EFIS-D10A Installation Guide |
1. INTRODUCTION
This manual provides information about the physical, electrical, and plumbing installation of the EFIS-D10A, 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-D10A Pilot’s User Guide.
The EFIS-D10A 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.
OEM Installations
If your EFIS-D10A is installed by an OEM distributor, you may find that you are unable to access some menus and settings. Some Dynon distributors customize various areas of the EFISD10A firmware to maintain a consistent pilot experience and minimize integration issues across a large number of installations. Currently, OEMs can customize access levels to the following settings on Dynon systems: EMS GLOBAL setup menu, EMS SENSOR setup menu, fuel calibration, trim calibration, flaps calibration, GPS/NAV setup menu, screen configurations, data logging, and checklists/data panels. OEM distributors have the option of customizing some or all of these areas. Please contact your aircraft’s manufacturer if you have any questions about how your unit has been customized.
Warning
Dynon Avionics’ products incorporate a variety of precise, calibrated electronics. Except for replacing the optional internal backup battery in EFIS-based products per the installation guide, our products do not contain any field/user-serviceable parts. Units that have been found to have been taken apart may not be eligible for repair under warranty. Additionally, once a Dynon Avionics unit is opened up, it will require calibration and verification at our Woodinville, WA offices before it can be considered airworthy.

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-D10A 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-D10A 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-D10A. The harness is made up of 22 AWG wire and meet 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-D10A via pins in the female D-25 connector as shown on the 25-Pin Female EFIS Harness diagram on page 2-2.
The EFIS-D10A system-wide power requirement is 8 watts typical and 13 watts maximum. On a 12-volt system, this translates to about 1 amp of maximum current draw. On a 24-volt system, this translates to about 0.5 amp maximum current draw. Normally, a 2-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-D10A.
Selecting a Remote Compass Module Location
Finding a good location for the EDC-D10A remote compass module is critical to an accurate EFIS-D10A 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 good location for your EDC-D10A.
Keep the EDC-D10A away |
|
|
|
|
|
|
|
|
|
from any source of magnetic fields (such |
|
|
|
|
|
|
|
|
|
as electrical equipment and current- |
|
|
|
|
|
|
|

|
|
|
|
|
|
|
|
rough idea of the suitability of your |
|
|
|
|
|
|
|
|
|
chosen location. If the needle deviates |
|
|
|
|
|
|
|
|
|
significantly from magnetic north in any |
|
|
|
|
|
|
|
|
|
given area, that location would not be |
|
|
|
|
|
|
|
|
|
ideal for the EDC-D10A. |
|
|
|
|
|
|
|
|
|
The EDC-D10A can be mounted |
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
||
anywhere in the aircraft (away from |

possible. It does not need to be |

|
|

|
directly along any axis of the EFIS- |

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-D10A 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 in a location as free from magnetic interference as possible. This means keeping the EDCD10A 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.
EDC-D10A Communication Cable
DO NOT ATTEMPT TO POWER UP THE EFIS-D10A WITH THE EDC CABLE LEADS EXPOSED (UNSHEATHED) AND NOT INSTALLED IN THE DB9 CONNECTOR. SHORTING THESE CONNECTIONS WILL CAUSE DAMAGE TO THE UNIT.
Like the RS-232 PC Communication cable, the EDC-D10A communications cable terminates in a standard female DB9 connector. While they look similar, do not plug the EDC cable into a PC or vice versa. The following table outlines the four connections that must be made to ensure proper communication between the EFIS-D10A and the EDC-D10A remote compass module. The Dynon-supplied harness colors are listed, as well.

