D57 The TYPE pins indicate to the Carrier Board the Pin-out Type that is implemented on the module. The pins are tied on
the module to either ground (GND) or are no-connects (NC). For Pinout Type 1, these pins are don’t care (X). PDS TYPE[0:2]# signals are
available on all modules
following the Type 2-6
Pinout standard.
The conga-TC175 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.

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. PDS Not connected to indicate
“Pinout R2.0”.

12V Pinout R2.0
Pinout Type 10 pull down to ground with 4.7k resistor
Pinout R1.0
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. Type 10 modules shall pull this pin to ground through a 4.7k resistor.
