1. INTRODUCTION
This manual provides information about the physical, electrical, and plumbing installation of the
EFIS-D60, EDC-D10A and optional AOA pitot probe purchased from Dynon Avionics.
Additionally, this guide deals with setting up the installation-dependant firmware options.
Because you may not have purchased all the components, you need only read through the
relevant sections of this guide. Information about the operation of this instrument can be found
in the EFIS-D60 Pilot’s User Guide.
The EFIS-D60 uses solid-state sensor technology to give an accurate and easy-to-understand
display. To ensure accuracy in its readings, it is very important that you install the instrument
correctly and perform the specified calibration steps. This installation guide will help you
through that process.

2. WIRING OVERVIEW
Please follow these instructions explicitly as improper wiring can result in permanent damage to
your instrument and/or the accompanying sensors.
All electrical power and EFIS-specific lines interface with the EFIS-D60 via the female 25-pin
D-sub connector on the back of the instrument. Ensure that the unit powers on and that all
indicators display expected values before completing the final physical assembly.
Recommended Wiring Practices
For all electrical connections, use correct wiring techniques, taking care to properly
insulate any exposed wire. A short circuit between any of the wires may cause damage to
the EFIS-D60 and/or your aircraft. Make all connections to your harness before plugging
it into any of the components of the system. Do not make connections while power is
applied at any point in the system.
Dynon Avionics sells a wiring harness for all connections to the EFIS-D60. The harness is made
up of 22 AWG wire and meets Mil Standard MIL-W-22759/16 (Tefzel insulation). If you have
opted not to purchase this harness, please refer to the provided wiring diagrams for construction
information. We recommend that all wire you use also meets Mil Standard MIL-W-22759/16; all
wire supplied by Dynon Avionics (with the exception of thermocouple wire, which uses FEP
insulation) meets this specification.
When using any pre-manufactured harness, verify that each pin has continuity with the expected
wire on the wiring diagram. This test can be easily done with a multimeter. When verifying
harnesses, use the wiring charts and diagrams in this guide as your ultimate authority on pin
function (for any harness) and wire color (for harnesses purchased from Dynon Avionics).
Route all wiring such that there are no spots where it could chafe or break. Use appropriate strain
relief at all junctions between wires and connectors. We recommend that you secure all wires at
regular intervals along wiring runs to accommodate vibration effects.
All connections on the EFIS female 25-pin harness are described in the Instrument Installation
section on page 3-1.
Power Requirements
22 AWG wire is normally sufficient for the power supply and ground lines, but we recommend
that you consult a wire sizing chart and determine the size required for the wire routing in your
particular aircraft. Ensure that the power lines include a circuit breaker or an appropriately sized
fuse for the wire you select. Power is fed to the EFIS-D60 via pins in the female D-25 connector
as shown on the 25-Pin Female EFIS Harness diagram on page 2-2.
The EFIS-D60 system-wide power requirement is 12 watts typical and 17 watts maximum. On a
12-volt system, this translates to about 1.5 amps of maximum current draw. On a 24-volt system,
this translates to about 0.75 amps maximum current draw. Normally, a 3-amp circuit breaker or
fuse is sufficient.

3. INSTRUMENT INSTALLATION
This section provides you with the information needed to physically and electrically install the
EFIS-D60.
Selecting a Remote Compass Module Location
Finding a good location for the EDC-D10A
remote compass module is critical to an
accurate EFIS-D60 heading display. Keep in
mind that calibration can compensate for
small static magnetic fields superimposed
upon the earth’s field; it cannot take
into account dynamic effects like
AC currents, non-constant DC
currents and non-stationary ferrous
material (e.g., an electric turn
coordinator). Use the following
suggestions to help you find a goo
location for yod ur EDC-D10A.
• Keep the EDC-D10A away from
any source of magnetic fields
(such as electrical equipment and currentcarrying wires) and ferrous material.
• Move a handheld compass throughout the
space surrounding your location to get a r
idea of the suitability of your chosen location
If the needle deviates significantly from
magnetic north in any given area, that locatio
would not be ideal for the EDC-D10A.
• The ED
the aircraft (away from magnetic interference)
such that its pitch is as close to that of the
EFIS-D60 as possible. It does not need to b
directly along any axis of the EFIS-D60. It
should be mounted with the long axis
parallel to the wings, the electrical
connector facing toward the front of the
plane, and the mounting tabs on the bottom.
The bracket used to hold the EDC-D10A
must hold the EDC-D10A at the same pitc
roll, and yaw as the EFIS-D60 with respect
to the airframe. We recommend that you use
an electronic level, if available, to make
sure the EDC-D10A is aligned with the
EFIS-D60 to better than 1 degree.

• All mounting hardware needs to be made from non-ferrous material such as aluminum,
plastic, or brass. Many stainless steel screws are magnetic. If the item is attracted to a
magnet, it should not be used in the installation. The EDC-D10A needs to be mounted
location as free from magnetic interference as possible. This means keeping the EDC-D10A
away from any ferrous nuts, bolts, and screws, aircraft tubing, as well as from wires or
devices carrying any appreciable current such as strobe light wiring, autopilot servos, or
other electronics.

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 downloads.dynonavionics.com.
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.

