Signal Description
KBCLK/KBDAT/MSCLK/MSDAT
Keyboard and PS/2 mouse data and clock signal.
Do not use the keyboard and the mouse signals at the same time as the signals on the front bracket.
H_LED (Hard-disk LED)
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/P3 and coolMONSTER/C3.
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 cathode of the LED to the LILED 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/P3 and coolMONSTER/C3.
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 cathode of the LED to the
SPEEDLED 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/P3 and coolMONSTER/C3.
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 cathode of the LED to the ACTLED 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/P3 and coolMONSTER/C3.
USB2-/USB2+ (Universal Serial Bus Port 2 -/+)
This is the serial data pair for USB Port 2.
