Dynon Avionics EFIS-D60 Installation Guide - Manual (Page 16)

Instrument Installation
PC CONNECTION FOR FIRMWARE UPDATES
On the EFIS 25-pin wiring harness
available from Dynon, there are three
wires bundled together, terminating in a
standard DB9-pin female connector. This
cable is 6’ long and pre-assembled for
connection to a PC-based laptop. Route
this cable to a convenient location that can
be accessed whenever you need to update
your product’s firmware or checklists.
If you did not purchase a harness from
Dynon, obtain a 9-pin D-sub connector
and make the three connections shown in the table.
To verify proper communication between the EFIS-D60 and the PC, use the Dynon Support
Program’s “Detect Firmware Version” function. Download the latest version of the Support
Program at

GPS CONNECTION FOR AIRSPEED FAILOVER
A yellow/green wire is spliced into the EFIS serial receive
line. In the event of loss of airspeed data (e.g., via pitot
icing), the EFIS-D60 uses GPS groundspeed. This allows the
EFIS-D60’s attitude to operate properly despite
compromised airspeed accuracy. Connect this yellow/green
wire to your GPS’s serial transmit line. See the table at right
for GPSs known to work.
To use the GPS-failover feature on your EFIS-D60, your
GPS must output either “aviation format” or the $GPRMC
and $GPGGA NMEA sentences in its serial stream. 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.
To verify your GPS connection, plug your pitot tube and taxi
at a speed greater than 25 knots. If the GPS is properly
connected, the alert GPS ASSIST is displayed on the attitude
indicator. This verifies that, in the event of airspeed loss in
flight, your GPS will be properly utilized for attitude
calculation.

PC USB CONNECTION
If you do not have a serial port on your PC, use the included USB-to-Serial adapter to connect
the EFIS-D60 to your PC’s USB port. If you are using Windows 2000 or XP, ensure that the
adapter driver CD is inserted in your PC before plugging the adapter into the USB port for the
first time. If you are using Windows Vista or Windows 7, ensure that you are connected to the
Internet and do not use the driver CD; the operating system will download the correct driver.
