REMOTE ANNUNCIATE DATA
REMOTE ANNUNCIATE SYNC
These inputs read the remote annunciate data bus that the autopilot uses to tell its remote annunciator
panel what mode it is operating in.
The GIA 63 requires 4.7 kΩ pull-up resistors to +28 V
No pull-up resistors are required for the GIA 63W or GIA 63H.
The GIA 63W and GIA 63H will function properly if the pull-up resistors are installed in
the aircraft harness.