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.
3-4 EFIS-D60 Installation Guide
Page 17
Instrument Installation
Also, do not have your EFIS-D60 plugged into the USB-to-Serial adapter while installing the
driver.
Altitude Encoder Wiring
The EFIS-D60 outputs its altitude
measurements in one of four standard serial
outputs and is readable by many modern
transponders. The EFIS-D60 will function
properly whether or not this altitude encoder
functionality is used. To use the EFIS-D60‘s
altitude encoder functionality, simply wire
the 2 encoder connections (GND and
Encoder Transmit) from the DB25 connector to their
respective connections on your transponder.
Per ATC/FAA requirements, the serial encoder output
of the EFIS-D60 reports pressure altitude, which, by
definition, is indicated altitude when the baro is set to
29.92. So, when you set your EFIS-D60‘s baro
adjustment to 29.92, its indicated altitude will match
the altitude that is being reported to your transponder.
There are four different serial formats used by
transponders. The EFIS-D60 can output any of these
formats. To select which format the EFIS-D60 sends out its serial encoder output port, you must
choose the appropriate format via the menu system. When the menu system is displayed, push
the following sequence of buttons: SETUP > ALTENC. When in the Altitude Encoder Setup
menu, you can toggle the resolution of the output between 10 and 100 feet; this accommodates
some transponders which can input and display altitude in 10 foot increments. In this menu, you
can also select between the four different output formats, which are described below.
If your transponder requires parallel Gray
code input, and you wish to use the EFIS-D60
as your altitude encoder, you will need to
purchase Dynon Avionics’ Encoder Serial-toParallel Converter. Please refer to page 5-13
for more information on the installation of
this option.

the instrument and tray extend about 4.5” behind the panel, and the supplied harness extends
three inches more. Use the dimensions (in inches) found on the diagram to plan for the space
required by the instrument. Take the following considerations into account when selecting a
mounting location for the EFIS-D60.
Avoid placing the instrument near heater vents or any source of extremely hot or cold air. Keep
in mind that the air surrounding the EFIS-D60 during operation may be no warmer than 50 °C.
Plan a panel location that allows convenient viewing of the instrument with no obstruction.
When flying straight and level, the panel angle from vertical may not be greater than +/- 30
degrees. The unit must be aligned as close as possible with the longitudinal and lateral axes of
the aircraft. The firmware supports an adjustment for panel tilt, but not for mounting errors in
yaw or roll. Correct attitude performance depends on mounting the EFIS-D60 square with the
direction of flight.
To mount the EFIS-D60, you must make a rectangular cutout in your panel. Ensure that the
dimensions of the cutout are: 6.780” wide and 4.750” tall. Place the D100-series mounting tray
behind the cutout. Secure it to your panel in whatever way you desire. Riveting it to the panel is
ideal, but drilling holes for mounting screws and nuts will work as well. You may cut off 2
horizontal or vertical tabs from the mounting tray to minimize the space taken up behind the
panel. Upon securing the mounting rack to the back of your panel, slide the EFIS-D60 into it.
Use the included 7/64” Allen wrench to secure the mounting screw (at the bottom left of the
front bezel) into mounting rack. At your discretion, you can also screw a #6-32 screw into the
back of the mounting rack on the opposite side. This screw should penetrate into the instrument
no further than ¼”.

Instrument Installation
Connecting Static & Pitot Lines
The AOA, pitot, and static ports on the back of the
EFIS-D60 are equipped with 1/8” NPT Female
fittings. To attach your pitot and static lines to the
back of the EFIS-D60, you must use standard 1/8”
NPT Male fittings at the end of each of the lines.
To install, simply connect your static and pitot
sources to the EFIS-D60. T’ing off of existing lines
is acceptable if performing a retrofit or connecting
in parallel with other instruments. View the
following back view diagram the placement of your pressure lines.
Use a wrench to secure the mating pressure line fittings to the corresponding locations on the
back of the EFIS-D60. Do not over-tighten.
If you purchased Dynon’s AOA pitot tube, note that it has pitot and AOA ports on it, but not
static. You will need to provide your own source of static pressure for the EFIS-D60 and any
other instrument in your panel which requires it.
The EFIS-D60’s attitude calculation
requires either airspeed (from pitot
and static) or GPS data. To ensure
proper operation, at least one of these
data sources must be available. We
recommend the EFIS-D60 be
connected to pitot and static systems
in all installations.

