Signal
Description
CASE_OPEN#
CASE OPEN, 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 required.
SMBC
SMBus Clock signal
SMBD
SMBus Data signal
S3#
S3 sleep mode, active low output, optionally used to deactivate external system.
S5#
S5 sleep mode, active low output, optionally used to deactivate external system.
PWR_OK
PoWeR OK, signal is high if no power failures are detected. (This is not the same as
the P_OK signal generated by ATX PSU).
EXT_BAT
(EXTernal BATtery) option for connecting + terminal of an external primary cell battery
(2.5 - 3.47 V) (– terminal connected to GND). The external battery is protected against
charging and can be used with/without the on-board battery installed.
FAN3OUT
FAN 3 speed control OUTput, 3.3V PWM signal can be used as Fan control voltage.
FAN3IN
FAN3 Input. 0V to +3V3 amplitude Fan 3 tachometer input.
FAN4OUT
FAN 4 speed control OUTput, 3.3V PWM signal can be used as Fan control voltage.
FAN4IN
FAN4 Input. 0V to +3V3 amplitude Fan 3 tachometer input.
SB3V3
Max. load is 0.75A (1.5A < 1 sec.)
SB5V
StandBy +5V supply.
GPIO0..17
General Purpose Inputs / Output. These Signals may be controlled or monitored
through the use of the KT-API-V2 (Application Programming Interface).
EGCLK
Extend GPIO Clock signal
EGAD
Extend GPIO Address Data signal
EGCS#
Extend GPIO Chip Select signal, active low
TMA0
Timer Output
+12V
Max. load is 0.75A (1.5A < 1 sec.)