The EDC cable in the harness supplied by Dynon consists of 4 conductors, surrounded by a metal shield and white insulation. These 4 wires are terminated with crimped female D-sub pins wrapped in plastic tubing. If you are building your own cable, we recommend that you use shielded cable as well.
With the 25-pin EFIS harness disconnected from the EFIS-D10A, carefully cut or pull the tubing off the 4 D-sub pins.
Route the cable to the EDC-D10A mounting location chosen according to the instructions above.
Install the female pins in the correct holes on the included DB9 connector, according to the chart above. Note that Dynon has shipped harnesses with different colors for the EDC cable; determine your connections using the two sets of colors in the table above.
Install the back shell around the DB9 connector.
Correct wiring installation can be easily verified once completed. Power on the EFIS-D10A with the EDC-D10A connected to it. Observe the displayed heading and then hold one of the earpieces of a headset near the front of the EFIS-D10A. If the EDC-D10A is correctly wired, you should see no change in the displayed heading when the headset earpiece and its magnetic

speaker is near the EFIS-D10A. If you see a substantial change in heading, there is a communication problem between the EFIS-D10A and the EDC-D10A.
The metal shield around the EDC communication cable is connected to the short black/white wire emanating from the DB25. Connect this wire to ground close to the EFIS-D10A, ideally the panel.
Power Inputs
The EFIS-D10A has three separate power inputs, located on the DB25 EFIS connector. Of the three, only Master Power is required to operate the instrument. The other two inputs provide redundancy. Below is a table that explains the three inputs and their purposes. All three of these inputs share a common ground signal, wired to pin 3 on the EFIS connector.

Instrument Installation
Serial Communication Cable
More Information Is Available Online: Serial communication to non-Dynon devices, and interfacing of other devices in general can be involved and detailed. This Installation Guide is intended to provide general installation advice for the most common devices and situations. Dynon’s Documentation Wiki provides enhanced, extended, frequently updated online documentation contributed by Dynon employees and customers at wiki.dynonavionics.com.
The EFIS-D10A has one RS-232 serial port that can be used for several purposes. This serial port can only be configured for one purpose at a time.
The EFIS Serial port (DB25) is used for:
Connecting to a PC, and using the Dynon Avionics Product Support Program to perform firmware upgrades, configure checklists, and download internal logs. The Help Files of the Support Program provide detailed instructions on these functions. The latest version of the Product Support Program is available on the Dynon web site at downloads.dynonavionics.com.
Connecting serial devices such as a GPS receiver or an SL30.
“Streaming” real-time EFIS flight data to an external serial device for recording. For data formats and other information, see the Appendix in the EFIS-D10A Pilot’s User Guide. Note that for the purposes of logging data, version 5.0 of EFIS-D10A firmware added internal data logging and retrieval via the Dynon Product Support Program.
When an optional HS34 Expansion Module is connected to your Dynon DSAB network, all GPS and NAV radios must be connected to it. This simplifies the connection and usage of multiple serial devices. The HS34 also provides interfaces to non-serial devices such as those with only analog and ARINC-429 interfaces.
PC USB CONNECTION
If you do not have a serial port on your PC, you may use a USB-to-Serial adapter to connect the EFIS-D10A to your PC’s USB port. You may purchase an adapter from us, Radio Shack, or many computer stores. 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, ensure that you are connected to the Internet and do not use the driver CD; the operating system will download the correct driver. Also, do not have your EFIS-D10A plugged into the USB-to-Serial adapter while installing the driver.
EFIS SERIAL HARNESS
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

