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).

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.
TYPE10#

PD
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. Type 10 modules shall pull this pin to ground through a 4.7k resistor.

I/O Comment
TYPE[0:2]# signals are
PDS
available on all modules
following the Type 2-6
Pinout standard.
The conga-TC87 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".