4. EFIS CALIBRATION AND CONFIGURATION
During manufacture, your EFIS-D60 underwent a comprehensive calibration, verification, and
burn-in routine that minimizes setup time and ensures that your EFIS-D60 meets Dynon’s
stringent performance specifications. To account for your individual preferences and your
aircraft’s particular setup, there are a few simple calibration and configuration steps that you
must complete before using your EFIS-D60. This section takes you through these steps to make
sure that you have properly installed and configured your EFIS-D60.
CAUTION: It is your responsibility to fly your plane safely while performing any
configuration or calibration in flight. The best scenario would include a second person to
perform any necessary steps on the unit.
Ensuring Proper Installation
Turn your unit on by energizing the aircraft power to which it is connected. Ensure that the
screen is bright and readable and that all instrument displays appear. If a desired display item is
not present, refer to the User’s Guide to use the CLUTTR feature to display the missing item.
Setting Zero Pitch (In flight)
For the purposes of this setting, level is defined as the attitude at which the aircraft’s
longitudinal axis is parallel to the ground. For most aircraft, the attitude the aircraft
assumes at normal cruise speeds will be acceptable. Additionally, this feature should not
be used to “zero out” pitch when the aircraft is at an attitude other than level. Do not
think of this adjustment as you would the parallax adjustment on a normal attitude
indicator. Instead, think of it as a calibration step which is not changed often.
With your aircraft flying straight and level, enter the SETUP > PITCH menu. Press INC or DEC
until the horizon line intersects the center of the crosshairs. It is important that this be done while
the aircraft is level to ensure proper pitch and roll display throughout all maneuvers.
Compass Heading Calibration
This section guides you through the calibration and configuration of your magnetic heading
indication. Prior to calibrating your EDC-D10A, you must configure the local magnetic
inclination and magnetic intensity as described in the sections below.
SETTING MAGNETIC INCLINATION ANGLE AND INTENSITY (REQUIRED)
To calibrate your EFIS-D60 heading, you must input your location’s current magnetic
inclination angle and intensity. Before doing this, you must obtain these two values for
the geographic location where you will be performing the calibration. Note that this
procedure only needs to be done once, prior to magnetic calibration. Moving the aircraft
to another location does not require repeating this procedure.
EFIS-D60 Installation Guide 4-1
Page 24
EFIS Calibration and Configuration
Obtaining Magnetic Inclination and Intensity
1. Browse to web page: www.dynonavionics.com/docs/maginfo.html. (Looking up this
information does not have to be done on a computer at the plane, with live Internet
access.)
2. The Dynon Avionics “Magnetic Inclination and Intensity” web page is updated as
needed; it contains a link to a NOAA web pages and instructions for easily finding your
local magnetic inclination and intensity by inputting your ZIP code (in the US) or your
latitude and longitude and inputting the resulting data into your Dynon EFIS.
3. Follow the instructions listed on the web page, especially clicking the “Compute
Magnetic Field Values” button at the bottom of the linked page – the values required by
your Dynon EFIS will be displayed only after clicking that button.
Entering inclination and intensity into the EFIS-D60
1. Enter the inclination setup menu by pressing any button beneath an EFIS page (except the
far left or far right hotkeys), then SETUP > MAGINC
2. Press INC or DEC to increment or decrement the displayed inclination angle. Press and
hold to change values more rapidly.
3. When the display shows the magnetic inclination angle for your location, press BACK to
leave the menu.
4. Enter the magnetic intensity setup menu by pressing any button beneath an EFIS page
(except the far left or far right hotkeys), then SETUP > MAGINT
5. Press SEL to change the digit being incremented or decremented. Press INC or DEC to
increment or decrement the selected digit. Press and hold to change values more rapidly.
6. When the display shows the magnetic intensity for your location, press BACK to leave
the menu.

EFIS Calibration and Configuration
EDC-D10A HEADING CALIBRATION (ON GROUND ONLY)
The procedure for in-plane calibration of the EDC-D10A involves pointing the aircraft in four
directions and taking data at each direction using the EFIS-D60. The EFIS-D60 will then
perform some calculations to ensure an accurate calibration.
If you attempt a magnetic caibration without having performed the preceding section
(Setting Magnetic Inclination Angle and Intensity), a warning message will be displayed:
WARNING: MAGNETIC INCLINATION NOT SET.
During magnetic calibration, do not turn the power off on the EFIS-D60. This will cause
any recorded compass calibration data to be lost; the calibration will need to be restarted.
To perform the calibration, you will need the following:
1. EFIS-D60 and EDC-D10A installed in aircraft.
2. Magnetic inclination angle and intensity properly entered into the EFIS-D60 per the
section above.
3. An accurate method of aligning the aircraft with magnetic North, East, South, and West,
such as an airport’s compass rose.
Once you have the installation completed, have verified that your EDC-D10A communicates
with the EFIS-D60 (i.e., you see the heading tape displayed on the EFIS main page), and have
located a suitable place to perform the calibration, perform the following steps:
1. Turn on the EFIS-D60 and allow it to warm up for at least 15 minutes before performing
the calibration.
2. Align the aircraft pointing magnetic North as closely as possible.
3. On the EFIS-D60, enter the menu system by pressing any button beneath an EFIS page
(except the far left or far right hotkeys) and press SETUP > MAGCAL. You should see a
menu that reads NORTH, EAST, SOUTH, and WEST. If you do not, then the EDCD10A is not properly communicating with your EFIS-D60.
4. Press the NORTH button; you will see the message, COLLECTING DATA FOR
NORTH along with a 15 second timer. Let the time run out before proceeding.
5. Align the aircraft pointing magnetic East as closely as possible.
6. Press the EAST button; you will see the message, COLLECTING DATA FOR EAST
along with a 15 second timer. Let the time run out before proceeding.
7. Align the aircraft pointing magnetic South as closely as possible.
8. Press the SOUTH button; you will see the message, COLLECTING DATA FOR
SOUTH along with a 15 second timer. Let the time run out before proceeding.
9. Align the aircraft pointing magnetic West as closely as possible.
10. Press the WEST button; you will see the message, COLLECTING DATA FOR WEST
along with a 15 second timer. Let the time run out before proceeding.
11. Press the END button. This will cause the EFIS-D60 to pause as it calculates. This pause
should last between 1-20 seconds. However, if the collected data is poor, this can take as
EFIS-D60 Installation Guide 4-3
Page 26
EFIS Calibration and Configuration
long as 5 minutes. A message will be displayed onscreen: CALCULATING MAGNETIC
CALIBRATION VALUES.
12. Wait for the message CALIBRATION COMPLETE before attempting to use the EFIS-
D60 or remove power. Press BACK to leave the menu.
This completes the EDC-D10A calibration process. The process can be repeated as often as
desired. The overall accuracy of the compass depends on the installation location (away from
any ferrous materials or current carrying wires or devices), the installation alignment (aligned
with the EFIS-D60 in pitch, roll, and yaw), and the calibration procedure (accurately aligning the
aircraft with North, East, West, and South and having the correct magnetic inclination angle
loaded into the EFIS-D60). If the compass performance is not adequate for your usage, we
suggest that you investigate each of these factors and try to optimize your installation for each
factor.
If the heading shown onscreen is off by a small, but constant amount, you can change a heading
offset in the EFIS-D60 which will correct this. Orient your plane in a known direction,
preferably on a compass rose at the airport. Navigate to the Heading Adjustment menu by
pressing SETUP > MAGADJ. Increment or decrement the value of the heading offset until the
EFIS-D60 heading corresponds to the direction in which your plane is pointed.
Configure Airspeed Color Thresholds
To configure the airspeed bar color thresholds for your unit enter the SETUP > IASCLR menu.
This displays the Airpseed Color Threshold menu. In this menu, enter the values for five
airspeed constants (Vso, Vs1, Vfe, Vno, and Vne), each of which has its own button. Enter these
values in units of knots, mph, or km/h depending on what airspeed units you are currently using
(you may change the displayed airspeed units via SETUP > UNITS > IAS).
Perform the following steps for each airspeed constant:
1. Press SEL to select the digit you wish to increment or decrement.
2. Press DEC- or INC+ to decrement or increment the selected digit.
3. Press BACK to return to the previous menu.
You will not be able to see some of the colors until the aircraft has achieved airspeeds in
the range of each threshold

