Garmin GTN 650 unit:

Connecting the Garmin GTN 650 unit to the Dynon HS34 is the same way you would normally connect to the GNS 400/500(w) series units. Still requires 8 wires, all ARINC-429. Do not connect any serial lines to the Dynon HS34 or other Dynon equipment. You may still use the serial lines out of the GTN 650 for other equipment in your aircraft such as an autopilot if needed.

Please note that in this install, just like the GNS x30 installation, the "CDI" button has no function. The CDI button on the GTN 650 changes the analog output, but not the ARINC-429. You will be using the "NAV SRC" button on the HS34 to toggle between the NAV and GPS.

At this time I cannot provide any connection or configuration information until I can receive permission from Garmin International.

DO NOT USE THE SAME PIN OUTS FROM THE GARMIN x30 SERIES UNITS SINCE THE CONNECTORS AND PIN LAYOUTS ARE COMPLETELY DIFFERENT!!!!


Connect as follows:


HS34 (Setup done on EFIS, under setup menu then HSI):

   ARINC-429 Page:
              Input1: GAMA GPS
              Input2: GAMA NAV
              Speed: HIGH
              Output Data: ON
              Output Speed: High

Note that the HS34 can also support an ARINC-429 data rate/speed of "LOW" if your avionics setup includes other devices which require it be set that way.
