The names of the COM ports are printed on the top of the PCB. Depending on the specific ETX module,
LVDS (JILI) or digital (JIDI) LCD signals are supported.
5.2 Feature Connector
Feature Connector
VCC_UL +5V UL-protected with inductor (600R@100MHz, 1A)
BATLOW# Battery low input. May be driven low by external circuitry to signal that the system battery is
low, or may be used to signal some other external power management event.
RSMRST# Resume Reset input. This input may be driven low by external circuitry in order to reset the
power management logic on the ETX module.
SERIRQ Serial interrupt request. This pin is used to support the serial interrupt protocol.
I2CLK, I2DAT Clock and data line of I2C-Bus. Switched I/O-lines with approximate 10kHz. Do not use as
multi master. Intended for I2C and other simple I/O-devices.
SMBDATA, SMBCLK Clock and data line of SM-Bus. For future use. Do not use today.
GPE2# General-purpose power management event input 2. May be driven low by external circuitry to
signal an external power management event. Within the ETX module, this pin is commonly
connected to the chipset’s RING# input.
GPE1# General-purpose power management event input 1. May be driven low by external circuitry to
signal an external power management event. Within the ETX module, this pin is commonly
connected to the chipset’s LID# input.
EXTSMI System management interrupt input. May be driven low by external circuitry to initiate an
SMI.
GPCS# Reserved. Do not connect to this pin.
SMBALRT# System Management Bus Alert input. May be driven low by SMB devices in order to signal an
event on the SM Bus.
EXT_PRG Reserved. Do not connect to this pin.
ROMKBCS# Reserved. Do not connect to this pin.
BATT 3V backup cell input. BATT should be connected to a 3V backup cell for RTC operation and
storage register non-volatility in the absence of system power. (VBATT = 2.4 – 3.3V)
KBINH Keyboard Inhibit.
PWGIN High active input for the ETX-PC indicates that power from the power supply is ready. It can
also be used as low active reset input signal.
PWRBTN# Power Button Input. This input is used to support the ACPI Power Button function.
HLEDR Low active output signal, which indicates activity on IDE interfaces.
