Power Primary power input: +12V nominal. All available VCC_12V pins on the connector(s) shall be used.
VCC_5V_SBY B84~B87 Power
Standby power input: +5.0V nominal. If VCC5_SBY is used, all
available VCC_5V_SBY pins on the connector(s) shall be used. Only
used for standby and suspend functions. May be left unconnected if
these functions are not used in the system design.

NC pin out R2.0
PD pin out Type 10 pull down to ground with 47K resistor
12V pin out R1.0
A carrier can detect a R1.0 Module by the presence of 12V on this pin. R2.0 Module types 1-6 will no connet this pin. Type 10 Modules
shall pull this pin to ground through a 4.7K resistor.
