Integrated Autopilot – For use with Autopilots that use both ARINC 429 and bi-directional RS-232 data
(ARINC 429 output set to Autopilot). Integrated Autopilot is a proprietary serial format that provides
autopilot control softkeys and status annunciations on the G3X PFD. See wiring examples in
and Section 25.2.
Note the following when configuring the communication settings:
·
Each GNS 400/500, GNS 480, or GTN 600/700 series unit must be connected to a MapMX/
Aviation RS-232 input on one of the GDU 37X units (in addition to the ARINC 429
connection(s)). ARINC 429 data input from a GNS 400/500, GNS 480, or GTN 600/700 series
unit will be ignored unless a corresponding MapMX/Aviation RS-232 input is also configured.
·
When connecting two GNS 400/500, GNS 480, or GTN 600/700 series units to the G3X system,
connect the MapMX/Aviation RS-232 output from NAV 1 to an RS-232 input on PFD1, and
connect the MapMX/Aviation RS-232 output from NAV 2 either to an RS-232 input on the MFD,
or to a higher-numbered RS-232 input on PFD1.
·
Highlight the 'GPS1', 'GPS2', etc. fields on the Main Configuration page to verify which RS-232
and ARINC 429 inputs the G3X system is currently using for NAV 1 and NAV 2.
Vertical Power – A 3rd party LRU that integrates with the G3X to monitor and control the entire electrical
system via the GDU.
CO Detector - Receives data from a third-party carbon monoxide detector. Refer to the G3X Pilot's
Guide or the G3X Touch Pilot's Guide for further information.
