Note
1. Pins are protected on the module by a series schotty diode. Therefore, pull-down resistor is required on the carrier board for proper logic
level.

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-TS370 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

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 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