The appendices contain additional information pertaining to the installation and maintenance of
the EFIS-D60. You will find here a table of weights, specifications, a configuration table, the
maintenance manual, the AOA Pitot Installation Guide, and the Encoder Serial To Gray Code
Converter Installation Guide.
Appendix A: Instructions for Continued Airworthiness
INTRODUCTION
This section gives the installer or mechanic information pertaining to maintenance of the EFISD60. Additionally, it provides the steps necessary to ensure continued airworthiness for the unit.
CAUTION
With the exception of replacing the Internal Backup Battery, the EFIS-D60 contains no userserviceable parts. Refer all servicing to Dynon Avionics.
INSTRUCTIONS FOR CONTINUED AIRWORTHINESS
Other than for regulatory periodic checks and an annual Internal Backup Battery capacity test (if
optional Internal Backup Battery is installed), maintenance of the EFIS-D60 is “on-condition”
only. With the exception of the Internal Backup Battery, periodic maintenance of the EFIS-D60
is not required.
ALTIMETER CHECK
The following test can be performed on an as-needed basis. If the altimeter is found to be out of
specification, the following single-point adjustment can be performed by navigating the menus to
SETUP > ALTADJ. In the Altimeter Adjustment menu, you can change the displayed altitude by
up to 500 feet up or down. After making this adjustment, ensure that the altimeter on the EFISD60 meets the tolerances allowed between 0 and 30,000 feet. If this adjustment does not bring
the altimeter on the EFIS-D60 to within specification at all attitudes, please contact Dynon
Avionics to return for service.
INTERNAL BACKUP BATTERY CHECK
If your EFIS-D60 has a rechargeable Internal Backup Battery, it is necessary to ensure that the
battery capacity is such that it will last at least 2 hours on a full charge. At least once per year,
perform the following test.
1. With the EFIS-D60 drawing power from an external source, allow it to charge its Internal
Backup Battery above 16.0 volts. Observe the voltmeter (to display, use SETUP >
CLUTTR > VMETER). The battery may charge to as high as 16.8 volts, but it is only
necessary to charge it to 16.0 volts for this test.
2. Remove all sources of external power from the EFIS-D60, ensuring that it is operating
off its Internal Backup Battery.
EFIS-D60 Installation Guide 5-1
Page 28
Appendix
3. Ensure that the screen is at its full brightness level. To do this, enter the menu system by
pressing any button and press DIM and increase the brightness until it will not increase
anymore.
4. Let the unit remain on for 2 hours.
5. If, after these 2 hours, your EFIS-D60 has not turned off and does not display the
INTERNAL BATTERY LOW warning, the Internal Backup Battery passes the capacity
test.
6. Make sure you recharge your battery; a full charge is reached when the voltmeter shows
at least 16.0 volts on the Internal Backup Battery.
If your Internal Backup Battery does not pass the above test, please contact Dynon Avionics and
refer to Appendix E for instructions on how to replace the Internal Backup Battery.
FIRMWARE UPGRADE
Dynon Avionics provides free firmware updates for all its products, and continues to add new
features periodically. We suggest that you regularly ensure that your EFIS-D60 has the latest
firmware by visiting our website at downloads.dynonavionics.com and downloading the latest
Dynon Product Support Program. This software contains the latest firmware updates for all
Dynon products.
The EFIS-D60 is upgraded by connecting a PC to the EFIS-D60’s serial port and starting the
Dynon Support Program on the PC.
DISPLAYED ALERT MESSAGES
The following table describes the alert messages that the EFIS-D60 can display.
Alert Message Description End condition
INTERNAL
ERROR
SERVICE UNIT
This error can occur for a few
reasons, including an aborted upload.
It signifies that the EFIS-D60 has
detected internal problems in its
firmware or calibration tables.
When this error appears, it may be
possible to recover your unit in the
field. The best way of ensuring this
is to call Dynon Avionics
immediately. However, there is a
good possibility that the unit will
have to be returned for service.

Appendix
Alert Message Description End condition
ATTITUDE
RECOVERING…
TEMPERATURE
UNSTABLE
TEMPERATURE
OUT OF SPEC
This alert is displayed anytime the
unit is rotated at a rate faster than
150 degrees/second or the unit is
powered on with airspeed applied.
Rotating the unit faster than this
threshold will saturate the gyros,
leading to potentially erroneous
display. The blue/brown horizon
indication will turn grey and black to
indicate that the artificial horizon is
not currently a trusted source. Note
that this alert only appears when
airspeed is non-zero; using the EFISD60 on the bench will not trigger this
alert.
When the unit is turned on after
having been off for a long period, its
internal temperature will rise above
ambient at a fast rate. This fast
change in temperature can sometimes
reduce the reliability of the output of
the sensors. Therefore, this alert is
displayed and the horizon indication
is changed from blue/brown to
grey/black.
The temperature inside the unit is
outside of -30ºC to 50ºC.
The grey/black horizon indication
and onscreen message will remain
until the unit has resumed normal
operation. In the case of rotation
rate greater than 150
degrees/second, the unit enters a fast
recovery mode and usually recovers
within 5 seconds of coordinated
flight.
The screen remains normal color,
but the message is displayed until
the temperature within the unit has
stabilized. This temperature
instability should last no longer than
2 minutes. For this reason, it is a
good idea to turn the unit on before
you run through any of the preflight
procedures, so that it will be ready
by the time you are ready to fly.
The screen remains normal color,
but the message is displayed until
the temperature within the unit is
within the specified range. This is
most common in unventilated
panels during hot periods. If you
continue to see this alert, provide
more airflow to the space around the
EFIS-D60.

