Signal Pin # Description
SMB_DAT# B14 System Management Bus bidirectional data line.
SMB_ALERT# B15 System Management Bus Alert – active low input can be used to generate an SMI# (System
Management Interrupt) or to wake the system.
LID# A103 Lid button. Used by the ACPI operating system for a LID switch.
Note: For proper detection, assert a pulse width of at least 16 ms.
SLEEP# B103 Sleep button. Used by the ACPI operating system to bring the system to sleep state or to wake
it up again.
Note: For proper detection, assert a pulse width of at least 16 ms.

Table 33 Module Type Definition Signal Description

Signal Pin # Description
TYPE0# C54 The TYPE pins indicate to the Carrier Board the Pin-out Type that is implemented on the module. The pins are tied on
TYPE1# C57 the module to either ground (GND) or are no-connects (NC). For Pinout Type 1, these pins are don't care (X).
TYPE2# D57

The Carrier Board should implement combinatorial logic that monitors the module TYPE pins and keeps power off
(e.g deactivates the ATX_ON signal for an ATX power supply) if an incompatible module pin-out type is detected. The
Carrier Board logic may also implement a fault indicator such as an LED.

PDS TYPE[0:2]# signals are
available on all modules
following the Type 2-6
Pinout standard.
The conga-TS175 is based
on the COM Express Type
6 pinout therefore the pins
0 and 1 are not connected
and pin 2 is connected to
GND.
