Any Dynon bus cable length would do, functionally you could use a 6' cable, if that is easier for your cable routing. Only depends on your panel layout. It could be that you want to be able to unscrew the Dynon unit and be able to move the unit out of the panel so you can reach the back an undo...

Regarding item 2: It partly depends on your configuration and you don't mention anything about engine or setup. For a regular setup the EMS controller gets pulses from the ignition system. In the configuration setting you will have to define how many pulses your system produces during one turn...

Please explain the problem a little more clearly. The Dynon GPS should not take that long a time to acquire a position lock not even from scratch (meaning therewas a long period between the previous lock and the new attempt). But note that it depend on when the last lock was acquired. What...

There is no special fancy graphics for the display of a cowl flap position. You can either use a numerical display or use on of the standard graphical display elements to indicate the current cowl position. You could pick one of the bar widgeets with only a single color (or maybe no color) or...

It seems as if there are multiple red X's stacked , maybe multiple defined items? It includes something with a reference to P24/25

As long as you have EMS inputs left over then you can monitor as many position indicators as you want. You dopn't even need the full Ray Allen servo, you can also use the Ray Allen resistive position indicator (that also is basically a 5 kohm potentiometer, just like the servos)

The resolution of the sensor display is set in the .sfg file, where all the different sensor functions are defined. For the specific sensor definition there is a parametero 'round=' that defines how many decimals will be used for display. If this is set to one then the display will only show...

Hopefully your issue can be resolved with a forced reload. But I had a problem, that looked very similar to your problem. My redundant redundant ADAHRS, would also be talking to the Skyvie display without problem (network connections worked fine), but it woudl complain about internal problems (I...

dbuds2, take a look at the answer from Preid:

It's just an extension of the Dynon bus, all the Dynon uniots (multiple displays, EMS, Arinc etc.) communicate through the bus and are very well capable of keeping the signals separated

That is strange, while testing my classic dynon screens the dimming is clearly coupled and the dimming only happens when the light sensors on both displays both are covered. I don't know how this information is shared though, Do you both have the Dynon bus and the Ethernet cable between the two...

If I click on the "official technical support channels" in the signature, I go to a page that shows dynon address and phone and email addresses, does that not happen for you?

Voltages that small can be hard to track down, it coudl just be a contact potential (different kinds of metals). AS long as you are sure that the battery is not draining all should be good, battery drainage can be measured by disconnecting one of the battery poles and then measuring the current...

It all depends on the kind of sensor (mechanism) being used and the valid input ranges defined - both the RPM sensor and the fuel flow sensor count pulses no pulses just means no RPM or no fuel flow (count revolutions of the little propellor inside the red block), no pulse just indicates no RPM...

A little confused as to what you are measuring. I woudl expect that a stray voltage should be measured in Volts (measure between aircraft ground (ground bus or FOS) and the master bus), a stray current on the other hand (current leakage if the main power relay is off) should be measured in mA...

I am not sure that you could decouple the battery sense in a similar way. But you might just try and use a general purpose diode, but it would have to be pointing from the battery to the EMS (which is the different direction of the diode that I used for the EarthX open collector status line)...

Do you have the EMS voltage sensor wired before the master solenoid? If this is the case then this voltage may be the result of feedback through the EMS, just like I had when I connected the EarthX battery status wire directly to the EMS

The default setup for the Dynon connects the RPM input simply to the magneto P-leads so there is no 'real sensor', but for different engine types any pulse generating sensor (or engine controller, that generates one or more pulses per revolution) may be used, and these can be connected to the...

There are cases where the backup batteries age and eventually don't keep enough charge anymore. But that woudln't explain why this is only happening to the primary display battery even when swapping the batteries. During the build of my second plane the Dynon's sat unused for a very long time...

There is a difference between the pressure sensors and fuel flow sensors. When pressure sensors are removed they don't produce the analog input value and the Dynon display can report this as a invalid value so the widget can be crossed out. For the fuel flow sensors, the sensor output gives a...