Appendix
Alert Message Description End condition
INTERNAL
BATTERY LOW
You will see this alert only when
operating the unit solely off the
internal backup battery. When its
voltage has dropped below a certain
threshold, you will see this alert.
Additionally, the voltmeter will be
displayed onscreen. When you see
this alert, it is advisable that you turn
the unit off by pressing the POWER
button in Main Menu 1.
The alert will disappear when you
press any button; however, it is
advised that you do not ignore this
alert, as it appears when the unit’s
internal battery has very little life
left. This alert will also go away
upon the application of either the
external backup battery or Master
Power. At that point, the battery will
begin charging off the external
power.
REMOTE
COMPASS NOT
DETECTED
The EFIS-D60 is unable to
communicate with the EDC-D10A.
If you have an OAT connected to
your EDC-D10A, you will lose this
reading, as well.
Ensure that you a) have an EDCD10A installed and b) have verified
that the wiring to the EDC-D10A is
correct. Please see the EFIS-D60
Installation Guide for more
information on verifying the
installation of the EDC-D10A.
This error also can appear if you
have updated the firmware in your
EFIS-D60 while the remote
compass was not connected. If this
is the case, try uploading the new
firmware again with the EDC-D10A
connected. Attempt the connection
within the first few seconds of
operation.
Note that the EFIS-D60 does not
have internal magnetic sensors and
thus requires the EDC-D10A be
connected.
OAT SENSOR
NOT
DETECTED
This alert appears when the EFIS has
an OAT connected and then loses
that connection for some reason.
Double-check your wiring between
the EFIS-D60 and the EDC-D10A
as well as that of the OAT sensor.
Either the EDC-D10A has become
disconnected, or the OAT sensor
itself has become disconnected from
the EDC-D10A.

of your plane. If you need to adjust by more than 200 ft, or
find that you need to adjust frequently (after setting your
baro), please contact Dynon Technical Support for
assistance.
You may recalibrate your EFIS-D60‘s zero pressure value.
With your plane in as windless an environment as possible
(e.g., a hangar), cover both the pitot and static ports with a
sock or cloth to minimize airflow without putting pressure
on the ports. Next, on the EFIS-D60, enter the EFIS main
menu, press SETUP > SPDCAL. When you are confident
that there is no pressure on the pitot and static ports, press
either button corresponding to SET ZERO PRESSURE.
Press YES to confirm you have zero pressure on the pitot
and static ports. You will see a message indicating that the
unit is calibrating. This should only take a few seconds. On
your next flight, verify that the airspeed is what you expect.
To reset the airspeed calibration to factory defaults, enter the
SPDCAL menu, and press RESET DFLTS.
Ensure that your power supply is capable of supplying at
least 2 amps and that it is at least 10 volts.
If, after verifying that you have met these two conditions the
unit does not operate normally, it is necessary to contact
Dynon Avionics.
Verify Master Switch Power is connected.

INSTRUCTIONS FOR RETURN
If none of the above sections have helped resolve an ongoing issue with your EFIS-D60, please
contact Dynon Avionics to discuss the issue with Technical Support. If, after troubleshooting
with a Dynon representative, the issue cannot be resolved, we will provide you with a Return
Material Authorization (RMA) number to use when shipping the EFIS-D60 to us. If your unit is
still under warranty, the repairs will be performed and the EFIS-D60 will be returned promptly.
If your warranty has expired, the Dynon representative will make arrangements with you and
make you fully aware of the costs before proceeding with the repair.
We recommend that you also send your EDC-D10A remote compass along with your EFIS-D60.
This ensures that if we upgrade the firmware in your EFIS-D60, the EDC-D10A will have
corresponding firmware.
While Dynon Avionics makes every effort to save and restore your unit’s settings and
calibrations, we cannot guarantee that this will happen. Please note that after you receive your
unit back from Dynon Avionics with a factory calibration, the heading display on the EFIS-D60
may be inaccurate once re-installed in your aircraft. If this is the case, you will have to perform
the magnetic calibration again. When you receive your EFIS-D60, it may have newer firmware
installed on it than it did when you sent it in. Check downloads.dynonavionics.com for
information on what’s new.

