18. Feature Interface
18.1 Connector
The feature connector is available through the X12 connector (26
pins) and controls functions such as the PS/2 keyboard clock and
data, hard-disk LED, USB serial bus ports, and various ATX power
signals.
The following table shows the pin-out of the connector.

Notes: (
*)
To protect the external power lines of peripheral devices, make sure that:
-- the wires have the right diameter to withstand the maximum available current
-- the enclosure of the peripheral device fulfils the fire-protecting requirements of
-- IEC/EN 60950.
The current of the pins on this connector is limited to 0.5A.
18.2 Configuration
You cannot configure the Feature interface from the BIOS Setup
Utility.

Power Interface
H_LED (Hard-disk LED)
†
Signal shows activity on primary and secondary IDE drive.
Connect the cathode of the LED to the H_LED pin and the
anode of the LED to the VCC supply voltage pin. The
required 470R resistor is already mounted on board of the
coolMONSTER/VC and coolMONSTER/VE.
SPEAKER (Speaker Out)
†
This pin controls the speaker output. Connect the
loudspeaker between this pin and GND.
RESIN (Reset Input)
†
You can use this pin as a low active hardware reset.
Connect with GND to force a system hard reset condition.
LILED (Link Integrity LED)
†
This pin indicates link integrity on the LAN. If the link
is valid in either 10 or 100 MPS, the LED is on; if link is
invalid, the LED is off. Connect the LILED pin with the
cathode of a LED. Connect the anode of the LED via a 470R
resistor to VCC supply voltage. The 470R resistor is not
onboard of the coolMONSTER/PM.
SPEEDLED (Speed LED)
†
This pin indicates the speed of the LAN. The LED will be on
at 100MPS and off at 10MPS.
Connect the SPEEDLED pin with the cathode of a LED. Connect
the anode of the LED via a 470R resistor to VCC supply
voltage. The 470R resistor is not onboard of the
coolMONSTER/PM.
ACTLED (Activity LED)
†
This pin indicates either transmit or receive activity.
When activity is present, the activity LED is on; when no
activity is present, the LED is off. Connect the ACTLED pin
with the cathode of a LED. Connect the anode of the LED via
a 470R resistor to VCC supply voltage. The 470R resistor is
not onboard of the coolMONSTER/PM.
USB2-/USB2+ (Universal Serial Bus Port 2 -/+)
†
This is the serial data pair for USB Port 2 (controller 1).
5V_SB, PS-ON, PWRBTN (ATX Power Support Signals)
†
For ATX support please connect the signals in the following
