What engines does the EMS-D120 support?

We have sensor packages available for all Lycoming and Continental 4 and 6 cylinder engines, the Rotax 912 engine and the Jabiru 2200 and 3300 engines.

My engine is not on your list of probe packages. Will the EMS-D120 work with my motor?

Maybe. Consult our price list for a list of the sensors that we can supply. Note that our EMS is generally only compatible with the sensors we sell, though there are certain exceptions to this, including fuel level, tachometer, and the EGTs and CHTs. Give us a call at 425-402-0433 if you want to talk about your particular setup to discover if will work with our engine monitor.

What kind of fuel level senders does the EMS-D120 work with?

The EMS-D120 will work with any of the common “float” type resistive fuel senders. It can also work with capacitance type fuel probes as long as they output a voltage level between 0-5V DC.

How many EGTs and CHTs does the EMS-D120 support?

The EMS-D120 can be configured to monitor 2, 4, or 6 CHTs at a time. Does the EMS-D120 have a fuel computer?

Yes, when equipped with the optional fuel flow sender.

Do you have installation information available?

Mounting dimensions are available here . The installation and pilot's user guides and available in the documentation section of this website.

Can the EMS-D120 annunciate alarm conditions?

Yes. Practically every parameter that the EMS-D120 can monitor can be set to trigger alarm conditions at user-defined points. In addition to annunciating the particular alarm on the EMS-D120's screen, the EMS-D120 can output an audio alarm signal and can switch an externally powered panel light when alarm conditions are present. What is the difference between the EMS-D10 and the EMS-D120?

The EMS-D10 and EMS-D120 share the same engine monitoring electronics. The EMS-D120 has a 4” screen. The EMS-D120 has a 7” screen.

What is the operating temperature range?

The unit is specified to operate over the temperature range of -30 to +50 degrees Celsius. What is the input voltage range and the power consumption of the EMS-D120?

The EMS-D120 will operate from 10-30 V dc. Maximum power consumption is approximately 1.4 watts.

How much does the EMS-D120 weigh?

The EMS-D120 instrument by itself weighs 2 lb. 6 oz 1.33 kg). Additional weight will be incurred from wiring harnesses and engine sensors.

Can the EMS-D120 be used with turbine engines?

The EMS-D120 does not currently support turbine engines.

Will the instrument have an option to separate the display from the rest of the unit?

The EMS-D120 was conceived as a stand-alone instrument to allow for easy installation and compact size. There are no plans to provide for remote mounting of the electronics from the display.

Can the EMS-D120 connect to other instruments and avionics?

All Dynon Avionics products, with the exception of the early model EFIS-D10, can be connected to each other via the Dynon Smart Avionics Bus (DSAB) to share data with each other.

Exactly what features does the Dynon Smart Avionics Bus (DSAB) enable?

Broadly speaking, Dynon Avionics products connected via DSAB will be able to share data with each other. For example, in a cockpit that has an EFIS-D100 and an EMS-D120, both devices will be able to display EMS and EMS information, even simultaneously in a split-screen presentation if desired. Connected devices need not have the same screen size either: an EFIS-D100 and an EMS-D10, for example, can share display each others instruments as well.

How bright is the EMS-D120 screen? Can it be read in bright sunlight?

The EMS-D120 display brightness is rated at 400 nits. The colors used have been chosen to enhance the visibility under all light conditions. We believe the display to be usable under all light conditions, but have found the subject of screen brightness and usability to be very subjective. If you visit us at the major air shows we will take you outside with our products so that you can decide for yourself.

Is the EMS-D120 certified? Can it be used in a certified aircraft?

The EMS-D120 is not certified and we are not planning to certify this version of the instrument. Any use of the instrument in a certified aircraft would require you to work with the FAA on an individual basis (the "337" field approval process).

What is the resolution of your display?

The EMS-D120 display has a resolution of 854 horizontal by 480 vertical pixels.

Regarding the new generation products and their backwards compatibility with the existing products...What if someone wants the new system plus a D10A? Or, you have a D180 and want to display engine info on the new screen?

The EFIS-D100, EMS-D120, FlightDEK-D180, EFIS-D10A, and EMS-D10 will all still be for sale for the foreseeable future. We are not canceling any of our currect products. Over time, the D100, D120, and D180 will likely phase out in favor of the next generation system equivalents, which will have all of the same capabilities and much more.

All of our products will be supported for years - with repairs, technical support, and any bug fixes that are needed. There is no way that Dynon would ever stop supporting a past customer. We think one of the reasons we've been successful is that we've tried our best to support all of our customers, and that will continue to be the case. Call us with a question or a repair on a EFIS-D10, a product we haven't sold for over 4 years, and we'll still help with any question or problem you may have.

That being said, we are going to be winding down new feature development on the current series of products after the autopilot is released. After four years, we're reaching the limits of what we're able to do with the computing power in the current products. The major features that our customers have been asking for - such as synthetic vision, moving map, thin screens, etc - are not features that we can implement on our current hardware.

We've also learned a lot with the last generation of products, and to remain competitive we need to take all of that knowledge and translate it into the best avionics we can possibly build. To do this effectivlely and efficiently, we have we have to draw some lines between what we have now and what we'll be building next. For example, making DSAB work between the current and new products would be a huge software effort. If we put our limited resources there, development all of our products would slow down, and we're already a busy bunch over here.

We believe there's an easier way to cross the compatibility border, and that's the offer for trade-in credit on old units. If you are interested in the new system, then we'll take what you have and give you credit towards the next system. It's win-win: you get the new system, a new warranty, and we get to focus on our new product development.

We think that this trade-in program is a type of support that is uncommon in fast-moving technology (will Apple give you credit for your 2 year old iPod, or Dell for your old lappy?), but we want to do it anyway. We really do appreciate all of your business, and we want you to continue to grow with us. What's better than being sure that your past financial investment will continue to be an investment in the latest products from Dynon?

For those of us with existing engine monitors from Dynon, will the new generation products be backwards compatible with the connector and sensors?

The current EMS harness and sensors will plug right in.
