J3472 Connector Pin Assignments 

This section covers the pin connections of J3472 only. 
 

4.3.1  Aircraft Power and Lighting 

Power Input requirements and Lighting Bus inputs are listed in the following tables.  The power-input 
pins accept 11-33 Vdc.  AIRCRAFT POWER 2 is for connecting to an alternate power source, such as on 
aircraft with two electrical buses.  Refer to Figure B-1 for power and lighting interconnections.

Pins 53 and 55 of J3472 are internally connected to form AIRCRAFT POWER 1.  Pins 30 and 32 of 
J3472 are internally connected to form AIRCRAFT POWER 2.  AIRCRAFT POWER 1 and AIRCRAFT 
POWER 2 are “diode ORed” to provide power redundancy. 

 

4.3.2 Lighting Bus 

The GMA 1347D can be configured to track a 28 Vdc or 14 Vdc lighting bus using these inputs. The 
GMA 1347D can also automatically adjust for ambient lighting conditions based on photocell input on 
the PFD/MFD by digital means.