EFIS-D10A Installation Guide
Instrument Installation
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 EFIS-D10A.
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.
Read the section below that corresponds to your configuration of Dynon products. All EFISbased product configurations direct you to connect your external device to PC serial receive (pin 22) on your Dynon EFIS product. You may make this connection at any point between pin 22 on the EFIS DB25 and pin 3 on the connected DB9 EFIS/PC connector. If you purchased your harness from Dynon Avionics, it may have a yellow/green wire provided for this purpose.
IF YOU OWN ONLY AN EFIS-D10A OR EFIS-D100
Connect the GPS or SL30 transmit line into pin 22 on the DB25 connector. This is the same Serial Rx line that is used for firmware updates. You will need a way to disconnect this when you plug your EFIS into a PC for firmware updates and checklists.
If you have both a GPS unit and an SL30, you will need to wire the two transmit lines to a 3-way switch; connect the output of the switch into pin 22 on the EFIS harness. You will use this switch to toggle between GPS, SL30 and a disconnected state. The HSI auto-detects the switched instrument and will change modes automatically.
IF YOU OWN TWO EFIS-ONLY UNITS
When 2 EFIS-only units are connected via DSAB, only the DSAB Bus Master’s serial port is active.
If you have only one serial device (GPS or SL30), connect its transmit line to pin 22 on the DB25 connector of the EFIS that you have chosen to be the Bus Master. This is the same Serial Rx line that is used for firmware updates. You will need a way to disconnect this when you plug your EFIS into a PC for firmware updates and checklists.
If you have both a GPS unit and an SL30, you have two options:
Wire the 2 devices’ transmit lines to a switch, allowing you to select the serial device active on the HSI screen.
Do not connect the two EFIS units together via DSAB. You may then wire one device to one EFIS’ pin 22, and the other device to the other EFIS. Of course, the EFIS devices would be independent and unable to share GPS or SL30 data.
You will need a way to disconnect both lines when you plug your EFIS into a PC for firmware updates and checklists.
IF YOU OWN ONLY AN EMS-D10 OR EMS-D120
We recommend that you only connect a GPS to an EMS-only system; without the magnetic heading from an EFIS, the HSI page will not be functional. Connect the GPS transmit line to pin 19 on the EMS DB37 connector. This connection will give you fuel endurance information

EFIS-D10A Installation Guide |
Instrument Installation
(range, MPG, etc) on the fuel page and GPS information only (track, ground-speed, course, etc) on the HSI page. There is no need to break this connection when doing PC updates.
IF YOU OWN AN EMS AND AN EFIS (NOT FLIGHTDEK-D180)
First, ensure that your EMS and EFIS are connected as described in Dynon Smart Avionics Bus (DSAB) Wiring on page 3-11.
If you only have either the GPS or SL30 (but not both), connect the GPS or SL30 transmit line to pin 19 on the EMS DB37 connector. This is labeled “Aux Serial Receive.” With either a GPS or an SL30 connected, you are able to display an HSI on either product; with a GPS connected, you are able to display EMS fuel economy displays.
If you have a GPS and an SL30, connect the GPS to pin 19 on the EMS DB37 connector. Connect the SL30 to pin 22 on the EFIS DB25 connector. This will allow you to flip between GPS and SL30 inputs. You can use either the SL30 or GPS as the NAV source on the EFIS product. You will need to disconnect the SL30 from the EFIS when doing software updates.
IF YOU OWN ONLY A FLIGHTDEK-D180
Connect the SL30 unit to pin 22 on the EFIS DB25 connector, and the GPS to pin 19 on the EMS DB37 connector. You can display either source on the HSI using the softkeys. You will need to disconnect the SL30 from the EFIS when doing software updates.
IF YOU OWN A FLIGHTDEK-D180 AND AN EFIS
Connect the SL30 unit to pin 22 on the FlightDEK’s EFIS connector (vertical DB25) and the GPS to pin 19 on the EMS DB37 connector. You can display either source on the HSI, and you can display either on the standalone EFIS as well (provided you have connected the DSAB A & B lines from the FlightDEK-D180 to the standalone EFIS product). You will need to disconnect the SL30 from the FlightDEK-D180 when doing software updates.
Do not connect any serial devices to the secondary EFIS device. It will only display data from the serial devices connected to the master FlightDEK-D180.

Altitude Encoder Wiring
The EFIS-D10A outputs its altitude measurements in one of four standard serial outputs and is readable by many modern transponders. The EFIS-D10A will function properly whether or not this altitude encoder functionality is used. To use the EFISD10A‘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-D10A reports pressure altitude, which, by definition, is indicated altitude when the baro is set to 29.92. So, when you set your EFIS-D10A‘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-D10A can output any of these formats. To select which format the EFISD10A sends out its serial encoder output port, you must choose the appropriate format via the menu system. When the menu system is displayed, enter the MORE > SETUP > MORE > 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.
Dynon’s supplied EFIS harness has a serial altitude encoder cable which consists of 2 conductors, surrounded by a metal shield and white insulation. Dynon has shipped harnesses with different colors for Encoder serial transmit line. Determine your connections using the table at right. Connect the Encoder serial transmit to your transponder’s serial input or to Dynon’s Serial-to-Parallel Converter as described in the Encoder Serial-to-Gray Code Converter Installation section on page 7-32 in the Appendix.

