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
TYPE1# C57 on the module to either ground (GND) or are no-connects (NC). For Pinout Type 1, these pins do not matter (X).

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.
TYPE10# A97 Dual use pin. Indicates to the carrier board that a Type 10 module is installed. Indicates to the carrier that a Rev.
1.0/2.0 module is installed.

12V
This pin is reclaimed from VCC_12V pool. In R1.0 modules this pin will connect to other VCC_12V pins. In R2.0 this
pin is defined as a no-connect for Types 1-6. A carrier can detect a R1.0 module by the presence of 12V on this
pin. R2.0 module Types 1-6 will no-connect this pin. R3.0 module types 6 and 7 will no-connect this pin. Type 10
modules shall pull this pin to ground through a 4.7K resistor.resistor.

Description
Primary power input: +12V nominal. All available VCC_12V pins on the
connector(s) shall be used.
Ground - DC power and signal and AC signal return path.
All available GND connector pins shall be used and tied to carrier board GND

I/O Comment
PDS TYPE[0:2]# signals are
available on all modules
following the Type 2-6
Pinout standard.
The conga-TR4 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.
PDS Not connected to indicate
"Pinout R2.0".
