT (0–3.3V DC in 128 steps) via a Fan Driver Circuit (not included) to program Fan voltage.
For more info, see W83627 datasheet. Default PMW output is 127 (100% = 3.3V).
FAN3IN FAN3 Input. 0V to +3V3 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 pin 23. Further
a resistor 30K/1% shall be connected between pin 23 - 24. (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)