EFIS Audio Alert Output |
If you have purchased and installed an HS34 and/or an AP74, we recommend that you only connect the HS34 audio output or AP74 audio output (but not both) to your audio panel. The HS34 or AP74 audio output provides voice and tone outputs for both EMSand EFIS-related alerts. When the HS34 or AP74 audio output is connected, it is not necessary to connect the audio outputs of other Dynon Avionics devices. Connecting the HS34 audio output and the AP74 audio output in parallel will result in distorted audio. Refer to the HS34 Wiring section on page 7-10 for more information.
Connect the alarm output from the EFIS-D10A to the outside terminal of a 10 kΩ variable resistor (not included). Ensure that audio outputs are connected similar to the following diagram. The 10 kΩ variable resistor can be obtained from Radio Shack (P/N 271-1715) or other electronics suppliers.

Dynon Smart Avionics Bus (DSAB) Wiring
The Dynon Smart Avionics Bus is the only way Dynon products can communicate with one another, providing features such as data sharing and alarm notification. DSAB is a multidrop bus, meaning several devices can be connected to the same 2 wires. If you have an EMS and EFIS product connected via their serial ports through a null modem, you should disconnect this legacy interface.

You must connect the DSAB A connection (pin 4) on the EFIS DB25 female harness to the DSAB A connection for the next device in the chain. Do likewise for the DSAB B connection (pin 5). Some products – like the EFIS series and the HS34 – have only one pair of DSAB connections on the back connector; other products – like the EMS series – have two pairs, for wiring convenience. If you have 3 or more devices in your system, and one of them is an EMSseries product, we recommend that you locate it in the middle of your wiring scheme as shown below. This eliminates the need to splice two wires together.
Wherever possible, ensure that the two DSAB wires (DSAB A and B) are run as a twisted pair. This minimizes the system’s susceptibility to electrical noise.
Refer to the DSAB Configuration chapter on page 5-1 for detailed instructions on configuring your DSAB network.

Panel Location and Mounting
The diagram at right shows the outside dimensions of the front bezel of the EFISD10A. Note that the instrument is about seven inches deep 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-D10A.
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-D10A during operation may be no warmer than 50
C to ensure accurate operation. 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 also be parallel to the roll axis of the aircraft (although not necessarily located along it), and have no significant roll angle in the
panel. 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-D10A square with the direction of flight.
You have two options for mounting the EFIS-D10A into your panel: standard or flush. You may use the optional flush-mount bracket, allowing the face of the EFIS-D10A to be flush with your panel. If you opted to receive the
flush mount bracket, please skip to Option 2 below. If you opted not to receive this bracket and wish to perform the standard install, follow the options in Option 1 below.
OPTION 1: NO MOUNTING BRACKET
Using this option, you will be mounting the EFIS-D10A directly into your panel. The front bezel of
3-12 |
EFIS-D10A Installation Guide |

the unit will extend beyond the plane of your panel by 0.8”.
Installation of the EFIS-D10A main unit should only be completed once all other physical and electrical installations have been performed. This will ensure that last-minute adjustments will not have to be made with the EFIS-D10A mounted in the panel.
The diagram above shows the dimensions expected for the proper installation of the EFIS-D10A into your panel using no mounting bracket. All units are in inches. Push the EFIS-D10A through the main panel hole. The four studs on the back of the EFIS-D10A will fit into the four mounting holes having dimensions listed in the diagram. Place one of the four supplied washers on each stud before pushing the EFIS-D10A into place in the panel, putting the washers in between the EFIS-D10A and the panel. Place one of the 4 supplied mounting nuts on the end of each of the 4 studs protruding from the back of the panel. Secure the nuts tightly against the panel to complete the installation.
OPTION 2: FLUSH-MOUNT BRACKET
Make a rectangular cutout in your panel, ensuring that it allows the front panel of the EFISD10A to fit. The cutout required should have the dimensions 4.09” wide by 3.39” tall with corner radii of 0.125”. You also need to drill four 0.164” holes in your panel at the four locations shown on the diagram below (two above and two below the rectangular cutout). Install #6 plate nuts on the back side of the bracket. Place one of the supplied washers onto each of the four mounting studs on the EFIS-D10A and then slide the flush mount bracket over the EFIS-D10A. The bracket should wrap around the bezel of the EFIS-D10A. Place one of the 4 supplied nuts on each of the 4 studs and tighten the nuts. The EFIS-D10A/bracket can now be installed from behind your panel using the #6 screws through the previously drilled holes.

