TIS In/NMEA & VHF Out - Receives TIS data and transmits out both NMEA data, at 9600 baud, and
VHF frequency tuning information to a Garmin Nav/Comm radio.
SL30 Nav/Comm - Outputs frequency tuning and course selection data to an SL30, and receives
VOR/ILS signals to be displayed on the PFD.
SL40 Comm - Outputs frequency tuning data to an SL40.
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 Appendix
F.
Note the following when configuring the communication settings:
•
Each 4XX/5XX series unit must be connected to an Aviation/MapMX RS-232 input on one of the
GDU 37X units (in addition to the GSU ARINC connection). ARINC 429 data input from a
4XX/5XX series unit will be ignored unless a corresponding Aviation/MapMX RS-232 input is
also configured.
•
When connecting two GNS 4XX/5XX units to the G3X system, connect the Aviation/MapMX
RS-232 output from NAV 1 to an RS-232 input on PFD1, and connect the Aviation/MapMX
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.
GSU ARINC 429 Configuration options
The configuration options for the 2 output and 4 input GSU ARINC 429 channels are detailed in this
section.
The GSU ARINC 429 Configuration options only appear when a GSU 73 is connected to
the GDU 37X.
ARINC 429 Outputs:
EFIS/Airdata – Outputs EFIS and air data labels to a 4XX/5XX series unit. A second selection is used
to determine if the EFIS/Airdata output is addressed to NAV 1, NAV 2, or both (NAV 1+ 2). The
transmitted labels are as follows:
100P Selected Course 1
206 Indicated Airspeed
212 Vertical Speed
320 Magnetic Heading
