Table 35 Module Type Definition Signal Description
Signal Pin # Description
TYPE0# C54 The TYPE pins indicate to the carrier board the pinout type that is implemented on the
TYPE1# C57 module.
TYPE2# D57
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).

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#

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 12 V 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 4.7 kΩ resistor.

Comment
TYPE[0:2]# signals are available on
all modules following the Type 2-6
Pinout standard.
The conga-TCV2 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.
Not connected to indicate "Pinout
R2.0".
