Notes:
[1] Multi-function pins used for analog pitch / roll outputs (60 mV/deg and 54 mV/deg) and isolated
synchro AC outputs (200 mV/deg).
Configuration determines the function of these pins. The
analog pitch/roll outputs each are capable of driving a 1 kΩ load. See Section 4.2.4.3 for details
on the isolated synchro outputs.
The GAD 43 provides AC pitch and roll outputs intended for emulating gyros such as the King KI-256
and the Cessna/ARC G519. An input for 10 VAC reference voltage is also provided.
The GAD 43 provides DC pitch and roll outputs intended for emulating gyros such as those used in
Century autopilots.
DC pitch and roll outputs are referenced to GAD 43 ground.
Refer to Section 5.3.1.1 for configuration information.