Appendix B: Dynon AOA/Pitot Installation and Calibration
Thank you for your purchase of Dynon’s AOA/Pitot Probe. This guide walks you through the
steps to install and calibrate both the heated and unheated versions of the AOA/Pitot Probe.
While the probe senses standard pitot pressure, allowing it to work with any standard airspeed
indicator, its AOA functionality is designed specifically to work with Dynon’s EFIS series of
products. Do not expect it to work properly with another AOA system.
To ensure accuracy, it is very important that you install the probe correctly and perform the
specified calibration steps. We recommend that you read the entire guide before proceeding with
the installation.
Dynon’s Heated AOA/Pitot Probe is nickel-plated. Do not polish the probe as this will cause the
finish to come off.
AOA CALCULATION: PRINCIPLES OF OPERATION
Dynon Avionics’ AOA/Pitot probe performs two functions: airspeed sensing and angle of attack
sensing. These functions require two pressure ports on the tip of the probe. The normal pitot
pressure port is on the front face of the probe and is designed to be insensitive to angle of attack.
The second pressure port is located on an angled surface just under the pitot port and is designed
to be very sensitive to AOA. The EFIS-D60 then uses the difference between these two pressures
to calculate the current angle of attack.
HEATING: PRINCIPLES OF OPERATION
The heated version of Dynon’s AOA/Pitot Probe utilizes a heating mechanism unlike any other
heated pitot on the market. The probe is heated by a high-quality nichrome heating element
whose temperature is accurately measured and regulated by the heater controller. This controller
– located in an enclosure which can be mounted in a wing or elsewhere – regulates the heat at the
tip of the probe to a constant temperature. There are several advantages to this, including: lower
power consumption, increased heating element lifespan, and a much cooler pitot on the ground
when de-icing is not necessary. This unique technique ensures that the pitot can be rapidly deiced when required, but does not needlessly waste electricity when not in icing conditions.
While the probe does not operate like a normal heated pitot, it will still get fairly hot in normal
ambient temperatures. When turned on, it will regulate its internal temperature to about 70°C to
80°C. To ensure that the heater is working, briefly touch the end of the pitot farthest from the
snout after 1 minute of operation and verify that it is warm.
FAILURE WARNING
Designed to meet the indication requirements of FAR 23.1326, the heated pitot controller has an
output that can trigger a warning light in the cockpit whenever the probe heater is turned off or is
not functioning properly. While not required for Experimental and LSA category aircraft, this
feature provides peace of mind, giving you instant feedback that your probe’s heater is working
as designed.
TOOLS AND MATERIALS REQUIRED
• Dynon Avionics AOA/Pitot probe.
EFIS-D60 Installation Guide 5-7
Page 34
Appendix
• Two plumbing lines (usually ¼” soft aluminum or plastic tubing) routed from the EFIS-D60
to the probe mounting location.
• Adapters to interface with the 3/16” aluminum tubing from the probe to whatever plumbing
lines are installed in the aircraft (AN919-2D for 3/16 to ¼ , AN819-4D sleeve AN818-4D
nut, AN819-3D sleeve, and AN818-3D nut)
• #36 Drill and 6-32 tap
• AOA Pitot Mounting bracket. Models known to work well include:
o Gretz Aero CBK12 (Chrome) and PBK12 (Paintable), available at
www.gretzaero.com/mountbracket.html or from Aircraft Spruce.
o SafeAir1 also makes a bracket with a joggled lip for the RV series. It is available
from www.safeair1.com.
Please follow these instructions explicitly as improper installation can result in permanent
damage to your device and/or aircraft.
HEATER CONTROLLER WIRING AND MOUNTING
If you have purchased the heated version of the probe, please follow the instructions in this
section. If you have purchased the unheated version of the probe, you may skip to the AOA/Pitot
Probe Mounting section on page 5-11. Please follow these instructions explicitly as improper
installation can result in permanent damage to your device and/or aircraft.
Heater Controller Mounting
The heater controller box should ideally be mounted close to the AOA/Pitot Probe. The box’s
dimensions are found at right, for
reference. When mounting the
controller close to the probe, ensure
that it is close enough for its wires to
mate with the probe’s wires, with
room for strain-relief. If you find it
difficult to mount the controller in
the wing, or simply wish for the
controller to be mounted closer to
the battery, you must extend the
lines using the correct wire gauge as
described in the Wiring section
below.
When the desired location is
selected, secure the heater controller
via the 4 mounting holes. Route the
wiring between the probe, controller, panel, and power source, as described below.
Heated AOA/Pitot Wiring System Overview
The following block diagram depicts the basic layout of the electrical connections between the
probe and heater controller. This diagram should be used in conjunction with detailed

probe can be connected without extension. The
three mating pairs of colored wires – terminated with Fastons – are used to carry the current to
the heating element in the probe. The 2 white wires are for temperature measurement, and can
thus be small. If you have mounted the heater controller near the probe and do not need to extend
the wires between the two, simply plug each wire on the controller into its corresponding likecolored wire from the probe.
If you do need to extend the wires between the probe and the controller, use the recommended
wire size (see chart on page 5-8) for your run length. Since extending the wire runs requires that
you cut the connectors off the 5 wires between the probe and controller, splice the extension
wires between the probe and controller using butt splices or other similarly secure method. The
white wires are not polarity-dependant. Additionally, as the white wires do not carry any
significant current, you may extend them with 26 AWG or larger for any run length.
Controller Power wiring
Three wires – colored red, black, and white
– exit the controller for connection to your
electrical system. Power (between 10 and
15 volts) is fed to the controller via the red
and black wires. The maximum current
draw of the heated pitot controller/probe is
10 amps. You must route your own
appropriately-sized wires to where the
heater controller is mounted. Both power
and ground lines should be able to handle
10 amps with minimal voltage drop, as
recommended in the chart on page 5-8.
The red wire should be connected through
a pilot-accessible switch to the main power
source in the aircraft (limited to 15 volts).
The switch allows you to manually turn the
heater controller on and off, depending on
the situation. Install a 15-amp fuse at any
point along the power line to the heater
Color Notes
Red Connected through a pilot-accessible
switch to 10–15V supply. Must handle
up to 10 amps.
Black Must have a constant connection to
ground. This is required for the warning
light to operate when controller is
powered off or not functioning. Line
must handle up to 10 amps.
White Connected to a light bulb (or resistor &
LED) tied to switched ship’s power.
This line is grounded when the heater
controller is powered off or not
functioning. Connection can handle no
more than 1 amp. Current depends on
light source connected.

