Installation Guide Instruction Manual
Instrument Installation     
SL30 and/or GPS connection 
Depending on the number and types of Dynon units you own, 
you have several options for connecting a GPS unit and/or 
Garmin/Apollo SL30 to your Dynon system. The GPS can be 
used as a data source for the EFIS, HSI, and Fuel pages, as 
well as Dynon’s EFIS-based Autopilot. The SL30 can be 
used as a VOR, localizer, or ILS (localizer + glideslope) 
source for the HSI. If you wish to connect a GPS and/or 
SL30 to your Dynon system, read the section below which 
corresponds to your set of Dynon products. 
4-6    FlightDEK-D180 Installation Guide 
  If your system has an HS34, it is required that all 
GPS and NAV devices are connected to the HS34. 
The FlightDEK-D180 does not support directly 
connected GPS and NAV devices when an HS34 is 
installed in the system. Refer to the HS34 Installation 
and Configuration section on page 9-10 for device 
connection details. 
To use the GPS-related features on your EFIS and/or EMS, 
your GPS must output either “aviation format” or the 
following NMEA sentences in its serial stream: $GPRMC, 
$GPRMB, $GPGGA, and one of $GPBOD or 
$GPAPB. You must also have a supported cable 
that exposes your GPS’s serial transmit line. If 
you own a Garmin 430 or 530, in the 
UNITS/MAGVAR option, set the MAGVAR to 
AUTO. The FlightDEK-D180 auto-detects most 
GPSs, but may require a manual setting for 
some. This is true for communication with at 
least the Garmin 480 and maybe others such as 
the GX50, and GX60, and Bendix/King Skymap 
IIIc. From the EFIS menu, enter SETUP >HSI 
>EFIS_SERIAL; from the EMS menu enter 
SETUP >GLOBAL >EMS SERIAL. In that 
menu select the INPUT to be AVIATION and 
the BAUD RATE to be 9600. 
The following connection schemes assume that 
the external devices share a common ground 
with the Dynon product(s). If your GPS is 
battery powered, and not normally connected to aircraft ground, you must connect the ground pin 
on its serial output to a ground common to the FlightDEK-D180.

When a Dynon product is connected to a GPS, it will synchronize its Zulu clock to the time 
reported by the GPS. However, some GPSs, such as the Garmin 430 and 530, do not report time 
in their serial output stream. Dynon products have no way to synchronize to these GPSs’ clocks.
