2. AT CNX80, CONNECT SHIELD GROUNDS TO THE REAR OF THE
MOUNTING FRAME ON THE CONNECTOR PLATE -- THE SHIELD

TO PROVIDE SYNCHRO HEADING TO THE CNX80.
5. THE OBI SELECT INPUT TO THE CNX80 CAN BE USED TO SELECT
THE SOURCE OF THE BEARING DATA SENT TO THE RMI. WHEN
THIS INPUT IS OPEN, BEARING DATA IS DERIVED FROM THE GPS ;
WHEN GROUNDED, BEARING DATA IS DERIVED FROM THE VOR.
6. OTHER EQUIVALENT PARTS MAY BE INTERFACED TO THE CNX80.
SEE APPROPRIATE INSTALLATION MANUALS FOR THAT
EQUIPMENT.