controller. Remember that even when the controller is powered on, it only heats the probe the
amount necessary to maintain temperature.
The black wire should be permanently connected to ground. Cutting power to the heater
controller should occur via the red power line, not the black ground line.
Heater Status Connection
Note: The probe heater functions properly whether or not you make this connection. It is simply
a status output for your convenience.
The white heater status wire is grounded when the probe heater is turned off or not functioning
properly. This wire should be connected to a light on the panel, whose other terminal is
connected to switched aircraft power. When the heater is on and functioning properly, the white
heater status line is open, leaving the indicator light turned off. When there is no power to the
heater controller – or it is not functioning properly – the white line is grounded, turning the
indicator light on.
Aircraft Spruce P/N 17-410 is an example of a light that will work for this application. An LED
and resistor in series will also suffice. If you use an LED as the indicator, you must choose a
resistor that delivers the appropriate current to the LED, and can accommodate the power
required for its current and voltage drop.
If you own a Dynon EMS-based product, you may also use one of its two contact input to
display an onscreen indication. Connect this heater status output directly to the desired EMS
contact input, with no additional resistors or lights. You must configure the contact display as
described in your EMS-based product’s Installation Guide.
AOA/PITOT PROBE MOUNTING
The Dynon Avionics AOA/Pitot probe has been designed as an under-wing pitot. The following
information applies to this type of installation. If you wish to mount your pitot on nose boom
mount, contact us so we can make the appropriate adjustments to your pitot. The heated version
of Dynon’s AOA/Pitot Probe does not come in a boom-mount configuration.
AOA/Pitot Probe Mount Location
The Dynon Avionics AOA/Pitot probe only functions correctly when mounted in a location
where the airflow over the probe is relatively undisturbed by the aircraft. In general, we
recommend that you mount it at least 6 inches below the wing and with the tip of the probe
between 2 and 12 inches behind the leading edge of the wing. Typically, pitot probes are
mounted about mid-wing span wise to minimize the effects of both the propeller and the wing
tips. Testing during the probe development has shown that the standard mounting locations for
the pitot probe in the RV series of aircraft also works for the Dynon probe.
AOA/Pitot Probe Mounting Instructions
After the mounting location has been determined, mount the pitot mounting kit per the included
instructions or fabricate your own mount. In either case, mount the probe securely to the wing
such that the body of the probe is horizontal during level flight. Drill and tap mounting holes (#6-
32) on the probe to match your mounting bracket. Use caution when drilling the holes, ensuring
that you avoid drilling into the pitot and AOA pressure lines. As long as you do not penetrate
EFIS-D60 Installation Guide 5-11

Appendix
these lines, you may drill all the way through the outer metal without affecting the probe’s
waterproofing.

PLUMBING
NOTE: Because the pitot and AOA plumbing tubes have not been annealed, they work-harden
rapidly when manipulated. Make gentle bends, and only bend any given section once.
After mounting the probe, route the pitot and AOA lines from the probe to your EFIS-D60. The
tube closest to the snout is the pitot line, while the tube in the rear is the AOA line. There is no
static source on the probe.
After mounting the probe, install adapters to connect the 3/16 plumbing lines from the probe to
whatever plumbing lines run back to the EFIS-D60 in your aircraft (AN 919-2D for 3/16 to ¼).
We strongly recommend using aircraft grade fittings such as standard AN fittings. Make sure the
plumbing lines do not chafe or interfere with any aircraft control systems.
PRESSURE CHECK
Dynon’s pitot design deliberately has a pin-sized leak hole in each of the two tubes to permit
draining any moisture which might accumulate inside. These holes are located in the middle of
the tube at the bottom. Plugging these holes does not guarantee a pneumatic seal (although one is
sometimes present). The leak that may exist does not affect the performance of the probe. You
will, however, need to take it into account when doing pressure/leak tests on your pitot system
CALIBRATION
CAUTION: It is your responsibility to fly your plane safely while performing any
configuration or calibration in flight. The best scenario would include a second person to
perform any necessary steps on the EFIS-D60.
Once you are flying straight and level at a safe altitude for stalls, enter the SETUP > AOACAL
menu. While the AOACAL menu is displayed, oscillate the aircraft between ± 5° pitch 4 times at
fast cruise airspeed. During this maneuver the EFIS-D60 records the lowest angle of attack that
you usually see during flight. You do not need to push any additional buttons before starting this
maneuver.
Refer to the list below of the stalls recommended to complete the user calibration. The general
idea is to record stall data to find the lowest angle of attack stall. The list we have suggested is a
starting point and produces a good calibration under most circumstances. However, if there are
EFIS-D60 Installation Guide 5-13
Page 40
Appendix
flight regimes not listed that you suspect would create stalls at lower angle of attack it would be
good to record those as well.
With full power, no flaps
With no power, no flaps
With full power, full flaps
With no power, full flaps
Push the STALL button before performing each stall. When you push the STALL button, a 45second timer starts. Notice the “T” next to the time that is counting down. During the 45 seconds
that the timer is counting down, you are expected to have completed the stall maneuver. If any
stall maneuver is not completed before the timer expires, the calibration will be invalid, and
should be reset. To do this, push the CANCEL button. This exits the AOACAL menu; re-enter it
to begin the calibration again. After completing the stall, make sure you let the 45 second
timer count down to 0 before you push the STALL button for the next stall.
When the listed stall maneuvers have been completed according to the above procedure, push
FINISH. At this point, the AOA indicator has been calibrated. If it is not visible, turn the display
on in the SETUP > CLUTTR > AOABAR menu. This calibration should result in the lowest
angle of attack stall occurring just above the red/yellow boundary. If this is not the case, please
repeat the AOA user calibration, including flight configurations that resulted in stalls with
incorrect indications. If the user calibration continues to be unsuccessful, please contact Dynon
Avionics technical support.
ALARM SETUP
Enter the SETUP > AOAALM menu and press any of the buttons beneath the AUDIO label to
select the point on the AOA bar at which you wish the alarm to sound:
AUDIO: ALWAYS OFF
AUDIO: ON IN RED
AUDIO: START YLW TOP
AUDIO: START YLW MID
AUDIO: START YLW BTM
The latter three alarms (the ones that begin with START) are progressive, meaning the audio
alert gets more intense as your angle of attack increases. You may set these progressive alarms to
start at the top, middle, or bottom of the yellow section of the AOA bar. Setting AUDIO to ON
IN RED configures an intense alarm to occur only when the AOA indicator is in the red.
To reduce nuisance audible AOA alarms – such as when taxiing, taking off and landing – the
alarm can be inhibited below a selected airspeed. While in the SETUP > AOAALM menu, press
MINSPD to configure the minimum airspeed at which an AOA alarm can occur. Anytime
airspeed is below the MINSPD value, AOA alarms will not occur; anytime it is above the
MINSPD value, alarms can occur. If the AOA alarm is already sounding as airspeed falls below
this threshold, it will continue to sound until the high AOA condition is resolved.