Instrument Installation
Connecting Static & Pitot Lines
The AOA, pitot, and static ports on the back of the EFIS-D10A are equipped with 1/8” NPT Female fittings. To attach your pitot and static lines to the back of the EFIS-D10A, 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-D10A, T’ing off of existing lines if performing a retrofit. View the following back view diagram the placement of your pressure lines.
The EFIS-D10A’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-D10A be connected to pitot and static systems in all installations.
Use two wrenches to both hold the brass fitting on the EFIS-D10A and secure the mating pressure line fittings to the corresponding locations on the back of the EFIS-D10A. Do not overtighten or allow the brass fittings to rotate.
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-D10A and any other instrument in your panel which requires it.

4. EFIS CALIBRATION AND CONFIGURATION
During manufacture, your EFIS-D10A underwent a comprehensive calibration, verification, and burn-in routine that minimizes setup time and ensures that your EFIS 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-D10A. This section takes you through these steps to make sure that you have properly installed and configured your EFIS-D10A.
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 EFIS > 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 EFIS-D10A’s internal sensors or remote EDC-D10A, you must configure the local magnetic inclination and magnetic intensity as described in the sections below.
In a DSAB network, the Bus Master’s heading is used as the only heading source for all connected instruments. However, in the event of a DSAB failure, EFIS instruments revert to their local heading source. In a system already using a shared heading, you may still configure and calibrate the local heading source. As soon as you bring up any of the magnetic calibration menus (MAGINC, MAGCAL, MAGADJ, MAGINT), the heading and DG displays switch to display the locally-derived heading indication. The display stays on that source until exiting the magnetic configuration menu. If you do not have an EDC-D10A connected, REMOTE COMPASS NOT DETECTED is displayed when in any of these menus.
EFIS-D10A Installation Guide |

EFIS Calibration and Configuration
SETTING MAGNETIC INCLINATION ANGLE AND INTENSITY (REQUIRED)
To calibrate your EFIS-D10A 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.
Obtaining Magnetic Inclination and Intensity

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. If you are near the equator or in the southern hemisphere, note that the inclination may be negative number.
Entering inclination and intensity into the EFIS-D10A
1.Enter the inclination setup menu by pressing any button beneath an EFIS page (except the far left or far right hotkeys), then MORE > SETUP > MORE > MORE > 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 MORE > SETUP > MORE > MORE > 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
EFIS-D10A (INTERNAL) HEADING CALIBRATION (ON GROUND AND IN FLIGHT)
NOTE: if you own the EDC-D10A Remote Compass Module, you do not need to perform this set of steps. Skip to the next section for calibration of the remote compass.
Because our goal is to give the EFIS-D10A a compass that is accurate in all attitudes, our user magnetic calibration process is more comprehensive than that for many other products. The magnetic field vector in North America is predominantly vertical; this requires that any complete calibration maneuver bank the aircraft significantly in order to accurately map out the unique magnetic signature of your plane in this three-dimensional field. Therefore, a large quantity of data needs to be recorded in a variety of
attitudes. Simpler calibration processes do not perform these steps and suffer by being accurate only at level attitudes. When properly completed, a magnetic calibration of this complexity will produce a compass that is accurate during banked maneuvers. Note that the EDC-D10A remote compass calibration process is not as complex because it is assumed that you have mounted it in a more magnetically clean environment. Three dimensional calibration has already been done on the EDC-D10A at the factory.
Before proceeding with the calibration, ensure that you have determined and entered the magnetic inclination (dip angle) as described above.
Performing the calibration
Perform the first portion of the heading calibration on the ground in an area where you can accurately determine magnetic North such as on a compass rose. You must also have enough room to perform a 540 turn on the ground as described below. Turn the EFIS-D10A on and let it warm up for 10-15 minutes before proceeding. Turn all instruments on that you would normally be operating during a flight, including the engine.
During magnetic calibration, do not turn the power off on the EFIS-D10A. This will cause any recorded compass calibration data to be lost; the calibration will need to be restarted.
1.Enter the EFIS calibration menu by pressing any button beneath an EFIS page (except the far left or far right hotkeys), then MORE > SETUP > MORE > MORE > MAGCAL. You should see a menu that reads GNDNRT, AIRRGT, and AIRLFT. If it reads NORTH, EAST, SOUTH, and WEST, you have the EDC-D10A installed and should proceed with the EDC-D10A heading calibration as described on the following page.
2.With the plane in the normal flight state (engine running, all instruments and avionics on), align the plane to point as close as possible to magnetic North. Press the GNDNRT button (the button’s text will toggle to DONE – do not press this until the maneuver is complete) and hold the plane still for 10 seconds. After the 10 seconds of holding still, maneuver the plane smoothly to the right through 540 degrees of heading change at a rate of 20 to 30 seconds per 90 degrees of change; the whole maneuver should take between 2 and 3 minutes. At the end of the maneuver, the aircraft will be pointing magnetic South. At this point, press DONE. If at any time, you make a mistake, press DONE, align the

aircraft to point to magnetic North and repeat the process, starting with pushing the GNDNRT button.
3.Now proceed to take off for the in-flight part of the calibration. After reaching a safe altitude, head the plane as close as possible to magnetic North. Press the AIRRGT button (again, the button’s text will toggle to DONE – wait until completing the maneuver before pressing this), and continue holding a steady North heading for 10 seconds. Then make a 30 degree banked turn to the right for 540 degrees. The maneuver ends with the aircraft pointing South. Fly the maneuver as smooth as possible since this will give you better results. At the end of the maneuver, while still pointing South, press the DONE button.
4.Maneuver the aircraft to point to magnetic North again. Press the AIRLFT button (toggling it to DONE – again, refrain from pressing until the maneuver is complete). Continue holding a steady heading (North) for 10 seconds, and then make a 30 degree banked turn to the left for 540 degrees. The maneuver ends with the aircraft pointing South. Fly the maneuver as smooth as possible since this will give you better results. At the end of the maneuver, while still pointing South, press the DONE button.
5.At any point in the calibration, you may redo a maneuver by pressing the appropriate button and repeating that step. The order in which you do the 3 maneuvers is not critical as long as all three maneuvers are performed completely without cycling the power to the EFIS-D10A.
6.When you are satisfied with the three maneuvers, press END. This will cause the EFISD10A to calculate the values needed for calibration. This process can take as long as 10 minutes, during which your EFIS-D10A will appear “frozen.” A message will be displayed onscreen: CALCULATING MAGNETIC CALIBRATION VALUES.
7.Wait for the message CALIBRATION COMPLETE before attempting to use the EFISD10A or remove power. Press BACK to leave the menu.
At this point the calibration is complete. We suggest you evaluate the performance of the EFISD10A heading feature, preferably on a compass rose, and decide if the performance is acceptable to you. If the resultant compass accuracy is not acceptable, you can either repeat the calibration process attempting to fly the maneuvers more smoothly, or purchase, install, and calibrate the Dynon Avionics EDC-D10A Remote Compass.
You will need to repeat this process anytime you move the EFIS-D10A to a new location in your plane or change the magnetic or electrical characteristics of the nearby environment (i.e. adding or removing other electrical instruments). Changing geographic location should have no effect on your heading readings after a user calibration.
Troubleshooting
During the calibration process you may receive one of the following errors. Next to each one is the corrective action required.
WARNING: MAGNETIC INCLINATION NOT SET. You have not entered the magnetic inclination into the EFIS-D10A yet. Please see the “Entering the Inclination Angle” section above.