Appendix C: Encoder Serial-to-Gray Code Converter Installation
INTRODUCTION AND DESCRIPTION
The Encoder Converter is an electronic device that receives the serial encoder data from the
EFIS-D60 and outputs standard Mode-C parallel Gray code into your Mode-C transponder. This
Encoder Converter requires data from the EFIS-D60 and is not to be confused with other
standalone encoders available on the market. While the installation is not complex, it is
important that you install the unit correctly. The Encoder Converter does not output an encoder
strobe signal.
The Encoder Converter is designed to be powered off voltages between 10 and 30 volts.
TOOLS AND EQUIPMENT
The following parts are not included with your Encoder Converter purchase but may be
necessary to complete the installation.
• Wire cutters
• Connector crimp tool
• Crimp pins
• 25-pin EFIS harness to mate with EFIS-D60 (may have been purchased with your EFIS-D60)
• Connector to mate with Gray code transponder
ELECTRICAL INSTALLATION
The following section describes the wiring requirements for using the Encoder Converter. Please
follow these instructions explicitly as improper wiring can result in permanent damage to your
unit.
RECOMMENDED WIRING PRACTICES
NOTE: Use correct splicing techniques for all electrical connections, taking care to properly
insulate any exposed wire. A short circuit between any of the wires may cause damage to the
Encoder.
The wire used in construction of your Encoder Converter is 22 gauge avionics grade Tefzel wire,
which meets Mil Standard MIL-W-22759/16.
Installing: Make sure all connections are secure and all wires are routed and strain relieved to
ensure that the wires will not chafe against any other object in the aircraft.
STEP 1: TRANSPONDER WIRING
Wire the Encoder Converter signals to their respective connections on your Mode-C transponder.
Mode-C transponder pin-outs vary from device to device. To find the correct pin-out, look at the
manual for your transponder or contact its manufacturer. The table below details which color
wire should be connected to each Transponder pin. All of the wires listed in the table leave one
end of the Encoder Converter in a single bundle. If your transponder has a switched power
output, connect this to the power inputs on the Encoder Converter. If your transponder does not
include this switched power output, the Encoder Converter power connections should be made
EFIS-D60 Installation Guide 5-15

Appendix
directly to your switched avionics power. Ensure that all avionics power is off before performing
the wiring step of this installation.
If your Altitude Transponder has either a strobe signal or a D4 pin, leave these pins unconnected.

The Gray code output of the Encoder Converter reports altitude not adjusted for barometric
pressure, as required by FAA specification. The altitude reported by the EFIS-D60 encoder will
always match the altitude shown on screen when the BARO value is set to 29.92 inHg.
STEP 2: CONNECTING TO THE EFIS-D60
Before wiring connections to the EFIS-D60 check to ensure that the wire length between your
Encoder Converter and your EFIS-D60 is appropriate. Add or remove wire length if needed or
desired. Customizing the wire length will facilitate an installation that is both cleaner and more
secure.
The only pins of interest on the EFIS-D60 connector for the Encoder Converter installation are
pins 13 and 21. The two wires exiting the Encoder Converter are the EFIS-TX and the EFISGround, which are green (or red) and black respectively, and 2 feet in length. Connect these
wires to the EFIS-D60 25-pin female harness.
Ensure that your EFIS-D60 is powered off. Then connect the black EFIS Ground wire to pin 21.
Then, connect the green wire to pin 13 (Serial Encoder Transmit) on the EFIS harness.

Appendix D: Replacing the EFIS-D60 Internal Backup Battery
1. Remove the two screws (either #1 Phillips or 7/64” hex, depending on when your unit
was manufactured) from the small, rectangular battery door on the side of the EFIS-D60.
Remove the battery door. Do not remove any other screws from the case of the unit.
2. If you previously had a battery, disconnect it from the EFIS-D60 by unplugging the
battery connector and gently pulling out old battery. It is safe to gently pull on the battery
wire to remove the battery.
3. Insert the new battery with the bumpy side up.
4. Connect the battery connector to the battery. The connector is keyed; make sure it is
positioned correctly.
5. Position the connector so it is centered on the end of the pack. Verify that the battery
pack will not interfere with insertion of either of the door screws.
6. Reinsert screws and tighten to 12 in-lbs.
